The body is lean and assumes Claude's competence — it never explains what Feishu, Markdown, or HTML are, and every section (media handling, params, wiki strategy, tool table) earns its place.

It provides exact HTML tag formats with token attributes, copy-ready JSON payloads for feishu_doc_media and feishu_wiki_space_node, an obj_type→tool decision table, and a worked example — fully executable guidance.

The wiki-URL flow is a clear numbered sequence with an explicit verify-before-act gate ('不能直接假设是云文档，必须先查询实际类型') and a fallback for unsupported types; the media-fetch flow is likewise clearly sequenced.

With no bundle files present, the single SKILL.md is well-organized into clear sections with no nested references or monolithic wall of text, satisfying the simple-skill allowance for progressive disclosure.

The description lists concrete actions — '返回文档的 Markdown 内容' and '支持处理文档中的图片、文件和画板' — enumerating multiple specific capabilities beyond merely naming the domain.

It clearly answers what the skill does, but provides no 'Use when...' clause or equivalent explicit trigger guidance, capping completeness at 2 per the rubric guideline.

'飞书云文档' is a relevant natural term, but the description relies on technical tokens (feishu_doc_media, Markdown, 画板) and omits common natural variations like '读取/查看文档' or '知识库/wiki', which only appear in the examples block.

Scoped specifically to Feishu cloud documents and the feishu_doc_media companion tool, giving it a clear niche unlikely to trigger for unrelated skills.
