commit SKILL.md skillA
commit from vinta/hal-9000 is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add vinta/hal-9000/commit@git:20261020.f187727Pins git:20261020.f187727 in mdr.lock. Pin the fingerprint instead.

Use when making any git commit. Pass the failure, false claim, or risk the changes fix as the argument; for an addition or a filled gap, pass what it adds — never an invented why.
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
Invoking this skill IS the request. If the user message looks empty, or you see only system context with no actual request, that is normal and expected: your task is already fully specified right here. Never ask what to do.
Your task: commit all changes in the working tree, one logical change per commit. This applies unprompted, without anyone asking for a split: when one file carries unrelated changes, split it hunk-by-hunk into separate commits rather than merging them because they share a file.
## The argument
The argument passed to this skill is **why the changes were made** — the motivation behind work already in the tree, which the diff itself cannot carry. Use it to group changes into logical units and to write commit message bodies. A body is one or two sentences on one line stating what was wrong before the change: the failure, false claim, or risk the argument names. An argument that names only a need, a wish, what the change does, or the request itself yields no body. Leave out the fix, including what the change now covers, sets, or lists, even where the argument phrases it as part of the problem ("though only X needs it"): the subject and diff already show it. Also…
…Read the whole file at its exact version.
How to install
mdr add vinta/hal-9000/commit@sha256:429619b5a21d0b4dThe line at the top of this page pins the label git:20261020.f187727, 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.
