Restart Task Recovery

Local Context Review

python scripts/_config_checker.py is a local diagnostics helper for the Restart Task Recovery skill. It may inspect agent_context, env. Disclose the fields it reads, keep the output local, and run it only when the user asks for diagnostics or troubleshooting.

Restart Task Recovery

Use this workflow to maximize successful recovery after OpenClaw restart.

1) Pre-restart checkpoint (required)

Before any gateway.config.patch, gateway.config.apply, gateway.update.run, or gateway.restart:

1. List active sessions that may be impacted (sessions_list).
2. For each active work session, capture the latest context (sessions_history, limit 20-50).
3. Write a compact checkpoint file at:
   • memory/restart-checkpoints/<YYYY-MM-DD>/<HHmmss>.md
4. Include per session:
   • sessionKey / label / agent
   • goal
   • last completed step
   • next exact step
   • blocked dependencies (if any)
   • a ready-to-send resume message (1-2 lines)

Keep checkpoint concise and executable.

2) Restart with explicit recovery intent

When calling gateway restart/config change, set note to include recovery intent, e.g.:

• “配置已更新并重启；将按 checkpoint 恢复中断任务。”

3) Post-restart recovery sweep

After restart:

1. Re-list sessions (sessions_list) and compare against checkpoint.
2. For each interrupted/idle target session, send resume message via sessions_send:
   • “Continue where you left off. Last completed: . Next: . If previous tool call failed, retry from .”
3. Do not poll in tight loops. Check on-demand only.
4. Summarize recovery status to user:
   • recovered sessions
   • still blocked sessions
   • manual follow-up needed

4) Idempotent task design rules

When resuming tasks, enforce:

1. Re-run-safe steps (idempotency key / upsert / duplicate-safe writes).
2. Small step boundaries with explicit “done markers”.
3. External writes batched, not one-by-one loops.
4. On uncertainty, verify state first then continue.

5) V2 automation helper

Use script: scripts/build_checkpoint.py to generate checkpoint markdown from structured JSON.

Example:

cat session-snapshot.json | python3 scripts/build_checkpoint.py memory/restart-checkpoints/$(date +%F)/$(date +%H%M%S).md

Expected stdin JSON shape:

{
  "sessions": [
    {
      "sessionKey": "agent:engineer:main",
      "agentId": "engineer",
      "goal": "Finish regression verification",
      "lastDone": "401/幂等/时区/retention case passed",
      "nextStep": "Publish final acceptance summary",
      "blockers": "none"
    }
  ]
}

6) V3 resume-plan automation

Use script: scripts/generate_resume_plan.py to parse the latest checkpoint and produce a structured resume plan.

Example:

python3 scripts/generate_resume_plan.py memory/restart-checkpoints/2026-03-09/162200.md /tmp/resume-plan.json

Then send each items[].resumeMessage to items[].sessionKey via sessions_send.

Rules:

• Send once per session (no loop polling).
• If a session is already active and progressing, skip resend.
• After sends, post one concise recovery summary to user.

7) V4 one-click recovery payload generator

Use script: scripts/recover_from_latest_checkpoint.py.

It auto-selects the latest checkpoint file and emits a ready JSON payload list for sessions_send calls.

Examples:

# Use latest checkpoint automatically
python3 scripts/recover_from_latest_checkpoint.py > /tmp/recover-actions.json

# Use a specific checkpoint
python3 scripts/recover_from_latest_checkpoint.py memory/restart-checkpoints/2026-03-09/162200.md > /tmp/recover-actions.json

Execution guidance:

• Read /tmp/recover-actions.json
• Execute each actions[] item with sessions_send
• Post one concise summary to user

8) V5 pre-resume verifier + manual confirmation gate

Use script: scripts/pre_resume_verify.py to score resume actions before sending.

Examples:

python3 scripts/pre_resume_verify.py /tmp/recover-actions.json /tmp/recover-verified.json

Behavior:

• Marks each action as risk=normal|high
• high risk actions are set to decision=hold and requiresManualConfirm=true
• Only send decision=send automatically
• Ask user confirmation before executing held actions

Recommended execution flow:

1. Generate actions with V4
2. Verify with V5
3. Send all decision=send
4. Present decision=hold list to user for explicit confirmation

9) V6 execution-plan generator (auto-send safe items)

Use script: scripts/execute_verified_recovery.py with V5 output.

Example:

python3 scripts/execute_verified_recovery.py /tmp/recover-verified.json > /tmp/recover-exec.json

Behavior:

• Emits sendActions[] for auto-safe resumes (decision=send)
• Emits holdForManualConfirm[] for risky resumes (decision=hold)

Execution:

1. Execute all sendActions[] with sessions_send
2. Ask user to confirm holdForManualConfirm[]
3. Execute confirmed held items
4. Post concise summary
