OpenClaw Healthcheck Cron

Create and run a reusable OpenClaw deep healthcheck automation using a cron job plus a script. Use when setting up scheduled OpenClaw health audits, standardizing security/status checks, sanitizing environment-specific values for sharing, and packaging the setup for reuse.

OpenClaw Healthcheck Cron Skill

Create a portable healthcheck automation that runs on a schedule and reports concise findings.

Build the automation

1. Create a script at scripts/healthcheck.sh (or reuse the one in this skill).
2. Keep checks read-only by default.
3. Write artifacts to /tmp/openclaw-healthcheck/YYYY-MM-DD/HHMMSS/.
4. Return a compact summary with severity.

Create the scheduled job

Use an isolated cron agentTurn job that runs twice daily (example: 6am and 7pm local time):

• schedule.kind: cron
• schedule.expr: 0 6,19 * * *
• schedule.tz: set local timezone
• sessionTarget: isolated
• payload.kind: agentTurn
• delivery.mode: announce (or none if reporting is handled inside task)

Use this task pattern:

• Execute bash scripts/healthcheck.sh
• Parse summary line and emit:
  • Verdict: OK | MONITOR | NEEDS_ATTENTION
  • Counts: passed/warn/fail
  • Artifact path
  • Active issues + recommended next action

Sanitize before publishing

Remove or parameterize all local identifiers:

• Usernames, hostnames, phone numbers, chat IDs
• API keys, tokens, webhook URLs
• Absolute personal paths (use placeholders or relative paths)

Replace with variables:

• ${HEALTHCHECK_OUTPUT_DIR:-/tmp/openclaw-healthcheck}
• ${OPENCLAW_HEALTH_TZ:-America/New_York}
• ${HEALTHCHECK_EXCLUDE:-small model,sandbox,groupPolicy}

Validate

1. Run script manually once.
2. Confirm artifact directory and summary format.
3. Run cron job once with cron run.
4. Verify final message is concise and actionable.
