${var} — Area to focus on. If empty, runs all checks.

If ${var} is set, focus checks on that specific area.

Read memory/MEMORY.md and the last 2 days of memory/logs/ for context.

Checks (in priority order)

P0 — Failed & stuck skills (check first)

Read memory/cron-state.json. This file tracks every scheduled skill's state and quality metrics:

{
  "skill-name": {
    "last_dispatch": "2026-04-06T12:00:00Z",
    "last_status": "dispatched|success|failed",
    "last_success": "2026-04-06T12:05:00Z",
    "last_failed": "2026-04-05T12:03:00Z",
    "total_runs": 10,
    "total_successes": 8,
    "total_failures": 2,
    "consecutive_failures": 0,
    "success_rate": 0.80,
    "last_quality_score": 4,
    "last_error": "error signature text"
  }
}

Flag these conditions:

• Failed skills: any entry with last_status: "failed". Report the skill name and when it failed.
• Stuck skills: any entry with last_status: "dispatched" where last_dispatch is >45 minutes ago. The skill was dispatched but never reported back — likely hung or crashed before the state update step ran.
• API degradation: any skill with consecutive_failures >= 3. This likely indicates an external API is down or rate-limiting. Report the skill, failure count, and last_error. If multiple skills share similar error signatures, flag the shared dependency.
• Chronic failures: any skill with success_rate < 0.5 (and total_runs >= 5). The skill is failing more than it succeeds.
• Self-check: if heartbeat's own entry shows last_success is >36 hours ago (or missing), note that heartbeat itself may be unreliable.

P1 — Stalled PRs & urgent issues

• Any open PRs stalled > 24h? (use gh pr list)
• Any GitHub issues labeled urgent? (use gh issue list)

P2 — Flagged memory items

• Anything flagged in memory/MEMORY.md that needs follow-up?

P3 — Missing scheduled skills

Read aeon.yml for enabled skills with schedules. Cross-reference with memory/cron-state.json:

• If an enabled skill has no entry at all in the state file, it has never been dispatched by the scheduler.
• If a skill's last_success is >2x its schedule interval old (e.g., a daily skill hasn't succeeded in >48h), flag it.

Do NOT use gh run list for this — the state file is authoritative.

Dedup & notification

Before sending any notification, grep memory/logs/ for the same item. If it appears in the last 48h of logs, skip it. Never notify about the same item twice.

Batch all findings into a single notification, grouped by priority tier:

🔴 FAILED: skill-a (failed 2h ago), skill-b (stuck 1h ago)
🟡 STALLED: PR #42 open 3 days
🔵 MEMORY: follow-up on X flagged 2 days ago

Public status page

After the priority checks (even when everything is green — this step always runs), regenerate docs/status.md so the public GitHub Pages site reflects current fleet health.

Data sources

• memory/cron-state.json — per-skill run state (authoritative)
• memory/issues/INDEX.md — open issue table
• aeon.yml — enabled skill list with schedules
• Latest articles/token-report-*.md (most recent by filename date) — optional; powers the Token Pulse section. Skipped silently when no file exists.

Overall status

Compute one of three overall states from the same signals used above:

• 🔴 DEGRADED — any P0 flag fired (failed skill, stuck skill, consecutive_failures ≥ 3, chronic failures with success_rate < 0.5, heartbeat self-check >36h stale)
• 🟡 WATCH — any P1/P2/P3 flag fired (stalled PRs, urgent issues, flagged memory items, skills >2x their schedule interval old) or any open issue with severity critical or high
• 🟢 OK — no flags at all

Format

Write docs/status.md with Jekyll frontmatter so it renders as a gallery page:

---
layout: default
title: "Status"
permalink: /status/

# Agent Status

**Overall:** 🟢 OK
**Updated:** 2026-04-24 19:06 UTC
**Open issues:** 0
**Next scheduled run:** heartbeat at 20:00 UTC

Auto-generated by the `heartbeat` skill on every run (3× daily at 08:00 / 14:00 / 20:00 UTC). If the Updated timestamp is more than ~8h stale, the agent is not running.

## Token pulse

| Token | Price | 24h | Liquidity | Volume (24h) | FDV |
|-------|-------|-----|-----------|--------------|-----|
| AEON | $0.0000032626 | -11.16% | $223.4K | $41.3K | $326.3K |

## Skill health (last 7 days)

| Skill | Last run | Status | Success rate | Consecutive failures |
|-------|----------|--------|-------------:|---------------------:|

Rules

• Include all enabled skills from aeon.yml (not only those with recent runs). For skills with no entry in cron-state.json, show — for timestamp and not yet run in status.
• Sort the skill table by last-run timestamp descending (most recent first); skills that have never run sink to the bottom.
• Format timestamps as YYYY-MM-DD HH:MM UTC (strip seconds and the Z).
• Success rate shows total_successes / total_runs × 100 rounded to whole percent; display — when total_runs == 0.
• Status column icons: ✅ success, ❌ failed, ⏳ dispatched (if last_dispatch within 45min), 🕸 stuck (if last_dispatch > 45min and last_status still dispatched), — (never run).
• For the Next scheduled run: line, pick the enabled skill with the soonest upcoming cron time relative to now.
• Dedup state: re-running heartbeat overwrites docs/status.md wholesale each time — do not append.
• Never expose values from .env, secrets, or anything outside cron-state.json + issues/INDEX.md + aeon.yml + articles/token-report-*.md. This file is public.

Token pulse rules

• Pick the latest articles/token-report-*.md by filename date (sort descending, take the first match).
• Staleness: if the picked file's date is older than 24h relative to the heartbeat run timestamp, render _No recent token data (latest report YYYY-MM-DD)._ in place of the table — do not lift stale figures into the table.
• No file at all: omit the ## Token pulse section entirely. The status page must still render cleanly with no token row.
• Token symbol: read from memory/MEMORY.md "Tracked Token" table (first row, Token column). If the table is missing, render the heading as ## Token pulse with the symbol column blank.
• Field extraction (regex, tolerant of both old Value | 24h Change and new Now | 24h Δ table layouts):
  • Price: first | Price | row → first $ value in the row → strip whitespace.
  • 24h: same Price row → first ±?\d+(\.\d+)?% token in the row (typically the second cell). Render as written, preserving sign. If absent, render —.
  • Liquidity: first | Liquidity | row → first $ value.
  • Volume (24h): first row whose first cell matches Volume\b.*24h or 24h Volume → first $ value.
  • FDV: first | FDV | row → first $ value.
  • For any field whose row or $ value cannot be located, render — for that cell only — do not skip the section.
• Verdict line: if the source article contains a **Verdict:** LABEL line, append · verdict: LABEL to the source line. If no Verdict line is present (older format), omit the suffix.
• Source link: the trailing _Source: ..._ line names the exact article file used so a reader can verify the numbers.

The file lands on main through the workflow's auto-commit step — no explicit git commands needed in this skill.

Output

If nothing needs attention, log "HEARTBEAT_OK" (plus the overall status page verdict, e.g. HEARTBEAT_OK · STATUS_PAGE=OK) and end your response.

If something needs attention:

1. Send a single concise notification via ./notify (grouped by priority as above)
2. Log the findings and actions taken to memory/logs/${today}.md
3. Log one line with the status-page verdict, e.g. STATUS_PAGE=DEGRADED — wrote docs/status.md
