cad-spike skillA
cad-spike is agent-read markdown (skill) from crenshawdev/cadence: Spike - a time-boxed experiment resolving one unknown before you bet on it, risk-first, with a validated | invalidated | inconclusive verdict.
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 crenshawdev/cadence/cad-spike@git:20260805.6a63445mdr add crenshawdev/cadence/cad-spike@sha256:fdada8fc0104013cPin 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.
