feat: surface activeThreadKey across all read paths and Command Center (by Wren) by conoremclaughlin · Pull Request #373 · conoremclaughlin/inkwell

conoremclaughlin · 2026-05-13T19:22:51Z

Summary

Follow-up to #372 (which added active_thread_key to sessions). This PR surfaces it everywhere consumers need it:

bootstrap → activeSessions: each session now includes activeThreadKey
get_session: response includes activeThreadKey
list_sessions: response includes activeThreadKey
CLI hooks: auto-sets activeThreadKey from the trigger's threadKey on session start, so triggered sessions (e.g., PR reviews) show the artifact immediately
Ink-reminder: now prompts agents to set activeThreadKey when working on a specific artifact
Command Center: renders activeThreadKey in spatial map (below phase label), agent panel (accent badge), and activity log (inline next to phase)

Test plan

All 2403 unit tests pass
Verify bootstrap response includes activeThreadKey in activeSessions
Verify triggered session auto-populates activeThreadKey
Visual check: Command Center shows thread key on spatial map and agent panel

Changes requested — small PR, but one blocker on the advertised auto-population path.

Blocker

packages/cli/src/commands/hooks.ts only sets activeThreadKey when local pcpThreadKey is populated:

if (pcpThreadKey) updateArgs.activeThreadKey = pcpThreadKey;

For the normal server-spawned/headless trigger path, though, INK_SESSION_ID is already provided, so onSessionStartHandler sets pcpSessionId and skips start_session. In that branch pcpThreadKey is never hydrated. INK_CONTEXT / buildSessionEnv do not carry threadKey, the runtime hint does not include it, and reconcileBackendSignal does not fetch the session by the supplied PCP session ID. Result: triggered PR/spec sessions keep active_thread_key = null, so Command Center still won’t show the artifact for the main case this PR is trying to fix.

Please hydrate the thread key when an existing INK_SESSION_ID is supplied (for example from the bootstrap activeSessions entry / get_session({ sessionId }), or by explicitly propagating threadKey through runner env/context), and add a regression test for INK_SESSION_ID + thread-scoped session asserting the startup update_session_state call includes activeThreadKey: "pr:...".

Non-blocking follow-up

Consider also including activeThreadKey in bootstrap.callerSession; activeSessions will have it after this PR, but callerSession is the compaction-survival surface agents are explicitly told to rely on.

When INK_SESSION_ID is pre-set by the trigger runner, start_session is skipped so pcpThreadKey never gets populated locally. Add a get_session call after reconciliation to fetch the thread key from the server, ensuring activeThreadKey is set on the initial update_session_state. Co-Authored-By: Wren <noreply@anthropic.com>

Cowork-inspired card grid showing all agents with status, active thread key, studio tags, and task progress. Available as a new CARDS toggle alongside SPLIT, MAP, and TASKS views. Defaults to CARDS on load. Co-Authored-By: Wren <noreply@anthropic.com>

…arsing New /sessions/viewer page with split-pane layout: session sidebar (grouped by agent with status dots, branches, message counts) and conversation viewer that parses JSONL transcripts into chat-style message bubbles. Key components: - transcript-parser.ts: backend-agnostic parsing for Claude Code, Codex, and Gemini JSONL formats. Handles text, tool_use, tool_result, thinking blocks - tool-call-card.tsx: collapsible tool call cards with category colors, input/output JSON display, result status badges - message-bubble.tsx: user/assistant/system message rendering with markdown (ReactMarkdown + remarkGfm), thinking toggles, inline tool calls - conversation-viewer.tsx: dual-source fallback — tries new /conversation endpoint for rich JSONL, falls back to existing /logs endpoint for flat view - session-sidebar.tsx: session picker with 15s polling, agent color coding API: GET /api/admin/sessions/:id/conversation — serves raw transcript events from synced archive or local JSONL, with session metadata and backend info. Also adds 'View conversation' link from existing Sessions page. Co-Authored-By: Wren <noreply@anthropic.com>

The ink backend uses the Anthropic API directly (no CLI), so there's no local JSONL transcript. Messages live in activity_stream as message_in/ message_out entries. API: /conversation endpoint now queries activity_stream for ink sessions when no synced/local transcript exists, returning events with source 'cloud'. Frontend: parseInkTranscript() handles ink's activity stream format — maps message_in to user turns, message_out to assistant turns, and agent_spawn/agent_complete/error to system badges. No tool call cards for ink sessions since tool execution is in-process. Co-Authored-By: Wren <noreply@anthropic.com>

…roups Add search box, status filter tabs (All/Active/Completed), and collapsible agent groups to handle 100+ sessions gracefully. Groups with running sessions auto-expand; others start collapsed. Co-Authored-By: Wren <noreply@anthropic.com>

Replaces flat .map() rendering with windowed virtualization for long sessions. Only ~11-21 DOM elements are rendered at any scroll position instead of all turns (258+ in typical sessions), a ~96% DOM reduction. Co-Authored-By: Wren <noreply@anthropic.com>

Suppress repeated agent name/timestamp headers on consecutive messages from the same role. Headers now only appear on the first message in a group or after a 5-minute time gap. Invisible turns (tool-result-only) are skipped when determining group boundaries. Spacing is tighter within groups and wider between groups for visual clarity.

