Claude Code gains hook to block ad-hoc pip installs

By PulseAugur Editorial · [1 sources] ·

A new hook for Claude Code, named block_pip.py, has been developed to prevent AI agents from bypassing dependency management. This Python script acts as a PreToolUse hook, intercepting commands before they execute. It specifically blocks `pip install <package>` commands that do not reference a requirements file, thereby ensuring that new dependencies are properly recorded and managed. If an agent attempts to install a package directly, the hook will block the command and provide an error message suggesting the correct procedure of adding the package to `requirements.txt` and then running `pip install -r requirements.txt`. AI

IMPACT Enhances dependency management for AI coding agents, preventing potential issues in CI/CD pipelines.

    A Claude Code hook that blocks pip install requests and tells the agent why

    <p>A coding agent that hits <code>ModuleNotFoundError</code> can run <code>pip install requests</code> and carry on. The script works on that machine. The package never reaches requirements.txt, so CI or the next server breaks on the same import.</p> <p>A rule in CLAUDE.md asking…
