nntrivi2001 57dc91585d feat: Claude Code Monitor — lanes, pipelines and a merged workspace

Internal SmartGift build of a Claude Code monitoring dashboard.

Lanes: a durable unit of parallel agent work, one per working directory,
tracked across session restarts. Managed lanes are git worktrees the
dashboard provisions and can reset or remove behind a three-check destroy
guard and a counted preflight; adopted lanes are directories you already
own and are never destroyable.

Pipelines: a lane moves through pipeline stages. A stage the agent declares
with evidence renders green; a stage inferred from the tool-event stream
renders dashed amber and never counts as done. Detection is forward-only
within a 30-minute window, and never writes the declared stage.

Workspace: one page at /run with a lane grid, the selected lane's pipeline,
and a full Claude console behind a disclosure.

description
Identify stale and empty Claude Code sessions in the Agent Monitor and explain the cleanup endpoint (POST /api/settings/cleanup), always showing the exact list of what WOULD be removed before anything is deleted. Cleanup permanently deletes data, so this skill previews first and requires explicit user confirmation. Use when tidying the monitoring database.

Session Cleanup

Find prune-worthy sessions and explain cleanup — preview first, delete only on explicit confirmation.

Input

The user provides: $ARGUMENTS

Empty / preview → only show what would be removed (the safe default).
confirm → the user has reviewed the preview and explicitly authorizes deletion.
An optional staleness threshold (e.g. older than 7d) for what counts as stale.

Data Sources

Endpoint	Returns
`GET /api/sessions?limit=N`	session list: id, status, model, cwd, started_at, ended_at, cost, metadata (turn_count, total_turn_duration_ms)
`GET /api/stats`	totals: total_sessions, active_sessions, total_events, events_today, sessions_by_status, agents_by_status
`POST /api/settings/cleanup`	runs the cleanup routine and returns what was removed — DESTRUCTIVE, only after confirmation

Report Sections

1. Baseline

GET /api/stats — record total_sessions, sessions_by_status, total_events. This is the before-state to compare against.

2. Identify candidates

GET /api/sessions?limit=1000. Flag sessions that are:

Empty — zero events and turn_count 0 / null and cost 0 (started but never did anything).
Stale active — status active/working but last activity older than the threshold (default 24h), i.e. never cleanly stopped.
Truncated — no ended_at and no recent events.

3. Preview table (ALWAYS shown)

List every candidate with the reason it qualifies. State the total count and confirm that nothing has been deleted yet.

4. Explain the endpoint

Describe POST /api/settings/cleanup: it prunes empty / orphaned sessions and their dangling events server-side and returns a summary of removed rows. Make clear this is permanent and not reversible from the dashboard.

5. Execute only on confirmation

If — and only if — $ARGUMENTS is confirm (or the user has explicitly approved this run), call POST /api/settings/cleanup, then re-read /api/stats and report the before → after delta. Otherwise stop after the preview and tell the user to re-run with confirm.

Output

A preview Markdown table: id (short) | status | reason | cwd basename | started_at | cost, then a one-line count and the explicit "nothing deleted — re-run with confirm to proceed" notice. On a confirmed run, add a before → after summary using ▲/▼ on the counts. Currency as USD to 4 decimal places.

Safety

This is the ONLY skill in the plugin that mutates data, and only via the one documented endpoint.
NEVER call POST /api/settings/cleanup without an explicit confirm from the user in this turn — previewing is the default.
Never widen scope to POST /api/settings/clear-data or any other destructive endpoint; cleanup of stale/empty sessions only.
If the dashboard is unreachable, tell the user to start it with npm start from the repo root.
