sdd-derive skillA

sdd-derive is agent-read markdown (skill) from ahgraber/skills: Use when deriving SDD specs from existing code or retroactively documenting implemented behavior. Triggers: "derive specs", "generate specs from code", "document this code in SDD", "retrofit specs", "spec out what's already built"..

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

Latest version
mdr add ahgraber/skills/sdd-derive@git:20260910.5fa2be4
Exact content
mdr add ahgraber/skills/sdd-derive@sha256:bd9a92a960d2a442

Pin 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.
