Conciseness

The body is dense and almost entirely operational — search query templates, a Mermaid skeleton, per-company analysis templates, ASCII comparison tables — with little explanation of concepts Claude already knows. Minor trimmable padding exists: the persona section (“在顶级投行工作超过15年的资深分析师”) and the checklist partially restating earlier requirements keep it at 4 rather than the lean anchor 5.

Actionability

Guidance is copy-paste ready: seven exact web_search query templates (“{行业} 产业链 上市公司 龙头 {当前年份}”), a complete Mermaid flowchart with classDefs and node placeholders, a full per-company markdown template, ASCII table/bar formats, and a concrete save step with naming convention (“lithium-battery-chain-202506.md”) and `mkdir -p markdown`. Quantitative constraints (5–7 searches, 4–6 nodes, 2–4 companies per node) leave nothing ambiguous.

Workflow Clarity

The 9-step sequence is clearly ordered with quantitative bounds and ends with a quality self-check checklist (结构完整性/内容质量), which is an explicit checkpoint — stronger than anchor 3. It stops short of anchor 5 because there is no feedback loop: the checklist tells the model what to verify but never says what to do when a check fails (revise and re-verify), leaving a minor validation gap.

Progressive Disclosure

The skill is a single ~340-line monolith with no references/, scripts/, or assets/ files. Internal structure is good (clearly headed steps), but large self-contained blocks — the 70-line 企业分析模板, the good/bad writing examples, the Mermaid skeleton — are inlined when they clearly belong in one-level-deep reference files that the model loads only when writing that section. This matches the anchor where content that should be separate is inline; it is above 2 only because sectioning and navigation within the file are well done.

Specificity

The description lists many concrete actions — “系统梳理该行业产业链各节点，列出各节点代表性上市公司，深度分析商业模式、上下游关系、核心竞争力、护城河、风险揭露、竞争格局” plus a concrete output contract (“图文并茂的Markdown报告，保存到当前项目 markdown/ 目录”) — matching the comprehensive anchor. It falls short of 5 only because the tail sentence (“输出为Markdown文件，保存到markdown/目录，图文并茂…”) restates the output format already given, padding the description rather than adding new capability; per the verbosity guideline this repetition keeps it at 4 rather than 5.

Completeness

Both questions are explicitly answered: the “what” is the full analysis-and-report pipeline in the opening clause, and the “when” is an explicit “触发条件：…” clause with concrete trigger phrases plus an explicit instruction to fire on indirect phrasings. This mirrors the anchor-5 example structure; a 4 would require the when-clause to be less explicit, which it is not.

Trigger Term Quality

Trigger coverage is exhaustive and natural, including colloquial variants users would actually say: “帮我分析XX行业”, “XX行业怎么投”, “梳理XX产业链”, “XX上下游企业”, and even “即使用户只说‘帮我看看XX行业’或‘XX行业值得投吗’，也应使用本skill”. This matches the anchor of comprehensive natural-term coverage including synonyms; no common phrasing is missing.

Distinctiveness Conflict Risk

The niche (产业链投行研究报告 for ordinary investors) is distinct with dedicated triggers like “XX行业护城河” and “XX行业竞争格局” that no generic document- or code-analysis skill would claim. Conflict risk with adjacent skills (e.g., generic stock screens) is minimal because the trigger phrases are chain- and moat-specific.
