写超大文件（预估或已知 >1000 行）时的防 socket 断开策略。用"骨架 + 哨兵 + 分片 Edit"避免单次 Write 触发 `socket connection was closed unexpectedly` / `API Error` / `Write failed`。任何涉及"写大文件"、"生成完整 HTML/Vue/Python 等长文件"、"一次性生成整个 xxxx.xxx"、"文件超过 1000 行"、"分片写"、"chunked write"、"socket closed"、"connection closed unexpectedly"、"write failed"、"写挂了重试" 的诉求（事前预防 / 事后补救），都必须通过本 skill 完成，不要直接 Write 整个长文件。

分片写大文件 skill。核心思路：单次 Write 的 content 越长，socket 越容易断。把长文件拆成「骨架 + 多次 Edit 追加」。
