Until that mechanism exists, the only safe change is an additive one through `db::ensure_column` (see the DB section); anything that renames, drops, retypes or moves a column or table is **blocked** on building schema versioning first, not something to do carefully by hand. A user's `{userid}.db` is SQLCipher-encrypted and readable **only while they are logged in**, so a migration cannot be a boot-time sweep over every file — it has to run per user, at unlock, and be idempotent.

Creating a user, deleting one, deactivating one, or changing a shared-folder/project membership all need Docker work (provision, tear down, stop, recreate with new bind mounts); enabling or reinstalling a connector needs live runtimes re-snapshotted. None of the endpoints that make those changes touches `ContainerManager` or the refresh helpers: each announces `SystemEvent::User{Created,Deleted,ActiveChanged,MountsChanged}` / `McpGlobalServersChanged` / `ConnectorReinstalled` **after** its DB write, and one subscriber — `skald::wiring::spawn_user_lifecycle`, spawned post-construction because it reacts through `Skald`'s own accessors, holding only a `Weak` — does the reacting, sequentially and best-effort. Being off the response path matters for `ConnectorReinstalled` in particular: it re-copies files and restarts servers inside every live user's container, seconds of work the admin's install no longer waits on. The payoff is that a *future* endpoint granting membership cannot forget to remount, because remounting was never its job. Reactions never block the HTTP response, and a failure settles at the user's next login or at boot reconciliation. + +**Where the bus stops: reconciliation rides it, authorization does not.** `SystemEventBus` is a lossy 64-slot broadcast whose contract is *"best-effort, settles at the next login"* — right for a stale mount, wrong for a revocation, where "settles later" *is* the failure. So deactivating or deleting a user splits in two: `Skald::revoke_user_runtime` runs **synchronously in the handler, before it responds** (revoke every session → evict + cancel the `UserContext` → `UserManager::lock`, in that order, so nothing is left querying a pool we then close and the DEK leaves RAM per §9), while only the container half — stop or remove — rides the bus. Before this, `active = 0` blocked the *next* login but left live sessions working: `login` checks the flag, `require_auth` only maps token → id. Same split for security groups (see the picker section) and for connectors, where the test is worth internalising because the call is literally the same function: `Skald::refresh_global_mcp_access` is **announced** (`McpGlobalServersChanged`) when a global connector is enabled or deleted — the first only makes something *appear*, the second is already enforced by `stop_server` — but **called directly** from `global_set_access` and `user_connectors_set`, where `set_access`/`set_for_user` *replace* a grant set and the refresh is what actually revokes.

See blueprint §19. + +**Boot unlocks the databases that have no key, and starts their runtimes.** §9 ties readability to a login, and for an encrypted file that *is* the mechanism — the key only exists once the password has been typed. For an unencrypted one it was a rule with nothing behind it: the data is already readable by anything in this process, so the only thing the login gated was the runtime. The cost was user-visible and looked like a bug — after every restart the Telegram bot answered *"your account is locked, log in via the web app"*, cron fired nothing and no background agent ran, until a human opened the SPA. So `Skald::new` calls `UserManager::unlock_all_unencrypted` (which registers the pools exactly as a login would, refusing an encrypted or inactive user), and `wiring::spawn_unlocked_user_runtimes` then builds a `UserContext` for each — **unlocking only makes the data readable; cron, the notify queue, the hub and the per-user MCP runtime all hang off the context**, so an instance is *working* only once those exist. That build is a background supervisor task, not part of `new()`: it starts every member's MCP servers inside their container, and the HTTP listener must not wait behind that. The same two steps run per user off the lifecycle bus (`UserCreated`, `UserActiveChanged{active:true}`, after the container `ensure`) so a member created at runtime does not wait for the next restart. Two boundaries are untouched and worth stating: **authentication is unaffected** (`SessionStore` sits above `UserManager`; no HTTP request authenticates as anyone because of this), and `open_unencrypted` still exists for the supervision path, still deliberately *not* registering its pool. The auto-unlock is deliberately not on a lazy path (e.g. inside `Skald::user_context`): `revoke_user_runtime` locks a pool synchronously and expects nothing to re-open it, so the writers of that map stay boot, login, and the lifecycle bus. Direction of travel, decided but not yet executed: strip the **power-user surface** (self-rewriting, arbitrary shell, dev-agent suite, ticket system) and move to a **binary-first** layout — the app is built once and run from a compiled binary, not executed from its own source tree. @@ -57,7 +79,7 @@ Two rules keep the boundary real, and both are enforced by the compiler: - **The core never names a plugin.** A plugin contributes tools through `Plugin::tools(self: Arc)` — the sibling of `http_router()` — so nothing in the core has to downcast to a concrete type. Naming one would drag every plugin in the tree into the core, including a C build via `plugin-transcribe-whisper-local`. - **The core never learns about the process shell.** There is no in-core restart hook — the former `restart` tool and its `tools::restart::set_restart_handler` seam were removed. The only coupling to the supervisor is now the `run.sh` exit-code protocol (exit `255` ⇒ re-exec the same binary by path), a seam no code currently triggers (kept for a future admin-driven restart). The live expression of this principle is `skald_core::boot`, which emits startup lines each shell renders (`src/boot_format.rs` here). -**Plugin visibility & per-user config.** The admin surface is split in two: `#plugin-catalog` (`plugin-catalog.js`) is a status board — one card per plugin with an enable toggle + health dot + a Configure button — and `#plugin-detail?id=` (`plugin-detail.js`) holds the instance-config form + per-user access checklist for one plugin (the plugin counterpart of `connector-detail.js`). The user-facing half is `#plugins` (`plugins-page.js`): granted plugins + their per-user config forms. Enable/disable + instance config + access grants are gated by the `plugin.manage` capability (admin-only by construction). Visibility is **opt-in**: a row in `plugin_access(plugin_id, user_id)` grants a user sight of an enabled plugin (`plugin_id` is bare TEXT, never a FK — a `plugins` row exists only after the first toggle). A plugin with a non-empty `Plugin::user_config_schema()` exposes per-user settings, stored in `plugin_user_configs` (**admin-readable system.db — never secrets**) and applied through the `Plugin::update_user_config` hook, whose default just stores the blob via the `PluginUserConfigApi` on `PluginContext.user_config`. Telegram is the reference impl: the user pastes the bot's pairing code in their Plugins page, the override turns it into a `chat_id → user_id` binding (same write path as the `telegram_pairing` tool) and stores a `{linked, chat_id}` status blob for the UI. Endpoints: admin `GET/PUT /api/plugins[/{id}]` + `GET/PUT /api/plugins/{id}/access`; user `GET /api/plugins/mine` + `PUT /api/plugins/{id}/my-config`. +**Plugin visibility & per-user config.** The admin surface is `#plugins` (`plugin-catalog.js`), a status board — one card per plugin with an enable toggle + health dot + a Configure button — plus `#plugin-detail?id=` (`plugin-detail.js`), which holds the instance-config form for one plugin (the plugin counterpart of `connector-detail.js`). **Granting is user-side, exactly like a connector grant**: the checkboxes live in the **Plugins** section of `#users/{id}` (`users-page.js`), right below that person's connectors, and the plugin's own page keeps only a read-only roster of who holds it, linking there. The question an admin asks is "what may this person use", and answering it plugin-by-plugin meant opening every plugin in turn; one write path also means the two surfaces cannot disagree. Unlike an MCP grant — which gates a runtime snapshotted at login and so needs a synchronous revoke — a plugin grant is re-read from `plugin_access` on every request that depends on it (sidebar pages, `/plugins/mine`, and each inbound channel message: Telegram checks it per message), so a revoke lands with no push and nothing on the bus. Binding-managed plugins (`Plugin::manages_own_access`, e.g. mobile-connector) are absent from the user-side list and rejected by its writer — a box that controls nothing is worse than no box. There is **no generic per-user plugin page**: a plugin with per-user settings (Telegram's pairing, Honcho's opt-in) hosts them in its own sidebar page via `Plugin::web_pages()`, like mobile-connector. Enable/disable + instance config + access grants are gated by the `plugin.manage` capability (admin-only by construction). Visibility is a row in `plugin_access(plugin_id, user_id)`, which grants a user sight of an enabled plugin (`plugin_id` is bare TEXT, never a FK — a `plugins` row exists only after the first toggle); the table is deny-by-default but the rows are **written for you at install time** — see the default-access section below. Per-user values are stored in `plugin_user_configs` (**admin-readable system.db — never secrets**) and applied through the `Plugin::update_user_config` hook, whose default just stores the blob via the `PluginUserConfigApi` on `PluginContext.user_config`. Telegram is the reference impl: its pairing page (a `web_pages()` fragment with no backend of its own) reads the `{linked, chat_id}` status blob from `GET /api/plugins/mine` and submits the code through `PUT /api/plugins/{id}/my-config`; the override turns it into a `chat_id → user_id` binding (same write path as the `telegram_pairing` tool).

The router contract: cheap and safe to build pre-start, handlers tolerant of the not-running state (resolve runtime state per request through a shared cell, as mobile-connector does). A plugin may also contribute **frontend pages** via `Plugin::web_pages()` (`PluginPage { page_id, title, icon, entry, admin_only, priority }`): `GET /api/plugins/pages` returns the caller's visible pages (admin: all; others: non-`admin_only` pages of granted, enabled plugins) with `entry_url` resolved, and the sidebar renders them as menu entries routed `#plugin//`. A single `` (`web/components/plugin-page-host.js`) dynamic-imports the fragment ES module the plugin serves from its own router, registers its default-exported HTMLElement class, and mounts it with the `plugin-id` attribute — the fragment talks to its backend only through `/api/plugin//…` and runs with full session privileges (plugins are trusted: they ship in the binary).

Used for the OAuth columns on `mcp_catalog` / `mcp_user_servers`. Anything destructive waits for real versioning. **No foreign key in the owner bucket may point at a registry table.** SQLite cannot enforce a key across files, not even through `ATTACH`, and sqlx turns on `PRAGMA foreign_keys`: the `CREATE TABLE` succeeds and every `INSERT` fails. `db::tests::owner_tables_stand_alone_with_foreign_keys_on` enforces this by running the owner schema against a database holding nothing else, then inserting a row into each table. One key crossed and was fixed: `chat_history.model_db_id` (dropped — write-only, and `llm_requests.model_name` already records the model). **Memory namespace (blueprint §5).** `memory_docs` (accessor `db/memory_docs.rs` — `get`/`upsert`/`list`/`search`(FTS)/`delete`) backs a virtual note store surfaced through the fs-tools, **not** the disk. Two sibling roots (not the blueprint's nested `memory/{userid}` + `memory/shared`): `user-memory/…` routes to the caller's own pool (`ToolContext::pool`), `shared-memory/…` to the system pool (a singleton captured in `fs::register_all`). `tools/fs/classify_memory()` decides on the raw first path component (a `..` in the tail clamps inside the store, never escapes to disk); `read_file`/`write_file`/`list_files`/`edit_file`/`insert_at_line`/`replace_lines`/`search_file` override `run_with` to route memory paths (each extracting a pure transform shared with its on-disk `execute`) and leave every other path on disk. The HTTP surface routes them the same way: `GET /api/file` classifies **before** `resolve_view_path` and serves the note from `memory_docs` (caller's pool / system pool), so the file viewer opens `user-memory/…` and `shared-memory/…` like any file, and `show_file_to_user` accepts memory paths too (existence-checked on the right pool). Approval (seeded in `seed_fs_path_rules`): `user-memory/*` is `@fs_any allow` (private, frictionless); `shared-memory/*` is `@fs_read allow` + `@fs_write require` — reads free, **writes need approval** so the agent can't silently push one person's data into shared memory. `grep_files` stays disk-only (regex-across-tree ≠ FTS); ranked full-text recall over notes is a separate tool, `memory_search` (`tools/fs/memory_search.rs`), over the `memory_docs` FTS index — allowed by a path-less rule (it takes `query`, not `path`). -**Memory injection into the prompt**: `MessageBuilder::load_inject_memory` routes each `meta.inject_memory` entry — `user-memory/…` → owner pool, `shared-memory/…` → the shared (`system.db`) pool, both via `memory_docs::get`; anything else (`data/…`, `$WD/…`) is a disk read. The shared pool is threaded `ChatSessionManager` → handler → `MessageBuilder`. `assistant` and `project-coordinator` inject `user-memory/index.md` + `shared-memory/index.md`. +**Supervision + coverage (registry).** `supervision(subject_user_id, supervisor_user_id)` (accessor `db/supervision.rs`) is the §0.1 **supervision edge** — a generic directed edge between two users, deliberately attribute-free, whose domain reading ("a parent watches a child") lives only in seed data and UI copy. It answers two questions with one table: *whom does a background agent look at* (`subjects()`) and *who may read what it produced* (`supervisors_of()`, which is what `reports.audience = 'supervisors'` resolves against). Both FKs are registry→registry, so the cascade is real in both directions. `system_agent_coverage(agent_id, subject_user_id, covered_through)` (accessor `db/system_agent_coverage.rs`) is the per-subject watermark that makes "everything since last time" a window: it sits between `system_agent_runs` (a history for the human, skips idle passes) and `system_agent_state` (attempt marker, advances on **every** tick and **before** the work — which is precisely why it can never delimit the window the work is about), and differs from both by advancing **only on a completed pass**, so a crash re-covers rather than skips. Deriving it from the last report's `period_end` was the obvious alternative and is wrong for one ordinary reason: a supervisor deleting an old report would rewind the scheduler and regenerate the report they just discarded — a document is the user's to delete, scheduler state is not. Registry rather than owner because the pass runs in *some* supervisor's runtime and which one depends on who is logged in that night; the acting user's file would give one subject two unsynchronised clocks. -**Prompt substitutions**: an `AGENT.md` may carry `` placeholders; `agents::resolve_includes` turns each into a `__KEY__` sentinel, replaced at request time. Two are **builder-side** — `MessageBuilder` resolves them itself from the session owner (`user_id`) + registry (`shared_pool`), so every source (WS, mobile, cron, sub-agents) gets them with no caller plumbing: `__SHARED_FOLDERS__` (the user's shared-folders table) and `__USER_PROFILE__` (the owner's directory profile: `Name`, `Date of birth` with age computed at build time, `Sex`, `Preferred language`, admin `Notes` — unset values render as explicit `unknown` / `not specified`, the `Notes` line is omitted when empty). Any other key comes from the per-call `SendMessageOptions::system_substitutions` map. +**Reports (`db/reports.rs`, blueprint §13).** The documents system agents write about a stretch of time — a daily review of a supervised account, a weekly "what you struggled to get done" digest. **The second two-homes table**, for the same reason as `memory_docs` and with the same mechanics: one owner schema, and the file a row lands in *is* its audience. A `{userid}.db` row is that user's own report, behind SQLCipher; a `system.db` row is an instance report, written *about* someone *for* the people who supervise them and therefore cleartext to whoever owns the box — deliberately, since they are the intended reader (§2). Which file a producer writes into falls out of its own `AgentScope` with no new concept (`PerUser` → `ctx.pool`, `Instance` → the registry pool it already holds), and **the subject of an instance report cannot see it** because their tools only ever reach their own pool — the invisibility is structural, so nothing anywhere filters by reader. `subject_user_id`/`producer_user_id`/`run_id` are bare snapshot columns, never FKs (owner→registry would fail every INSERT; for an instance row the `system_agent_runs` trace sits in the *acting* user's file). `kind` is producer-declared text, not an enum (§0.1). Rows are immutable but for `mark_read`, whose `read_at IS NULL` guard makes acknowledgement **shared and first-reader-wins** — two admins, one alert, dealt with once. Consequence worth internalising: since the admin cannot open the subject's encrypted sessions, **there is no click-through to the evidence** — whatever justifies a report must be narrated in its body, under the same rule the shared memory lint already follows (say which conversation and what kind of problem, without reproducing the sensitive line). **Currently there is no producer, no API and no UI** — the table, its accessor and its tests are the whole of it. -`system.db` still gets **both** bucket functions — but no longer because the migration is unstarted. It gets the owner schema because it *is* the owner of **shared** memory (`memory_docs`) plus, for now, the globally-scoped `secrets` and the `mcp_events` lifecycle log (`SecretsStore` and the global `McpManager` are built on the system pool and shared by reference into every `UserContext`; the global runtime's *config* now lives in the registry table `mcp_global_servers`, and per-user connector config in each user's owner `mcp_user_servers`). Every *other* owner table is created there but never written to anymore — the global owner-bound managers that would write them (chat/jobs/etc.) are inert (see "Current state").

Docker is **required**: a missing daemon fails `Skald::new` and the process exits. **What goes in the image vs. what the agent installs on demand** is a real trade, and the Dockerfile states its rule: `sudo apt-get install` works in the sandbox but re-runs on **every container recreate**, inside a task, where it costs latency and can fail — while the image is **one, shared by every container**, so preinstalling costs its size once for the whole box. Anything an agent reaches for repeatedly is therefore baked in; `build-essential`/`python3-dev` and `pandoc` are deliberately left out as big *and* self-recoverable.

