AI / CrewAI Interview Questions
What is the @human_feedback decorator in CrewAI Flows?
The @human_feedback decorator pauses a Flow's execution at a specific point and waits for human input before continuing.
- Keeps the Flow's state persisted while waiting, rather than losing progress during the pause
- Supports approval workflows, quality review gates, and exception handling that requires a human decision
- Lets a mostly autonomous Flow still route its riskiest or most ambiguous decisions to a person
This is CrewAI's equivalent of a human-in-the-loop checkpoint, built directly into the Flow's execution model rather than bolted on separately.
