This looks like a legitimate local security scanner, but its reports can include secrets it finds and the documentation understates some higher-risk modes.
Install only if you are comfortable with a local tool reading the skill directories you point it at. Treat generated JSON or Markdown reports as sensitive because they may contain real secrets; redact them before sharing or uploading. Prefer targeted local scans, avoid enabling any future auto-scan, URL-scan, dynamic-analysis, or auto-fix behavior until the tool clearly documents scope, isolation, redaction, and rollback behavior.
