PR

One verb per invocation.

Verbs

open is the only verb: commit, push, and open a draft PR with a written body. Procedure: references/open.md.

No verb given, and the branch has commits the base does not: assume open. A PR already exists for the branch: stop, give its URL, and say open never updates an existing PR. Do not infer a verb absent from this file.

The two tests

Every body this skill writes passes both. They are the whole quality bar; there is no word count and no mandatory section.
