majiayu000 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_count0 / null andcost0 (started but never did anything). - Stale active —
statusactive/working but last activity older than the threshold (default 24h), i.e. never cleanly stopped. - Truncated — no
ended_atand 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/cleanupwithout an explicitconfirmfrom the user in this turn — previewing is the default. - Never widen scope to
POST /api/settings/clear-dataor any other destructive endpoint; cleanup of stale/empty sessions only. - If the dashboard is unreachable, tell the user to start it with
npm startfrom the repo root.
