oak

Work with repositories version-controlled by Oak (the `oak` CLI from oak.space) — a git replacement built for coding agents. Use this skill for ANY version-control operation (status, diff, commit, branch, push, pull, merge, clone, log, worktree-style parallel tasks) in a repo tracked by Oak. An Oak repo has a `.oak/` directory and NO `.git` — if `.git` is missing but `.oak/` exists, git commands will fail or corrupt state; use `oak` instead. Also use whenever the user mentions Oak, oak.space, `oak mount`, an "Oak space", or a virtual branch, and when finishing/publishing agent work in such a repo.
