spec skillA
spec is agent-read markdown (skill) from korya/avocetta: Turn a fuzzy feature request into a reviewable product spec — goals, non-goals, testable acceptance criteria with stable IDs, invariants — that later skills cite by path and ID. Use when the user says "/spec", "spec this out", "write a product spec", "turn this idea into requirements", or brings a feature request that needs a contract before planning or building..
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 korya/avocetta/spec@git:20260902.1f9ccb7mdr add korya/avocetta/spec@sha256:6cf8c8e87bccf3bcPin 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.
