using-groundwork is agent-read markdown (skill) from etr/groundwork: This skill should be used when starting any conversation - establishes how to find and use skills, requiring Skill tool invocation before ANY response including clarifying questions.

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.
