# Feedback Definitions

Feedback definitions allow you to create custom labels to systematically collect and analyze structured feedback on your LLM outputs.

## Using Feedback Definitions

Once created, feedback definitions appear in two places:

1. **Trace and thread sidebars** — Add scores when reviewing individual items.
2. **Annotation queues** — Pick which definitions annotators see when you create a queue.

You can also log feedback scores programmatically using the SDK. See the [SDK documentation](/guides/rest-api-overview) for details.
