Conciseness

The core usage sections are tight, but there is real padding: a dated changelog ("v1.0 (2025-12-24)") outside any deprecated/old-patterns section, a promotional author footer ("公众号「花叔」| 30万+粉丝"), and a 设计特点 section restating visual details already implemented in the script's CSS. This fits anchor 3 (mostly efficient, some unnecessary content) better than anchor 4, where only minor trimming would be needed.

Actionability

Primary guidance is copy-paste ready: "python scripts/convert.py input.md -o \"我的白皮书.pdf\"", "pip3 install markdown2 weasyprint", plus concrete heading-format rules ("## 1. 标题"). However, the 配置选项 section presents constants ("PRIMARY_COLOR = '#06c'", "COVER_TITLE_SIZE = '64pt'") that do not exist in scripts/convert.py — the values only appear inline in the embedded CSS — so following that guidance fails, keeping it below anchor 5.

Workflow Clarity

For a simple single-command skill the action is unambiguous (run convert.py with documented flags), and prerequisites are stated: heading format rules and dependency installation. It misses anchor 5 because the steps are not sequenced — 依赖安装 appears near the end after usage, FAQ, and examples — and there is no verify-output step (the missing-image warning behavior is documented but as a footnote).

Progressive Disclosure

The body is well-sectioned and references the real bundle file scripts/convert.py; the long macOS 乱码 known-issue deep-dive is arguably reference material but is operationally important inline. Minor gaps: 脚本说明 lists scripts/styles.css and templates/cover.html as entries even though those files don't exist on disk (they are embedded), which is a small navigation inaccuracy that keeps it from anchor 5.

Specificity

Lists several concrete actions — "将 Markdown 文档转换为专业的 PDF 白皮书", "自动生成封面、目录、页眉页脚", "支持完整的 Markdown 语法（代码块、表格、引用、列表等）" — which is specific and near-comprehensive for this task. It stops short of anchor 5 because capabilities like custom title/author output options are absent, and it is above anchor 3 since it goes beyond 1-2 actions.

Completeness

Answers both questions: the "what" via conversion features, and an explicit when-clause "使用场景：技术文档、白皮书、教程、报告等需要专业排版的 Markdown 文档". It is not capped at 3 because explicit trigger guidance is present, but it falls short of anchor 5's "concrete trigger phrases" — the when-clause lists document categories rather than phrases a user would actually say.

Trigger Term Quality

Contains natural terms a user would say: "Markdown", "PDF", "白皮书", "技术文档", "教程", "报告", "排版". Not anchor 5 because common variations and file extensions (".md", "md 文件", "导出 PDF") are missing, but coverage is clearly better than the partial synonym coverage of anchor 3.

Distinctiveness Conflict Risk

The niche (Markdown→styled PDF whitepaper, "采用苹果设计风格") is distinct with clear triggers; only minor overlap risk with generic document-conversion skills. Not anchor 5 because the trigger terms overlap somewhat with general PDF/document skills and no file-extension disambiguator is given.
