Name a git branch following the Conventional Branch spec (conventionalbranch.org): <type>/<short-description>, lowercase, hyphen-separated, optionally issue-numbered. Use whenever you are about to create a branch, are asked to start work or cut a branch for an issue, need help choosing a branch type or slug, or want to rename a branch that doesn't match the convention. If the repo defines its own branch convention (CONTRIBUTING.md, an established branch-naming style), follow that — this skill is the general baseline.