Since the same tree is writable from inside the container, a symlink planted there that points outside the home/shared root is caught here — the host-side tool never escapes the user's workspace. `grep_files` stays disk-only (regex ≠ FTS; memory → `memory_search`) but resolves its root the same way. `execute_cmd`'s `workdir` is an agent path mapped to its container path via `UserFs::to_container`. +**The security boundary is the container, not the mounted subtree — the mount is the *fast* path, not the only one.** An agent already reaches every corner of its container through `execute_cmd`, which runs there with passwordless `sudo`; fs-tools that stopped at the mounts were not protecting anything, they were offering a poorer view of the same sandbox, and the model answered that by shelling out (the observed failure: `read_file /tmp/cv.txt` → *"path escapes your workspace"* → the agent re-read it with `cat`). So `resolve_target` routes a physical path to one of two backings. An **absolute** path is container vocabulary — it is what `execute_cmd` prints — so it is reverse-mapped through `UserFs::container_to_agent` first: landing on a mount takes the host path (**`/root/x` *is* `~/x`**, which the tools used to reject outright, since `PathBuf::join` with an absolute tail silently discards the base and the result then failed the prefix check); landing nowhere means it exists only in the container, and `container::exec_fs` acts there over `docker exec` (paths passed **positionally** as `$1`, so a path containing `$(…)` is data, not syntax). Membership is not bypassed: `/root/shared/{X}` for a non-member still resolves to the same error as `shared/{X}`. -The threading: `UserContext.fs` (built by `container::build_user_fs` at login, snapshotting shared memberships) → `ChatSessionManager` → `ChatSessionHandler.fs` → `ToolContext.fs`. **Admin CRUD is wired** (`src/frontend/api/shared_folders.rs` — `GET/POST /api/shared-folders`, `PATCH/DELETE /api/shared-folders/{id}`, `POST`/`DELETE .../members[/{user_id}]`; UI `shared-folders.js`): a create/describe/delete + per-member `can_write` surface, and each mutation calls a best-effort `remount(user)` that rebuilds the affected user's fs + container mounts **in place** — so a membership change lands without a re-login (blueprint §6's "admin CRUD" + "membership refresh without re-login" TODOs, now closed; it still settles at next login/boot if the live remount fails). `execute_cmd` /stop is robust: the command runs under `setsid -w` in its own process-group (leader pid recorded in a container pidfile), and a `KillReaper` drop-guard reaps that group on /stop **or** timeout via a detached `docker exec` that walks `/proc` and kills members by **positive pid** (the container's dash mishandles `kill -`); the pidfile is passed positionally (`$1`), and the container's `--init` (tini) reaps the killed processes so no zombies accumulate. **Per-user MCP connectors now run inside this container** (§7) — the container infra enabled it; see the MCP connectors section. +**One implementation per tool, not two.** Every single-file fs-tool already funnels through the same shape — resolve, then run a sync `execute` over one absolute host path — so the container branch is a **shuttle** (`fs::Shuttle`, behind `fs::run_physical`): pull the file out of the container, run the *unchanged* tool on the copy, push it back if the content changed (compared by bytes, not mtime, whose one-second resolution would miss a fast edit). Nothing about a tool's messages, diffs or pure transforms is duplicated. A missing remote file is deliberately **not** pre-created — `write_file` reports "Created" vs "Overwrote" from whether the path existed, and a placeholder would make every creation lie. Three tools opt out of the shuttle because a single file is the wrong unit: `list_files` lists in place via `exec_fs::list` (`find -printf`; `line_count` is omitted, since counting lines would turn a listing into a `docker exec` per file), `read_file` reads container paths as text (a shuttled copy is gone by the time the projection would inline a `MediaRef`, so media stays a mount-only feature), and `grep_files` **refuses** container paths with a pointer to `execute_cmd` + `rg` — its regex flavour, glob, windowing and offset would all have to be re-derived from ripgrep's flags, and a grep that answers *almost* the same is worse than one that says where to go. The viewer follows the same routing through `resolve_view_target` (`GET /api/file` and `show_file_to_user` open container paths; served without an ETag, so the editor stays read-only there). + +**The memory roots are signposted inside the container, not merely absent.** `user-memory/`/`shared-memory/` are virtual, so nothing of them existed on disk — and the nothing was worse than it sounds: `cat user-memory/x.md` returned a bare ENOENT (which reads as *the note is missing*, not *wrong door*), while `mkdir -p user-memory && echo … > user-memory/x.md` **succeeded**, writing a real file into the home that no reader ever visits and that the next `ls` then confirms as if it had worked. Each root is therefore a **read-only bind mount** (`{WD}/.memory-signpost/{root}` → `{container_home}/{root}:ro`, gitignored, rewritten from consts on every `ensure`) holding a README that names the tools. Read-only *as a mount*, not as a mode: the container user has passwordless `sudo`, so a `chmod` would be a suggestion, whereas `:ro` holds — remounting needs `CAP_SYS_ADMIN` (verified: write, `sudo` write, `sudo chmod`, `sudo mount -o remount,rw` and `sudo rm` all fail). A README rather than an empty dir because `Permission denied` is an error, not an instruction — models answer it by reaching for `sudo`; the README puts the correction in the directory the failing command just named. These mounts are deliberately **not** in `UserFs`: they back no agent path and the host-side fs-tools must never resolve into them. They are the **fourth self-heal axis** in `reusable()` (`signposts_mounted`) rather than an `IMAGE_TAG` bump, since the image is unchanged and a bump would make every box rebuild it to fix a mount. The matching half is in `classify_memory`, which now strips the home spellings (`./`, `~/`, `/root/`) before matching the root — without it `~/user-memory/x.md` missed the match, fell through to the disk router, and became exactly the invisible physical file the signpost exists to prevent. + +**Skills are a read-only tree with two scopes, and the space *between* them is closed too.** `skills/shared/{id}` is the group's, `skills/{username}/{id}` is one member's own (`core-api`'s `SkillMounts`; agent path on the username like `projects/`, host path on the stable userid). Everything under `skills/` is read-only in **both** directions — `:ro` bind mounts and `can_write_to → false` — because these hold installed artefacts, not working files: a skill body is *read as instruction* by whoever it is visible to, so writing one is a decision that must pass a gate, not a file write — the one door is `skill_register` (with `skill_delete` and `list_items(type="skills")`), called from the chat and gated `require`; a public repo is fetched with `fetch_repo` and then registered. Two traps, both closed together and neither covering the other's half. **Host-side**, the `skills` arm of `can_write_to`/`host_base_and_tail` spans the **whole root**, not the two known scopes: the fallthrough answers `true`/home, so an invented scope segment (`skills/pippo/SKILL.md` — the *likely* guess, not the lucky one) would land in a physical directory under the home that no indexer ever reads. That is the memory-signpost failure exactly. **In-container**, the defect is structural rather than name-dependent: the scope mounts nest inside `container_home`, so `/root/skills` would be a real directory inside the *writable* home mount and `mkdir -p ~/skills/pippo` would succeed. Hence a third mount: `{WD}/.skills-root/{userid}` → `{container_home}/skills:ro`, holding the signpost README plus the two scope mountpoints. That root is **per-user and materialized whole** (`container::ensure_skills_root`) because Docker refuses to create a mountpoint inside a `:ro` mount — `shared/` and `{username}/` must already exist in the root's own source, and one of those names is the member's — which is also why the three host paths are one `SkillMounts` field rather than three `Option`. `mounts()` emits them root-first; `skills_mounted` is the **fifth self-heal axis**, for the signposts' reason. A stale scope dir left by a rename is pruned at each `ensure`. The bare-id alias `skills/{id}` (the shortest spelling, so the one a model writes unprompted) resolves in `resolve_skill_alias` — **only** when the id is unique across the two trees, failing loudly with both full paths otherwise, since a personal skill silently shadowing a group one is a divergence nobody chose. `UserFs` stays pure: it returns `RouteError::SkillAlias` and skald-core does the probe. + +**The skills index is generated, and the sentinel is the knob.** What reaches the model is not a file anyone maintains but a **function of the two trees** (`crates/skald-core/src/skills/`, pure functions in the shape of `LlmCommandManager`): each skill's `SKILL.md` **path** plus its frontmatter `description`, truncated to 200 chars, under an imperative header ("you MUST read its SKILL.md") — the countermeasure to the real failure mode, which is the model *under*-triggering. Printing the full path rather than an id plus a composition rule is what makes a read tool unnecessary: `read_file` on the printed path is one call, and there is no step left for the model to get wrong. Injection is the placeholder `` (normally ``, a fragment that holds **only** the sentinel), substituted in `AgentSystemContext::build_base` beside `__MCP_LIST__`; `resolve_includes` needs no branch, its generic `` → `__KEY__` arm already covers it. There is **no `meta.json` flag** — the sentinel *is* the switch, so the four `type: system` agents opt out by not including the fragment (an imperative "read it with read_file" is exactly wrong in an unattended turn, and some of those run with `allow_tools: false`). All eleven `chat`/`task` agents carry the include, sub-agents included: in a delegation the one doing the work is the child. Three rendering rules are load-bearing and each closes a specific failure: a **stable order** (scope, then id) because the index sits inside the provider's cache key; a **deterministic tail cut** at an 8 KB budget, announced by a `[N more skills omitted]` line, because a silently truncated index has the model conclude in good faith that a skill does not exist; and **empty in, empty out** — every word of prose lives inside the render, so an instance with no skills spends zero tokens and leaves no orphan sentence (the MCP list is the counter-example: its prose sits *around* the placeholder, and the empty state once had the model inventing a discovery tool). A colliding id is marked `[name collision]` on **both** lines, never shadowed. A malformed skill is skipped with a `warn!`, never fatal — the index is built while assembling a prompt. Freshness has two doors, one per writer. The in-process tools invalidate directly (`Skald::invalidate_prompt_prefix`, called by `skill_register`/`skill_delete`); a hand edit on the box is caught by the **skills watcher** (`skills/watch.rs`, spawned from `spawn_background`): a recursive `notify` on `{WD}/skills` + `{WD}/skills-users`, debounced ~800 ms, that re-digests each touched tree (`skills::tree_digest` — the (id, description) pairs the index is made of) and emits `SystemEvent::SkillsChanged { scope }` only when the digest moved. The subscriber `spawn_skills_freshness` (next to `spawn_user_lifecycle`, same `Weak` shape) maps the scope and calls the same invalidate accessor. Editing a script leaves the digest byte-identical and announces nothing — which is exactly the §6 rule, so an invisible change costs nobody a cache miss. Two gotchas the code carries comments for: the watcher **canonicalizes `{WD}`** (FSEvents reports real paths, and `/var` is a symlink on macOS), and it creates the two trees if absent (a box before its first user has neither). + +**The sandbox command list is a discovery hint, and the tool — not the sentinel — is the knob.** `container/commands.rs` probes the user's container at login (`UserContextFactory::build`, right after `ensure()`, **non-fatal**) with one `docker exec` running `command -v` over a curated ~35-entry `PROBE_ALLOWLIST`, and the result rides `LoopConfig.sandbox_commands` → `AgentSystemContext` → `__SANDBOX_COMMANDS__`. Three decisions carry it and each is the answer to an obvious-looking alternative. **The allowlist is the curation, and the probe is there so the list cannot lie** — not the other way round: a full `PATH` dump is 800 entries of coreutils noise, so what is worth tokens is decided by hand, and `command -v` exists only so we never announce something a container recreate threw away. A tool outside the list therefore never appears, which is fine because **the rendered prose says the list is partial and names `command -v`** — an inventory the model reads as exhaustive is the failure this shape avoids, the same one the skills index's `[N more skills omitted]` line closes. Order is the allowlist's own (grouped by kind of work), never sorted: the grouping *is* the curation, and the reader is a model, not a `grep`. **Staleness is cheap in both directions**, which is why there is no refresh machinery at all: a mid-session install is known to the agent that ran it, and a container recreate costs one `not found` plus the `apt-get install` the agent was already able to do. Gating is the one part that is not the skills pattern: every `AGENT.md` carries ``, **including the four `type: system` ones**, and the section is emitted iff the turn's model is shown `execute_cmd` — computed from `allow_tools` plus the security group's visibility filter (`session/handler/config.rs`) for a root turn, and from `child_defs` for a sub-agent, i.e. always from *the same definitions the model will see*. Hence `has_execute_cmd` is in the `PrefixCache` key: the group is switchable mid-conversation from the chat's shield pill, and keying on it costs nothing because that switch already rewrites the tool payload sitting in the same provider cache. The fragment holds only the heading and one stable sentence; **every conditional claim lives in the renderer** (a departure from the `__MCP_LIST__` shape it otherwise follows), because prose promising `sudo apt-get install` is not the renderer's to retract when the tool is absent. Three rendered cases, and the middle one is why this is not a one-liner: the list, the *unreadable-probe* line (empty ≠ bare sandbox — rendering nothing under a heading that promises a list is how the MCP section once had a model invent a discovery tool), and the no-`execute_cmd` line. `execute_cmd`'s own description deliberately carries **no** capability advertisement — its `(python + node available)` was removed when this landed, since its job is steering the model *away* from the shell for work a file tool does better, and the two messages dilute each other. + +**Containment** (`resolve_host_path`) is unchanged and still guards **the host branch**: every path that lands on a mount is canonicalized (following symlinks) and prefix-checked against its mount base, **fail-closed**. That check is what it always was — the defence against a symlink planted from inside the container pointing at the **host's** `/etc`, which the host-side tool would otherwise follow off the box. Opening the container branch does not weaken it: that branch never touches the host filesystem, so there is no host to escape from, and the check keeps applying to everything mounted. `grep_files` stays disk-only (regex ≠ FTS; memory → `memory_search`) but resolves its root the same way. `execute_cmd`'s `workdir` is an agent path mapped to its container path via `UserFs::to_container`. + +The threading: `UserContext.fs` (built by `container::build_user_fs` at login, snapshotting shared memberships) → `ChatSessionManager` → `ChatSessionHandler.fs` → `ToolContext.fs`. **Admin CRUD is wired** (`src/frontend/api/shared_folders.rs` — `GET/POST /api/shared-folders`, `PATCH/DELETE /api/shared-folders/{id}`, `POST`/`DELETE .../members[/{user_id}]`; UI `shared-folders.js`): a create/describe/delete + per-member `can_write` surface, and each mutation emits `SystemEvent::UserMountsChanged`, on which the lifecycle reconciler runs `Skald::refresh_user_mounts` — rebuilding the affected user's fs + container mounts **in place**, so a membership change lands without a re-login (blueprint §6's "admin CRUD" + "membership refresh without re-login" TODOs, now closed; it still settles at next login/boot if the live remount fails). `execute_cmd` /stop is robust: the command runs under `setsid -w` in its own process-group (leader pid recorded in a container pidfile), and a `KillReaper` drop-guard reaps that group on /stop **or** timeout via a detached `docker exec` that walks `/proc` and kills members by **positive pid** (the container's dash mishandles `kill -`); the pidfile is passed positionally (`$1`), and the container's `--init` (tini) reaps the killed processes so no zombies accumulate. **Per-user MCP connectors now run inside this container** (§7) — the container infra enabled it; see the MCP connectors section. ## Projects -A **project** is a shareable, self-service workspace: a folder at `{WD}/projects/{owner_userid}/{slug}` plus membership in the registry. `projects` (accessor `db/projects.rs` — slug is immutable, `UNIQUE(owner_user_id, slug)`) + `project_members` (junction with `can_write`; the owner is always a write-member, so a private project = one member).

Every call site therefore checks existence **before** its upsert (`is_new_row` / `is_new_server` / `is_new_entry`) — a re-install or an edit seeds nothing. Seeding is additive-only and idempotent on the PK, which is why every call site is best-effort (a `warn!`, never a failed request): a grant that did not get written is fixable from the user's page, and nothing here can ever widen further than the two moments allow. + +**Who is included is a role attribute, not a role id** (§0.1): `roles.attrs.auto_grant`, parsed by `RoleAttrs` like everything else there. It defaults to **`true`** — hence the hand-written `impl Default for RoleAttrs`, since a derived one would give `false` and silently invert the feature for every role predating the attribute. The seeded `children` preset sets it to `false`, which is the whole reason the attribute exists. `admin` answers `false` too, but as a *skip*, not a denial: admins hold everything implicitly (`plugin_access::effective_access` short-circuits), so rows for them would only be noise in every roster.

