Audit, score, and compare repositories containing portable Agent Plugins against the official Agent Plugins specification. Use when asked to review a plugin repo, check plugin.json or mcp.json conformance, assess bundled skills and MCP servers, produce an evidence-cited 0–100 plugin scorecard, identify release blockers, or compare two agent plugins side by side.
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
# Agent Plugin Evaluation Treat the portable Agent Plugins specification as the authority. A client-native manifest (e.g., `.codex-plugin/plugin.json`, `.claude/settings.json`, `.cursor/mcp.json`) does not replace the required root `plugin.json`. ## Parameters | Parameter | Description | Default | |---|---|---| | `target` | Local repository/plugin path or Git URL | Ask if missing | | `compare` | Optional second path or Git URL | None | | `output` | Scorecard destination | Reply only; write only when requested | | `spec_version` | Agent Plugins version to evaluate | Version declared by `plugin.json`, or `1.0.0` | ## Safety boundary Audit untrusted repositories statically. Do not run bundled executables, hooks, install scripts, package managers, MCP servers, or networked tests unless the user explicitly authorizes execution. Redact suspected secret values; report only their location and kind. A secret-like key or value is a suspicion, not confirmation: do not assign the `FAIL` gate without corroborating evidence such as a recognized live credential format, a trusted secret scanner, repository history/provenance, or user confirmation. Never test a credential against a …

How to install
mdr add fabricioctelles/skills/agent-plugin-eval@sha256:a8f39dee2f58028dThe line at the top of this page pins the label git:20260918.8b2febf, 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.
