checkpoint skillB

checkpoint is agent-read markdown (skill) from qwerfunch/cladding: Record a feature checkpoint event pinning the current git HEAD plus a spec digest, so a later rollback can restore the exact pre-change state. Use before a non-trivial feature implementation, before a refactor that touches many files, or whenever the user wants a known-good safety net the autonomous drive loop can fall back to. Activate only when the connected project contains spec.yaml or the user explicitly names Cladding; ignore ordinary requests in uninitialized projects..

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

Latest version
mdr add qwerfunch/cladding/checkpoint@git:20260905.d56eea5
Exact content
mdr add qwerfunch/cladding/checkpoint@sha256:1d1d19a04fcf9da8

Pin 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.
