An eye next to the paperclip shares what the user has open with their next
message: the page, the folder being browsed, the file open in the viewer and
any highlighted passage (line numbers where a source view exists), plus which
entity a detail page is about. The bag is client-authored {label, value} pairs
in English — the backend only clamps (chars, never bytes), neutralizes the
harness tag and renders one <system-extra> block per message, deduped
consecutively so it appears exactly when the view changed. On by default,
per-device toggle, hover/tap to preview, a chip on every sent message;
docs/view-context.md for users, an updated harness.md clause for the model.
DurableSink resumed the parent through ChatHub::resume(&source), which
resolves whatever session the source currently points at. Since one
source can now carry several conversations (secondary tabs, a reset
since the task started), that pointer is no longer the conversation the
result was delivered into: the recovery ran on the wrong one, found
nothing pending, and returned silently — the delivered task_completed
sat unread until the user's next message drove a normal turn.
The sink already knows the parent session id, so resume it directly
through resume_for_session, keeping the same in-flight guard. The
source lookup and the now-unused pool field go with it.
Adds a crate-level regression test: a completed turn, a StoreSink
delivery, then a recovery — the result must drive a new round.
The session handler is now a thin shell: three entry points in
kernel_turn.rs (run_kernel_turn / recover_turn / resolve_pending_call)
and the ChatSessionHandler. Everything that shaped a Value — projection,
recovery, compaction mechanics, the LLM loop, message building — lives
in agent-loop or behind a loop_adapters trait.
agent-loop:
- projection/ (mod + media): stored history -> wire messages, the one
place provider divergence lives; well-formedness contract, DTL
injections (append-only), media parts. LinearAssembler is now a
Projection + ProjectionHooks config, not its own implementation
- recovery.rs: reap interrupted batches -> resolve the deepest frame's
non-terminal calls (Running by policy + RestartHint, AwaitingHuman
re-asked) -> un-wedge finished children -> cascade up, every frame on
its own agent (B3)
- compaction.rs: split point (never assistant+tool group), transcript,
SUMMARY_PREFIX/preamble/template, the no-tools model call, summary row
- manager: resolve_pending (gate skipped, real ToolContext, then
continue incl. sub-agent); start_loop used by recovery; LiveInput
- delegate: AsyncExecutor + StoreSink for mode:async (durable cron row,
result delivered back into the parent conversation)
- kernel/context/store: support the above (TurnScope via Extensions,
frame lookups, aligned result-text semantics)
skald-core:
- loop_adapters: UserLoopRuntime (D12 - one LoopManager per user),
TurnScope (per-turn state in the Extensions type-map; no scope is
denied), projection_cfg/media_source/tool_digest (Skald's projection
knobs without owning projection code), async_task (CronExecutor +
DurableSink)
- session/handler: stripped to mod.rs + kernel_turn.rs + config.rs +
interface_tools.rs + media.rs; deleted agent_dispatch, approval,
dispatch, emitter, gate, llm_call, llm_loop, message_builder,
messages, outcome, resume
- compactor.rs: policy only (threshold, model pick, CompactionEvent);
mechanics are the crate's
CLAUDE.md updated (recovery, compaction, sub-agents, approval gate,
projection sections now describe the crate-owned flow).
ChatSessionHandler now runs the root turn on the agent-loop kernel
instead of run_agent_turn; sub-agents follow on the same kernel via
DelegateTool. The old loop stays for resume/recovery until phase 3.
agent-loop:
- DelegateTool + AgentCatalog/AgentProfile (full toolset override,
per-child selector/assembler, frame-scoped get), StaticCatalog,
FilteredToolSet; sync flow with sticky child_token; batch via the
generic fan-out
- manager: start_loop skips the registry (children are not
double-driving; they ride the parent's token tree); LoopParams gains
selector/token overrides
- store: get_frame, get_call, set_call_extras; HistoryStore result text
aligned to raw-stored semantics (projection formats)
- events: ApprovalRequired.request_id, AgentSpawned/Finished parent
info; AskUserTool with_name + suggested_answers alias + Question.frame
skald-core (loop_adapters + handler):
- SkaldAssembler (byte-parity port of MessageBuilder's projection:
scratchpad/summary/window, DTL Kimi/Anthropic injection, media, user
coalescing, reasoning echo) + AgentSystemContext (prompt layers,
substitutions, MCP list, shared folders, user profile)
- SkaldAgentCatalog (build_sub_agent_config port), SkaldHumanChannel,
scratchpad/todos tools, execute_task sync/async alias,
LegacyInterfaceTool, PendingLiveInput
- ApprovalGate: PendingWrite diffs via LoopEvent::Host (memory/disk
routed like the fs-tools); SkaldWritePreviewHook for executed-write
diffs; EventTranslator LoopEvent→ServerEvent (display meta, preview,
FileChanged, AgentStart/Done, root-only Done/Truncated/Cancelled)
- handle_message: builds TurnParams and drives the kernel; resume of
pending tools runs first (results belong to the previous turn);
ChatEvent publication stays handler-side; /stop cancels the live loop
- ToolRegistry.get_tool/all_tools; def builders made pub(crate)
Full workspace suite green (179 skald-core, 34 agent-loop, adapters
incl.); two pre-existing doc-test failures fixed along the way.
