# Fluent UI

One of the two deepest builder-side stacks in the survey — nine executable skills, never-violate rules, lint auto-fix loops, visual verification — behind almost nothing for consumers.

## Edges

- holds -> Gate the task. Make the agent call a tool, run a CLI, pass a validator., The agent-facing file is policy writing, and reads like a rulebook rather than documentation.
- maintained_by -> Microsoft
- ships -> Agent skills, Prohibition rules, Validation loops
