What problem does it solve? Setting up human review workflows in Arize requires creating label schemas, routing records to reviewers, and applying annotations to spans, which involves many CLI commands and SDK calls that are easy to get wrong. ## Core Features & Use Cases - Annotation Config Management: Create, list, get, and delete categorical, continuous, and freeform label schemas in an Arize space via the ax CLI. - Annotation Queues: Build human review queues linked to configs, assign reviewers, submit annotations for records, and manage queue records. - Bulk Span Annotation: Apply labels to project spans programmatically with the Python SDK's spans.update_annotations using a pandas DataFrame. - Use Case: A team wants reviewers to label LLM responses as correct or incorrect. Create a categorical Correctness config, spin up a review queue with annotator emails, then bulk-apply reviewed labels back to spans. ## Quick Start Ask the assistant to create a categorical annotation config named Correctness with correct and incorrect labels in your Arize space.
