spec-probe skillA

spec-probe is agent-read markdown (skill) from ucsandman/claude-skills: Run before implementing anything non-trivial: surface omitted edge cases and must-NOT constraints into a verification-tiered TASK_CONTRACT.md, so the verifier has something to check against. Use when starting a feature, a bugfix with unclear intended behavior, or any task where a reviewer would have to guess what correct means. Also use when asked to spec-probe, write a task contract, or check what the spec left out..

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

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.
