+Put the same JSON as above in `~/.grok/hooks/clickfix-guard.json`, with `--harness grok`. Hooks in `~/.grok/hooks/` are always trusted, so there is no trust step. Check with `grok inspect`: it lists two `matcher=Bash` hooks. Grok also reads the hooks in `~/.claude/settings.json` and can discover Claude plugins; those routes are not live-tested, the explicit file is.

 ## Allowlist
 
-Official installers that are meant to be piped into a shell (Homebrew, rustup, uv) are in [`allowlist.default`](allowlist.default). The allowlist never allows anything on its own: it turns a refusal into a question for you. So it only matters where the agent can ask (Claude Code, Grok). Codex has no ask, so there allowlisted installers are refused like everything else; run them yourself. `CLICKFIX_GUARD=block` ignores the allowlist. Add your own in `~/.config/clickfix-guard/allow.txt`:
