skill-without-sidecar skillB
skill-without-sidecar is agent-read markdown (skill) from coalesce-labs/catalyst: A fixture skill with no neutral classification — legal, but cannot reach a non-Claude target..
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 coalesce-labs/catalyst/skill-without-sidecar@git:20260826.5f4fa48mdr add coalesce-labs/catalyst/skill-without-sidecar@sha256:c6d444bead2ae486Pin 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.
