- Document that dev is the default working branch
- main is reserved for stable/production merges only

+## Git branch policy

+- **Default working branch:** `dev` — all commits and pushes target `dev` unless the user explicitly requests otherwise.
+- `main` is the stable/production branch; merge to `main` only when explicitly instructed.
+- After committing, push to `origin/dev`.
+- If `dev` does not exist locally, create it from `main` or fetch it from origin.
+
 ## Git workflow
 
-### Branching strategy
-
-For every spec change or new functionality:
-
-1. Create a new branch from `dev` with a proper prefix:
-   - `feat/` for new features (e.g., `feat/tool-workshop`)
-   - `fix/` for bug fixes (e.g., `fix/terminal-tty`)
-   - `refactor/` for refactors (e.g., `refactor/api-cleanup`)
-   - `docs/` for documentation (e.g., `docs/api-guide`)
-   - `chore/` for maintenance (e.g., `chore/update-deps`)
-2. Branch name should reference the OpenSpec change name when applicable.
-3. Do not commit directly to `main` or `dev`.
-
-### Completion and merge
-
-When implementation is complete and verified:
-
-1. Ensure all tests pass and quality gates are met.
-2. Stage all changes with `git add -A`.
-3. Create a commit with a proper conventional commit message (see below).
-4. Switch to `dev`: `git checkout dev`.
-5. Merge the feature branch: `git merge --no-ff <branch-name>`.
-6. Push to remote: `git push origin dev`.
-7. Delete the local feature branch if desired: `git branch -d <branch-name>`.