One thing sets it today: a binding-managed plugin (`Plugin::manages_own_access`, mobile-connector) is marked `0` at row creation, because it never reads `plugin_access` and rows for it would make its roster claim an audience that means nothing. There is no UI for the flag yet — `access_defaults::set_grant_by_default` is the seam when one is wanted. Changing it is deliberately **not** retroactive in either direction. + +**A role change does not re-seed.** Promoting a child to an adult role leaves their grants as they were; the admin ticks the boxes once on that person's page. Deliberate: the reverse (demotion) would then have to *revoke*, and a revocation that fires as a side effect of an unrelated edit is exactly the class of surprise the two-moment rule exists to avoid. + +## System agents (event triage, memory lints) + +A **system agent** runs on a user's behalf without being asked. There are three — event triage (the background event processor) and the two memory lints — behind **one** scheduler, and the machinery is deliberately shaped so a fourth is a trait impl plus one line in a registry. + +**The unit of work is one agent for one user**, and every part of the design falls out of that. the triage agent's events (`mcp_events`) are in the caller's own encrypted database, pushed there by connectors in the caller's container; the notification goes to the caller's hub; the trace (`system_agent_runs`) is in that same file. So an agent owns **no timer and no user list**: it implements `SystemAgent` (`crates/skald-core/src/system_agents/`) — `has_work` + `run` over an `AgentRunCtx` unpacked from that user's `UserContext` — and `skald::wiring::spawn_system_agents` decides who and when. Building it against the ownerless `Conversation` bundle was exactly what made the pre-multi-user version inert: it wrote sessions into `system.db`, notified a hub with no subscribers, and resolved tool paths against a container that does not exist. + +**One loop for cadences three orders of magnitude apart.** Event triage runs every few minutes, a lint weekly — the case that tempts a second loop. It stays one because the wake-up decides nothing: `base_tick` (min enabled interval, clamped to [60s, 15min]) only picks how often to *look*, and whether an agent runs for a given user is `system_agents::is_due` against persisted state. A second scheduler would be a fourth global bus in disguise. + +**Due-ness is persisted, not counted from boot** — the new owner table `system_agent_state(agent_id, last_attempt_at)` (accessor `db/system_agent_state.rs`). It is deliberately **not** `system_agent_runs`: the run log is a history for the human and skips idle ticks, while scheduling needs *every* attempt, so reading due-ness off the log would re-run an idle agent every tick and never bring a weekly one due once its last productive run aged out. Persisting it is also what makes a long interval survive a restart — an in-memory deadline is fine at event triage's scale but a weekly agent on a box rebooted every few days would have it re-armed before it ever fired, and would simply never run. Side benefit: a user who logs in after a long absence is picked up on the next pass. + +**`run_and_record` orders the three steps, once, for everybody**: mark the attempt (always, even for an idle pass) → `has_work` (`false` writes nothing at all, or the run log becomes a heartbeat) → open the run row, then work. The `start`/`finish` split (unlike `job_runs`, written once at the end) leaves a visible `running` row when the process dies mid-pass, swept to `failed` by the next `start` for that agent — safe precisely because the scheduler is sequential and single-instance, at both levels (agents in order, then users in order). + +**`AgentScope::PerSubject` is the scope where "whose data" and "whose runtime" come apart** — the conversation review (`system_agents/conversation_review.rs`, wiring `subject_pass`) is the first and the reason it exists. The pass reads the **subject's** database and runs inside a **supervisor's** runtime, so everything it leaves behind (ephemeral session, run row) lands in the watcher's file and nothing in the watched one's; the report crosses between them via `system.db`. Three things fall out and each is load-bearing: (a) **iteration is over subjects, not supervisors** — two parents watching one child must yield one review, so whichever of them is unlocked lends a runtime and the report is filed against the subject; (b) **`is_due` is not consulted** — it keys state by agent within one file, which would collapse every subject sharing a supervisor into one clock, so due-ness lives in `system_agent_coverage` and is answered inside `has_work` (and `run_and_record` skips `mark_attempt` for this scope for the same reason); (c) **the subject need not be logged in**, via the new `UserManager::open_unencrypted` — for a user with no key the password guards the *session*, not the data, so this makes that explicit in one place and **refuses an encrypted user**, not as policy but because there is no key to be had. The rule that falls out is neutral by construction and worth quoting: *work over somebody else's history runs unattended for a user who is not encrypted, and only while they are logged in for one who is*. The returned pool is deliberately **not** registered as unlocked (that map is what "logged in" means to everything else). Authorization is the caller's: `subject_pass` is behind the `supervision` edge, never a role check. + +**`meta.json: "allow_tools": false` empties the turn's tool set** (`AgentMeta::allow_tools` → `loop_adapters/runtime.rs::turn_params` swaps in an empty `ToolRegistry`): built-ins, MCP, plugin and interface tools alike, `notify` included. Distinct from a restrictive security group — a group decides whether a call is *allowed*, this decides whether the model is shown anything to *call*. For an agent whose input is other people's text, that is also the prompt-injection answer: the round an injected instruction would act in has no tools in it. The conversation review declares it, and consequently produces its report as the turn's **final assistant message** (read back with `chat_history::last_assistant_for_session`, parsed shallowly by `parse_report`: leading `# heading` → title, opening paragraph → summary, `NOTHING_TO_REPORT` sentinel → no row) rather than through a `save_report` tool, which would have needed whitelisting past the approval gate that an unattended pass auto-denies. The cost is that severity cannot come from the model; every report it files is `notice`. + +**Per-pass prompt substitutions.** `run_ephemeral_turn` takes a `system_substitutions` map. The two the system context resolves by itself (`__USER_PROFILE__`, `__SHARED_FOLDERS__`) describe the *session owner*, which for a pass about somebody else is the wrong person — so the review passes the **subject's** profile under its own `` key (rendered by the shared `loop_adapters::system::render_user_profile_section`). It goes in the system prompt rather than the trigger message because age, name and sex change what counts as worth reporting, and the model needs them before it reads a word of the transcript. + +**A locked user is skipped, and that is the normal case, not an error.** The pool is the unlock token (§9): a user who has not logged in since the last restart has no readable events, no session store — and no place to record the skip, since the only file that could hold it is the one we cannot open. Hence `system_agent_runs` has no `skipped` status: the skip is an INFO log line and nothing else. + +**`AgentScope::Instance` is the ownerless-work escape hatch, and there is exactly one user of it.** The shared memory store belongs to nobody, but a pass over it still has to run *somewhere*: an ownerless run would write its trace into `system.db`, which `GET /api/system-agents/runs` shows to nobody (scoped on the caller's own pool, by design), and its `notify()` would have no recipient. So `instance_pass` runs it as the **first active unlocked admin** (`users::list` order, so the choice is stable across passes), and the whole per-user surface keeps working unchanged. Cost: it needs an admin who has logged in since the restart. + +**The run log is theirs, not the admin's** (`db/system_agent_runs.rs`, owner table, no `user_id` column — the file is the owner). `GET /api/system-agents/runs` is scoped through `require_context` with **no admin override**: everyone, admin included, sees their own runs. `stats` is a JSON blob of the agent's own counters, never contents. + +**The configured security group is not applied verbatim.** `.security_group` is an instance-wide admin setting; handing it to a restricted member's run would give their background agent a tool set their role never granted. `system_agents::configured_run_context` puts it through `run_context::reconcile_group_for_user` — the same seam a persisted group takes — degrading to the role default when the role disallows it. With nothing configured the run still starts from `role_default_run_context`, never `None`, because `None` means the catch-all group, which is *wider*. + +### The conversation review + +`system_agents/conversation_review.rs` — nightly, one report per supervised subject, covering **every** conversation in the window rather than one report per session (the useful signal is often *across* conversations). The window is `[covered_through, now)` and due-ness is "the watermark stops before the most recent occurrence of `run_at_hour` local" (default 4am), which is also why downtime needs no catch-up mechanism: a machine off for three days finds a three-day-old watermark and covers it in one pass. `most_recent_occurrence` is generic over the timezone so it is testable without depending on where the box is, and resolves through the timezone (not UTC arithmetic) so a DST-skipped hour is handled. + +`chat_history::conversation_window` is the transcript query, and its four filters each exist because of a specific way the result would otherwise be wrong: `is_ephemeral = 0` (or a pass reads the transcript its *previous* pass was given and reports on itself), `depth = 0` (sub-agent frames are machine-to-machine), `is_synthetic = 0` (machinery-injected turns are not things the person said), `content <> ''` (an assistant row that was only a tool call). **Tool calls are absent by construction, not by filter** — they live in `chat_llm_tools` — so the review sees what was *said*, never what was *done*, and the prompt says so plainly because a model shown a gap narrates over it. Rendering is prose grouped by conversation, never JSON: a dialogue read as a dialogue is what models are best at, and nothing machine-readable comes back this way — the structured artefact is the report at the other end. + +### The memory lints + +`system_agents/memory_lint.rs` — one struct, two instances differing only by fields: `MemoryLintAgent::private` (`PerUser`, over `user-memory/` in the caller's pool) and `::shared` (`Instance`, over `shared-memory/` in the system pool — the same routing `classify_memory` gives the fs-tools). Prompts are two `AGENT.md`s sharing `agents/common/memory-lint.md`; the shared one additionally hunts **table-rule violations** and is told to report *which note and what kind of problem* without repeating the sensitive line, since restating it is the harm being flagged. + +**Read-only, enforced twice.** The prompt says report-never-repair, and `shared-memory/*` writes are already `@fs_write require` — so an agent that tried to fix something would raise an approval card from an unattended pass, which `run_ephemeral_turn` auto-denies. Read-only is not a convention here, it is the only thing that works. `has_work` is "the store is non-empty", so a member who never uses memory collects no weekly row and no weekly notification. + +**Interval units are per-agent**: event triage in minutes, the lints in days (`interval_from_config` takes the unit). Asking an admin to type `10080` for "weekly" would be a worse version of the same field. + +**The cadence is per user for exactly one agent, and the trait says so in two methods, not one.** Event triage fires on *inbound* events, so how often it has work is a property of the person — someone on a dozen mailing lists triggers it on nearly every tick from the same setting that leaves a quiet account idle for a day. So `SystemAgent` gained `interval_secs_for(user_id)` (what `is_due` measures against) beside the instance-wide `interval_secs`, both defaulting to the latter so every other agent implements nothing. The second method is the non-obvious half: `base_tick` sleeps for the shortest interval any enabled agent asks for, so an agent whose overrides can go *below* its instance value must also implement `shortest_interval_secs` — without it the wake-up never comes round often enough and the override works when it lengthens and silently does nothing when it shortens. Storage is the registry table `system_agent_user_settings(agent_id, user_id, interval_secs)` (accessor + `interval_for_user`/`shortest_interval_for` helpers in `system_agents/mod.rs`, both failing **open** onto the instance value): **a row is an override, its absence is inheritance** — no sentinel value, no row written at user creation, and clearing the field deletes the row. Registry rather than the user's own `user_config` for a reason that is not about scope: the writer is the **admin**, on `#users/{id}`, and a member's file is unreadable unless they happen to be logged in (§9) — a setting that could only be changed while its subject has a live session would not be a setting. Endpoints `GET/PUT /api/users/{id}/event-triage` (admin-gated, minutes on the wire, `null` = inherit), rendered as one section on that person's page next to the grants. **Nothing rides the bus**: the scheduler re-reads the interval every tick and due-ness is measured from the user's own last attempt, so a change lands on the next wake-up with no push and no subscriber — the `ConfigKeyUpdated` reschedule stays for the *instance* key only. Keyed by `agent_id` though only one agent uses it, because the alternative is a column per agent on `users` and "a fourth agent is a trait impl plus one registry line" would stop being true the moment its schedule needed a schema change. + +### Where the settings live + +`ConfigSet` gained `owner: Option` (core-api): `None` renders on the general Config page, `Some(agent_id)` is claimed by the surface that owns it. Placement is **data on the set**, not a filter that knows set names, so a new owned set lands in the right place without touching either page. `system_agents::registry()` and `::config_sets()` are the single enumeration of the agents — `registry_and_config_sets_agree` is the test that stops the scheduler's list and the settings surface from drifting. + +`/api/config` serves only owner-less sets and is now **admin-gated** (`caps::require_admin`), read *and* write: before this, both handlers ignored the caller entirely, so any authenticated session could read and change instance config — the sidebar hiding the page is presentation, not authorization. `GET /api/system-agents` lists the agents, with `config` resolved (via the shared `config::render_sets`) only for an admin and `Value::Null` for everyone else; writes still go through `PUT /api/config/{key}`, so the gate and the known-key check exist in one place. + +UI: `#system-agents` (`web/components/system-agents.js`, sidebar group `extensions`, **visible to everyone** — the run log is the caller's own). **One tab per agent, plus "All"**, each tab holding that agent's description, its settings (admin only) and its runs — the tab is the agent, not the kind of information, because "why did this do nothing last night?" is half a schedule question and half a log question. The settings form is `web/components/shared/config-form.js` (`ConfigFormController`), shared with `config-page.js` so an owned set renders identically wherever it is edited. It replaced a since-removed debug page (`#tic`, from when the triage agent was called TIC), which listed `chat_sessions WHERE source='tic'` and so inferred runs from leftover ephemeral sessions rather than recording them. + ## Multimodal attachments Uploads go through **one centralized seam** — `ChatHub::save_upload` (behind `ChatHubApi::save_upload`, backed by `skald_core::uploads::save_to_home`) — so every surface persists identically and no two callers can drift on placement (the class of bug where the agent was handed a path it couldn't reach). The seam writes into the **caller's container home** under `uploads/{session_id}/` (agent path `uploads/{session}/{name}`, the `UPLOADS_SUBDIR` const in `core-api/user_fs.rs`), collision-dedupes the name, and prefers the sniffed magic-byte MIME over the client claim. The **web** handler (`POST /api/{source}/uploads`) buffers each field with a 256 MiB cap then calls the seam; the **Telegram** plugin downloads bytes then calls the same seam via `handle.chat_hub().save_upload("telegram", …)`. Because the file lands in the home (bind-mounted at `/root`), it is reachable by the fs-tools, `execute_cmd`, and the file viewer (`GET /api/file`, per-user via `resolve_view_path`) — there is **no** `/data` static route anymore (removed: it was `require_auth`-only, not ownership-scoped, and also exposed internal server state under `data/`).

