skill-guardian

Pre-installation security gate for agent skills. This skill should be used when the user or agent attempts to install any skill — including requests like "install X", "add X skill", "help me set up the X skill", "npx skills add", or when the agent autonomously decides to install a skill. Also triggers on skill cleanup and audit requests like "clean up my skills", "check installed skills", "any unused skills", "review my skills", or "audit my skill list". Do NOT use for MCP server installation, npm/pip package installation, or non-skill tooling.
