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…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# arc The recurring operating mode of an unattended loop, as one word. Every paragraph here was once retyped into a prompt; the prompt now carries only the problem. `/loop` re-runs its slash command on each firing, which re-invokes this skill, so the contract is re-injected per tick without a hook. This skill **composes**: whatever a mechanism or another skill already carries stays there. `/autonomous` runs its reflexes. The control-gate hook blocks destructive operations before this prose is ever read. The fleet protocol is defined by bstack's Snapshot (P15) and Fanout (P5), given a mechanism by `bstack fleet` in 0.40.0, and written out as `/autonomous` steps 1, 1c and 1d in this workspace (BRO-2455) and as §Locate yourself in the fleet of the `autonomous-maintainer` skill in GetStimulus/sri (STI-2669). Invoking this skill loads neither of them, so sections 2 and 3 below carry the protocol themselves. What remains here is the part nothing else carried. ## Invocation ```bash /goal <condition> # typed by a person; this skill never proposes a goal (section 1) /loop 30m /arc # heartbeat: re-runs this skill every 30 minutes …

How to install
mdr add broomva/skills/arc@sha256:3765d0e6d3bc5333The line at the top of this page pins the label git:20261017.e8c7be7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
