skill-rollback skillA
skill-rollback is agent-read markdown (skill) from nyldn/claude-octopus: Roll back to a previous checkpoint via git — use when a change went wrong and you need to revert.
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 nyldn/claude-octopus/skill-rollback@git:20260813.14437aemdr add nyldn/claude-octopus/skill-rollback@sha256:9da76e229763ec8dPin 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.