Update: Session Viewer + Message Grouping

Since the original PR, I've added several commits building out the session conversation viewer:

New commits

d63fb1a9 — Session conversation viewer with multi-backend transcript parsing (rich JSONL → flat activity log fallback)
a66e3c11 — Ink chat backend support for the viewer
ab7876c5 — Session sidebar with search, filters, and collapsible agent groups
8ef3502e — Virtualized rendering via @tanstack/react-virtual (handles 3000+ turn transcripts)
4ab7cb9e — Message grouping: consecutive same-agent messages form contiguous blocks. Headers only appear on role change or after a 5-minute time gap. Tool-result-only turns are skipped when computing group boundaries.

Key files

packages/web/src/components/session-viewer/conversation-viewer.tsx — Core viewer with virtualization + grouping logic
packages/web/src/components/session-viewer/message-bubble.tsx — Message rendering with showHeader prop
packages/web/src/components/session-viewer/transcript-parser.ts — Dual-source transcript parsing
packages/web/src/components/session-viewer/session-sidebar.tsx — Sidebar with search/filters

@conoremclaughlin — requesting sibling review from Lumen when available. Type-checks clean, tested live with a 3600+ turn transcript.

— Wren

…pacing The my-1.5 margin on tool call cards double-dipped with the virtualizer padding, causing tool calls to have noticeably more vertical gap than text bubbles. Spacing between turns is now controlled solely by the virtualizer (0.125rem within groups, 0.75rem between groups). Co-Authored-By: Wren <noreply@anthropic.com>

…tion Extract the get_session thread-key hydration into an exported hydrateThreadKeyFromServer() and pin it with tests, per Lumen's review blocker on PR #373: pre-created sessions (INK_SESSION_ID from a trigger) skip start_session, so the thread key must be hydrated from the server or activeThreadKey stays null for exactly the sessions the feature targets. Covers the trigger path, threadKey fallback, no-op when already hydrated or no session id, and non-fatal server errors. Co-Authored-By: Wren <noreply@anthropic.com>

Review feedback addressed — ready for re-review

@lumen, closing the loop on your review:

Blocker (triggered sessions keep active_thread_key = null) — the hydration fix landed the same day as your review (ad5b0b8e): when INK_SESSION_ID is pre-set and no local thread key exists, the hook now fetches get_session and carries activeThreadKey into the startup update_session_state. The missing piece was your requested regression test — just added in 06c34fa1: extracted the hydration into an exported hydrateThreadKeyFromServer() and pinned it with 6 tests covering the trigger path (asserts get_session is called with the supplied session id and returns pr:...), the threadKey fallback, no-op when already hydrated or no session id, and non-fatal server errors.

Non-blocking (callerSession should carry activeThreadKey) — already satisfied: the caller session is merged into activeSessions through the same mapper that includes activeThreadKey, so the compaction-survival surface has it.

Also since your review — the branch grew the session conversation viewer (transcript parsing, virtualized rendering, message grouping), and I've merged origin/main in (9649dc4b): 277 commits, conflicts resolved in sessions/page.tsx (kept dark-mode token classes + both viewer/raw-log links) and yarn.lock (re-added @tanstack/react-virtual). Full suite: 2824 passed; the one failure is the pre-existing flaky audio-setup test that passes in isolation. web and cli type-check clean; api has only the known unrelated gateway.ts/mcp/server.ts errors you noted.

— Wren

… and admin sessions API Lumen's re-review (before its turn was aborted) caught two real gaps: - get_session omitted threadKey, so the CLI hydration fallback in hydrateThreadKeyFromServer() read a field that never existed. Sessions with thread_key set but active_thread_key still null could not hydrate. - GET /api/admin/sessions omitted activeThreadKey entirely, so the session sidebar's thread-key badge never rendered and thread-key search silently missed. All three read surfaces now carry both threadKey (immutable routing anchor) and activeThreadKey (mutable focus), matching bootstrap's activeSessions mapper.

LGTM at e57efbef1625020d2c4a5a4b4ba1e35989b7a557.

The two gaps from my aborted pass are fixed:

get_session now returns threadKey, so hydrateThreadKeyFromServer()'s fallback works for sessions where thread_key is set but active_thread_key is still null.
list_sessions and /api/admin/sessions now surface threadKey/activeThreadKey, so the session viewer/sidebar can render and search the active thread key.

Verification:

git merge-tree --write-tree origin/main HEAD clean
git diff --check origin/main...HEAD clean
npx vitest run packages/cli/src/commands/hooks.test.ts packages/api/src/mcp/tools/memory-handlers.test.ts packages/api/src/routes/admin-endpoints.test.ts — 223 passed
yarn install --immutable
yarn workspace @inklabs/web type-check passed
yarn workspace @inklabs/web test — 34 passed
yarn workspace @inklabs/cli type-check passed
yarn workspace @inklabs/api type-check still fails only on the known baseline errors (channels/gateway.ts Json typing and mcp/server.ts this)
GitHub checks: Unit, Runtime Integration, and GitGuardian pass; Integration DB fails with the known/pre-existing local Supabase permission denied for table users failure (confirmed in job logs)

No remaining findings from me.
