omc-doctor is a Claude Code skill that automatically diagnoses and repairs broken Oh My ClaudeCode plugin installations by checking cached plugin versions, config paths, and common setup failures for developers whose OMC

About

omc-doctor is the Oh My ClaudeCode Doctor skill (level 3) in the oh-my-claudecode repo. It inspects plugin cache directories under ~/.claude/plugins/cache/omc/oh-my-claudecode (honoring CLAUDE_CONFIG_DIR overrides), compares installed semver folders against latest releases via Node one-liners, and walks through fixes for common installation breakages. All path references respect CLAUDE_CONFIG_DIR when set, keeping diagnostics portable across custom config locations. Developers invoke omc-doctor when Claude Code fails to load OMC commands, plugin versions look stale, or post-upgrade hooks leave a partial install. The skill emphasizes repair steps over feature authoring.

  • Runs cross-platform version checks for installed vs latest plugin
  • Scans both global and project-level settings.json for legacy hooks
  • Detects stale cache, missing plugin, and outdated versions with severity labels
  • Provides explicit remediation steps for each diagnosed issue

Task: Run Installation Diagnostics

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

Step 1: Check Plugin Version

# Get installed and latest versions (cross-platform)
node -e "const p=require('path'),f=require('fs'),h=require('os').homedir(),d=process.env.CLAUDE_CONFIG_DIR||p.join(h,'.claude'),b=p.join(d,'plugins','cache','omc','oh-my-claudecode');try{const v=f.readdirSync(b).filter(x=>/^\d/.test(x)).sort((a,c)=>a.localeCompare(c,void 0,{numeric:true}));console.log('Installed:',v.length?v[v.length-1]:'(none)')}catch{console.log('Installed: (none)')}"
npm view oh-my-claude-sisyphus version 2>/dev/null || echo "Latest: (unavailable)"

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  • If INSTALLED != LATEST: WARN - outdated plugin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 for Legacy Hooks in settings.json

Read both ${CLAUDE_CONFIG_DIR:-~/.claude}/settings.json (profile-level) and ./.claude/settings.json (project-level) and check if there's a "hooks" key with entries like:

  • bash ${CLAUDE_CONFIG_DIR:-$HOME/.claude}/hooks/keyword-detector.sh
  • bash ${CLAUDE_CONFIG_DIR:-$HOME/.claude}/hooks/persistent-mode.sh
  • bash ${CLAUDE_CONFIG_DIR:-$HOME/.claude}/hooks/session-start.sh

Diagnosis:

  • If found: CRITICAL - legacy hooks causing duplicates

Step 3: Check for Legacy Bash Hook Scripts

ls -la "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/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 CLAUDE.md

# Check if CLAUDE.md exists
ls -la "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/CLAUDE.md 2>/dev/null

# Check for OMC markers (<!-- OMC:START --> is the canonical marker)
grep -q "<!-- OMC:START -->" "${CLAUDE_CONFIG_DIR:-$HOME/.claude}/CLAUDE.md" 2>/dev/null && echo "Has OMC config" || echo "Missing OMC config in CLAUDE.md"

