## How To Use

1. **Before building a new skill/hook/agent**: Search these repos first. Someone probably built it.
2. **Use GitHub MCP**: `gh search repos "claude code {topic}" --sort=stars --limit=5`
3. **Use web search**: For latest community patterns from Reddit (r/ClaudeAI, r/ClaudeCode)
4. **Install via SkillKit**: `npx skillkit@latest` for the broadest skill catalog
5. **Check Trail of Bits**: For security patterns before deploying anything public

## Key Patterns Borrowed

- **Tool Search** (46.9% context reduction): `ENABLE_TOOL_SEARCH=auto:5`
- **File protection hooks**: Block writes to lock files and .env
- **Ralph Wiggum loop**: Official autonomous iteration plugin
- **Sandbox-first security**: OS-level isolation > prompt-level permissions
- **CLI tools > MCP servers**: `gh`, `sentry-cli` etc. have zero context overhead
