+## Worktree And PR Workflow
+
+- For any code or documentation change, do not edit the main checkout directly unless the user explicitly asks for it.
+- Create a new git worktree from the repository default branch and work on a dedicated `codex/...` branch.
+- Keep the main checkout clean. If changes accidentally land there, move them into a feature worktree before continuing.
+- Stage only the intended files, commit the scoped change, push the branch, and open a draft pull request.
+- Run the most relevant available checks before opening the pull request, and mention any checks that could not be run.
+- Do not overwrite, reset, or include unrelated local/user changes from other worktrees.
