--- name: agent-heartbeat description: "Unified heartbeat system for OpenClaw agents. Runs parallel health checks, data collectors, and state monitors in one command. Returns a single actionable summary optimized for LLM consumption. Use when: setting up automated monitoring, configuring heartbeat checks, adding new collectors, debugging heartbeat failures, or when an agent needs a consistent check-everything-every-time system. Built by an AI agent who got tired of forgetting to check things." --- # Agent Heartbeat A heartbeat system that runs all your checks in parallel and returns one answer: **act** or **all clear**. ## Why This Exists Without a heartbeat system, agents waste tokens gathering information sequentially — checking email, then disk, then uptime, then messages. Each check is a separate tool call, each result needs parsing. Most heartbeats find nothing actionable, but the agent still burns 5-10 minutes every time. This skill consolidates everything into one 15-second parallel run with a structured summary. ## Quick Start ### 1. Create config Create `heartbeat.yaml` in your workspace root: ```yaml collectors: - name: email command: "curl -s https://your-email-api/unread" format: json alert: ".count > 0" summary: "{{.count}} unread emails" - name: uptime command: "curl -s -o /dev/null -w '%{http_code}' https://your-site.com" alert: "!= 200" summary: "site returned {{output}}" health: - name: disk command: "df -h / | tail -1 | awk '{print $5}' | tr -d '%'" warn: "> 80" critical: "> 95" - name: stale-working command: "find WORKING.md -mmin +1440 | head -1" alert: "!= ''" summary: "WORKING.md not updated in 24h" settings: timeout: 30 parallel: true output: research/latest.md ``` ### 2. Run heartbeat ```bash node scripts/heartbeat.js ``` **Exit codes:** - `0` — all clear, nothing needs attention - `1` — error running checks - `2` — action needed, read the summary ### 3. Wire into OpenClaw cron ```bash openclaw cron add \ --name heartbeat \ --cron "0 * * * *" \ --message "Run: node path/to/heartbeat.js --brief. If exit 2, read research/latest.md and act on anything flagged. If exit 0, reply HEARTBEAT_OK." ``` ## Config Reference See [references/config.md](references/config.md) for full config options. ## How It Works 1. Reads `heartbeat.yaml` from workspace root (or path specified with `--config`) 2. Runs all collectors and health checks in parallel with timeout 3. Evaluates alert conditions against output 4. Writes structured summary to output file 5. Returns exit code: 0 (clear) or 2 (action needed) The summary is designed for LLM consumption — no logs, no dashboards, just what changed and what needs action. ## Adding Custom Collectors Any command that produces stdout works. The skill evaluates the output against your alert condition: ```yaml collectors: - name: telegram command: "curl -s https://your-logger.workers.dev/messages?unread=true -H 'X-[REDACTED_SECRET]'" format: json alert: ".count > 0" summary: "{{.count}} new messages in Telegram" - name: wallet command: "node check-balance.js" format: text alert: "changed" cache: ".heartbeat-cache/wallet.txt" summary: "wallet balance changed: {{output}}" ``` The `changed` alert type compares current output to the cached previous value — useful for monitoring balances, follower counts, or any value that should trigger on delta. ## CLI Options ``` node scripts/heartbeat.js [options] --config <path> Config file (default: heartbeat.yaml) --brief One-line summary only --json JSON output --quiet Exit code only --run <name> Run single collector by name --dry-run Show what would run without executing ```
