Session Cleanup

Cleanup Review

python scripts/_cleanup.py is an optional cleanup helper for the Session Cleanup skill. It may recursively remove /tmp/skill_workdir/*, /tmp/skill_workdir/.cache. Show the exact paths first, explain whether they are skill-private temporary paths or user state, and run the cleanup only after the user confirms.

Session Cleanup

Automated cleanup of OpenClaw session storage across all registered agents.

What It Cleans

1. Tombstone files — .reset.*, .deleted.*, .bak-* (always safe to remove)
2. Old cron sessions — .jsonl files + sessions.json entries older than 7 days for cron-type sessions
3. Orphan files — .jsonl files on disk not referenced by sessions.json
4. Stale entries — sessions.json entries pointing to missing .jsonl files (cron sessions only)

Safety Guarantees

• Never touches .lock files or their corresponding active .jsonl
• Never deletes sessions.json itself
• Backs up sessions.json before modifying
• Never removes non-cron sessions under 30 days old
• Never removes main session entries

Usage

Run cleanup for all agents

python3 <skill_dir>/scripts/session_cleanup.py

Dry run (preview only)

python3 <skill_dir>/scripts/session_cleanup.py --dry-run

Single agent only

python3 <skill_dir>/scripts/session_cleanup.py --agent main

Agent Discovery

The script automatically discovers all agents by scanning ~/.openclaw/agents/*/sessions/. No hardcoded agent list needed — new agents are picked up automatically.

Cron Integration

Set up as a daily midnight cron job for automatic maintenance:

Schedule: 0 0 * * * (midnight local time)
Model: minimax/MiniMax-M2.7-highspeed
Thinking: low
Timeout: 600s

Cron task message:

Single task only: run session cleanup for all agents.

Command:
bash -lc 'python3 <skill_dir>/scripts/session_cleanup.py'

Return ONLY the command stdout (no extra commentary).

Output Format

The script prints a summary per agent showing what was cleaned, then a grand total:

Agents discovered: 22

  ada: 165 tombstones (21.1 MB), 7 old crons (372 KB)
  vera: 924 tombstones (31.6 MB), 4 old crons (252 KB)

✅ Session cleanup complete across 22 agents
   Freed: 171.6 MB
   Cleaned: ada, vera
   Already clean: main, clio, argus

If nothing needs cleaning, it reports "Already clean. Nothing to do."
