perfeval-agent skillA

perfeval-agent is agent-read markdown (skill) from stempeck/agentfactory: Evaluate any agentfactory agent's runtime performance from telemetry and session transcripts, walking time down through child agents to the true consumer, and produce ONE evidence-backed highest-impact optimization with verbatim reproduction queries. Use when the user says "/perfeval-agent <agent>", "evaluate performance of <agent>", "why is <agent> slow", "where does the time go", or "find the slow steps". Ends by offering /github-issue for the finding — it never auto-files..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
