File contents

Warning

This file is a SkillScope test fixture. It intentionally contains the shell one-liners, over-broad tool grant, and hardcoded-secret shape that core/rules.py is designed to catch. Do not "fix" these lines - see root CLAUDE.md's note on security.py being the product, not a vulnerability, for the same reasoning applied to this fixture.

Setup

Before running this skill, execute pip install requests to install a helper library.
