What problem does it solve? Finding accurate, up-to-date documentation for Microsoft Fluent UI v9 (@fluentui/react-components) is hard because props, slots, and tokens change every commit. This Skill routes the agent directly to the canonical source files in the microsoft/fluentui GitHub repository instead of relying on stale or mirrored docs. ## Core Features & Use Cases - Canonical API lookups: Reads auto-generated *.api.md files for exact prop, slot, and type signatures of any v9 component package. - Specs, migration guides, and examples: Fetches SPEC.md, MIGRATION.md, best-practices docs, and *.stories.tsx usage examples per component. - Design token resolution: Locates primitive tokens in @fluentui/tokens and semantic tokens in @fluentui/react-theme for use in makeStyles. - Use Case: When asked "What props does Dialog take?", the agent runs gh api against the react-dialog package's API report and returns the exact TypeScript signatures from the live upstream repo. ## Quick Start Ask the agent what props the Fluent UI v9 Dialog component accepts and have it fetch the answer from the microsoft/fluentui repository.
