Conciseness

The body is dense and prescriptive — tables of parameters, hex palettes, prompt templates, naming rules — with no explanations of concepts Claude already knows. Minor trim candidates: the author-bio footer ("花叔出品 | 公众号「花叔」| 30万+粉丝...") is irrelevant to execution, and the "Golden Rules" section restates points already made in the aesthetic profile. Not 5 because of that padding; not 3 since the padding is minor.

Actionability

Fully concrete commands ("uv run .../generate_image.py --resolution 2K", "npx playwright screenshot ... --viewport-size=1080,1440"), a complete prompt template, and exact file-naming rules. Falls short of 5 because the commands embed machine-specific absolute paths ("/Users/alchain/Documents/写作/...") and rely on the macOS-only `open` command, so they are not copy-paste ready outside the author's machine. Above 3 because the commands are real and complete, not pseudocode.

Workflow Clarity

A clearly sequenced 5-step flow (理解内容 → 设计提案 → 生成 → 预览确认 → 上传) with a mandatory user-selection gate ("这是整个流程最关键的一步。禁止跳过"), an explicit 4-item validation checklist (Chinese text rendering, 3:4 ratio, style match, no watermark), a two-dimension scoring review, and per-failure feedback loops ("文字有误 → 该张改用HTML兜底渲染", "大改方向 → 回到Step 2重新提案").

Progressive Disclosure

The body serves as a workflow overview with well-signaled one-level-deep references ("references/style-gallery.md — 完整风格库与 prompt 模板", "references/design-guidelines.md — 小红书平台设计规范") — both files exist and contain the promised content — plus a bundled script. Not 5 because the inline "快速参考" section (color palettes, prompt keywords) duplicates content that belongs in the reference files, keeping the split from being fully clean.

Specificity

"为小红书笔记生成高质量配图" names the action, and "默认AI生成（Gemini）" / "仅精确数据表格用HTML兜底" add two concrete method details, but the broader capability set (design proposals, review, upload) is not mentioned — matching 'names domain and 1-2 concrete actions' rather than the several-action coverage of level 4.

Completeness

Explicitly answers both what ("生成高质量配图"， with AI-default and HTML-fallback methods) and when ("当用户提到...时使用此技能") with concrete trigger phrases, matching the level-5 anchor structure exactly; level 4 would require the 'when' to be less explicit, which it is not.

Trigger Term Quality

Five explicit natural trigger phrases ("小红书配图", "小红书封面", "小红书图片", "做张小红书图", "笔记配图") including the very colloquial "做张小红书图" — comprehensive synonym coverage of what a user would actually say; no file extensions are relevant to this domain.

Distinctiveness Conflict Risk

Every trigger phrase is 小红书-specific, establishing a clear niche with minimal conflict risk even against the related wechat-image and image-to-slides skills named in the body.
