Skill Security Auditor

Performs heuristic security reviews of Claude Code skill files to detect malicious commands, prompt injections, and scope violations.

Audit Skills safeguards development workflows by inspecting SKILL.md files for dangerous bash execution patterns, prompt injection phrases, unexpected credential access, and scope violations outside project boundaries. It verifies that a skill's actual instructions match its declared frontmatter description and establishes cryptographic provenance baselines (SHA-256) for third-party or adopted skills to flag silent modifications. Designed intentionally to never auto-fix or auto-trust code, this tool delivers clear, structured vulnerability reports so teams can safely evaluate agent capabilities before execution.