The child's result string becomes the parent tool call's result (completion lives in one place — the `run_agent_turn` tool-result match); then it terminates the child frame. There is no task-spawn / `WaitingChild` / resume cascade for the sync path. -- Max recursion depth: `MAX_AGENT_DEPTH = 5`. -- **Parallel batches:** when a single assistant response emits **≥2** sync sub-agent calls and *nothing else*, `run_agent_turn` fans them out concurrently via `handle_sub_agent_batch` (bounded by `max_parallel_subagents`, default `4`). Ordering is preserved by allocating every `chat_llm_tools` row up front in call order (the LLM reconstructs results by row id), then recording outcomes back in call order; only the middle dispatch is concurrent. Any other shape (a lone call, or a mix with regular tools) keeps the strictly sequential `handle_tool_call` loop — the two paths share the same lower-level seams. Siblings share the session's scratchpad blackboard (session-keyed): concurrent writes to the *same* key are last-writer-wins by design. -- **Restart recovery of a parallel batch** is intentionally lossy (single-user app): `resume_turn` first calls `reap_interrupted_parallel_batches`, which detects a batch by ≥2 active `chat_sessions_stack` frames at the same depth (impossible for a linear stack), fails their spawning tool calls and terminates the frames, then lets the normal linear cascade resume the parent. A lone interrupted sub-agent is untouched and still recovers via the cascade. -- Client resolution order: `args.client` → `meta.json client` → AUTO selection by scope/strength. -- **The parent's resolved client is NOT inherited.** Passing a concrete model name to `resolve()` bypasses strength/scope checks; sub-agents always auto-select unless overridden explicitly. -- `list_agents` is a plain tool; returns JSON of **task** agents only (excludes `chat`/`system` agents like the `assistant` entry agent). -- `resume_turn` (+ its cascade) is kept only for: app-restart recovery of an active child stack, async task result injection (`inject_async_result`), and the WS resume message — not for the normal sync dispatch. -- **The cascade runs each frame with ITS OWN agent's config, not the session root's.** `resume_turn` builds the root config from `self.agent_id`, but for any non-root frame (deepest seed + each parent it walks up) it derives a per-frame config via `build_recovery_frame_config` → `build_sub_agent_config` (keyed on `frame.agent_id`), so a resumed sub-agent runs with its own prompt/tools/client — not the root's (it would otherwise resume e.g. a `researcher` as the `assistant`). `build_sub_agent_config` is the **single** source of a sub-agent's config, shared by live `dispatch_sub_agent` and this recovery path so they can't drift; the per-dispatch `client` override isn't persisted, so recovery re-resolves the model from the frame's agent meta. +## The LLM loop (`agent-loop`) + +The loop is a **standalone crate** (`crates/agent-loop/`) that knows nothing about Skald: it owns control flow (rounds, model fallback, tool fan-out, recording), the projection of history into wire messages, sub-agent delegation, restart recovery and compaction. Skald supplies content through the traits in `crates/skald-core/src/loop_adapters/`. Nothing in `session/handler/` shapes a `Value` anymore — there is exactly **one** projection in the workspace. + +**One `LoopManager` per user** (`UserLoopRuntime`, `loop_adapters/runtime.rs`, blueprint D12), built by `ChatSessionManager`: it owns the event bus, the live-loop registry (which conversations are running, `/stop`, recovery, shutdown), the store, the approval gate, the hooks, the agent catalog and the delegate tool. A turn contributes only what is its own — the agent's prompt, its tool set, its model pin — via `turn_params`. + +**Per-turn state rides the `Extensions` type-map** (`loop_adapters/scope.rs::TurnScope`): the gate and the catalog live as long as the user, so they cannot capture a session id or a permission group — they read the turn's scope from the call's extensions. **A call with no scope is denied**, never run with permissive defaults. + +Three entry points, all in `session/handler/kernel_turn.rs`: + +| entry | when | what it does | +| ---- | ---- | ---- | +| `run_kernel_turn` | a user message | repairs a dangling call from a crashed turn, then `manager.start_turn` | +| `recover_turn` | WS connect, async result delivery, background wake-up | `Recovery::run` — no new message, continue what was interrupted | +| `resolve_pending_call` | an approval answered after a restart | run the call with the gate skipped, then continue | + +The event **translator** (`loop_adapters/translate.rs`) is the ONE bus subscriber turning `LoopEvent`s into the session's `ServerEvent`s; byte-parity with the pre-kernel event sequence is its contract. + +### Sub-agents + +- A sub-agent is a **tool**, not an interception: `DelegateTool` (registered under the legacy names `execute_task` / `execute_subtask`, D11, each keeping its exact legacy schema) opens a child frame and runs a normal loop in it. The parent simply awaits a slow tool call. Max depth `MAX_AGENT_DEPTH = 5`. +- **Parallel batches are the kernel's generic fan-out**: a round whose calls are all `concurrency_safe` (a sync delegate is) runs concurrently, bounded by `max_parallel_calls`. The ordering invariant is unchanged — ids allocated in call order (phase 1) → concurrent execution (phase 2) → recording in call order (phase 3) — so the model reconstructs results by id. Any mixed batch stays sequential. Siblings share the session scratchpad; concurrent writes to the same key are last-writer-wins by design. +- `mode: "async"` submits a durable `scheduled_jobs` row through `loop_adapters/async_task.rs::CronExecutor` and returns a receipt immediately; when the job finishes, `DurableSink` writes the result into the parent conversation (synthetic assistant + a completed `task_completed` call) and resumes it. `mode: "cron"` is scheduling, not delegation, and stays on the cron interface tool. +- **An async task ends in the conversation that started it, whatever happened to it** — and `cron::run_job` is shaped so it cannot do otherwise: one `JobOutcome` classification, then *one* `match job.kind` delivery site for every ending. It used to branch on `Ok`/`Err` first and route by kind only inside `Ok`, so a failure or a kill went out as a "Cron job … failed" notification to the **home** source (`/sethome`) while the parent sat waiting for a `task_completed` that never came — the wrong chat *and* a wedged conversation. The sink has a single channel by design: to the model, "it broke" is a result like any other and must not be overlookable, so the failure is delivered as prose (with whatever partial output the run produced). A cron job has no parent conversation and keeps the home notification — the future plan is to let its creator name a destination. Cancellation is a third outcome, not a flavour of failure: `job_runs.status` always had `'cancelled'` in its CHECK and nothing wrote it, and the classifier keys on the **typed** `session::handler::TurnCancelled` error, never on the message text. +- **The chat shows what it started.** `ServerEvent::TaskUpdate` announces an async task's state to the source of its parent conversation only (a cron job belongs to nobody's chat), and `GET /api/{source}/tasks` (`db::scheduled_jobs::list_for_parent_session`) answers the same question at load time — running tasks plus failures from the last 30 minutes, because the event is a broadcast with no replay and a browser reload would otherwise empty a chat that still has work under it. Successes are absent from that query on purpose: a finished task's result is already a message in the conversation. The strip itself is `web/components/shared/agent-tasks.js` (`renderTaskStrip`), rendered above the composer on desktop and mobile from state owned by `ChatSession`; the drill-in is `#session/{id}`, gated on `_canOpenTaskSession` because the mobile shell routes a fixed set of sections and would silently swallow that hash. +- A child's model is **never inherited** from the parent: passing a concrete name would bypass AUTO selection, so sub-agents auto-select unless explicitly overridden (`args.client` → `meta.json client` → AUTO by strength). +- `list_agents` returns **task** agents only (never `chat`/`system` ones like the entry agent). + +### Restart recovery (`agent_loop::recovery`) + +A crash loses RAM (the approval oneshot, the cancellation token), never truth: every state transition is a store write. So recovery does not have a mode of its own — it makes the history well-formed and then runs a **normal loop** on it: + +1. **Reap** an interrupted parallel batch (≥2 active frames at one depth is impossible for a linear stack): fail their spawning calls, close the frames. Deliberately lossy. +2. **Resolve** the deepest frame's non-terminal calls. A `Running` one is re-gated and re-executed **unless the tool says otherwise** — `execute_cmd` declares `RestartHint::MarkInterrupted` (D7), because a command may already have had its effect. An `AwaitingHuman` one is re-asked (the card reappears). +3. **Un-wedge**: a child that finished but whose result never reached its parent propagates without calling the model again. +4. **Cascade** to the root, resolving each parent call with its child's result — every frame running as **its own** agent, from the catalog, never the root's (B3). + +`Cancelled` and `Rejected` are terminal and are never re-executed. Anti-double-driving goes through the manager's registry (a recovery claims the conversation like a live turn), not a host-side flag. ## Cancellation (stop) -- Each turn has a `CancellationToken` (`tokio_util`). `handle_message` mints a fresh one per user message and stores it in `current_cancel`; `resume_turn` mints one per resume. A **clone is threaded by value** through the whole (recursive) call tree — never re-read from the field mid-turn — so a `/stop` is **sticky** across sub-agent recursion. -- `cancel()` cancels the stored token. It is checked at each round boundary and before each tool call, wrapped around the in-flight LLM call (`tokio::select!`, aborting the request), and wrapped around `execute_cmd` (drops the future → `kill_on_drop` kills the shell process). Parent and child share the token, so a cancelled child stops the parent by construction. +- The turn's `CancellationToken` is minted by `LoopManager::start_turn` and **cloned by value** down the whole call tree; a delegate passes `ctx.cancel.child_token()`. It is never re-read from a field mid-turn, which is what makes `/stop` **sticky** across sub-agent recursion. +- `ChatSessionHandler::cancel()` → `manager.cancel(&conversation)`. The token is checked at each round boundary and before each tool call, wrapped around the in-flight LLM call (`tokio::select!`, aborting the request), and around `execute_cmd` (dropping the future → `kill_on_drop`). Parent and child share the tree, so a cancelled child stops the parent by construction. + +## Compaction + +`agent_loop::compaction` owns the mechanics: split point (never between an assistant turn and its tool results), transcript, prompt (`SUMMARY_PREFIX` / preamble / template live there now), the single no-tools model call, the saved summary row. `skald-core/src/compactor.rs` owns the **policy**: the token threshold, the ephemeral guard, which model summarises (`compaction_model` from Settings, else AUTO by `compaction.strength`), and publishing `CompactionEvent` on the chat bus. The DTL re-anchor is the `on_compacted` hook (`loop_adapters/hooks.rs::DtlReanchorHook`). The next turn needs nothing: the assembler reads the latest summary from the store. + +### Context size: both automatic guards are off by default + +Nothing shrinks a conversation unless a human asks. `llm.max_history_messages` and `llm.compaction.threshold_tokens` are both `Option`, both **unset** in `default.config.yaml`, and the only remaining reducer is the user typing `/compact`. The reason is the **prompt cache**: every provider that caches (Anthropic breakpoints, OpenAI automatic prefix caching) keys on the longest common *prefix*, so anything that rewrites history mid-conversation costs a full miss on the next request. + +The two guards are not equally bad at that, and the difference is why one is merely off and the other is close to a trap. `max_history_messages` is a **sliding tail window** (`agent_loop::projection::window` — `drain(..len - max)`): past the cap it drops from the head on *every* turn, so it is a cache miss *per request*, forever, and it drops messages with **no summary standing in for them** — silent amnesia. Compaction rewrites the prefix **once per compaction** and leaves a summary behind. So the previous default — window on, compaction off — was the worse of the two in both dimensions, and the window's own doc-comment already said the two were mutually exclusive. + +Three consequences worth not re-deriving: + +- **The compactor is built unconditionally**, in both `bundles.rs` and `user_context.rs`. It used to be `Option>`, keyed on the config section existing — which meant that commenting out `compaction:` also silently disabled **manual** `/compact` (`force_compact` returned `Ok(false)` and the chat answered "compaction disabled"). Manual compaction is a command a user types; it must not depend on an admin having filled in a token threshold. `try_compact` early-returns on `threshold_tokens: None`; `force_compact` deliberately does not consult it — the human *is* the trigger. +- **The projection yields to the *automatic* pass, not to the compactor's existence**: `LoopConfig.auto_compaction_enabled` (`= ContextCompactor::auto_enabled()`), so a configured message cap is not silently voided by the mere availability of `/compact`. Expressed as `max_history_messages.filter(|_| !auto_compaction_enabled)` in `projection_cfg.rs`. +- **`CompactionConfig`'s `Default` is hand-written**, same trap as `RoleAttrs`: a derived one gives `keep_recent: 0`, which would compact away every recent message on any box omitting the section — now the shipped default. + +The future automatic pass should trigger off the **resolved model's own context window**, not a hand-tuned `threshold_tokens` that has no idea which model is answering. + +### The system prefix is frozen per conversation + +Same economics, other end of the request. `AgentSystemContext::system_context` is called **once per round**, and it reassembled `base` from disk and SQLite every time — so an agent writing `user-memory/index.md` in round 3 made round 4, seconds later and with the cache certainly warm, a full miss. Since `base` is the head of every provider's cache key, that is the most expensive string in the request to touch. `loop_adapters/prefix_cache.rs::PrefixCache` builds it once per `(conversation, agent)` — the agent is in the key because a sub-agent shares its parent's conversation but has a prompt of its own — and holds it on `UserLoopRuntime`, so it outlives the turn. + +The refresh rule is the only one that is free: **rebuild once the conversation has been idle longer than a provider's cache could survive** (`PREFIX_TTL`, 20 min). The clock is therefore *idle time of this conversation*, not time since a file changed, and reading restarts it — every `get` is a request about to go out. The asymmetry that sets the constant: below a provider's window you pay misses that buy nothing, above it you only pay freshness. + +**Writes are deliberately not reacted to, and there is no bus variant for this.** When the agent itself edits an injected file the content is already in the context — its tool call and result sit two messages downstream — so refreshing would repeat what the model just said. A write from *elsewhere* (the same user's Telegram session, a cron job, another member editing `shared-memory/`) is genuinely invisible until the TTL: that is the case where an immediate rebuild costs the most, since a conversation that would notice is by definition a warm one, and the cheaper freshness path already exists — the agent can `read_file`, and a tool result *appends*, which invalidates nothing. The injection header says so in words. Cross-user invalidation of a *file* write would need a `SystemEventBus` variant plus a subscriber per user (the writer lives in a different `UserContext`); it is future work, and this type's key is the seam for it. Note `base` is frozen **whole**: freezing the memory files while letting `__USER_PROFILE__` move would invalidate just as much. The cost is that an `AGENT.md` edit lands at the next rebuild rather than the next round. + +**What *is* invalidated eagerly: the two generated lists, because a stale one makes the model deny a tool it has.** The TTL is right for injected content the agent can re-read on demand and wrong for an inventory — a model that reads "no such connector" in the `## MCP servers` table does not go looking, it answers the question. So `Skald::invalidate_prompt_prefix` (the skills door, called straight from `skill_register`/`skill_delete`) has two MCP siblings, both looping the `all_live()` they already had: `refresh_global_mcp_access` — the admin enabling or re-granting a global connector, where refreshing the access snapshot alone fixed what `mcp.tools()` *offers* while leaving the table describing the world before it — and `refresh_connector_after_reinstall`, where a reinstall's new `llm_short_description` reached the runtime but not the prompt. **Order is load-bearing and opposite to the intuition**: `render_mcp_list` renders the live runtime's in-RAM state, not the DB, so the invalidation goes **last**, after the snapshot refresh and after the servers restart — rebuild the prefix first and it is repopulated from the very descriptions being replaced, with nothing left to invalidate it again. In the reinstall that means waiting out a global dependency install that can take minutes; correct anyway, since those users were already reading a stale table and an early rebuild would only freeze the stale one in place. The price is a provider cache miss on the next turn of every open conversation of every live user — cross-user by nature, since one admin is changing something for other people, and there is no cheaper direct path the way there is for a user editing their own memory. It buys back the failure the skills doc-comment already describes word for word. ## Approval gate -The rule engine `ApprovalManager::check` returns `Allow`/`Deny`/`Require` per tool call (default rules seeded on first boot; the catch-all `* require @999999` gates anything not explicitly allowed — e.g. `execute_cmd`, `execute_task`, writes outside whitelisted paths). A `Require` registers a `oneshot` in the in-memory `pending` map keyed by `request_id` and emits an approval event over WS. +The rule engine `ApprovalManager::check` returns `Allow`/`Deny`/`Require` per tool call (default rules seeded on first boot; the catch-all `* require @999999` gates anything not explicitly allowed — e.g. `execute_cmd`, `execute_task`, writes outside whitelisted paths). It is wired to the loop as `loop_adapters/gate.rs::ApprovalGate` (`agent_loop::gate::Gate`).

Live pending cards fire the `oneshot`; post-restart a simple tool runs directly on the owning session via `ChatSessionHandler::execute_tool`, which now goes through the **same canonical path as the live loop** — `build_execution` (owner pool + per-user container `ToolContext`) driven by `drive_execution` — so a resolved `write_file`/`execute_cmd` acts on the user's workspace/container, never the server cwd/host (was a §6 escape; sub-agent tools are still handled by their own branch earlier in `resolve_tool`). +Resolution is **source-agnostic**: the WS + Inbox paths resolve by `request_id`; the inline chat card resolves by the durable `tool_call_id` via `POST /api/tools/:tool_call_id/resolve` (`resolve_tool` in `src/frontend/api/sessions.rs`), which derives the owning session from the tool call's own stack row — never a hardcoded source.

The source-taking methods survive as one-line resolvers (`send_message` → `send_message_to_session`, and `_for_session` twins for context/cost/compact/mcp/model/cancel/resume/upload), so Telegram, mobile and cron are untouched. Cost of the rekey: queues now grow with conversations-talked-to-since-boot rather than with the four-or-five sources, so a reset **retires** the queue it replaces (`retire_inbox` → `ConversationInbox::close`, consumer breaks) instead of leaving a parked task forever. + +**Events are filtered per conversation** (`ge.session_id == Some(session_id)`), which is why anything a chat must see has to carry a session id — an untagged `GlobalEvent` now reaches nobody. Two emitters had to be fixed for exactly that: `show_file_to_user`'s `OpenFile` (the tool takes a `session_id` from `handler.session_id` via the interface-tools builder) and `revalidate_security_groups`, which now returns `(session_id, source, group)`. The inbox lifecycle events (`Approval*`/`Clarification*`/`Elicitation*`) stay the deliberate exception and go to every connection, since they carry ids only and drive the sidebar badge. A **primary** WS connection additionally follows `NewSession` for its source — re-binding `session_id` and its handler mid-loop — so a second window doesn't keep talking to a conversation another window just reset; a session-addressed one ignores it, having been pinned on purpose. + +**The tab bar is server-side state; the selection is not.** Which conversations the copilot shows survives a reload through `chat_sessions.is_open` (owner table, additive via `ensure_column`) — `GET /api/sessions/open` restores them (computing `primary` per row, since only `sources` knows), `PUT /api/sessions/{id}/open` opens/closes one, `PUT /api/sessions/{id}/title` renames one (`title` predated all this and was dead; an empty title stores `NULL`, so the rename box is also the undo). It is deliberately *not* localStorage: that store is per-origin, so on a shared laptop one member's tabs would greet the next, and in the user's own encrypted file the set follows them across devices instead. **Which** tab is selected stays in `sessionStorage` (`copilot-active-tab`), because that one is per browser window — a shared value would have two windows fighting over it and turn every tab click into a write. Three consequences that are easy to get wrong: (a) `is_open` defaults to **0** and `chat_sessions::create` never sets it — every `/new` leaves its predecessor behind and every system-agent pass mints a row, so `DEFAULT 1` would restore a bar full of conversations nobody opened; only the copilot writes the column. (b) The General tab is never stored — it exists because the copilot exists. (c) A reset **moves** the flag: `provision_session(reset)` mints a new row, so `POST /api/sessions` returns the new id and the `new_session` event carries it, and `_bindTabSession` closes the old row as it opens the new one — leaving both would restore the source twice and let a later close clear the stale one. Restoring the selection happens *before* `super.connectedCallback()` (sessionStorage is synchronous) so the first paint doesn't fetch General and throw it away; the set arrives over the network and reconciles after, awaiting the base's initial connection so it never opens a second WS. + **Theme** (`web/css/variables.css`): warm "paper" palette (terracotta accent, light by default, warm-charcoal dark), generous radius (`--radius-sm/md/lg`), 16px-base chat type, WCAG-fixed contrasts, global `:focus-visible` ring and `prefers-reduced-motion` support. Everything consumes CSS variables — never hardcode a hex in a component stylesheet. -**i18n** (`web/lib/i18n.js` + `web/i18n/{en,it,fr}.js`): `t(key)` helper, `I18nMixin` re-renders on `locale-changed`. Resolution order: user preference (`users.locale`, editable on the profile page) → instance default (registry config key `ui_locale`, editable by the admin in Settings — declared in `skald_core::i18n::config_set`) → English. **Server-side, never re-implement that chain**: `skald_core::i18n::resolve_locale(pool, user_locale)` is the one function (with `default_locale(pool)` and `language_name(locale)` for prompt rendering); they read through `db::config` because the bus only matters for writes and callers like `MessageBuilder` hold pools, not the manager. Pre-auth screens use the localStorage cache. Default locale is English. First-run setup asks the language in both shells — the console wizard writes `ui_locale` via `skald_core::i18n::set_default_locale` (no system bus exists there), the web setup page sends `locale` to `POST /api/setup/user`, which writes it through `GlobalConfigManager::set`. Supported locales are centralized in `skald_core::i18n::SUPPORTED_LOCALES` and enforced server-side on every write. Translated so far: chrome (sidebar/topbar), chat + approval cards, login/setup, profile, inbox; deep admin pages are still English (fallback is automatic per-key). Copy is the only place domain words may appear (§0.1). +**i18n** (`web/lib/i18n.js` + `web/i18n/{en,it,fr}.js`): `t(key)` helper, `I18nMixin` re-renders on `locale-changed`.

