skill-sentinel

Security scanner and threat analyzer for AI agent skills. Activate this skill whenever a new skill is added to the workspace, when the user imports or installs a skill from an external source, when asked to audit or review an existing skill for safety, or when the user mentions scanning, vetting, checking, or validating a skill before use. Also trigger when the user references skill security, malicious code detection, prompt injection scanning, or supply chain safety for any SKILL.md file or skill directory. This skill reads all files within a target skill folder and produces a structured threat assessment with severity ratings and actionable recommendations.
