What it does

Give it every file of a skill you're thinking of installing. It compares what the skill claims to do with what its instructions and scripts actually do, checks for download-and-run commands, encoded text, requests for passwords or keys, unexpected network calls and instructions aimed at the reviewer, and gives a verdict: low risk, review needed, or do not install. Every finding quotes the file and line.

Good for

  • Anyone installing skills from public directories.
  • Teams that want a consistent first-pass review before a person signs off.

Before you install

Instructions only, plus a reference list of red flags. It never runs the skill it reviews. It's a first pass, not a security audit: it can't see inside binaries or code downloaded later.
