Microsoft Foundry launches Agent Optimizer to auto-refine prompts, tool descriptions and model picks
davemccollough · x · 2026-10-20
Microsoft's new agent optimizer in Foundry Agent Service automates the test-and-refine loop for building agents, replacing slow manual prompt iteration.
- What it improves: instructions, function-calling tool descriptions, and model selection for prompt agents; hosted agents additionally support skills optimization.
- How to run it: a no-code optimization wizard in the Foundry portal for prompt agents; Foundry Toolkit scaffolding for hosted agents.
- The evaluation-driven loop generates better configurations automatically so developers can focus on core agent logic. Useful for anyone building agents in the Microsoft ecosystem.
