What it does
A text-space optimizer from Microsoft that trains reusable natural-language skills for LLM agents without changing model weights. It edits a skill based on agent trajectories, accepts changes only when they pass validation, and outputs a best_skill.md file you can deploy.
Use cases
- 01Improve an existing skill using recorded agent runs
- 02Accept skill edits only when validation results hold up
- 03Export the best version of a skill as a markdown file
