Audit third-party AI agent skills before installation with SkillPreflight's local static scanner. Use when a user asks whether a Codex, Claude Code, Cursor, Gemini CLI, or other SKILL.md bundle is safe, lightweight, token-efficient, trustworthy, or suitable to install; when reviewing a skill URL or local path; or before running a skill installer.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# SkillPreflight Inspect an agent skill before installing it. Use the published SkillPreflight CLI to read the target without executing its scripts. ## Workflow 1. Identify the exact local directory, GitHub repository, GitHub skill directory, or `SKILL.md` URL the user wants to inspect. 2. Scan before running any installer, setup command, dependency script, or executable from the target. 3. Prefer JSON output so scores, categories, findings, and metrics remain structured. 4. Review critical and high findings independently of the overall score. 5. Present the evidence and ask for explicit confirmation before proceeding with an installation. ## Run The Scan Confirm that Node.js 20 or newer is available: ```bash node --version ``` Scan one skill: ```bash npx --yes skill-preflight@latest scan <target> --format json ``` For a repository containing many skills, inspect the lowest-scoring entries first: ```bash npx --yes skill-preflight@latest scan <target> --summary --top 20 --format json ``` Then run a full scan against the specific skill directory selected for installation. …

How to install
mdr add agent-contracts/skill-preflight/skill-preflight@sha256:259d76cc82c0b9f1The line at the top of this page pins the label git:20260901.61b6679, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
