arc skillA
arc is agent-read markdown (skill) from broomva/skills: Use when the user is handing over an unattended run and will not be there to answer: they are going to bed, stepping away, or leaving it overnight, and they want the work carried to an end state that is both finished and clean rather than to a stopping point. Symptoms: "I'm off until morning", "nobody is watching this tonight", "don't hand it back until it's merged", "decide what you need to decide without me", "clean up after yourself when it lands", "leave nothing of yours behind", or a recurr.
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 broomva/skills/arc@git:20260907.b9abd4amdr add broomva/skills/arc@sha256:f9dd673b03cde435Pin 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.
