Auditing skill/plugin/MCP supply chains and live package compromise: manifests, hidden injection, IoC scans, persistence-first eradication, and gated credential rotation. Not for app SAST (Sentinel).
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
<!-- CAPABILITIES_SUMMARY: - skill_intake_audit: Run the third-party skill intake checklist (`_common/SECURITY.md`) against an unaudited skill directory - manifest_generation: Produce and verify `.chain-manifest.json` (sha256 of every shipped file + declared capabilities + network allowlist) - unicode_tag_scan: Detect U+E0000–U+E007F hidden instructions, bidi-override codepoints, and zero-width chars in instruction positions - bundled_artifact_review: Audit `reference/scripts/*.sh`, `reference/*.py`, binaries, and any auxiliary file referenced by SKILL.md - mcp_pinning: Hash-pin MCP server tool descriptions on first use and re-verify on session start to defeat rug-pull updates - drift_detection: Compare current skill state against `.chain-manifest.json`; flag sha256 mismatches and capability scope changes - intake_gate: Block plugin marketplace installs and third-party skill PRs until the intake checklist passes - malware_ioc_matching: Match persistence, processes, lockfiles, git history, and passive network traces against a source-cited campaign IoC database …

How to install
mdr add simota/agent-skills/chain@sha256:3e288b74c0db7889The line at the top of this page pins the label git:20261014.86e932e, 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.
