将原始素材逐段打磨成完整文章，输出独立稿件。

把一堆原始素材（从碎片清单到转录稿）逐段打磨成一篇完整、独立的文章：通读原稿后按段落重写、润色并调整结构，输出可直接发布的成品稿件。当你有内容但需要把它做成正式文章时用。流程强调先读全稿再动笔，属于把内容“成形”的环节。

<what-to-do>

The user has passed (or will pass) a markdown file of raw material. Treat it as the input pile — anything from a tidy list of fragments to a wall of unstructured prose to a transcript. The format does not matter. Read it end-to-end before doing anything else.

Then run a shaping session that produces a separate article document. This is **exploit**: the exploring is done, the pile is fixed — commit to a structure and mine the pile to fill it. Do not edit the raw material file — it is read-only to this skill.

If the user did not say where to save the article, ask once and remember the path.
