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 yêu cầu mô tả dài 1–2 câu cho skill docs-sandpack, nhưng không nêu tệp hoặc mục siêu dữ liệu nào. Xác định định nghĩa của skill trong repository, thêm mô tả nếu phù hợp và kiểm tra rằng skill hiện đã có mô tả có thể được phát hiện.
