Producer-Critic Pattern(PC)
Architectural pattern where separate producer and critic agents collaborate for quality improvement
In 30 seconds
- What
- One agent generates output while a separate agent evaluates it and returns structured feedback, repeating until quality thresholds are met.
- When to use
- Work requiring iterative refinement where independent evaluation prevents the producer from reinforcing its own mistakes.
- Watch out
- Critic and producer can enter unproductive loops if feedback is vague, contradictory, or the producer lacks clear improvement paths.
