# Caveman

> Auto-activation works differently per agent: Claude Code uses SessionStart hooks, this repo's Codex dogfood setup uses .codex/hooks.json, Gemini uses context files. Cursor/Windsurf/Cline/Copilot can be made always-on, but npx skills add installs only the skill, not the repo rule/instruction files. ¹ Codex uses $caveman syntax, not /caveman. This repo ships .codex/hooks.json, so caveman auto-starts when you run Codex inside this repo. The installed plugin itself gives you $caveman; copy the same