# Check CLAUDE.md (or deterministic companion) version marker and compare with latest installed plugin cache version
node -e "const p=require('path'),f=require('fs'),h=require('os').homedir(),d=process.env.CLAUDE_CONFIG_DIR||p.join(h,'.claude');const base=p.join(d,'CLAUDE.md');let baseContent='';try{baseContent=f.readFileSync(base,'utf8')}catch{};let candidates=[base];let referenced='';const importMatch=baseContent.match(/CLAUDE-[^ )]*\\.md/);if(importMatch){referenced=p.join(d,importMatch[0]);candidates.push(referenced)}else{const defaultCompanion=p.join(d,'CLAUDE-omc.md');if(f.existsSync(defaultCompanion))candidates.push(defaultCompanion);try{const others=f.readdirSync(d).filter(n=>/^CLAUDE-.*\\.md$/i.test(n)).sort().map(n=>p.join(d,n));for(const o of others){if(candidates.includes(o)===false)candidates.push(o)}}catch{}};let claudeV='(missing)';let claudeSource='(none)';for(const file of candidates){try{const c=f.readFileSync(file,'utf8');const m=c.match(/<!--\\s*OMC:VERSION:([^\\s]+)\\s*-->/i);if(m){claudeV=m[1];claudeSource=file;break}}catch{}};if(claudeV==='(missing)'&&candidates.length>0){claudeV='(missing marker)';claudeSource='scanned deterministic CLAUDE sources';};let pluginV='(none)';try{const b=p.join(d,'plugins','cache','omc','oh-my-claudecode');const v=f.readdirSync(b).filter(x=>/^\\d/.test(x)).sort((a,c)=>a.localeCompare(c,void 0,{numeric:true}));pluginV=v.length?v[v.length-1]:'(none)';}catch{};console.log('CLAUDE.md OMC version:',claudeV);console.log('OMC version source:',claudeSource);console.log('Latest cached plugin version:',pluginV);if(claudeV==='(missing)'||claudeV==='(missing marker)'||pluginV==='(none)'){console.log('VERSION CHECK SKIPPED: missing CLAUDE marker or plugin cache')}else if(claudeV===pluginV){console.log('VERSION MATCH: CLAUDE and plugin cache are aligned')}else{console.log('VERSION DRIFT: CLAUDE.md and plugin versions differ')}"

# Check companion files for file-split pattern (e.g. CLAUDE-omc.md)
find "${CLAUDE_CONFIG_DIR:-$HOME/.claude}" -maxdepth 1 -type f -name 'CLAUDE-*.md' -print 2>/dev/null
while IFS= read -r f; do
  grep -q "<!-- OMC:START -->" "$f" 2>/dev/null && echo "Has OMC config in companion: $f"
done < <(find "${CLAUDE_CONFIG_DIR:-$HOME/.claude}" -maxdepth 1 -type f -name 'CLAUDE-*.md' -print 2>/dev/null)

# Check if CLAUDE.md references a companion file
grep -o "CLAUDE-[^ )]*\.md" "${CLAUDE_CONFIG_DIR:-$HOME/.claude}/CLAUDE.md" 2>/dev/null

Diagnosis:

  • If CLAUDE.md missing: CRITICAL - CLAUDE.md not configured
  • If <!-- OMC:START --> found in CLAUDE.md: OK
  • If <!-- OMC:START --> found in a companion file (e.g. CLAUDE-omc.md): OK - file-split pattern detected
  • If no OMC markers in CLAUDE.md or any companion file: WARN - outdated CLAUDE.md
  • If OMC:VERSION marker is missing from deterministic CLAUDE source scan (base + referenced companion): WARN - cannot verify CLAUDE.md freshness
  • If CLAUDE.md OMC version != Latest cached plugin version: WARN - version drift detected (run omc update or omc setup)

Step 5: Check Ralph Ruby Dependency

Ralph workflows require Ruby. Check for Ruby explicitly so fresh installations get actionable guidance instead of a later opaque Ralph failure.

if command -v ruby >/dev/null 2>&1; then
  echo "Ruby for Ralph: $(ruby --version 2>/dev/null | head -1)"
else
  echo "Ruby for Ralph: MISSING"
  echo "Install Ruby before using Ralph. Ubuntu/Debian: sudo apt update && sudo apt install ruby-full"
  echo "macOS: brew install ruby"
fi

Diagnosis:

  • If Ruby is found: OK - Ralph dependency present
  • If Ruby is missing: WARN - Ralph workflows may fail until Ruby is installed

Step 6: Check for Stale Plugin Cache

# Count versions in cache (cross-platform)
node -e "const p=require('path'),f=require('fs'),h=require('os').homedir(),d=process.env.CLAUDE_CONFIG_DIR||p.join(h,'.claude'),b=p.join(d,'plugins','cache','omc','oh-my-claudecode');try{const v=f.readdirSync(b).filter(x=>/^\d/.test(x));console.log(v.length+' version(s):',v.join(', '))}catch{console.log('0 versions')}"

Diagnosis:

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

Step 7: Check for Legacy Curl-Installed Content

Check for legacy agents, commands, and skills installed via curl (before plugin system). Important: Only flag files whose names match actual plugin-provided names. Do NOT flag user's custom agents/commands/skills that are unrelated to OMC.

