> **${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:
```json
{
  "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:

```markdown
---
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.

### 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 n
