Review agent skills before installation or use. Use when a user or security team wants to check a skill file, bundle, or collection for unsafe instructions, scripts, permissions, or external dependencies.
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
# Check agent skills Give the user a read-only, pre-install security review of the supplied skill. Return the decision and evidence directly in chat. This workflow does not require the Codex Security MCP server or a saved repository scan. ## Establish the target - Review from a trusted workspace. If the session started inside the target checkout or the target is installed or discoverable as a skill in this session, stop before inspecting it. Ask the user to start a clean session in a trusted workspace, keep the target outside the host's skill discovery paths, and supply it by external path. The host may already have loaded the checkout's `AGENTS.md` or `.agents/skills`, including a replacement `check-skills`. - Accept a local file, an extracted skill folder, a collection (including a repository checkout), or skill text pasted or attached by the user. If no target is identifiable, ask for it. …

How to install
mdr add devantler-tech/agent-plugins/check-skills@sha256:5c1196ca1f6377e7The line at the top of this page pins the label git:20261104.5e3cd8e, 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.
