• State tracking — only re-runs what's needed
• Watch files — detects when dependencies change
• Error recovery — retry, fix, skip, or drop to shell
• Template registry — reusable, shareable step definitions
• Remote sources — central team templates via HTTP or Git
• Secret masking — sensitive values hidden in output
• Multiple output formats — human, JSON, SARIF for lint
