using-superpowers skillA
using-superpowers is agent-read markdown (skill) from jdanigo/hydraia: Use when starting any conversation - establishes how to find and use skills, requiring skill 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.
How to install
mdr add jdanigo/hydraia/using-superpowers@git:20260702.9dc0119mdr add jdanigo/hydraia/using-superpowers@sha256:55379fe7c1c473a0Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
