Task: Run Installation Diagnostics

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

Step 1: Check Plugin Version

# 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• If INSTALLED != LATEST: WARN - outdated plugin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

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

# 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• If missing OMX marker: WARN - outdated AGENTS.md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

# 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 skills installed via curl (before plugin system):

# 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 for legacy skills directory
ls -la ~/.codex/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/skills/ exists with oh-my-codex-related files: WARN - legacy skills (now provided by plugin)

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/

Auto-Fix (if user confirms)

If issues found, ask user: "Would you like me to fix these issues automatically?"

If yes, apply fixes:

Fix: Legacy Hooks in legacy settings.json

If ~/.codex/settings.json exists, remove the legacy "hooks" section (keep other settings intact).

Fix: Legacy Bash Scripts

rm -f ~/.codex/hooks/keyword-detector.sh
rm -f ~/.codex/hooks/persistent-mode.sh
rm -f ~/.codex/hooks/session-start.sh
rm -f ~/.codex/hooks/stop-continuation.sh

Fix: Outdated Plugin

rm -rf ~/.codex/plugins/cache/omc/oh-my-codex
echo "Plugin cache cleared. Restart Codex CLI to fetch latest version."

Fix: Stale Cache (multiple versions)

# Keep only latest version
cd ~/.codex/plugins/cache/omc/oh-my-codex/
ls | sort -V | head -n -1 | xargs rm -rf

Fix: Missing/Outdated AGENTS.md

Fetch latest from GitHub and write to ~/.codex/AGENTS.md:

WebFetch(url: "https://raw.githubusercontent.com/Yeachan-Heo/oh-my-codex/main/docs/AGENTS.md", prompt: "Return the complete raw markdown content exactly as-is")

Fix: Legacy Curl-Installed Content

Remove legacy agents, commands, and skills directories (now provided by plugin):

# Backup first (optional - ask user)
# mv ~/.codex/agents ~/.codex/agents.bak
# mv ~/.codex/commands ~/.codex/commands.bak
# mv ~/.codex/skills ~/.codex/skills.bak

# Or remove directly
rm -rf ~/.codex/agents
rm -rf ~/.codex/commands
rm -rf ~/.codex/skills

Note: Only remove if these contain oh-my-codex-related files. If user has custom agents/commands/skills, warn them and ask before removing.
