shellbrain skillA
shellbrain is agent-read markdown (skill) from cucupac/shellbrain: Use when an agent should remember to ask Shellbrain for targeted recall at task start, subproblem changes, repeated failures, hypothesis changes, or closeout..
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 cucupac/shellbrain/shellbrain@git:20260714.47ac030mdr add cucupac/shellbrain/shellbrain@sha256:c28a4e7a0c3edeb5Pin 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.
