Proof1 independent outlet
Key points
- Fuad Ali uses the Wonder Toys assistant to show how a production failure can become a complete improvement loop: collect the trace, investigate the code, propose a fix and test it against the cases that failed.
- The example starts with an application built on the OpenAI Agents SDK and instrumented with Arize.
- Arize skills provide a more direct route from a coding agent to traces, datasets and evaluators.
- Agent experiments replay failure datasets against a deployed development endpoint and compare quality, latency and cost before a change ships.
