checkpoint skillA
checkpoint is agent-read markdown (skill) from ariaxhan/kernel-claude: Save bounded progress as kernel.checkpoint/v1 for exact resume after reset. Triggers: checkpoint, save progress, context reset, compact soon, long task..
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 ariaxhan/kernel-claude/checkpoint@git:20260828.e3ca514mdr add ariaxhan/kernel-claude/checkpoint@sha256:ac40162296b1749dPin 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.
