Let Your Agent Cook: Using Skills to Evaluate and Improve Your App — Ankur Duggal, Arize AI

Let Your Agent Cook: Using Skills to Evaluate and Improve Your App — Ankur Duggal, Arize AI

A financial agent produces confident investment advice with fabricated details, redundant tool calls and bad summaries. This talk shows how traces, evaluations, and a coding agent connected through the Arize CLI and skills can investigate those failures, propose fixes, and test them with experiments. It covers why evaluations matter over vibes-based shipping, how judges and costs fit in, and why human review and application-specific evals are still essential.

Building Self-Learning Loops for Your Agent — Fuad Ali, Arize AI

Building Self-Learning Loops for Your Agent — Fuad Ali, Arize AI

Fuad Ali demonstrates how a production failure in a shopping agent, a price filter that ignores budget limits, can become a closed improvement loop. Arize Signal and Arize Skills detect and investigate the failure from traces and code, harness-based judges assess outcomes with tool access and external context, and agent experiments validate the proposed fix against real failing traces before it ships.

Evaluation-Driven Development with MLflow 3.0

Evaluation-Driven Development with MLflow 3.0

Yuki Watanabe from Databricks introduces Evaluation-Driven Development (EDD) as a critical methodology for building production-ready AI agents. This talk explores the five pillars of EDD and demonstrates how MLflow 3.0's new features—including one-line tracing, automated evaluation, human-in-the-loop feedback, and monitoring—provide a comprehensive toolkit to ensure agent quality and reliability.