Copy is the only place domain words may appear (§0.1). **Plugin & backend i18n** — two seams, both keyed the same way. A plugin **page fragment** (served from its own router) localizes client-side: it ships a `web/i18n.js` module (`export default { en, it, fr }`, keys namespaced `plugin..`) and calls `addStrings(dicts)` (in `web/lib/i18n.js`) once at module load to merge into the host's shared `DICTS`, then uses the same `t()`/`I18nMixin` as the app (the fragment imports them from the absolute `/lib/i18n.js` — the *same* module instance the host uses, so `t()` and `locale-changed` are shared; no endpoint, no per-locale fetch — all locales ride in the fragment, so a language switch is instant). Mobile-connector is the reference: `common.js` registers the dict + re-exports `t`, and `MobileBase extends I18nMixin(LitElement)`. **Backend-generated strings** (a plugin's HTTP error/response text, notifications) go through `core_api::i18n`: a plugin declares `Plugin::i18n() -> Vec` (mobile-connector loads them from embedded `i18n/{en,it,fr}.json` via `include_str!`), the `PluginManager` merges every plugin's bundles once at boot into an `I18nCatalog` (`skald_core::i18n`) and injects it as `PluginContext.i18n: Arc`. At request time the handler resolves the caller (`Caller.user_id` from the auth layer) and calls `i18n.for_user(user_id, key, args).await` — which reads `users.locale`, runs it through the same `resolve_locale` chain, and renders `locale → en → key` with `{name}` placeholders. The frontend surfaces these already-translated: `jf()` throws the server's response text verbatim. Front and back keep **separate** tables (UI labels ≠ error strings; overlap is minimal) but share the `plugin..` namespace convention. The mechanism is general (any plugin, and eventually the core, registers the same way); only mobile-connector uses it so far. **Role-driven interface** (§0.1 — data, not enums): `roles.attrs` JSON may carry `"ui_mode": "simple"`. `/api/auth/me` resolves it via `RoleAttrs` (`admin` is always `full`) and the sidebar renders chat + inbox only for simple-mode members; the role editor exposes it as an "Interface" select. Hiding links is never access control — routes stay capability-gated server-side. `MeResponse` also carries `locale`, `default_locale` and `encrypted`. -**Security-group picker (per-session, runtime, role-gated).** A **security-group** is a *permission bundle only* — a `tool_permission_groups` id, driving tool visibility/approval — **not** a "mode" (no system-context injection; the `RunContext.system_prompt` substrate exists but is unused by the picker). The role carries the user's **allowed set** (default `permission_group` + `attrs.permission_groups`, §0.1); a new non-project session inherits the role's default group (`sessions.rs::create` → `role_default_run_context`). The chat surface switches it **at runtime like the model pill**: `copilot.js` renders a shield pill (hidden when ≤1 group) fed by `GET /api/my/security-groups` (the caller's role set, joined with group names; `admin` → all); selecting one sends the WS control message `{type:"select_security_group", group}` (`chat-session.js::_selectGroup`, twin of `select_client`). The server (`ws.rs::handle_select_security_group_msg`) validates against the role, persists it on `chat_sessions.run_context`, updates the live handler, and **broadcasts `ServerEvent::SecurityGroupSelected`** so every open tab re-syncs (the initial state is sent on WS connect). **Enforcement is server-side** via the shared `run_context::validate_run_context_for_role` (used by both the WS path and the REST `set_session_run_context`): a non-admin may only pick a group in its role's effective set (else 403), and **every other `RunContext` field** (`system_prompt`, `allow_fs_writes`/`allow_fs_reads`, `working_directory`) is **discarded** — closing an fs-escalation hole; `admin` passes through unchanged. The role editor (`roles-page.js`) sets the default group + an allowed-groups checklist (→ `attrs.permission_groups`) + a **default-assistant** select (→ `attrs.chat_agent`) fed by `GET /api/agents` filtered to `type:chat` minus `project-coordinator` (source-driven); the same exclusion is enforced server-side in the roles API (`validate_chat_agent`). +**Security-group picker (per-session, runtime, role-gated).** A **security-group** is a *permission bundle only* — a `tool_permission_groups` id, driving tool visibility/approval — **not** a "mode" (no system-context injection; the `RunContext.system_prompt` substrate exists but is unused by the picker).

The fix is a second, narrower seam: `run_context::reconcile_group_for_user`, run by `ChatSessionManager::get_or_create_handler` on **every** handler build, which treats the stored group as *advisory* and degrades it when the owner's current role no longer allows it. Three properties are load-bearing: (a) it degrades to the **role's default group** (`role_default_group`, the same seam `sessions.rs` uses for a new session, so start-group and fallback-group cannot drift) — **never to `None`**, because a missing group means the catch-all `default`, whose rules are the fallback tier under every other group, so clearing *widens*; (b) it touches **only** `security_group`, unlike the selection path, so a project session's server-built `project_root`/`system_prompt` survive a permissions edit; (c) on uncertainty (unknown user, unreadable role, DB error) it leaves the stored group alone — guessing could only widen. The liveness half is `Skald::revalidate_security_groups_for_{user,role}`, called **synchronously** from the roles API (`update`) and the users API (role reassignment), which reconciles already-open handlers, persists, and emits `SecurityGroupSelected` so the pill re-syncs. Same rule as revocation: authorization is pushed, never left to the bus. + +The role editor (`roles-page.js`) sets the default group + an allowed-groups checklist (→ `attrs.permission_groups`) + a **default-assistant** select (→ `attrs.chat_agent`) fed by `GET /api/agents` filtered to `type:chat` minus `project-coordinator` (source-driven); the same exclusion is enforced server-side in the roles API (`validate_chat_agent`). | File | Element | Notes | | ---- | ------- | ----- | @@ -315,14 +503,16 @@ All extend `LightElement` from `web/lib/base.js` (Lit). `ChatSession` (`web/lib/ | `agent-inbox.js` | `` | Pending approvals + clarifications from background sessions | | `approval-rules.js` | `` | Approval rule management | | `cron-jobs.js` | `` | Scheduled job management | -| `connectors.js` | `` | MCP Connectors list (one row per connector): user activate/deactivate + granted globals; admin gets a **Sign-in providers** modal (OAuth client creds) + Catalog/Marketplace nav (§7/§14/§15) | -| `plugins-page.js` | `` | `#plugins` — user half: granted plugins + schema-driven per-user config form | -| `plugin-catalog.js` | `` | `#plugin-catalog` — admin status board: one card per plugin (enable toggle + health dot + Configure → `#plugin-detail`) | -| `plugin-detail.js` | `` | `#plugin-detail?id=` — one plugin's admin page: instance-config form (`config_schema`) + per-user access checklist (plugin twin of `connector-detail.js`) | +| `connectors.js` | `` | MCP Connectors row list (one row per connector): user activate/deactivate + granted globals; admin also gets the **Add connector** dropdown (Marketplace / manual form at `#connectors/new`), per-row removal from the catalog, and the **Sign-in providers** modal (§7/§14/§15) | +| `plugin-catalog.js` | `` | `#plugins` — admin status board: one card per plugin (enable toggle + health dot + Configure → `#plugin-detail`) | +| `plugin-detail.js` | `` | `#plugin-detail?id=` — one plugin's admin page: instance-config form (`config_schema`) + a **read-only** roster of who holds it, linking to `#users/{id}` (plugin twin of `connector-detail.js`) | +| `users-page.js` | `` | `#users` list + `#users/{id}` one user's page: Profile, **Connectors**, **Plugins**, Security.

Persist it **inside the + connector's own directory** (e.g. `./auth/` next to the entry file). That folder + lives under the bind-mounted home, so it survives container recreates and + connector updates. Never store it under a shared/global path. + +Skald resolves `auth.type: "qr"` the same way whether it appears in the index +entry or the manifest. + +--- + +## 5. Dependencies (node & python) — how they get installed + +**Do not ship `node_modules/` or vendored wheels.** Declare deps as a standard +manifest **file** and Skald installs them inside the container: + +- **node:** ship a `package.json` with a `dependencies` map. Skald runs + `npm ci --omit=dev` (falling back to `npm install --omit=dev`) in the connector + dir. `node_modules/` resolves automatically beside the entry file. +- **python:** ship a `requirements.txt`. Skald installs it with + `pip install --target .pydeps` and puts `.pydeps` on the server's `PYTHONPATH`. + +This runs at activation **and** on every startup, guarded by a **content hash** of +the connector's source files: + +- first activation / a brand-new container → full install, +- a connector **update** (any shipped file changed) → re-copy + re-install, +- unchanged → skipped in microseconds. + +So you never write install steps into the manifest — just ship the dep file, list +it in the index with its SHA-256, and set `requires: ["NODE"]` / `["PYTHON"]` as a +human hint. Pin versions in `package.json` / `requirements.txt` for reproducible +installs. Keep the dep tree lean (containers are slim; avoid native-heavy +packages where a pure alternative exists — e.g. Baileys instead of a browser). + +--- + +## 6. Verify-before-save (optional but recommended) + +Ship a `verify.py` / verify snippet and reference it: + +```jsonc +"verify": { "command": "python3 verify.py", "timeout_secs": 15 } +``` + +It runs with the collected env/secret injected and must print **one JSON object** +on stdout: `{"ok": bool, "message": string, "details"?: object}`, exit 0 on +success. Used for `api_key`/`none` connectors to test creds before activating. +(A `qr` connector needs no verify — its `login_status` is the live check.) + +--- + +## 7. Versioning & updates + +Three fields, in **both** the index entry and the `connector.json`, kept identical: + +| field | type | role | +| --- | --- | --- | +| `version` | **integer** | monotonic build number, **per connector** — the machine comparison key | +| `version_string` | string (semver) | display only | +| `version_release_date` | ISO date `YYYY-MM-DD` | display only | + +- `version` is a **number, not a string** (`1`, not `"1"` or `"2.0.1"`). Start at + `1` for the first release under this scheme; **`+1` on every change** to any + shipped file **or to any manifest metadata** (description, icons, `version_string`). + Never reuse or decrement. +- Skald stores the installed `version` and compares it to the feed's: a strictly + greater feed `version` shows **"update available"** in the marketplace, and the + Install button becomes **Update**. Clicking it re-downloads the files and rewrites + the catalog row. +- **The integer is the *only* "is there an update?" signal** — it is compared + strictly (`feed > installed`). `version_string` (semver), icons and + `llm_short_description` are **never** compared, so a change to any of them that + does not also bump the integer is **invisible**: no "update available" badge + appears. This is the common trap — a "content-only" edit (e.g. a better + `llm_short_description`) that forgets the integer. +- **Two propagation paths, do not conflate them:** + - *Per-user code + deps* (the scripts, `package.json`/`requirements.txt`) reconcile + on a **content-hash** of the source files (§5), so new code lands at each user's + next login even without a reinstall. + - *Catalog metadata* (`llm_short_description` → the model's prompt, icons, friendly + name) is **not** in that hash — it lives in the catalog row and is rewritten only + by an explicit **reinstall/Update**. On reinstall Skald re-pulls the current feed + (never the browse cache) and pushes the new description live: enabled global + servers restart with it, and every logged-in user who activated the connector has + it restarted with the fresh `llm_short_description` — no re-login needed. +- So: to ship a new `llm_short_description`, **bump the integer** (so the admin sees + "update available") and the admin clicks **Update**. Nothing auto-propagates a + description change. +- `version_string` and `version_release_date` are display metadata only — never + compared. (Migration note: replace any legacy string `"version": "2.0.1"` with + the integer `version` + `version_string`.) + +--- + +## 8. Checklist for a new connector + +1.

Deliberately *not* on enable/disable: re-enabling a plugin must not resurrect a +//! grant the admin took away, so the trigger is the row's birth, not its flag. +//! +//! ## Who counts as an auto-grant user +//! +//!

System agents — the background agents the instance runs on a user's behalf. +//! +//! A system agent runs without being asked.

Pinning overrides the strength choice for that conversation only. + +## Custom agents (admin) + +Agents are data, not code — an admin can add a new one by creating a folder on the server: + +- `agents//meta.json` — the name, description, type (`chat`, `task` or `system`), strength, and optionally an icon file. +- `agents//AGENT.md` — the system prompt (the `name` given in `meta.json` is what users will see; the folder name is the internal id). + +No restart and no rebuild: the app discovers the new agent and picks up prompt edits on the next use.

That is *in addition to* whatever you say — it is how the agent "remembers" between conversations. The Project Coordinator additionally reads the project's own `SKALD.md` when one exists, so it arrives already knowing the project. See [memory.md](memory.md). +- **The system agents are invisible on purpose.** They run on a schedule, not in a conversation, and they never talk to you — they notify you when something needs attention, and their work and settings live on the System agents page (`#system-agents`). See [system-agents.md](system-agents.md). +- **Prompts are not secrets.** Nothing on the Agents page is hidden from the user who can see it — if someone asks "what is the assistant told to do?", the answer is "read it on the Agents page". +- **Agents cannot change themselves.** An agent's prompt is a file on the server; the agent cannot edit it, and a user cannot make an agent "become" another agent by asking.

The review takes the whole stretch at once, so a subject that came up twice in two different places is something it can notice — reviewing each conversation separately would lose exactly that. +- **It reads what was *said*, not what was *done*.** Messages only. If the assistant ran a search, opened a file or used a connector, none of that is visible to the review — not the action, not the result. It is told to say so rather than guess. +- **It has no tools at all.** No filesystem, no memory, no connectors, no notifications. It reads the transcript it is handed and writes prose. It cannot act on anything it finds, and it cannot look anything up. +- **Nobody is reviewed unless a link says so.** No supervision link, no review — being a child, or a member, or anything else is not what triggers it. +- **The person being reviewed does not see the report.** It is stored for their supervisors. What they *should* know — and this is a matter for the household, not the software — is that their account is supervised at all. +- **A quiet report is the normal one.** The agent is told to report what a careful adult would want to know and could act on: distress, someone pressuring or approaching them, a risk to their safety, money, a pattern repeating across days. It is told *not* to report swearing, sulking, secrecy, embarrassment, awkward questions asked out of curiosity, or homework they wanted done for them. Most nights it should conclude there is nothing to report, and that is the system working — a review that passed on everything would be read once and ignored afterwards. + +The report is kept where the supervisors can read it rather than in the reviewed person's own space, and it names its window, so two reports never cover the same evening twice. + +## Why a run can be missing + +Users are handled one at a time, and a user with an **encrypted** space is **skipped** if they have not logged in since the server last restarted. + +This is not a fault, it is how the encryption works: their data is unreadable until they log in and their password unlocks it.

The same applies to the shared memory lint: it needs an admin who is available — which for an encrypted admin means logged in since the restart. + +Schedules are counted **per person from their own last run**, and they survive a restart — so a weekly pass stays weekly even on a machine that gets rebooted every few days. + +The conversation review has its own version of both rules, because it is about one person but runs for another: + +- The **supervised person does not need to be logged in** — provided their space is not encrypted, which is the normal setup for an account somebody else looks after. Without that, nothing could ever run at four in the morning. A supervised person who *has* an encrypted space is reviewed only while they are logged in, and there is no way around that: no password, no key, no reading it. +- **At least one of their supervisors must be logged in**, because the review has to run somewhere. If none is, the review waits, and the next one covers the whole stretch that was missed instead of losing it. +- If the machine was off at the scheduled hour, the review runs at the next start and covers everything since the last one — three days off means one report covering three days, not three missing reports. + +## The System agents page + +Sidebar → **System agents**.

The shared memory lint is the interesting case: pressed by a member it reads the same shared store the admin's nightly pass reads, and the report simply goes to the member who asked instead of the admin. +- **"Nothing to look at right now"** is a normal answer and arrives straight away — an empty memory store or an empty event queue starts no run at all, exactly like a scheduled pass that finds nothing. +- The pass then runs in the background: the row appears in the log below as *running*, and the notification arrives when it is done.

The schedule is a question of *when*, which the button answers; enabled is a question of *whether*, which stays the admin's. + +The conversation review has no button: it is about somebody else and picks its own subjects, so "run it for me" would not mean anything. + +**The run history is personal.** Each run is written into that user's own encrypted database, so every user — the admin included — sees their own runs and nobody else's. There is no instance-wide view. + +## What the admin can change + +Each agent's tab carries the same three settings, visible only to an admin: + +- **Enabled** — turns that agent on or off for the whole instance, for everyone. +- **Interval** — how long between passes for each person. Event triage is in minutes, the lints in days. The conversation review has **Run at (hour)** instead: it runs once a day, after that hour, local time — 4am by default, so the report is waiting in the morning. + For event triage this is a **default**, not a rule: see below. +- **Security group** — which tools the agent may use during a run. It is re-checked against each user's own role: if their role does not allow that group, their run uses their role's default group instead. Nobody's background agent gets more access than their role would give them. (The conversation review ignores this in practice: it is given no tools whatsoever, so there is nothing for a group to permit.) + +For the first three there is no per-user on/off switch: if the agent is enabled, it runs for everyone who has logged in. The conversation review is the opposite — it runs for **nobody** until an admin creates a supervision link, and that link is what turns it on for one person. + +### Event triage: a different interval for one person + +Event triage is the one agent whose right cadence depends on **who** it is running for, because it fires on things arriving from outside. Somebody on a dozen mailing lists has something waiting on nearly every pass; somebody who gets three messages a week has something waiting almost never. One number for the whole household serves one of them badly. + +So that interval can be set per person: sidebar → **Users** → click the person → the **Event triage** section. + +- **Leave the field empty and they follow the instance setting**, whatever it is now and whatever it becomes later. That is the normal state, and nobody has a row until an admin types one. +- **Type a number of minutes and it applies to that person only.** Longer is the usual reason — someone who was being interrupted too often gets an hour instead of fifteen minutes — but shorter works too. +- The change takes effect at the next scheduled wake-up, within a few minutes. It never affects anyone else, and clearing the field puts them straight back on the shared setting. +- It is a question of *when*, not of *whether*: an agent an admin has switched off stays off for everybody, whatever any individual interval says. + +The other three agents have no per-person version of this. The lints read a store only its owner edits, and the review is pinned to an hour of the night — neither has a cadence that depends on the person. diff --git a/docs/tasks.md b/docs/tasks.md new file mode 100644 index 0000000..4749dd4 --- /dev/null +++ b/docs/tasks.md @@ -0,0 +1,49 @@ +# Background tasks (work that keeps running while you talk) + +Some requests take minutes rather than seconds — reading a long document, searching the web thoroughly, crunching a folder of files.

