when user wants to start heartbeat monitoring, recurring health checks, the full heartbeat ecosystem, scheduled maintenance, or autonomous reflection loops
The Heartbeat Ecosystem keeps agent-studio healthy, indexed, and informed by running 7 background loops via Claude Code's cron scheduler (CronCreate/CronList/CronDelete).
Key constraint — session-scoped: All loops die when the terminal closes. Use Loop 0 (auto-reschedule) to prevent silent 3-day expiry, and re-run Quick-Start commands after each session restart.
Quick-Start — Activate All Loops Now
Run these /loop commands in your Claude Code session:
/loop 2h Heartbeat tick: Spawn heartbeat-orchestrator subagent via Task({ task_id: 'hb-reflection-' + Date.now(), subagent_type: 'heartbeat-orchestrator' }) to run reflection-check.cjs. Reply HEARTBEAT_OK after spawning.
/loop 4h Heartbeat tick: Spawn heartbeat-orchestrator subagent via Task({ task_id: 'hb-indexing-' + Date.now(), subagent_type: 'heartbeat-orchestrator' }) to check mtime of .claude/context/code-index/metadata.json and reindex if older than 4 hours or missing. Reply HEARTBEAT_OK after spawning.
/loop 30m Heartbeat tick: Spawn heartbeat-orchestrator subagent via Task({ task_id: 'hb-drain-' + Date.now(), subagent_type: 'heartbeat-orchestrator' }) to run context-drain.cjs and report stdout. Reply HEARTBEAT_OK after spawning.
/loop 24h Heartbeat tick: Spawn heartbeat-orchestrator subagent via Task({ task_id: 'hb-evolution-' + Date.now(), subagent_type: 'heartbeat-orchestrator' }) to run evolution-check.cjs. Reply HEARTBEAT_OK after spawning.
The 7 Heartbeat Loops
Loop 0: Auto-Reschedule (every 2 days — MANDATORY)
Prevents silent 3-day expiry. CRITICAL ORDER: Always CronCreate new tasks BEFORE CronDelete old ones.
CronCreate({
schedule: '0 0 */2 * *',
task: 'Self-maintenance: CronList() to inventory active tasks. Identify missing heartbeat loops from the expected set (reflection-2h, evolution-24h, briefing-8am, indexing-4h, drain-30m, telegram-5m, research-7am, reschedule-2d). Recreate any missing tasks using schedules in .claude/context/plans/heartbeat-ecosystem-design-2026-03-07.md. Report recreated task IDs.',
});
Loop 1: Continuous Reflection (every 2h)
Extracts patterns from session transcripts before they are lost.
CronCreate({
schedule: '0 */2 * * *',
task: "Heartbeat tick: Spawn heartbeat-orchestrator subagent via Task({ task_id: 'hb-reflection-' + Date.now(), subagent_type: 'heartbeat-orchestrator' }) to execute this tick. The orchestrator must: (1) call TaskUpdate(in_progress), (2) run `node .claude/tools/cli/reflection-check.cjs`, (3) if stdout is HEARTBEAT_OK, call TaskUpdate(completed) and exit. Do NOT run the script directly in the router session. Reply HEARTBEAT_OK immediately after spawning.",
});
Loop 2: Agent Evolution (every 24h at 3am)
Applies accumulated learnings to improve agent definitions.
CronCreate({
schedule: '0 3 * * *',
task: "Heartbeat tick: Spawn heartbeat-orchestrator subagent via Task({ task_id: 'hb-evolution-' + Date.now(), subagent_type: 'heartbeat-orchestrator' }) to execute this tick. The orchestrator must: (1) call TaskUpdate(in_progress), (2) run `node .claude/tools/cli/evolution-check.cjs`, (3) if stdout is HEARTBEAT_OK, call TaskUpdate(completed) and exit. Do NOT run the script directly in the router session. Reply HEARTBEAT_OK immediately after spawning.",
});
Loop 3: Morning Briefing (8am weekdays)
Summarizes overnight state and suggests priority work.
CronCreate({
schedule: '0 8 * * 1-5',
task: 'Morning briefing: Spawn researcher via Task() to read issues.md, learnings.md, git log, and generate morning briefing report. Do NOT wait for sub-agent. Reply HEARTBEAT_OK and exit.',
});
Loop 4: Codebase Indexing (every 4h)
Keeps hybrid search index fresh.
CronCreate({
schedule: '0 */4 * * *',
// Fixed 2026-04-21: was bm25-index.json which never exists — real artifact is metadata.jsontask: "Heartbeat tick: Spawn heartbeat-orchestrator subagent via Task({ task_id: 'hb-indexing-' + Date.now(), subagent_type: 'heartbeat-orchestrator' }) to execute this tick. The orchestrator must: (1) call TaskUpdate(in_progress), (2) check mtime of .claude/context/code-index/metadata.json via Bash; if older than 4 hours or missing, run `pnpm code:index:reindex`, (3) call TaskUpdate(completed) and exit. Do NOT run the script directly in the router session. Reply HEARTBEAT_OK immediately after spawning.",
});
Loop 5: Context Drain + Clear (every 30min)
Detects pipeline idle state — warns user, does NOT auto-clear.
CronCreate({
schedule: '*/30 * * * *',
task: "Heartbeat tick: Spawn heartbeat-orchestrator subagent via Task({ task_id: 'hb-drain-' + Date.now(), subagent_type: 'heartbeat-orchestrator' }) to execute this tick. The orchestrator must: (1) call TaskUpdate(in_progress), (2) run `node .claude/tools/cli/context-drain.cjs`, (3) reply with the exact stdout output, then call TaskUpdate(completed) and exit. Do NOT run the script directly in the router session. Reply HEARTBEAT_OK immediately after spawning.",
});
Loop 6: Telegram Polling (every 5min)
Polls Telegram Bot API for user messages and routes to agents.
Configuration required:
Create Telegram bot via @BotFather → get token
Set TELEGRAM_BOT_TOKEN=your_token in .env
Start loop after .env is configured
CronCreate({
schedule: '*/5 * * * *',
task: "Heartbeat tick: Spawn heartbeat-orchestrator subagent via Task({ task_id: 'hb-telegram-' + Date.now(), subagent_type: 'heartbeat-orchestrator' }) to execute this tick. The orchestrator must: (1) call TaskUpdate(in_progress), (2) run `node .claude/tools/cli/telegram-poll.cjs`, (3) if stdout is HEARTBEAT_OK, call TaskUpdate(completed) and exit. Do NOT run the script directly in the router session. Reply HEARTBEAT_OK immediately after spawning.",
});
Discord note: Discord uses webhooks (push-based) rather than polling. Send messages via Discord webhook URL, but receiving requires a persistent process — recommend Telegram for bidirectional communication.
Loop 7: ArXiv + Exa Research Digest (daily at 7am)
Surfaces relevant academic papers and web news. Delegates to the dedicated monitor skills.
CronCreate({
schedule: '0 7 * * *',
task: 'Research digest: Spawn researcher via Task() to invoke arxiv-monitor and exa-monitor skills. Do NOT wait for sub-agent. Reply HEARTBEAT_OK and exit.',
});
Dedicated skills:arxiv-monitor (every 6h standalone) | exa-monitor (every 4h standalone)
Config:ARXIV_KEYWORDS and EXA_MONITOR_TOPICS env vars (see .env.example)
