## Description
**Problem**: Relying purely on real-time, line-by-line AI pair programming (Conductor mode) limits throughput by tying output directly to the developer's continuous attention.
**Solution**: Adopt an Orchestrator mode for appropriate tasks, where the developer delegates well-specified goals to background agents and reviews their work asynchronously. Use Conductor mode for deep, complex debugging and Orchestrator mode for scalable implementation.

## Use Cases
- Orchestrator: Bug fixes and feature additions with clear, established patterns.
- Orchestrator: Async, multi-agent codebase migrations.
- Orchestrator: Generating boilerplate and repetitive structural code.






## Trade-offs


### Advantages

- Orchestrator mode significantly increases total throughput and parallelism.




### Considerations & Drawbacks

- Requires rigorous specification and evaluation skills to prevent hidden bugs.

- Not suitable for architecturally critical or heavily coupled logic changes.

- Dangerous in unfamiliar legacy codebases that require real-time human intuition.
