| 1 | Dry run before apply in production | CRITICAL | kubectl_apply(dry_run=True) |
| 2 | Check current state before patching | HIGH | describe_* tools |
| 3 | Avoid force delete unless necessary | HIGH | kubectl_delete |
| 4 | Verify rollout status after changes | MEDIUM | kubectl_rollout_status |
