# Doctor Skill

Note: All `~/.codex/...` paths in this guide respect `CODEX_HOME` when that environment variable is set.

## Canonical skill root

OMX installs skills to `${CODEX_HOME:-~/.codex}/skills/` — this is the path current Codex CLI natively loads as its skill root.

`~/.agents/skills/` is a **historical legacy path** from an older Codex CLI release, before Codex settled on `~/.codex` as its home directory. Current Codex CLI and OMX no longer write there.

**In a mixed OMX + plain Codex environment:**
- **Use**: `${CODEX_HOME:-~/.codex}/skills/` (user scope) or `.codex/skills/` (project scope)
- **Clean up if present**: `~/.agents/skills/` — if this still exists alongside the canonical root, Codex's Enable/Disable Skills UI will show duplicate entries for any skill present in both trees
- **Interop rule**: OMX writes only to the canonical path; archive or remove `~/.agents/skills/` once you have confirmed `${CODEX_HOME:-~/.codex}/skills/` is your active root

## Task: Run Installation Diagnostics

You are the OMX Doctor - diagnose and fix installation issues.

### Step 1: Check Plugin Version

```bash
# Get installed version
INSTALLED=$(ls ~/.codex/plugins/cache/omc/oh-my-codex/ 2>/dev/null | sort -V | tail -1)
echo "Installed: $INSTALLED"

# Get latest from npm
LATEST=$(npm view oh-my-codex version 2>/dev/null)
echo "Latest: $LATEST"
```

**Diagnosis**:
- If no version installed: CRITICAL - plugin not installed
- If INSTALLED != LATEST: WARN - outdated plugin
- If multiple versions exist: WARN - stale cache

### Step 2: Check Hook Configuration (config.toml + legacy settings.json)

Check `~/.codex/config.toml` first (current Codex config), then check legacy `~/.codex/settings.json` only if it exists.

Look for hook entries pointing to removed scripts like:
- `bash $HOME/.codex/hooks/keyword-detector.sh`
- `bash $HOME/.codex/hooks/persistent-mode.sh`
- `bash $HOME/.codex/hooks/session-start.sh`

**Diagnosis**:
- If found: CRITICAL - legacy hooks causing duplicates

### Step 3: Check for Legacy Bash Hook Scripts

```bash
ls -la ~/.codex/hooks/*.sh 2>/dev/null
```

**Diagnosis**:
- If `keyword-detector.sh`, `persistent-mode.sh`, `session-start.sh`, or `stop-continuation.sh` exist: WARN - legacy scripts (can cause confusion)

### Step 4: Check AGENTS.md

```bash
# Check if AGENTS.md exists
ls -la ~/.codex/AGENTS.md 2>/dev/null

# Check for OMX marker
grep -q "oh-my-codex Multi-Agent System" ~/.codex/AGENTS.md 2>/dev/null && echo "Has OMX config" || echo "Missing OMX config"
```

**Diagnosis**:
- If missing: CRITICAL - AGENTS.md not configured
- If missing OMX marker: WARN - outdated AGENTS.md

### Step 5: Check for Stale Plugin Cache

```bash
# Count versions in cache
ls ~/.codex/plugins/cache/omc/oh-my-codex/ 2>/dev/null | wc -l
```

**Diagnosis**:
- If > 1 version: WARN - multiple cached versions (cleanup recommended)

### Step 6: Check for Legacy Curl-Installed Content

Check for legacy agents, commands, and historical legacy skill roots from older installs/migrations:

```bash
# Check for legacy agents directory
ls -la ~/.codex/agents/ 2>/dev/null

# Check for legacy commands directory
ls -la ~/.codex/commands/ 2>/dev/null

# Check canonical current skills directory
ls -la ${CODEX_HOME:-~/.codex}/skills/ 2>/dev/null

# Check historical legacy skill directory
ls -la ~/.agents/skills/ 2>/dev/null
```

**Diagnosis**:
- If `~/.codex/agents/` exists with oh-my-codex-related files: WARN - legacy agents (now provided by plugin)
- If `~/.codex/commands/` exists with oh-my-codex-related files: WARN - legacy commands (now provided by plugin)
- If `${CODEX_HOME:-~/.codex}/skills/` exists with OMX skills: OK - canonical current user skill root
- If `~/.agents/skills/` exists: WARN - historical legacy skill root that can overlap with `${CODEX_HOME:-~/.codex}/skills/` and cause duplicate Enable/Disable Skills entries

Look for files like:
- `architect.md`, `researcher.md`, `explore.md`, `executor.md`, etc. in agents/
- `ultrawork.md`, `deepsearch.md`, etc. in commands/
- Any oh-my-codex-related `.md` files in skills/
