Agents Building Agents - Alfonso Graziano, Nearform

Alfonso Graziano, a tech lead at Nearform, presents a production workflow where a coding agent (Claude Code) builds and iteratively improves a target AI agent by running evals, inspecting failures, and autonomously fixing system prompts, tool contracts, or code. He demonstrates that this loop raised eval accuracy from 18% to 83% on a naive agent and achieved a 10% improvement on a human-optimized production agent. For live data, the system collects user feedback traces, clusters failure modes with root-cause analysis, and generates fix proposals, which are validated by subject matter experts and added to a golden dataset. The method relies on spectrum development, quality gates, and observability, enabling semi-autonomous agent improvement without cheating on eval sets.
