Measured on a copy of a real 1.2 GB / 253K-event database, 10 simulated
browsers + 10 hooks/s for 90 s: event-loop delay p99 1239 ms → 32 ms (max
2.0 s → 94 ms), 266 failed requests → 0, 74 → 111 requests/s served, server
RSS 633 → 346 MB. Entry bundle 975 KB raw → 394 KB (106 KB brotli).
Server
- /api/analytics: the events-table scans run in the read worker
(scoped-stats eventAggregates, read-pool job analyticsEvents); runRead takes
maxAgeMs — analytics 10 s, /api/workflows 30 s — keyed by the args
- /api/workflows/skill-usage: +event_type and a tool_name range instead of
LIKE, so it uses idx_events_tool (784 ms → a few ms)
- idx_events_session_type_tool (session_id, event_type, tool_name,
created_at) replaces idx_events_session_type: covering reads for session
stats, the hook dedupes and the import resume point (1.2 s → 20 ms); 64 MB
cache_size and 256 MB mmap_size on both connections
- WAL: the server sets wal_autocheckpoint = 0 and checkpoints PASSIVE every
DASHBOARD_WAL_CHECKPOINT_MS (5 s) from the read worker's own writable
connection; a failed checkpoint restores the automatic one (hook COMMIT p95
109 ms → 15 ms at 100 hooks/s)
- tmux: one list-sessions answers a whole GET /api/lanes and the heal beat
(liveSessions), shared for 1 s and cleared by this process's new/kill —
GET /api/run's sync spawns had blocked 60 s of a 90 s run; the heal beat
skips tmux when nothing runs; attach options chained into 2 spawns
- hooks: TurnDuration/APIError deduped against one read per hook instead of a
query per transcript entry (23 ms/hook on a 763-turn session); one lane
scan per hook; hourly upserts skip rows that did not grow; frames are sent
after the transaction commits (and after the pane binding); new_event
carries its row id; a split pane's (slot 1–9) hooks no longer rebind the
lane's session_id
- watchdog liveness probe runs ps asynchronously; transcript newline scan via
indexOf; startup subagent backfill fingerprints the files it already checked
- pty attach: backpressure (pause past 1 MB unsent, resume under 256 KB)
- static: hashed assets served from their pre-compressed .br/.gz sibling
Client
- hidden tabs neither refetch on WS events nor poll (useLiveRefresh, panes,
lane cards, git header, changes panel, settings); no per-tab hourly
/updates/check (the server already checks)
- refetch storms throttled (workspace tree/session list 3 s, /api/run only on
a run-key change, notification pane lookup only when shown); WS reconnect
jitter; terminal retry backoff 1.5 → 30 s, stops on 1008
- heavier throttles for aggregates (15 s) and detail views; Monitor keepIfSame;
GET in-flight dedupe in request()
- lazy Dashboard/History, xterm (with the first terminal), lane modals, Sagi
(only while enabled); only the active locale loads; Workspace chunk
prefetched on a /workspace deep link
- Sagi: no work while disabled, pupil via CSS variables, memo avatar
- build: .br/.gz siblings, sourcemap hidden; service worker no longer caches
/assets/ (cache v3 drops the old one)
Tests: scripts/test-server.js drops the GIT_DIR-family variables a hook
exports, so a suite run from a linked worktree's pre-commit can no longer
commit into the real repository or set core.bare.

Clean break, no compatibility alias. Renames the product name, the CLI
binary (`ccam` -> `agenthub`), the env var prefix (`CCAM_` ->
`AGENTHUB_`), the Prometheus metric namespace (`ccam_*` ->
`agenthub_*`), the tmux session prefix (`ccam-lane-<id>` ->
`agenthub-lane-<id>`), the per-repo runtime profile directory
(`.ccam/profile` -> `.agenthub/profile`), the lanes state root
(`~/.claude/ccam-lanes` -> `~/.claude/agenthub-lanes`), the bundled
plugins (`plugins/ccam*` -> `plugins/agenthub*`) and their slash
commands (`/ccam-doctor` -> `/agenthub-doctor`, `/ccam:*` ->
`/agenthub:*`).
Because there is no alias, an existing install has to be updated by
hand: rename its `.ccam/profile` directory and any `CCAM_*` variables,
and reinstall the plugin under its new name.
Two other name families are deliberately left alone here, since they are
not just strings: the `Claude-Code-Monitor` repository/marketplace name,
and the `agent-dashboard` npm package plus its `~/.claude/agent-dashboard`
runtime directory, which holds the live database and needs a migration
rather than a rename.
Verified: server 1406/1406, client 459/459, `grep -i ccam` clean across
tracked files, `openapi.yaml` regenerated (95 paths, unchanged count).
Gives watching/thinking real animations (previously static), adds
character to happy/worried/stuck moods, and adds mount-in/press/error-pulse
motion to the avatar button - all gated by prefers-reduced-motion.
fix(test): pin NODE_ENV=production in client-dist-override.test.js
The suite exercises server/index.js's production-only static-serving
gate but never set NODE_ENV itself, so it silently depended on the
ambient shell's NODE_ENV - failing whenever that wasn't "production".
Adds a root `ccam` plugin (`.claude-plugin/plugin.json`, `"source": "./"`) so
`/plugin marketplace add` + `/plugin install ccam@...` is enough on a machine
with nothing but Claude Code: no clone, no npm run setup, no manual npm start.
- scripts/plugin-bootstrap.js: SessionStart hook. Fast-path exit, Node >=22.5
gate (node:sqlite), mkdir lock with stale reclaim, deps installed into
~/.claude/agent-dashboard/runtime/ (never the plugin cache), legacy
checkout-hook cleanup (backed up), ~/.local/bin/ccam launcher, eager UI
build so client routes like /run work immediately, detached server spawn.
- scripts/plugin-open.js, scripts/plugin-doctor.js: /ccam-open, /ccam-doctor.
- server/index.js: DASHBOARD_CLIENT_DIST override (plugin cache is read-only).
- mcp/build/ is committed (plugin MCP servers start before any bootstrap could
build them) and kept honest by scripts/check-mcp-build.js (content hash,
not mtime), enforced by pre-commit when mcp/src changes.
- plugins/ccam-dashboard/.mcp.json moved under plugins/ccam/ with a working
${CLAUDE_PLUGIN_ROOT} path (the old relative path never resolved from a
marketplace-cached subdir).
