Oh My Claude Code is a multi-agent orchestration system for Claude Code, coordinating specialized agents, commands, skills, hooks, and workflows. It is designed for developers who want Claude Code to handle coding tasks through coordinated agent roles. Catalogue entries are components of its Claude Code workflow, including agents, commands, skills, hooks, instructions, MCP configuration, and a plugin.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 12 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

What it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00017 | $0.03557 |
| Opus 5 | $0.00009 | $0.01778 |
| Sonnet 5 | $0.00003 | $0.00711 |
| Haiku 4.5 | $0.00002 | $0.00356 |
Grade D, and why
omc-doctor scanned grade D with 3 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
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: Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

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.shbash ${CLAUDE_CONFIG_DIR:-$HOME/.claude}/hooks/persistent-mode.shbash ${CLAUDE_CONFIG_DIR:-$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, orstop-continuation.shexist: 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)

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

omc-doctor is a skill published in the GitHub repository Yeachan-Heo/oh-my-claudecode (39,107 stars, last pushed yesterday), licensed MIT. It adds 17 tokens to every session and 3,557 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it D with 3 findings (reads agent configuration directories, recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
