Commit and push

Use this skill only for an explicit request to commit and push. Inspect status and both diffs first, stage requested paths explicitly, and stop when there is nothing to commit. Preserve unrelated work. Use the Conventional Commit format described by commit; read coauthor-attribution.md only when a trailer is requested.

Before committing, verify that HEAD names a branch, origin exists, and the requested branch is safe to publish. Never push a detached HEAD or directly push a protected integration branch (main, master, develop, or production) unless the user has explicitly named that branch and repository policy permits it. Commit locally first, then push the exact branch; use git push --set-upstream origin "$BRANCH" only when no upstream exists. A rejected push is a reportable failure: do not force-push, amend, or retry with another remote. Report commit hash, branch, remote, and push result.
