The body is a short numbered list with a closing caveat and no padding or explanation of concepts Claude already knows — '先列出用户指定的工作区图片与用途' and '只调用 upload-cover-image 或 upload-article-image' are lean and every line earns its place, matching the 'lean and efficient; assumes Claude's competence' anchor; not a 2 because there is no unnecessary explanation to tighten.

It names concrete tools ('upload-cover-image', 'upload-article-image') and expected outputs ('media ID 或正文图片 URL'), which is more concrete than pure description, but it gives no executable call signatures or argument detail, fitting the 'some concrete guidance but incomplete; missing key details' anchor; not a 3 because it is not copy-paste ready, not a 1 because specific tool names and return values are present.

The four-step numbered sequence includes an explicit checkpoint in step 4 ('图片不适合...先提示用户处理，不要擅自上传') plus the caveat '上传图片不等于发布文章', giving a clear sequence with an explicit decision/escalation step; for this simple single-task skill this meets the level-3 'clear sequence with explicit validation steps' anchor.

This is a simple skill under 50 lines with no need for external references (no references/, scripts/, or assets/ bundle exists), and the content is well-organized as a numbered list with a closing caveat; per the simple-skills guideline, well-organized sections with no required external files score 3.

Quotes 'Prepare selected workspace images and information cards as WeChat Official Account cover and article assets' — it names the domain and concrete objects (cover, article assets, information cards) but relies on the single general verb 'Prepare' rather than listing multiple specific actions, matching the 'names domain and some actions, but not comprehensive' anchor; not a 3 because no enumerated set of distinct actions, not a 1 because the domain and targets are concrete.

It states what the skill does ('Prepare... as WeChat Official Account cover and article assets') but has no explicit 'Use when...' trigger clause, so 'when' is only implied; per the judging guidelines a missing explicit trigger clause caps completeness at 2.

Terms like 'WeChat Official Account', 'cover', 'article assets', 'information cards' are natural and relevant, but common variations a user might say (e.g. '公众号', 'media ID', 'cover image') are absent, fitting the 'some relevant keywords but missing common variations' anchor rather than the full-coverage level 3.

'WeChat Official Account cover and article assets' with the constraint 'without reading outside the active workspace' defines a clear niche tied to specific upload operations, unlikely to trigger for unrelated skills, matching the 'clear niche with distinct triggers; unlikely to conflict' anchor.
