Caveman

plugin

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

Security audit

Not scanned yet. We audit npm-published capabilities for known advisories, install-time scripts and permission surface; this one has no npm package we can resolve, or has not reached the queue.

You searched for one. Check the rest of your stack:

npx tashan-cli doctor

Reads the config already on your machine and names what is dead, deprecated or running code at install time. No account, nothing uploaded.

Everything on this page is public evidence and free. What it cannot know is whether you run this — check your whole config, free, in the browser. tashan Pro adds the series behind each row and names a replacement for anything dying.

Already running this? Check your whole config — free, in your browser, nothing installed. Or npx tashan-cli doctor locally, which sends nothing at all.
