My branches end up in a tree structure (no shit!), and I rebase and merge up stream as changes land. I guess it could be more automated, but the only tedious part is remembering to remove old worktrees and prune the old branches
worktree add: `git worktree add` that creates a local new branch and a directory with the same name and sets upstream to match; alternatively checks out an existing remote branch.
worktree rm: Removes worktree directory, first checking it is in porcelain state. Then prunes them and removes local branch pointers if they match the remote ones.
These all are handwritten and probably buggy, but still less prone to errors than typing out `git worktree add -b foo-123-fix-missing-semicolon foo-123-fix-missing-semicolon origin/develop` manually every time. One pass with Claude or Codex would probably do wonders.
