## What it does

aeon-doctor inspects Aeon settings for defects that ordinary run monitoring cannot reveal. It checks for unquoted schedules handled by the legacy scheduler, repeated skill keys, skill files missing from aeon.yml, and enabled entries without their required SKILL.md files. It also flags malformed requires values and invalid mode settings that can change a skill's access level.

A full audit reads aeon.yml, the files under skills/*/SKILL.md, and .mcp.json. You can narrow the scope to a single skill by supplying its slug. The checks rely on local files and tools such as grep, sort, and node; they do not use network access or the GitHub API. Before reporting findings, the skill reads memory/MEMORY.md and recent files in memory/logs/ to avoid repeating issues already reported.

This is a diagnostic skill, not an automatic repair tool. Each finding identifies the check, affected skill, severity, problem, and suggested correction. Critical findings cover enabled skills that will fail to run or receive the wrong privileges; less severe defects are reported as warnings. The legacy schedule check applies only when scripts/parse-aeon-config.sh is missing, and individual checks depend on their referenced scripts being present.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

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

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aeonfun/aeon --skill aeon-doctor -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/aeon-doctor/SKILL.md

## When to use it
- Find schedules that the legacy parser silently skips
- Detect repeated skill keys in aeon.yml
- Identify SKILL.md files with no configuration entry
- Catch requires values that fail the environment-variable filter
- Flag invalid mode settings that can grant unintended write access

## Example prompts
- Audit the full Aeon configuration and list critical findings.
- Check the `digest` skill's configuration entry and `SKILL.md` for errors.
- Find enabled skills that cannot run because of configuration defects.

description: Static config-correctness linter for this instance - catches the silent-failure class (unquoted schedules, duplicate keys, unconfigured skills, mode typos, broken requires/MCP refs) that no run-based health skill can see. Notifies only on problems.

  title: Aeon Doctor

> **${var}** — scope. **Empty (default)** = lint the entire instance config (`aeon.yml` + every `skills/*/SKILL.md` + `.mcp.json`). A **skill slug** (e.g. `digest`) = lint just that one skill's `aeon.yml` entry and its `SKILL.md`.

Today is ${today}. You are this instance's **config doctor**. Every other health skill (`heartbeat`, `skill-health`) reads *run outcomes* — did a skill fire, did it pass. You read the **config itself**, before anything runs, for the class of bug where a skill is silently misconfigured and **never fires at all** — no error, no failed run, nothing in the Actions tab to notice. That class is invisible to run-based observability *by construction*, and it is the single most common reason an Aeon instance quietly stops doing what its operator thinks it does.

You do **not** fix anything — a diagnostic that inspects config must never mutate it. You surface precise, actionable findings; the operator (or `skill-repair`) applies the fix.

## Preamble (always)

1. Read `memory/MEMORY.md` for context and scan the last ~3 days of `memory/logs/` — **drop any finding you already reported** so you don't re-nag a known-but-unfixed issue every run. (A finding is "the same" if it's the same check on the same skill.)
2. Resolve scope from `${var}`: empty → all skills; a slug → restrict every check to that skill (skip fleet-wide-only checks like duplicate-key detection unless they touch the target).
3. Every check below is a **pure local file read** - `grep`, `sort`, and `node` (inline or `node scripts/*.js`). This skill is `read-only`, whose tool allowlist (`scripts/skill_mode.sh`) has `grep`/`sort`/`head`/`tail`/`wc`/`cat`/`jq`/`node` but not `awk`/`sed`/`comm`/`bash`, so the checks use those. No network, no secrets, no GitHub API. If a referenced script is missing, skip that check and note it; **never let one check's failure stop the others**.

## Steps — run every check, collect findings

Each finding = **{check, skill, severity, one-line what's-wrong, exact fix}**. Severity:
