Commit creation

Determine the action

• Message-only requests produce text. Implementation-only requests leave checked working-tree edits local and preserve staging.
• Commit, rewrite, or push only within matching user authorization. A commit request covers creation and needed staging, not rewriting or pushing. PR creation includes its task commits and push. Completed commit or publication requests do not cover later fixes unless a standing instruction does.

Inspect the changes

Base the message on the repository state, not conversation memory alone:

git status --short --branch
git diff --cached
git diff

Identify the concrete behavior, files, packages, issue references, and version changes that belong to the requested commit. If there is no substantive change, stop instead of inventing a message.
