Add a description to improve Dispatch discoverability

Hi! Your Claude Code skill docs-sandpack has been discovered by Dispatch — a Claude Code runtime that proactively recommends tools at task shifts and intercepts when Claude picks something suboptimal — helping developers discover the best plugins, skills, and MCPs for what they're working on.

Right now your skill has no description, which limits how effectively Dispatch can recommend it. A short 1–2 sentence description of what your skill does would significantly improve its visibility.

Feel free to close this if you'd prefer not to add one — no action required. We reach out at most once per month per repository.

— The Dispatch team

Issue では docs-sandpack skill の 1～2 文の説明が求められていますが、ファイルもメタデータエントリも指定されていません。リポジトリ内で skill の定義を見つけ、適切であれば説明を追加し、skill に説明が設定されて検出可能になったことを確認してください。
