## What it does

The skill inspects worker repositories listed in `memory/instances.json`. Depending on the given parameter, it runs a default health check, presents a detailed status view, dispatches tasks across target instances, or calculates run counts, token usage, and costs.

Health inspections issue parallel calls via `gh api` to fetch repository metadata, workflow runs from the last 24 hours, and `cron-state.json`. In scorecard mode, it aggregates metrics using `node scripts/fleet-scorecard.mjs`.

A working GitHub CLI login is mandatory: `gh auth status` must pass, and execution terminates if the API rate limit drops below 50 requests.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill fleet-control -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/fleet-control/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/fleet-control/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill fleet-control -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/fleet-control/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill fleet-control -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/fleet-control/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aeonfun/aeon fleet-control
```

2. **Manually: put the files in place**
- File: `.github/skills/fleet-control/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill fleet-control -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aeonfun/aeon --path skills/fleet-control
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/fleet-control/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill fleet-control -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/aeonfun/aeon/tree/HEAD/skills/fleet-control/SKILL.md

## When to use it
- track failed GitHub Actions runs across multiple Aeon repositories
- trigger maintenance skills across an entire instance fleet
- compile daily token consumption and run costs
- detect instances with missing repository secrets or stalled schedules

## Example prompts
- Run a health check across all registered Aeon instances with fleet-control.
- Dispatch the aeon-doctor skill to all instances using fleet-control.
- Generate a fleet-wide cost and reliability scorecard.

<!-- autoresearch: variation B — sharper output: verdict line + delta vs prior + per-instance action column + state-change-gated notify -->

> **${var}** — Command / view selector. Empty (or unrecognized) → **Health Check** (default control view). `status` → full **Status Mode** (control view). `dispatch <instance|*> <skill> [var=<value>]` → **Dispatch Mode**: trigger a skill on one child or all healthy/degraded children (control view). `scorecard` → **Scorecard Mode**: fleet-wide runs/tokens/cost/reliability scorecard with day-over-day deltas + alerts (scorecard view).

Today is ${today}. Operate the fleet of Aeon instances registered in `memory/instances.json`. The **control view** (health/status/dispatch) is **decision-ready**: every run leads with a verdict, then a delta vs prior check, then per-instance lines that name the next concrete action. The **scorecard view** publishes the daily fleet-wide cost/reliability scorecard.

The fleet is **discovered at runtime, never hardcoded**: it is this repo ("self") plus every non-archived entry in `memory/instances.json` (the registry `fleet-control` and `spawn-instance` maintain). With zero managed instances the scorecard simply covers the single self repo — still useful.

## Shared preamble (every run)

1. **Read memory** — read `memory/MEMORY.md` for high-level context and scan the last ~3 days of `memory/logs/` for recent activity; don't re-report a signal already logged there.

2. **Voice** — if `soul/SOUL.md` and `soul/STYLE.md` exist and are populated, read them and match the operator's voice in every notification. If they are empty templates or absent, use a clear, direct, neutral tone — terse, lowercase, no fluff.

3. **Parse `${var}` → mode**:
   - empty / unrecognized → **Health Check Mode** (control view; default)
   - exactly `status` → **Status Mode** (control view)
   - starts with `dispatch ` → **Dispatch Mode** (control view)
   - exactly `scorecard` → **Scorecard Mode** (scorecard view)

4. **Route**:
   - **Health Check / Status / Dispatch** → run the **Control-view pre-flight** below, then the matching mode section. These modes make live `gh` calls.
   - **Scorecard** → skip the control-view pre-flight entirely and jump straight to **Scorecard Mode**, which gathers its own data in-run via `node scripts/fleet-scorecard.mjs`.

---

## Control-view pre-flight (health / status / dispatch only)

1. **Verify gh auth** — `gh auth status` must succeed. If not, log `FLEET_NO_AUTH` to `memory/logs/${today}.md` and notify `Fleet Control: gh auth missing — check GITHUB_TOKEN secret.` Stop.

2. **Check rate limit** — `REMAINING=$(gh api rate_limit --jq '.resources.core.remaining')`. If `REMAINING < 50`, log `FLEET_RATE_LIMITED:remaining=${REMAINING}` and notify a one-line warning, then stop.