# Check for legacy agents directory
ls -la "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/agents/ 2>/dev/null

# Check for legacy commands directory
ls -la "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/commands/ 2>/dev/null

# Check for legacy skills directory
ls -la "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/skills/ 2>/dev/null

Diagnosis:

  • If ~/.claude/agents/ exists with files matching plugin agent names: WARN - legacy agents (now provided by plugin)
  • If ~/.claude/commands/ exists with files matching plugin command names: WARN - legacy commands (now provided by plugin)
  • If ~/.claude/skills/ exists with files matching plugin skill names: WARN - legacy skills (now provided by plugin)
  • If custom files exist that do NOT match plugin names: OK - these are user custom content, do not flag them

Known plugin agent names (check agents/ for these): architect.md, document-specialist.md, explore.md, executor.md, debugger.md, planner.md, analyst.md, critic.md, verifier.md, test-engineer.md, designer.md, writer.md, qa-tester.md, scientist.md, security-reviewer.md, code-reviewer.md, git-master.md, code-simplifier.md

Known plugin skill names (check skills/ for these): ai-slop-cleaner, ask, autopilot, cancel, ccg, configure-notifications, deep-interview, deepinit, external-context, hud, skillify, learner, mcp-setup, omc-doctor, omc-setup, omc-teams, plan, project-session-manager, ralph, ralplan, release, sciomc, setup, skill, team, ultraqa, ultrawork, visual-verdict, writer-memory

Known plugin command names (check commands/ for these): ultrawork.md, deepsearch.md

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 settings.json

Remove the "hooks" section from ${CLAUDE_CONFIG_DIR:-~/.claude}/settings.json (keep other settings intact)

Fix: Legacy Bash Scripts

rm -f "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/hooks/keyword-detector.sh
rm -f "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/hooks/persistent-mode.sh
rm -f "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/hooks/session-start.sh
rm -f "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/hooks/stop-continuation.sh

Fix: Outdated Plugin

# Clear plugin cache (cross-platform)
node -e "const p=require('path'),f=require('fs'),d=process.env.CLAUDE_CONFIG_DIR||p.join(require('os').homedir(),'.claude'),b=p.join(d,'plugins','cache','omc','oh-my-claudecode');try{f.rmSync(b,{recursive:true,force:true});console.log('Plugin cache cleared. Restart Claude Code to fetch latest version.')}catch{console.log('No plugin cache found')}"

Fix: Stale Cache (multiple versions)

# Keep only latest version (cross-platform)
node -e "const p=require('path'),f=require('fs'),h=require('os').homedir(),d=process.env.CLAUDE_CONFIG_DIR||p.join(h,'.claude'),b=p.join(d,'plugins','cache','omc','oh-my-claudecode');try{const v=f.readdirSync(b).filter(x=>/^\d/.test(x)).sort((a,c)=>a.localeCompare(c,void 0,{numeric:true}));v.slice(0,-1).forEach(x=>f.rmSync(p.join(b,x),{recursive:true,force:true}));console.log('Removed',v.length-1,'old version(s)')}catch(e){console.log('No cache to clean')}"

Fix: Missing/Outdated CLAUDE.md

Fetch latest from GitHub and write to ${CLAUDE_CONFIG_DIR:-~/.claude}/CLAUDE.md:

WebFetch(url: "https://raw.githubusercontent.com/Yeachan-Heo/oh-my-claudecode/main/docs/CLAUDE.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 "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/agents "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/agents.bak
# mv "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/commands "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/commands.bak
# mv "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/skills "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/skills.bak

# Or remove directly
rm -rf "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/agents
rm -rf "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/commands
rm -rf "${CLAUDE_CONFIG_DIR:-$HOME/.claude}"/skills

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

FAQ

Where does omc-doctor look for the OMC plugin?

omc-doctor inspects the oh-my-claudecode cache under ~/.claude/plugins/cache/omc/oh-my-claudecode by default, or the equivalent path when CLAUDE_CONFIG_DIR redirects the Claude configuration root.

What does omc-doctor check first?

omc-doctor starts with plugin version validation, reading semver folders in the OMC cache and comparing them to the latest release using cross-platform Node commands before attempting repairs.
