Conciseness

The body is directive rather than explanatory — it never explains what SVG, Mermaid, TAM/SAM/SOM, or SaaS are, and assumes Claude's competence throughout. However, the 10-item '质量检查清单' substantially restates requirements already stated in the phases (e.g., 'SVG 图表已单独保存并在报告中引用' repeats Phase 2's rule), and the emoji-decorated role roster duplicates the role list that lives in references/role-templates.md. These are minor instances of repetition that could be trimmed, matching the 4 anchor rather than the every-token-earns-its-place 5 anchor.

Actionability

For an instruction-only skill the guidance is copy-paste ready: literal search query templates ('搜索 `[产品名] review site:g2.com OR site:producthunt.com`', '`[产品名] funding crunchbase`'), exact output file names (markdown/01_user.md … 07_partner.md), a concrete required-information checklist, a fully specified directory tree, and fill-in-the-blank formats for KPA entries and 如果…那么… adjustment statements. Per the code_vs_instruction note, absence of code is not penalized when guidance is this actionable; it matches 'concrete, specific guidance covering the common cases'.

Workflow Clarity

Phases 0–4 give a clear, unambiguous sequence with explicit inputs, outputs, and file locations per phase, and the '质量检查清单' plus the '若找不到真实数据，明确标注…禁止伪造' rule act as checkpoints/feedback for the riskiest failure mode (fabricated data). It falls short of the 5 anchor because validation is post-hoc (a final checklist) rather than embedded per-phase with explicit fix-and-retry loops, and there is no instruction for what to do when a phase's output fails a checklist item. Not 3: a validation mechanism clearly exists and the sequence has no gaps.

Progressive Disclosure

The body is an orchestration-level overview; all detail is correctly pushed to one-level-deep bundle files that all exist and are not nested further (references/role-templates.md, references/report-structure.md, references/chart-guide.md — each referenced exactly where needed, e.g., '每个角色文件的标准结构，参见 `references/role-templates.md`', and indexed again in a '参考文件索引' section). The 180-line body retains only process rules (file naming, chart rules, KPA format) that Claude needs while executing, matching the clear-overview/well-signaled-references anchor.

Specificity

The description lists multiple concrete actions covering the full workflow: '自动抓取关键信息' (auto-scrape key info from docs/URLs/descriptions), role-playing 7 named roles ('用户、投资人、产品经理、市场运营、品牌运营、友商、合作伙伴'), '中间结果分角色保存' (per-role intermediate files), integrating into a report with explicit chart formats '(SVG/Mermaid/ASCII)', and appending '结论边界、前提假设及假设变动时的结论调整说明'. Coverage spans input handling through final deliverable structure, matching the comprehensive multi-action anchor; it exceeds the 'several specific actions, minor gaps' (4) anchor.

Completeness

Both 'what' and 'when' are explicitly answered. The 'what' is a detailed capability statement (scrape → 7-role analysis → per-role saved intermediates → integrated illustrated report with boundary/assumption/adjustment sections). The 'when' is an explicit '触发条件' clause with concrete trigger phrases and a mandatory-use directive ('必须使用本 skill'). This matches the 5 anchor's 'clearly and explicitly answers both what AND when with concrete trigger phrases'; not the 4 anchor where 'when could be more explicit'.

Trigger Term Quality

Extensive natural phrases users would actually say, in both Chinese and English: '产品分析', '多角色分析', '投资人视角', '用户视角', '帮我分析一下 XX 产品', '从多个角度看这个产品', 'product analysis', 'multi-role analysis', plus an explicit catch-all instruction for the vague case ('即使用户只说"帮我全面分析一下这个产品"'). This is comprehensive synonym coverage including the English equivalents, matching the 5 anchor; it clearly beats 'good coverage, a few natural terms missing' (4).

Distinctiveness Conflict Risk

The 7-role framing, per-role intermediate files, and assumption-adjustment system form a clear niche with mostly distinct triggers. However, broad trigger phrases such as '产品分析' and '帮我分析一下 XX 产品' could plausibly overlap with a generic product-analysis or competitive-research skill, so there is minor overlap risk with closely related skills (4) rather than minimal conflict risk (5).
