## Risk Mitigation

| Risk | Mitigation |
|------|------------|
| **Breaking changes to existing setups** | Test changes in isolated branch first |
| **Pre-commit hooks too slow** | Make them optional (CI enforces) |
| **IDE configs conflict with personal prefs** | Use workspace settings (don't override user) |
| **Resistance to new workflows** | Document benefits, make adoption gradual |
| **Maintenance overhead** | Automate where possible (Dependabot, CI) |
