# AI Evals Black-box benchmark cases for the Windmill AI generation modes (`flow`, `app`, `script`, `cli`, `global`). **Authoring and running cases is documented in the `ai-evals` skill** — load it before adding/changing a case or running a benchmark. Claude Code reads `.claude/skills/ai-evals/SKILL.md`; Codex and Pi read `.agents/skills/ai-evals/SKILL.md` (same canonical file). Invoke with `/ai-evals` in Claude Code, `$ai-evals` in Codex, or `pi --skill ai-evals`. For AI chat / copilot changes that these evals measure, see the `ai-chat` skill. The full case format, fields, and fixture details remain in `ai_evals/README.md`.
