feat: add session advisor and transcript rendering updates - #75
Merged
Conversation
ContextMemory gains a monotonic historyRevision counter that is bumped only when history is rewritten (clear, undo, trimHistory, applyCompaction), never on plain appends, so the session advisor can detect rewrites and resync its view of the main agent's history.
Adds the AdvisorStatusEvent interface and matching zod schema for advisor.status events, carrying advisor id, name, runtime status, enabled flag, and optional model and message, registered in the agent event union next to hook.status. Extends the event tests with a validation case.
Adds the advisor-config types and discovery/normalization of WATCHDOG.md and WATCHDOG.yml/yaml files from user and project scopes, with per-advisor settings such as enabled state, consecutive-failure limits, and tool selection. Adds advisor.tools to the config schema.
Rewrites SessionAdvisor into a multi-advisor runtime: one reviewer agent per configured advisor, with persistent per-advisor state for status, enable overrides, consecutive-failure limits, tool selection, and JSONL transcripts of notes and cost. Notes are XML-escaped and attributed to the issuing advisor, and advisor.status events are emitted. Falls back to the legacy single-advisor config when no WATCHDOG files exist. Sessions gain an emitEvents option for advisor subagents and close the advisor on shutdown.
Adds getAdvisorStatus, setAdvisorEnabled, and reloadAdvisor to the session API surface, implemented by delegating to the session advisor runtime. Re-exports the advisor status event and the advisor-config types from the package index.
Adds getAdvisorStatus, setAdvisorEnabled, and reloadAdvisor to the RPC client plus a SessionAdvisor facade on Session. Re-exports the advisor status event and status types, and covers the new event in the event-type switch test.
Adds the /advisor command with on, off, status, reload, and toggle verbs, wired through dispatch, the builtin command registry, and argument completions. The handler renders advisor runtime details and reports success only when the runtime applied the change. advisor.status events render as a status line per advisor, and the parity matrix registers the command and event.
The transcript is now a TranscriptContainer (extends GutterContainer) where every child carries a role (durable, live-durable, or ephemeral) and an edge-blank policy: blanks are trimmed for opted-in children, a single blank separator row is inserted between durable blocks, and renderedRowsAfterChild exposes exact row accounting for scroll math. Bare addChild now throws.
Migrates every transcript append/insert site in the TUI (slash commands, controllers, and host chrome) to addTranscriptChild, addTranscriptChildAt, and replaceTranscriptChild with explicit role and edge-blank metadata. Updates the affected tests to the new container surface.
While a thinking block streams it renders in the activity container instead of the transcript; on completion it is finalized, removed from the activity pane, and inserted into the transcript as a durable entry, and disposal detaches it from the activity pane first. The shared tool-output toggle now also expands activity-pane children.
Running workflow member rows now spin with the shared BRAILLE_SPINNER_FRAMES instead of the half-circle frames, and the running phase has a braille fallback glyph. Updates mission-control, activity-pane, and message-flow assertions.
Adds a Session Advisor section to the slash command reference covering the /advisor status, on, off, toggle, and reload verbs and their availability.
Minor for the session advisor feature (CLI and SDK), patches for the activity-pane thinking stream and the workflow spinner glyphs.

In `@apps/pythinker-code/src/tui/commands/registry.ts`:
- Around line 197-204: Update the advisor command’s availability function in the
registry so an omitted argument, which defaults to status in the advisor command
handler, is also classified as always available during an active session; retain
idle-only availability for other advisor actions.
In `@apps/pythinker-code/src/tui/components/chrome/transcript-container.ts`:
- Around line 61-139: Reduce per-frame allocations in
TranscriptContainer.renderedRowsAfterChild, renderedChildren, normalizeRows,
rowsForSegments, and render by replacing slice/map/filter chains with indexed
loops, computing following rows and separator state directly without a following
array, returning rows directly for the preserve edgeBlankPolicy, and appending
rendered rows directly into the final output instead of mapping afterward.
Preserve existing normalization, visibility, separator, and gutter behavior.
In `@apps/pythinker-code/test/tui/components/chrome/transcript-container.test.ts`:
- Line 45: Update the StubLines test fixtures at both affected locations to use
the lint-compliant uppercase Unicode escape spelling, replacing \u001b with
\u001B while preserving the existing string contents and test behavior.
In `@packages/agent-core/src/session/advisor-config.ts`:
- Around line 192-206: Bound the ancestor traversal in the projectDirs
construction to the repository or workspace root instead of continuing to
filesystem root, so configs from home and shared parent directories are
excluded. Update the advisor configuration discovery flow and add a regression
test verifying that WATCHDOG.yml files above the detected root are not loaded.
In `@packages/agent-core/src/session/session-advisor.ts`:
- Around line 342-367: Update `#appendReviewContext` to project incremental
history through ContextMemory.project (including trailing open tool-exchange
trimming) before appending it, rather than appending raw history.slice values.
Ensure state.historyCursor advances according to the consumed source history and
aligns only at a closed tool exchange, preserving consistent projected history
with the reset branch; verify the cursor arithmetic against project and
trimTrailingOpenToolExchange.
- Around line 307-317: The advisor timeout path around waitForCurrentTurn must
capture child usage before a timed-out non-persistent turn is removed. Detect
the timeout/abort outcome, update the relevant usage or cost accounting from the
child turn before cleanup, and preserve the existing completed-turn accounting
and non-timeout behavior.

Related Issue
No issue — this branch turns previously uncommitted working-tree changes into reviewable, dependency-ordered commits.
Problem
The working tree carried two finished features with no commit history: a session advisor (second-opinion review) and transcript rendering changes (per-child render metadata, live thinking in the activity pane). They needed to land as small reviewable commits instead of one bulk change, and the TUI changes depended on the backend chain (agent-core → protocol → node-sdk) being built first.

WATCHDOG.md/WATCHDOG.ymlin user and project scopes), per-advisor state (status, enable overrides, consecutive-failure limits, tool selection) and JSONL transcripts of notes and cost.
