Conciseness

Noticeably verbose: each role carries a '角色定位' paragraph restating generic assistant capabilities Claude already knows — e.g. '不断学习和更新自己的知识，以适应不断变化的信息需求', '我是一个可靠、高效、专业的助手，随时为用户提供帮助' — and 角色一's seven '核心能力' bullets are pure persona filler unrelated to PPT generation. This matches the 2 anchor ('several unnecessary explanations or padded sections'); it is not a 1 because the operational steps, commands, and resource index are themselves tight and useful.

Actionability

Provides an executable, complete command ('python scripts/generate_pptx.py --input ./ppt_data.json --output ./presentation.pptx'), concrete quantitative constraints (titles ≤ 20 chars, 3-5 bullet points per page, 10-20 pages), and per-role deliverables. Minor gaps — no inline example of the ppt_data.json structure (delegated to the reference) — keep it at anchor 4 rather than the copy-paste-ready 5.

Workflow Clarity

The seven-role pipeline is clearly sequenced, and alternate modes (optimize existing PPT, quick mode, content-fill mode, single-role branches) plus user-confirmation checkpoints ('输出初步大纲供用户确认', '在关键节点（如大纲确认）征求反馈') are explicit. Not a 5 because the final build step ends with '确认文件生成成功，告知用户' without an explicit validate-on-failure/fix/retry feedback loop, and redundant '可选分支' restates modes already defined above.

Progressive Disclosure

The body is a genuine overview that pushes details to a well-organized bundle: a '资源索引' section lists references/ppt_structure_guide.md, references/visual_design_guide.md, scripts/generate_pptx.py, and assets/ppt_templates/ (all verified to exist), each with a '何时读取' (when to read) annotation, and the same files are linked contextually at the exact role steps that need them. References are one level deep and clearly signaled, matching the 5 anchor.

Specificity

Lists several concrete actions — '自动分析主题、推荐模板、填充内容并智能配图，一键输出高质量 PPTX 文件' — alongside target users and contexts. It falls short of the 5 anchor because the optimization/polishing capability present in the skill body is omitted, and phrases like '一键输出高质量' carry mild promotional filler; it is clearly above anchor 3 (1-2 concrete actions) with five distinct named actions.

Completeness

The 'what' is explicit (analyze theme, recommend template, fill content, place images, output PPTX) and a genuine 'when' clause exists — '在准备商业演示、学术汇报或培训课件时' — so both are present. The 'when' is phrased as user-persona context rather than an explicit 'Use when the user needs...' trigger, which keeps it at anchor 4 ('when' could be more explicit) rather than 5, and it is well above anchor 3 where 'when' is only weakly implied.

Trigger Term Quality

Good natural keyword coverage: 'PPT', 'PPTX 文件', '商业演示', '学术汇报', '培训课件', '排版制作'. A few common synonyms users would say are missing ('幻灯片', 'PowerPoint', 'slides', '美化/优化 PPT'), placing it at the 4 anchor rather than the comprehensive 5, but well above the 3 anchor's 'missing common variations'.

Distinctiveness Conflict Risk

A clear niche (PPT generation via a seven-role workflow) with distinctive terms like '七角色协作工作流' and '智能配图'. Minor overlap risk remains with a generic presentation/.pptx manipulation skill, matching anchor 4 ('mostly distinct; minor overlap risk with closely related skills') rather than the 5 anchor's 'minimal conflict risk'.
