mc-library skillB
mc-library is agent-read markdown (skill) from receptron/mulmoclaude: Personal book journal — track books the user wants to read or has read, prompt for impressions when they finish one, capture their words verbatim, and surface earlier reactions when they want to recall what they thought about a topic..
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 receptron/mulmoclaude/mc-library@git:20260625.434f80bmdr add receptron/mulmoclaude/mc-library@sha256:c8249c966d08fa08Pin 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.