Skald typically runs on a machine on the home network and is opened at an address like `http://192.168.1.50:9000` — plain `http` on a non-local address — and there the browser hides the microphone entirely. The chat says so with an error message when the button is pressed. + +What to suggest, in order of how well it holds up: + +1. **Open Skald at `http://localhost:9000` instead of the IP address.** Works instantly, but only on the machine Skald itself runs on. +2. **Put Skald behind HTTPS.** Configured once, on the server, and then every device works — phones included. A Tailscale mesh ([plugins/remote_connectivity.md](plugins/remote_connectivity.md)) gives a hostname and a real certificate; a reverse proxy such as Caddy is the other common route. This is the answer for anyone using Skald from more than one device. +3. **Allow the insecure address in the browser's settings.** Chrome, Edge and Brave have a flag (`chrome://flags/#unsafely-treat-insecure-origin-as-secure`) that accepts the exact origin, e.g. `http://192.168.1.50:9000`, and needs a relaunch. Firefox has `dom.securecontext.allowlist` in `about:config`, taking the bare hostname. It has to be redone on every device and every browser profile, and these flags are explicitly temporary. + +**Safari has no such setting** — neither on Mac nor on iPhone/iPad. For Safari users, HTTPS is the only route. Since iPhones and iPads cannot use anything but Safari's engine, that also means voice input on a phone needs HTTPS regardless of which browser is installed. + +The other messages the microphone button can produce are ordinary: access **denied** means the browser was told no for this site and the permission has to be re-allowed in its settings; **not supported** means the browser is too old or is running with media features stripped out. diff --git a/install-nightly.sh b/install-nightly.sh index 7ef694e..cd7249b 100755 --- a/install-nightly.sh +++ b/install-nightly.sh @@ -127,6 +127,43 @@ stop_existing_service() { fi } +# ── systemd user lingering ──────────────────────────────────────────────────── +# A `systemctl --user` unit runs under the per-user manager (user@UID.service), +# which systemd starts at first login and STOPS when the user's last session +# ends — taking every user service down with it.

The quality of an MCP server is measured by how well it enables LLMs to accomplish real-world tasks. - ---- - -# Process - -## 🚀 High-Level Workflow - -Creating a high-quality MCP server involves four main phases: - -### Phase 1: Deep Research and Planning - -#### 1.1 Understand Modern MCP Design - -**API Coverage vs. Workflow Tools:** -Balance comprehensive API endpoint coverage with specialized workflow tools. Workflow tools can be more convenient for specific tasks, while comprehensive coverage gives agents flexibility to compose operations. Performance varies by client—some clients benefit from code execution that combines basic tools, while others work better with higher-level workflows. When uncertain, prioritize comprehensive API coverage. - -**Tool Naming and Discoverability:** -Clear, descriptive tool names help agents find the right tools quickly. Use consistent prefixes (e.g., `github_create_issue`, `github_list_repos`) and action-oriented naming. - -**Context Management:** -Agents benefit from concise tool descriptions and the ability to filter/paginate results. Design tools that return focused, relevant data. Some clients support code execution which can help agents filter and process data efficiently. - -**Actionable Error Messages:** -Error messages should guide agents toward solutions with specific suggestions and next steps. - -#### 1.2 Study MCP Protocol Documentation - -**Navigate the MCP specification:** - -Start with the sitemap to find relevant pages: `https://modelcontextprotocol.io/sitemap.xml` - -Then fetch specific pages with `.md` suffix for markdown format (e.g., `https://modelcontextprotocol.io/specification/draft.md`). - -Key pages to review: -- Specification overview and architecture -- Transport mechanisms (streamable HTTP, stdio) -- Tool, resource, and prompt definitions - -#### 1.3 Study Framework Documentation - -**Recommended stack:** -- **Language**: TypeScript (high-quality SDK support and good compatibility in many execution environments e.g. MCPB. Plus AI models are good at generating TypeScript code, benefiting from its broad usage, static typing and good linting tools) -- **Transport**: Streamable HTTP for remote servers, using stateless JSON (simpler to scale and maintain, as opposed to stateful sessions and streaming responses). stdio for local servers. - -**Load framework documentation:** - -- **MCP Best Practices**: [📋 View Best Practices](./reference/mcp_best_practices.md) - Core guidelines - -**For TypeScript (recommended):** -- **TypeScript SDK**: Use WebFetch to load `https://raw.githubusercontent.com/modelcontextprotocol/typescript-sdk/main/README.md` -- [⚡ TypeScript Guide](./reference/node_mcp_server.md) - TypeScript patterns and examples - -**For Python:** -- **Python SDK**: Use WebFetch to load `https://raw.githubusercontent.com/modelcontextprotocol/python-sdk/main/README.md` -- [🐍 Python Guide](./reference/python_mcp_server.md) - Python patterns and examples - -#### 1.4 Plan Your Implementation - -**Understand the API:** -Review the service's API documentation to identify key endpoints, authentication requirements, and data models. Use web search and WebFetch as needed. - -**Tool Selection:** -Prioritize comprehensive API coverage. List endpoints to implement, starting with the most common operations. - ---- - -### Phase 2: Implementation - -#### 2.1 Set Up Project Structure - -See language-specific guides for project setup: -- [⚡ TypeScript Guide](./reference/node_mcp_server.md) - Project structure, package.json, tsconfig.json -- [🐍 Python Guide](./reference/python_mcp_server.md) - Module organization, dependencies - -#### 2.2 Implement Core Infrastructure - -Create shared utilities: -- API client with authentication -- Error handling helpers -- Response formatting (JSON/Markdown) -- Pagination support - -#### 2.3 Implement Tools - -For each tool: - -**Input Schema:** -- Use Zod (TypeScript) or Pydantic (Python) -- Include constraints and clear descriptions -- Add examples in field descriptions - -**Output Schema:** -- Define `outputSchema` where possible for structured data -- Use `structuredContent` in tool responses (TypeScript SDK feature) -- Helps clients understand and process tool outputs - -**Tool Description:** -- Concise summary of functionality -- Parameter descriptions -- Return type schema - -**Implementation:** -- Async/await for I/O operations -- Proper error handling with actionable messages -- Support pagination where applicable -- Return both text content and structured data when using modern SDKs - -**Annotations:** -- `readOnlyHint`: true/false -- `destructiveHint`: true/false -- `idempotentHint`: true/false -- `openWorldHint`: true/false - ---- - -### Phase 3: Review and Test - -#### 3.1 Code Quality - -Review for: -- No duplicated code (DRY principle) -- Consistent error handling -- Full type coverage -- Clear tool descriptions - -#### 3.2 Build and Test - -**TypeScript:** -- Run `npm run build` to verify compilation -- Test with MCP Inspector: `npx @modelcontextprotocol/inspector` - -**Python:** -- Verify syntax: `python -m py_compile your_server.py` -- Test with MCP Inspector - -See language-specific guides for detailed testing approaches and quality checklists. - ---- - -### Phase 4: Create Evaluations - -After implementing your MCP server, create comprehensive evaluations to test its effectiveness. - -**Load [✅ Evaluation Guide](./reference/evaluation.md) for complete evaluation guidelines.** - -#### 4.1 Understand Evaluation Purpose - -Use evaluations to test whether LLMs can effectively use your MCP server to answer realistic, complex questions. - -#### 4.2 Create 10 Evaluation Questions - -To create effective evaluations, follow the process outlined in the evaluation guide: - -1. **Tool Inspection**: List available tools and understand their capabilities -2. **Content Exploration**: Use READ-ONLY operations to explore available data -3. **Question Generation**: Create 10 complex, realistic questions -4. **Answer Verification**: Solve each question yourself to verify answers - -#### 4.3 Evaluation Requirements - -Ensure each question is: -- **Independent**: Not dependent on other questions -- **Read-only**: Only non-destructive operations required -- **Complex**: Requiring multiple tool calls and deep exploration -- **Realistic**: Based on real use cases humans would care about -- **Verifiable**: Single, clear answer that can be verified by string comparison -- **Stable**: Answer won't change over time - -#### 4.4 Output Format - -Create an XML file with this structure: - -```xml - - - Find discussions about AI model launches with animal codenames.

-## Question Guidelines - -### Core Requirements - -1. **Questions MUST be independent** - - Each question should NOT depend on the answer to any other question - - Should not assume prior write operations from processing another question - -2. **Questions MUST require ONLY NON-DESTRUCTIVE AND IDEMPOTENT tool use** - - Should not instruct or require modifying state to arrive at the correct answer - -3. **Questions must be REALISTIC, CLEAR, CONCISE, and COMPLEX** - - Must require another LLM to use multiple (potentially dozens of) tools or steps to answer - -### Complexity and Depth - -4. **Questions must require deep exploration** - - Consider multi-hop questions requiring multiple sub-questions and sequential tool calls - - Each step should benefit from information found in previous questions - -5. **Questions may require extensive paging** - - May need paging through multiple pages of results - - May require querying old data (1-2 years out-of-date) to find niche information - - The questions must be DIFFICULT - -6. **Questions must require deep understanding** - - Rather than surface-level knowledge - - May pose complex ideas as True/False questions requiring evidence - - May use multiple-choice format where LLM must search different hypotheses - -7. **Questions must not be solvable with straightforward keyword search** - - Do not include specific keywords from the target content - - Use synonyms, related concepts, or paraphrases - - Require multiple searches, analyzing multiple related items, extracting context, then deriving the answer - -### Tool Testing - -8. **Questions should stress-test tool return values** - - May elicit tools returning large JSON objects or lists, overwhelming the LLM - - Should require understanding multiple modalities of data: - - IDs and names - - Timestamps and datetimes (months, days, years, seconds) - - File IDs, names, extensions, and mimetypes - - URLs, GIDs, etc. - - Should probe the tool's ability to return all useful forms of data - -9. **Questions should MOSTLY reflect real human use cases** - - The kinds of information retrieval tasks that HUMANS assisted by an LLM would care about - -10. **Questions may require dozens of tool calls** - - This challenges LLMs with limited context - - Encourages MCP server tools to reduce information returned - -11. **Include ambiguous questions** - - May be ambiguous OR require difficult decisions on which tools to call - - Force the LLM to potentially make mistakes or misinterpret - - Ensure that despite AMBIGUITY, there is STILL A SINGLE VERIFIABLE ANSWER - -### Stability - -12. **Questions must be designed so the answer DOES NOT CHANGE** - - Do not ask questions that rely on "current state" which is dynamic - - For example, do not count: - - Number of reactions to a post - - Number of replies to a thread - - Number of members in a channel - -13. **DO NOT let the MCP server RESTRICT the kinds of questions you create** - - Create challenging and complex questions - - Some may not be solvable with the available MCP server tools - - Questions may require specific output formats (datetime vs. epoch time, JSON vs. MARKDOWN) - - Questions may require dozens of tool calls to complete - -## Answer Guidelines - -### Verification - -1. **Answers must be VERIFIABLE via direct string comparison** - - If the answer can be re-written in many formats, clearly specify the output format in the QUESTION - - Examples: "Use YYYY/MM/DD.", "Respond True or False.", "Answer A, B, C, or D and nothing else." - - Answer should be a single VERIFIABLE value such as: - - User ID, user name, display name, first name, last name - - Channel ID, channel name - - Message ID, string - - URL, title - - Numerical quantity - - Timestamp, datetime - - Boolean (for True/False questions) - - Email address, phone number - - File ID, file name, file extension - - Multiple choice answer - - Answers must not require special formatting or complex, structured output - - Answer will be verified using DIRECT STRING COMPARISON - -### Readability - -2. **Answers should generally prefer HUMAN-READABLE formats** - - Examples: names, first name, last name, datetime, file name, message string, URL, yes/no, true/false, a/b/c/d - - Rather than opaque IDs (though IDs are acceptable) - - The VAST MAJORITY of answers should be human-readable - -### Stability - -3. **Answers must be STABLE/STATIONARY** - - Look at old content (e.g., conversations that have ended, projects that have launched, questions answered) - - Create QUESTIONS based on "closed" concepts that will always return the same answer - - Questions may ask to consider a fixed time window to insulate from non-stationary answers - - Rely on context UNLIKELY to change - - Example: if finding a paper name, be SPECIFIC enough so answer is not confused with papers published later - -4. **Answers must be CLEAR and UNAMBIGUOUS** - - Questions must be designed so there is a single, clear answer - - Answer can be derived from using the MCP server tools - -### Diversity - -5. **Answers must be DIVERSE** - - Answer should be a single VERIFIABLE value in diverse modalities and formats - - User concept: user ID, user name, display name, first name, last name, email address, phone number - - Channel concept: channel ID, channel name, channel topic - - Message concept: message ID, message string, timestamp, month, day, year - -6. **Answers must NOT be complex structures** - - Not a list of values - - Not a complex object - - Not a list of IDs or strings - - Not natural language text - - UNLESS the answer can be straightforwardly verified using DIRECT STRING COMPARISON - - And can be realistically reproduced - - It should be unlikely that an LLM would return the same list in any other order or format - -## Evaluation Process - -### Step 1: Documentation Inspection - -Read the documentation of the target API to understand: -- Available endpoints and functionality -- If ambiguity exists, fetch additional information from the web -- Parallelize this step AS MUCH AS POSSIBLE -- Ensure each subagent is ONLY examining documentation from the file system or on the web - -### Step 2: Tool Inspection - -List the tools available in the MCP server: -- Inspect the MCP server directly -- Understand input/output schemas, docstrings, and descriptions -- WITHOUT calling the tools themselves at this stage - -### Step 3: Developing Understanding - -Repeat steps 1 & 2 until you have a good understanding: -- Iterate multiple times -- Think about the kinds of tasks you want to create -- Refine your understanding -- At NO stage should you READ the code of the MCP server implementation itself -- Use your intuition and understanding to create reasonable, realistic, but VERY challenging tasks - -### Step 4: Read-Only Content Inspection - -After understanding the API and tools, USE the MCP server tools: -- Inspect content using READ-ONLY and NON-DESTRUCTIVE operations ONLY -- Goal: identify specific content (e.g., users, channels, messages, projects, tasks) for creating realistic questions -- Should NOT call any tools that modify state -- Will NOT read the code of the MCP server implementation itself -- Parallelize this step with individual sub-agents pursuing independent explorations -- Ensure each subagent is only performing READ-ONLY, NON-DESTRUCTIVE, and IDEMPOTENT operations -- BE CAREFUL: SOME TOOLS may return LOTS OF DATA which would cause you to run out of CONTEXT -- Make INCREMENTAL, SMALL, AND TARGETED tool calls for exploration -- In all tool call requests, use the `limit` parameter to limit results (<10) -- Use pagination - -### Step 5: Task Generation - -After inspecting the content, create 10 human-readable questions: -- An LLM should be able to answer these with the MCP server -- Follow all question and answer guidelines above - -## Output Format - -Each QA pair consists of a question and an answer. The output should be an XML file with this structure: - -```xml - - - Find the project created in Q2 2024 with the highest number of completed tasks. What is the project name? - Website Redesign - - - Search for issues labeled as "bug" that were closed in March 2024. Which user closed the most issues? Provide their username. - sarah_dev - - - Look for pull requests that modified files in the /api directory and were merged between January 1 and January 31, 2024. How many different contributors worked on these PRs? - 7 - - - Find the repository with the most stars that was created before 2023.

What was the primary programming language used in that repository? - Python - -``` - -This question is good because: -- Requires multiple searches to find archived repositories -- Needs to identify which had the most forks before archival -- Requires examining repository details for the language -- Answer is a simple, verifiable value -- Based on historical (closed) data that won't change - -**Example 2: Requires understanding context without keyword matching (Project Management MCP)** -```xml - - Locate the initiative focused on improving customer onboarding that was completed in late 2023. The project lead created a retrospective document after completion. What was the lead's role title at that time? - Product Manager - -``` - -This question is good because: -- Doesn't use specific project name ("initiative focused on improving customer onboarding") -- Requires finding completed projects from specific timeframe -- Needs to identify the project lead and their role -- Requires understanding context from retrospective documents -- Answer is human-readable and stable -- Based on completed work (won't change) - -**Example 3: Complex aggregation requiring multiple steps (Issue Tracker MCP)** -```xml - - Among all bugs reported in January 2024 that were marked as critical priority, which assignee resolved the highest percentage of their assigned bugs within 48 hours? Provide the assignee's username. - alex_eng - -``` - -This question is good because: -- Requires filtering bugs by date, priority, and status -- Needs to group by assignee and calculate resolution rates -- Requires understanding timestamps to determine 48-hour windows -- Tests pagination (potentially many bugs to process) -- Answer is a single username -- Based on historical data from specific time period - -**Example 4: Requires synthesis across multiple data types (CRM MCP)** -```xml - - Find the account that upgraded from the Starter to Enterprise plan in Q4 2023 and had the highest annual contract value.

