 3. **Rebase onto main**: `git rebase origin/main`
 4. **Push branch**: `git push -u origin feature/branch-name`
 5. **Create PR**: `~/.claude/automation/gitea-pr.sh "PR Title" "Description"`
-6. **Merge with rebase** (after user approval):
-   ```bash
-   git checkout main && git rebase feature/branch-name && git push

+6. **Merge** (after user approval): `~/.claude/automation/gitea-merge.sh`
+   - Rebases onto main and pushes
+   - Deletes local and remote branch
+   - Closes PR via API
 
 Notes:
-- Use rebase, not merge commits
-- Stash uncommitted state files before switching branches
-- Delete feature branches after merge
 - Gitea token stored at `~/.config/gitea-token`
-- PRs show as "closed" (not "merged") after rebase - expected
