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.
New skald-core::loop_adapters module — implements the agent-loop trait
surface over existing infrastructure, unused by the current loop (wired
in phase 2):
- SqliteHistory: HistoryStore over chat_sessions_stack/chat_history/
chat_llm_tools/chat_summaries, no schema change; CallState maps 1:1 on
the existing status strings; wire call ids synthesized as tc_{id}
- SkaldSelector: ModelSelector over LlmManager with the agent's strength
captured per-turn (D14); DtlMode → ToolRendering mapping (D15)
- SkaldActivationSource + SkaldToolActivator: DTL catalog + persistence
(activated_tools, anchored at the triggering message) behind the
crate's protocol traits; unifies the grants/persistence split
- ApprovalGate: port of run_approval_gate (pre-approved, engine, fs
fast-path, auto-deny, AwaitingHuman + block on human); a closed human
channel maps to the new GateDecision::Suspend in agent-loop
- SkaldToolSet + CoreToolBridge/McpToolBridge: core-api and MCP tools
run inside the crate's kernel (execution bridged, execute_cmd keeps
its teardown; D7 MarkInterrupted for shell)
- agent-loop: re-export async_trait at root; EventSink::new made public
17 adapter tests green (temp-DB integration); full workspace suite green
(pre-existing honcho-client doc-test failure untouched: missing dev-deps).