-### Transport -- **Streamable HTTP**: For remote servers, multi-client scenarios -- **stdio**: For local integrations, command-line tools -- Avoid SSE (deprecated in favor of streamable HTTP) - ---- - -## Server Naming Conventions - -Follow these standardized naming patterns: - -**Python**: Use format `{service}_mcp` (lowercase with underscores) -- Examples: `slack_mcp`, `github_mcp`, `jira_mcp` - -**Node/TypeScript**: Use format `{service}-mcp-server` (lowercase with hyphens) -- Examples: `slack-mcp-server`, `github-mcp-server`, `jira-mcp-server` - -The name should be general, descriptive of the service being integrated, easy to infer from the task description, and without version numbers. - ---- - -## Tool Naming and Design - -### Tool Naming - -1. **Use snake_case**: `search_users`, `create_project`, `get_channel_info` -2. **Include service prefix**: Anticipate that your MCP server may be used alongside other MCP servers - - Use `slack_send_message` instead of just `send_message` - - Use `github_create_issue` instead of just `create_issue` -3. **Be action-oriented**: Start with verbs (get, list, search, create, etc.) -4. **Be specific**: Avoid generic names that could conflict with other servers - -### Tool Design - -- Tool descriptions must narrowly and unambiguously describe functionality -- Descriptions must precisely match actual functionality -- Provide tool annotations (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) -- Keep tool operations focused and atomic - ---- - -## Response Formats - -All tools that return data should support multiple formats: - -### JSON Format (`response_format="json"`) -- Machine-readable structured data -- Include all available fields and metadata -- Consistent field names and types -- Use for programmatic processing - -### Markdown Format (`response_format="markdown"`, typically default) -- Human-readable formatted text -- Use headers, lists, and formatting for clarity -- Convert timestamps to human-readable format -- Show display names with IDs in parentheses -- Omit verbose metadata - ---- - -## Pagination - -For tools that list resources: - -- **Always respect the `limit` parameter** -- **Implement pagination**: Use `offset` or cursor-based pagination -- **Return pagination metadata**: Include `has_more`, `next_offset`/`next_cursor`, `total_count` -- **Never load all results into memory**: Especially important for large datasets -- **Default to reasonable limits**: 20-50 items is typical -

-**Best for**: Remote servers, web services, multi-client scenarios - -**Characteristics**: -- Bidirectional communication over HTTP -- Supports multiple simultaneous clients -- Can be deployed as a web service -- Enables server-to-client notifications - -**Use when**: -- Serving multiple clients simultaneously -- Deploying as a cloud service -- Integration with web applications - -### stdio - -**Best for**: Local integrations, command-line tools - -**Characteristics**: -- Standard input/output stream communication -- Simple setup, no network configuration needed -- Runs as a subprocess of the client - -**Use when**: -- Building tools for local development environments -- Integrating with desktop applications -- Single-user, single-session scenarios - -**Note**: stdio servers should NOT log to stdout (use stderr for logging) - -### Transport Selection - -| Criterion | stdio | Streamable HTTP | -|-----------|-------|-----------------| -| **Deployment** | Local | Remote | -| **Clients** | Single | Multiple | -| **Complexity** | Low | Medium | -| **Real-time** | No | Yes | - ---- - -## Security Best Practices - -### Authentication and Authorization - -**OAuth 2.1**: -- Use secure OAuth 2.1 with certificates from recognized authorities -- Validate access tokens before processing requests -- Only accept tokens specifically intended for your server - -**API Keys**: -- Store API keys in environment variables, never in code -- Validate keys on server startup -- Provide clear error messages when authentication fails - -### Input Validation - -- Sanitize file paths to prevent directory traversal -- Validate URLs and external identifiers -- Check parameter sizes and ranges -- Prevent command injection in system calls -- Use schema validation (Pydantic/Zod) for all inputs - -### Error Handling - -- Don't expose internal errors to clients -- Log security-relevant errors server-side -- Provide helpful but not revealing error messages -- Clean up resources after errors - -### DNS Rebinding Protection - -For streamable HTTP servers running locally: -- Enable DNS rebinding protection -- Validate the `Origin` header on all incoming connections -- Bind to `127.0.0.1` rather than `0.0.0.0` - ---- - -## Tool Annotations - -Provide annotations to help clients understand tool behavior: - -| Annotation | Type | Default | Description | -|-----------|------|---------|-------------| -| `readOnlyHint` | boolean | false | Tool does not modify its environment | -| `destructiveHint` | boolean | true | Tool may perform destructive updates | -| `idempotentHint` | boolean | false | Repeated calls with same args have no additional effect | -| `openWorldHint` | boolean | true | Tool interacts with external entities | - -**Important**: Annotations are hints, not security guarantees. Clients should not make security-critical decisions based solely on annotations. - ---- - -## Error Handling - -- Use standard JSON-RPC error codes -- Report tool errors within result objects (not protocol-level errors) -- Provide helpful, specific error messages with suggested next steps -- Don't expose internal implementation details -- Clean up resources properly on errors - -Example error handling: -```typescript -try { - const result = performOperation(); - return { content: [{ type: "text", text: result }] }; -} catch (error) { - return { - isError: true, - content: [{ - type: "text", - text: `Error: ${error.message}.

mcp.run() - -# Streamable HTTP transport (for remote servers) -if __name__ == "__main__": - mcp.run(transport="streamable_http", port=8000) -``` - -**Transport selection:** -- **stdio**: Command-line tools, local integrations, subprocess execution -- **Streamable HTTP**: Web services, remote access, multiple clients - ---- - -## Code Best Practices - -### Code Composability and Reusability - -Your implementation MUST prioritize composability and code reuse: - -1. **Extract Common Functionality**: - - Create reusable helper functions for operations used across multiple tools - - Build shared API clients for HTTP requests instead of duplicating code - - Centralize error handling logic in utility functions - - Extract business logic into dedicated functions that can be composed - - Extract shared markdown or JSON field selection & formatting functionality - -2. **Avoid Duplication**: - - NEVER copy-paste similar code between tools - - If you find yourself writing similar logic twice, extract it into a function - - Common operations like pagination, filtering, field selection, and formatting should be shared - - Authentication/authorization logic should be centralized - -### Python-Specific Best Practices - -1. **Use Type Hints**: Always include type annotations for function parameters and return values -2. **Pydantic Models**: Define clear Pydantic models for all input validation -3. **Avoid Manual Validation**: Let Pydantic handle input validation with constraints -4. **Proper Imports**: Group imports (standard library, third-party, local) -5. **Error Handling**: Use specific exception types (httpx.HTTPStatusError, not generic Exception) -6. **Async Context Managers**: Use `async with` for resources that need cleanup -7. **Constants**: Define module-level constants in UPPER_CASE - -## Quality Checklist - -Before finalizing your Python MCP server implementation, ensure: - -### Strategic Design -- [ ] Tools enable complete workflows, not just API endpoint wrappers -- [ ] Tool names reflect natural task subdivisions -- [ ] Response formats optimize for agent context efficiency -- [ ] Human-readable identifiers used where appropriate -- [ ] Error messages guide agents toward correct usage - -### Implementation Quality -- [ ] FOCUSED IMPLEMENTATION: Most important and valuable tools implemented -- [ ] All tools have descriptive names and documentation -- [ ] Return types are consistent across similar operations -- [ ] Error handling is implemented for all external calls -- [ ] Server name follows format: `{service}_mcp` -- [ ] All network operations use async/await -- [ ] Common functionality is extracted into reusable functions -- [ ] Error messages are clear, actionable, and educational -- [ ] Outputs are properly validated and formatted - -### Tool Configuration -- [ ] All tools implement 'name' and 'annotations' in the decorator -- [ ] Annotations correctly set (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) -- [ ] All tools use Pydantic BaseModel for input validation with Field() definitions -- [ ] All Pydantic Fields have explicit types and descriptions with constraints -- [ ] All tools have comprehensive docstrings with explicit input/output types -- [ ] Docstrings include complete schema structure for dict/JSON returns -- [ ] Pydantic models handle input validation (no manual validation needed) - -### Advanced Features (where applicable) -- [ ] Context injection used for logging, progress, or elicitation -- [ ] Resources registered for appropriate data endpoints -- [ ] Lifespan management implemented for persistent connections -- [ ] Structured output types used (TypedDict, Pydantic models) -- [ ] Appropriate transport configured (stdio or streamable HTTP) - -### Code Quality -- [ ] File includes proper imports including Pydantic imports -- [ ] Pagination is properly implemented where applicable -- [ ] Filtering options are provided for potentially large result sets -- [ ] All async functions are properly defined with `async def` -- [ ] HTTP client usage follows async patterns with proper context managers -- [ ] Type hints are used throughout the code -- [ ] Constants are defined at module level in UPPER_CASE - -### Testing -- [ ] Server runs successfully: `python your_server.py --help` -- [ ] All imports resolve correctly -- [ ] Sample tool calls work as expected -- [ ] Error scenarios handled gracefully \ No newline at end of file diff --git a/skills/mcp-builder/scripts/connections.py b/skills/mcp-builder/scripts/connections.py deleted file mode 100644 index ffcd0da..0000000 --- a/skills/mcp-builder/scripts/connections.py +++ /dev/null @@ -1,151 +0,0 @@ -"""Lightweight connection handling for MCP servers.""" -

