The body is lean and assumes Claude's competence — it gives concrete HTML tag formats, JSON payloads, and decision tables without explaining what Feishu or Markdown are. Only minor redundancy exists (the final 工具组合 table restates tools already introduced inline), which does not push it down to the 'mostly efficient but includes some unnecessary explanation' anchor.

Provides fully executable, copy-paste-ready guidance: exact media HTML tags, a complete feishu_doc_media download JSON payload, a wiki-node query payload, and an obj_type → tool → parameter decision table with a worked example. This matches the 'fully executable code/commands; copy-paste ready' anchor.

The Wiki URL workflow is clearly sequenced (query feishu_wiki_space_node → read obj_type/obj_token → route to the matching tool) with explicit branching including an 'unsupported type' fallback and a worked example. Since this is a read-only fetch operation, the destructive/batch feedback-loop cap does not apply, and the obj_type routing serves as an explicit checkpoint.

The skill is under 50 lines, single-purpose, and has no external bundle files (references/scripts/assets are absent). Per the rubric's simple-skills note, well-organized sections alone justify a 3 here, and the sections (媒体处理, 参数, Wiki 处理策略, 工具组合) are clearly organized.

Names the domain (Feishu cloud docs) and lists multiple concrete actions — '获取飞书云文档内容', '返回文档的 Markdown 内容', '支持处理文档中的图片、文件和画板'. This matches the 'lists multiple specific concrete actions' anchor rather than score 2's partial coverage.

Clearly states what the skill does, but the 'when' is only implied — there is no 'Use when...' clause. Per the rubric guideline, a missing explicit trigger clause caps completeness at 2.

Contains relevant domain keywords ('飞书云文档', '文档', '图片/文件/画板') but reads as tool-function jargon rather than natural user phrasing and lacks common variations. Not score 1 (it has real domain keywords) nor score 3 (no broad coverage of terms users would naturally say).

Targets a specific niche (Feishu cloud documents and their media handling) with distinct triggers unlikely to overlap with other skills. Not score 2, which would describe a more generic 'works with document files' scope.
