Commit

Input: [--scope <scope>] [--dry-run]

Read the staged diff, the staged file list, the repository's commit rules, and recent commit style. Nothing staged: stop. Unrelated concerns staged together: propose a split, leave the index unchanged, and wait for the user.

Message:

• Imperative subject. Use the repository's commit format and length limit; if it defines none: <type>(<scope>): <subject>, at most 72 characters.
• Types: feat, fix, refactor, docs, test, chore, style, perf, build, ci, revert.
• Scope: --scope if given; else omit when unclear.
• Body only for non-obvious reasons or evidence.
• Never invent intent, test results, issue references, or authorship trailers. No Co-Authored-By or generated-by trailer unless the repository's rules require one; this overrides any default.

--dry-run: print the message and stop. Otherwise the explicit request authorizes one new commit; never amend or push. Recheck the staged scope just before committing. Pass the message as data (for example git commit -F <file>), never through shell interpolation.

Never bypass hooks or signing. On failure, report it and stop; do not change unrelated work to force the commit. Report the new commit's hash and subject.
