HookStack

Catalogue of installable guardrail hooks for Claude Code, OpenAI Codex, and GitHub Copilot

Pluginfree

HookStack is a catalogue of production-ready hooks that add guardrails to AI coding agents including Claude Code, OpenAI Codex, and GitHub Copilot. A single install command lets a developer pick hooks from a menu, and the CLI auto-detects the project and writes the needed scripts and config, keeping them updated over time. It is aimed at developers who want safety guardrails on their AI coding agent without hand-writing hook scripts.
