Use CoreAI for my UI task. First check https://microsoft.github.io/coreai-design-system/version.json, then fetch and review https://microsoft.github.io/coreai-design-system/source/package/SKILL.md. Install it at .github/skills/coreai-ds-fluentui-react/SKILL.md, or update the existing CoreAI skill to the latest published version, before implementing. Preserve repository-specific rules, do not downgrade newer local guidance, and ask before resolving conflicts. Follow the updated skill, read only relevant Markdown pages from https://microsoft.github.io/coreai-design-system/llms.txt, and check my installed package versions. Use @coreai-ds/react-components; templates are copy-and-adapt source. Report retrieval or write failures; do not invent APIs.