Use when users want to create a skill from scratch, edit, or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy. ---- - -# Skill Creator - -A skill for creating new skills and iteratively improving them. - -At a high level, the process of creating a skill goes like this: - -- Decide what you want the skill to do and roughly how it should do it -- Write a draft of the skill -- Create a few test prompts and run claude-with-access-to-the-skill on them -- Help the user evaluate the results both qualitatively and quantitatively - - While the runs happen in the background, draft some quantitative evals if there aren't any (if there are some, you can either use as is or modify if you feel something needs to change about them). Then explain them to the user (or if they already existed, explain the ones that already exist) - - Use the `eval-viewer/generate_review.py` script to show the user the results for them to look at, and also let them look at the quantitative metrics -- Rewrite the skill based on feedback from the user's evaluation of the results (and also if there are any glaring flaws that become apparent from the quantitative benchmarks) -- Repeat until you're satisfied -- Expand the test set and try again at larger scale - -Your job when using this skill is to figure out where the user is in this process and then jump in and help them progress through these stages. So for instance, maybe they're like "I want to make a skill for X". You can help narrow down what they mean, write a draft, write the test cases, figure out how they want to evaluate, run all the prompts, and repeat. - -On the other hand, maybe they already have a draft of the skill. In this case you can go straight to the eval/iterate part of the loop. - -Of course, you should always be flexible and if the user is like "I don't need to run a bunch of evaluations, just vibe with me", you can do that instead. - -Then after the skill is done (but again, the order is flexible), you can also run the skill description improver, which we have a whole separate script for, to optimize the triggering of the skill. - -Cool? Cool. - -## Communicating with the user - -The skill creator is liable to be used by people across a wide range of familiarity with coding jargon. If you haven't heard (and how could you, it's only very recently that it started), there's a trend now where the power of Claude is inspiring plumbers to open up their terminals, parents and grandparents to google "how to install npm". On the other hand, the bulk of users are probably fairly computer-literate. - -So please pay attention to context cues to understand how to phrase your communication! In the default case, just to give you some idea: - -- "evaluation" and "benchmark" are borderline, but OK -- for "JSON" and "assertion" you want to see serious cues from the user that they know what those things are before using them without explaining them - -It's OK to briefly explain terms if you're in doubt, and feel free to clarify terms with a short definition if you're unsure if the user will get it. - ---- - -## Creating a skill - -### Capture Intent - -Start by understanding the user's intent. The current conversation might already contain a workflow the user wants to capture (e.g., they say "turn this into a skill"). If so, extract answers from the conversation history first — the tools used, the sequence of steps, corrections the user made, input/output formats observed. The user may need to fill the gaps, and should confirm before proceeding to the next step. - -1. What should this skill enable Claude to do? -2. When should this skill trigger? (what user phrases/contexts) -3. What's the expected output format? -4. Should we set up test cases to verify the skill works? Skills with objectively verifiable outputs (file transforms, data extraction, code generation, fixed workflow steps) benefit from test cases. Skills with subjective outputs (writing style, art) often don't need them. Suggest the appropriate default based on the skill type, but let the user decide. - -### Interview and Research - -Proactively ask questions about edge cases, input/output formats, example files, success criteria, and dependencies. Wait to write test prompts until you've got this part ironed out. - -Check available MCPs - if useful for research (searching docs, finding similar skills, looking up best practices), research in parallel via subagents if available, otherwise inline. Come prepared with context to reduce burden on the user. - -### Write the SKILL.md - -Based on the user interview, fill in these components: - -- **name**: Skill identifier -- **description**: When to trigger, what it does. This is the primary triggering mechanism - include both what the skill does AND specific contexts for when to use it. All "when to use" info goes here, not in the body. Note: currently Claude has a tendency to "undertrigger" skills -- to not use them when they'd be useful. To combat this, please make the skill descriptions a little bit "pushy". So for instance, instead of "How to build a simple fast dashboard to display internal Anthropic data.", you might write "How to build a simple fast dashboard to display internal Anthropic data. Make sure to use this skill whenever the user mentions dashboards, data visualization, internal metrics, or wants to display any kind of company data, even if they don't explicitly ask for a 'dashboard.'" -- **compatibility**: Required tools, dependencies (optional, rarely needed) -- **the rest of the skill :)** - -### Skill Writing Guide - -#### Anatomy of a Skill - -``` -skill-name/ -├── SKILL.md (required) -│ ├── YAML frontmatter (name, description required) -│ └── Markdown instructions -└── Bundled Resources (optional) - ├── scripts/ - Executable code for deterministic/repetitive tasks - ├── references/ - Docs loaded into context as needed - └── assets/ - Files used in output (templates, icons, fonts) -``` - -#### Progressive Disclosure - -Skills use a three-level loading system: -1. **Metadata** (name + description) - Always in context (~100 words) -2. **SKILL.md body** - In context whenever skill triggers (<500 lines ideal) -3. **Bundled resources** - As needed (unlimited, scripts can execute without loading) - -These word counts are approximate and you can feel free to go longer if needed. - -**Key patterns:** -- Keep SKILL.md under 500 lines; if you're approaching this limit, add an additional layer of hierarchy along with clear pointers about where the model using the skill should go next to follow up. -- Reference files clearly from SKILL.md with guidance on when to read them -- For large reference files (>300 lines), include a table of contents - -**Domain organization**: When a skill supports multiple domains/frameworks, organize by variant: -``` -cloud-deploy/ -├── SKILL.md (workflow + selection) -└── references/ - ├── aws.md - ├── gcp.md - └── azure.md -``` -Claude reads only the relevant reference file. - -#### Principle of Lack of Surprise - -This goes without saying, but skills must not contain malware, exploit code, or any content that could compromise system security. A skill's contents should not surprise the user in their intent if described. Don't go along with requests to create misleading skills or skills designed to facilitate unauthorized access, data exfiltration, or other malicious activities. Things like a "roleplay as an XYZ" are OK though. - -#### Writing Patterns - -Prefer using the imperative form in instructions. - -**Defining output formats** - You can do it like this: -```markdown -## Report structure -ALWAYS use this exact template: -# [Title] -## Executive summary -## Key findings -## Recommendations -``` - -**Examples pattern** - It's useful to include examples. You can format them like this (but if "Input" and "Output" are in the examples you might want to deviate a little): -```markdown -## Commit message format -**Example 1:** -Input: Added user authentication with JWT tokens -Output: feat(auth): implement JWT-based authentication -``` - -### Writing Style - -Try to explain to the model why things are important in lieu of heavy-handed musty MUSTs. Use theory of mind and try to make the skill general and not super-narrow to specific examples. Start by writing a draft and then look at it with fresh eyes and improve it. - -### Test Cases - -After writing the skill draft, come up with 2-3 realistic test prompts — the kind of thing a real user would actually say. Share them with the user: [you don't have to use this exact language] "Here are a few test cases I'd like to try. Do these look right, or do you want to add more?" Then run them. - -Save test cases to `evals/evals.json`. Don't write assertions yet — just the prompts. You'll draft assertions in the next step while the runs are in progress. - -```json -{ - "skill_name": "example-skill", - "evals": [ - { - "id": 1, - "prompt": "User's task prompt", - "expected_output": "Description of expected result", - "files": [] - } - ] -} -``` - -See `references/schemas.md` for the full schema (including the `assertions` field, which you'll add later). - -## Running and evaluating test cases - -This section is one continuous sequence — don't stop partway through. Do NOT use `/skill-test` or any other testing skill. - -Put results in `-workspace/` as a sibling to the skill directory. Within the workspace, organize results by iteration (`iteration-1/`, `iteration-2/`, etc.) and within that, each test case gets a directory (`eval-0/`, `eval-1/`, etc.). Don't create all of this upfront — just create directories as you go. - -### Step 1: Spawn all runs (with-skill AND baseline) in the same turn - -For each test case, spawn two subagents in the same turn — one with the skill, one without. This is important: don't spawn the with-skill runs first and then come back for baselines later. Launch everything at once so it all finishes around the same time. - -**With-skill run:** - -``` -Execute this task: -- Skill path: -- Task: -- Input files: -- Save outputs to: /iteration-/eval-/with_skill/outputs/ -- Outputs to save: -``` - -**Baseline run** (same prompt, but the baseline depends on context): -- **Creating a new skill**: no skill at all. Same prompt, no skill path, save to `without_skill/outputs/`. -- **Improving an existing skill**: the old version. Before editing, snapshot the skill (`cp -r /skill-snapshot/`), then point the baseline subagent at the snapshot. Save to `old_skill/outputs/`. - -Write an `eval_metadata.json` for each test case (assertions can be empty for now). Give each eval a descriptive name based on what it's testing — not just "eval-0". Use this name for the directory too. If this iteration uses new or modified eval prompts, create these files for each new eval directory — don't assume they carry over from previous iterations. - -```json -{ - "eval_id": 0, - "eval_name": "descriptive-name-here", - "prompt": "The user's task prompt", - "assertions": [] -} -``` - -### Step 2: While runs are in progress, draft assertions - -Don't just wait for the runs to finish — you can use this time productively. Draft quantitative assertions for each test case and explain them to the user. If assertions already exist in `evals/evals.json`, review them and explain what they check. - -Good assertions are objectively verifiable and have descriptive names — they should read clearly in the benchmark viewer so someone glancing at the results immediately understands what each one checks. Subjective skills (writing style, design quality) are better evaluated qualitatively — don't force assertions onto things that need human judgment. - -Update the `eval_metadata.json` files and `evals/evals.json` with the assertions once drafted. Also explain to the user what they'll see in the viewer — both the qualitative outputs and the quantitative benchmark. - -### Step 3: As runs complete, capture timing data - -When each subagent task completes, you receive a notification containing `total_tokens` and `duration_ms`. Save this data immediately to `timing.json` in the run directory: - -```json -{ - "total_tokens": 84852, - "duration_ms": 23332, - "total_duration_seconds": 23.3 -} -``` - -This is the only opportunity to capture this data — it comes through the task notification and isn't persisted elsewhere. Process each notification as it arrives rather than trying to batch them. - -### Step 4: Grade, aggregate, and launch the viewer - -Once all runs are done: - -1. **Grade each run** — spawn a grader subagent (or grade inline) that reads `agents/grader.md` and evaluates each assertion against the outputs. Save results to `grading.json` in each run directory. The grading.json expectations array must use the fields `text`, `passed`, and `evidence` (not `name`/`met`/`details` or other variants) — the viewer depends on these exact field names. For assertions that can be checked programmatically, write and run a script rather than eyeballing it — scripts are faster, more reliable, and can be reused across iterations. - -2. **Aggregate into benchmark** — run the aggregation script from the skill-creator directory: - ```bash - python -m scripts.aggregate_benchmark /iteration-N --skill-name - ``` - This produces `benchmark.json` and `benchmark.md` with pass_rate, time, and tokens for each configuration, with mean ± stddev and the delta. If generating benchmark.json manually, see `references/schemas.md` for the exact schema the viewer expects. -Put each with_skill version before its baseline counterpart. - -3. **Do an analyst pass** — read the benchmark data and surface patterns the aggregate stats might hide. See `agents/analyzer.md` (the "Analyzing Benchmark Results" section) for what to look for — things like assertions that always pass regardless of skill (non-discriminating), high-variance evals (possibly flaky), and time/token tradeoffs. - -4. **Launch the viewer** with both qualitative outputs and quantitative data: - ```bash - nohup python /eval-viewer/generate_review.py \ - /iteration-N \ - --skill-name "my-skill" \ - --benchmark /iteration-N/benchmark.json \ - > /dev/null 2>&1 & - VIEWER_PID=$! - ``` - For iteration 2+, also pass `--previous-workspace /iteration-`. - - **Cowork / headless environments:** If `webbrowser.open()` is not available or the environment has no display, use `--static ` to write a standalone HTML file instead of starting a server. Feedback will be downloaded as a `feedback.json` file when the user clicks "Submit All Reviews". After download, copy `feedback.json` into the workspace directory for the next iteration to pick up. - -Note: please use generate_review.py to create the viewer; there's no need to write custom HTML. - -5. **Tell the user** something like: "I've opened the results in your browser. There are two tabs — 'Outputs' lets you click through each test case and leave feedback, 'Benchmark' shows the quantitative comparison. When you're done, come back here and let me know." - -### What the user sees in the viewer - -The "Outputs" tab shows one test case at a time: -- **Prompt**: the task that was given -- **Output**: the files the skill produced, rendered inline where possible -- **Previous Output** (iteration 2+): collapsed section showing last iteration's output -- **Formal Grades** (if grading was run): collapsed section showing assertion pass/fail -- **Feedback**: a textbox that auto-saves as they type -- **Previous Feedback** (iteration 2+): their comments from last time, shown below the textbox - -The "Benchmark" tab shows the stats summary: pass rates, timing, and token usage for each configuration, with per-eval breakdowns and analyst observations. - -Navigation is via prev/next buttons or arrow keys. When done, they click "Submit All Reviews" which saves all feedback to `feedback.json`. - -### Step 5: Read the feedback - -When the user tells you they're done, read `feedback.json`: - -```json -{ - "reviews": [ - {"run_id": "eval-0-with_skill", "feedback": "the chart is missing axis labels", "timestamp": "..."}, - {"run_id": "eval-1-with_skill", "feedback": "", "timestamp": "..."}, - {"run_id": "eval-2-with_skill", "feedback": "perfect, love this", "timestamp": "..."} - ], - "status": "complete" -} -``` - -Empty feedback means the user thought it was fine. Focus your improvements on the test cases where the user had specific complaints. - -Kill the viewer server when you're done with it: - -```bash -kill $VIEWER_PID 2>/dev/null -``` - ---- - -## Improving the skill - -This is the heart of the loop. You've run the test cases, the user has reviewed the results, and now you need to make the skill better based on their feedback. - -### How to think about improvements - -1. **Generalize from the feedback.** The big picture thing that's happening here is that we're trying to create skills that can be used a million times (maybe literally, maybe even more who knows) across many different prompts. Here you and the user are iterating on only a few examples over and over again because it helps move faster. The user knows these examples in and out and it's quick for them to assess new outputs. But if the skill you and the user are codeveloping works only for those examples, it's useless. Rather than put in fiddly overfitty changes, or oppressively constrictive MUSTs, if there's some stubborn issue, you might try branching out and using different metaphors, or recommending different patterns of working. It's relatively cheap to try and maybe you'll land on something great. - -2. **Keep the prompt lean.** Remove things that aren't pulling their weight. Make sure to read the transcripts, not just the final outputs — if it looks like the skill is making the model waste a bunch of time doing things that are unproductive, you can try getting rid of the parts of the skill that are making it do that and seeing what happens. - -3. **Explain the why.** Try hard to explain the **why** behind everything you're asking the model to do. Today's LLMs are *smart*. They have good theory of mind and when given a good harness can go beyond rote instructions and really make things happen. Even if the feedback from the user is terse or frustrated, try to actually understand the task and why the user is writing what they wrote, and what they actually wrote, and then transmit this understanding into the instructions. If you find yourself writing ALWAYS or NEVER in all caps, or using super rigid structures, that's a yellow flag — if possible, reframe and explain the reasoning so that the model understands why the thing you're asking for is important. That's a more humane, powerful, and effective approach. - -4. **Look for repeated work across test cases.** Read the transcripts from the test runs and notice if the subagents all independently wrote similar helper scripts or took the same multi-step approach to something. If all 3 test cases resulted in the subagent writing a `create_docx.py` or a `build_chart.py`, that's a strong signal the skill should bundle that script. Write it once, put it in `scripts/`, and tell the skill to use it. This saves every future invocation from reinventing the wheel. - -This task is pretty important (we are trying to create billions a year in economic value here!) and your thinking time is not the blocker; take your time and really mull things over. I'd suggest writing a draft revision and then looking at it anew and making improvements. Really do your best to get into the head of the user and understand what they want and need. - -### The iteration loop - -After improving the skill: - -1. Apply your improvements to the skill -2. Rerun all test cases into a new `iteration-/` directory, including baseline runs. If you're creating a new skill, the baseline is always `without_skill` (no skill) — that stays the same across iterations. If you're improving an existing skill, use your judgment on what makes sense as the baseline: the original version the user came in with, or the previous iteration. -3. Launch the reviewer with `--previous-workspace` pointing at the previous iteration -4. Wait for the user to review and tell you they're done -5. Read the new feedback, improve again, repeat - -Keep going until: -- The user says they're happy -- The feedback is all empty (everything looks good) -- You're not making meaningful progress - ---- - -## Advanced: Blind comparison - -For situations where you want a more rigorous comparison between two versions of a skill (e.g., the user asks "is the new version actually better?"), there's a blind comparison system. Read `agents/comparator.md` and `agents/analyzer.md` for the details. The basic idea is: give two outputs to an independent agent without telling it which is which, and let it judge quality. Then analyze why the winner won. - -This is optional, requires subagents, and most users won't need it. The human review loop is usually sufficient. - ---- - -## Description Optimization - -The description field in SKILL.md frontmatter is the primary mechanism that determines whether Claude invokes a skill. After creating or improving a skill, offer to optimize the description for better triggering accuracy. - -### Step 1: Generate trigger eval queries - -Create 20 eval queries — a mix of should-trigger and should-not-trigger. Save as JSON: - -```json -[ - {"query": "the user prompt", "should_trigger": true}, - {"query": "another prompt", "should_trigger": false} -] -``` - -The queries must be realistic and something a Claude Code or Claude.ai user would actually type. Not abstract requests, but requests that are concrete and specific and have a good amount of detail. For instance, file paths, personal context about the user's job or situation, column names and values, company names, URLs. A little bit of backstory. Some might be in lowercase or contain abbreviations or typos or casual speech. Use a mix of different lengths, and focus on edge cases rather than making them clear-cut (the user will get a chance to sign off on them). - -Bad: `"Format this data"`, `"Extract text from PDF"`, `"Create a chart"` - -Good: `"ok so my boss just sent me this xlsx file (its in my downloads, called something like 'Q4 sales final FINAL v2.xlsx') and she wants me to add a column that shows the profit margin as a percentage. The revenue is in column C and costs are in column D i think"` - -For the **should-trigger** queries (8-10), think about coverage. You want different phrasings of the same intent — some formal, some casual. Include cases where the user doesn't explicitly name the skill or file type but clearly needs it. Throw in some uncommon use cases and cases where this skill competes with another but should win. - -For the **should-not-trigger** queries (8-10), the most valuable ones are the near-misses — queries that share keywords or concepts with the skill but actually need something different. Think adjacent domains, ambiguous phrasing where a naive keyword match would trigger but shouldn't, and cases where the query touches on something the skill does but in a context where another tool is more appropriate. - -The key thing to avoid: don't make should-not-trigger queries obviously irrelevant. "Write a fibonacci function" as a negative test for a PDF skill is too easy — it doesn't test anything. The negative cases should be genuinely tricky. - -### Step 2: Review with user - -Present the eval set to the user for review using the HTML template: - -1. Read the template from `assets/eval_review.html` -2. Replace the placeholders: - - `__EVAL_DATA_PLACEHOLDER__` → the JSON array of eval items (no quotes around it — it's a JS variable assignment) - - `__SKILL_NAME_PLACEHOLDER__` → the skill's name - - `__SKILL_DESCRIPTION_PLACEHOLDER__` → the skill's current description -3. Write to a temp file (e.g., `/tmp/eval_review_.html`) and open it: `open /tmp/eval_review_.html` -4. The user can edit queries, toggle should-trigger, add/remove entries, then click "Export Eval Set" -5. The file downloads to `~/Downloads/eval_set.json` — check the Downloads folder for the most recent version in case there are multiple (e.g., `eval_set (1).json`) - -This step matters — bad eval queries lead to bad descriptions. - -### Step 3: Run the optimization loop - -Tell the user: "This will take some time — I'll run the optimization loop in the background and check on it periodically." - -Save the eval set to the workspace, then run in the background: - -```bash -python -m scripts.run_loop \ - --eval-set \ - --skill-path \ - --model \ - --max-iterations 5 \ - --verbose -``` - -Use the model ID from your system prompt (the one powering the current session) so the triggering test matches what the user actually experiences. - -While it runs, periodically tail the output to give the user updates on which iteration it's on and what the scores look like. - -This handles the full optimization loop automatically. It splits the eval set into 60% train and 40% held-out test, evaluates the current description (running each query 3 times to get a reliable trigger rate), then calls Claude to propose improvements based on what failed. It re-evaluates each new description on both train and test, iterating up to 5 times. When it's done, it opens an HTML report in the browser showing the results per iteration and returns JSON with `best_description` — selected by test score rather than train score to avoid overfitting. - -### How skill triggering works - -Understanding the triggering mechanism helps design better eval queries. Skills appear in Claude's `available_skills` list with their name + description, and Claude decides whether to consult a skill based on that description. The important thing to know is that Claude only consults skills for tasks it can't easily handle on its own — simple, one-step queries like "read this PDF" may not trigger a skill even if the description matches perfectly, because Claude can handle them directly with basic tools. Complex, multi-step, or specialized queries reliably trigger skills when the description matches. - -This means your eval queries should be substantive enough that Claude would actually benefit from consulting a skill. Simple queries like "read file X" are poor test cases — they won't trigger skills regardless of description quality. - -### Step 4: Apply the result - -Take `best_description` from the JSON output and update the skill's SKILL.md frontmatter. Show the user before/after and report the scores. - ---- - -### Package and Present (only if `present_files` tool is available) - -Check whether you have access to the `present_files` tool. If you don't, skip this step. If you do, package the skill and present the .skill file to the user: - -```bash -python -m scripts.package_skill -``` - -After packaging, direct the user to the resulting `.skill` file path so they can install it. - ---- - -## Claude.ai-specific instructions - -In Claude.ai, the core workflow is the same (draft → test → review → improve → repeat), but because Claude.ai doesn't have subagents, some mechanics change. Here's what to adapt: - -**Running test cases**: No subagents means no parallel execution. For each test case, read the skill's SKILL.md, then follow its instructions to accomplish the test prompt yourself. Do them one at a time. This is less rigorous than independent subagents (you wrote the skill and you're also running it, so you have full context), but it's a useful sanity check — and the human review step compensates. Skip the baseline runs — just use the skill to complete the task as requested. - -**Reviewing results**: If you can't open a browser (e.g., Claude.ai's VM has no display, or you're on a remote server), skip the browser reviewer entirely. Instead, present results directly in the conversation. For each test case, show the prompt and the output. If the output is a file the user needs to see (like a .docx or .xlsx), save it to the filesystem and tell them where it is so they can download and inspect it. Ask for feedback inline: "How does this look? Anything you'd change?" - -**Benchmarking**: Skip the quantitative benchmarking — it relies on baseline comparisons which aren't meaningful without subagents. Focus on qualitative feedback from the user. - -**The iteration loop**: Same as before — improve the skill, rerun the test cases, ask for feedback — just without the browser reviewer in the middle. You can still organize results into iteration directories on the filesystem if you have one. - -**Description optimization**: This section requires the `claude` CLI tool (specifically `claude -p`) which is only available in Claude Code. Skip it if you're on Claude.ai. - -**Blind comparison**: Requires subagents. Skip it. - -**Packaging**: The `package_skill.py` script works anywhere with Python and a filesystem. On Claude.ai, you can run it and the user can download the resulting `.skill` file. - -**Updating an existing skill**: The user might be asking you to update an existing skill, not create a new one. In this case: -- **Preserve the original name.** Note the skill's directory name and `name` frontmatter field -- use them unchanged. E.g., if the installed skill is `research-helper`, output `research-helper.skill` (not `research-helper-v2`). -- **Copy to a writeable location before editing.** The installed skill path may be read-only. Copy to `/tmp/skill-name/`, edit there, and package from the copy. -- **If packaging manually, stage in `/tmp/` first**, then copy to the output directory -- direct writes may fail due to permissions. - ---- - -## Cowork-Specific Instructions - -If you're in Cowork, the main things to know are: - -- You have subagents, so the main workflow (spawn test cases in parallel, run baselines, grade, etc.) all works. (However, if you run into severe problems with timeouts, it's OK to run the test prompts in series rather than parallel.) -- You don't have a browser or display, so when generating the eval viewer, use `--static ` to write a standalone HTML file instead of starting a server. Then proffer a link that the user can click to open the HTML in their browser. -- For whatever reason, the Cowork setup seems to disincline Claude from generating the eval viewer after running the tests, so just to reiterate: whether you're in Cowork or in Claude Code, after running tests, you should always generate the eval viewer for the human to look at examples before revising the skill yourself and trying to make corrections, using `generate_review.py` (not writing your own boutique html code). Sorry in advance but I'm gonna go all caps here: GENERATE THE EVAL VIEWER *BEFORE* evaluating inputs yourself. You want to get them in front of the human ASAP! -- Feedback works differently: since there's no running server, the viewer's "Submit All Reviews" button will download `feedback.json` as a file. You can then read it from there (you may have to request access first). -- Packaging works — `package_skill.py` just needs Python and a filesystem. -- Description optimization (`run_loop.py` / `run_eval.py`) should work in Cowork just fine since it uses `claude -p` via subprocess, not a browser, but please save it until you've fully finished making the skill and the user agrees it's in good shape. -- **Updating an existing skill**: The user might be asking you to update an existing skill, not create a new one.

It never did anything — a _user_ manager has no view of system units, so the ordering was silently ignored rather than merely advisory, and keeping it suggested a guarantee that was not there.

Ours are always `skald-{userid}`. + +**Also**: the uninstaller now reports that systemd lingering is still enabled and how to turn it off, rather than disabling it.

- Optimizing your skill's description. This page updates automatically as Claude tests different versions of your skill's description. Each row is an iteration — a new description attempt. The columns show test queries: green checkmarks mean the skill triggered correctly (or correctly didn't trigger), red crosses mean it got it wrong.

Instead, try to generalize from the failures to broader categories of user intent and situations where this skill would be useful or not useful. The reason for this is twofold: - -1.
