Conciseness

The body is lean: the seven criteria, five-step workflow, output template, negative list, and one worked example all carry weight, and none of it explains concepts Claude already knows. Minor trims are possible — the "核心张力" blockquote is partly a restatement of criteria 4/5/6, and the worked example slightly exceeds what the format template already conveys — matching anchor 4 rather than the perfectly lean anchor 5.

Actionability

Guidance is concrete throughout: concrete search query patterns ("<行业> 2026 热点 争议", "<行业> 痛点 为什么难"), five named generation lenses each with a driving question, explicit rejection rules per criterion in Step 4, a copy-ready output template, and a fully worked example for 预制菜. For an instruction-only skill this is as actionable as copy-paste code, matching anchor 5.

Workflow Clarity

The five steps are clearly sequenced (understand industry → verify online → generate via lenses → score and eliminate → format output), with an explicit validation gate in Step 4 (逐条打分筛选, 淘汰不合格) and a complete fallback path in Step 2 for when the required search tool is unavailable, including a required output disclaimer. No destructive or batch operations are involved, so no feedback-loop cap applies; this matches anchor 5.

Progressive Disclosure

No bundle files exist (references/, scripts/, assets/ are absent) and none are referenced in the body, so there are no broken or nested-reference risks. The ~90-line body is entirely self-contained, appropriately so — the criteria, workflow, format, and calibration example all belong together — and section headers make navigation trivial, matching the well-organized-structure standard for self-contained skills.

Specificity

The description names the domain and a concrete action pair — "提出若干个'好问题'——不作解答，但给出扎实理由" — and enumerates six concrete qualifying criteria (老大难或近期热点、真实不虚构、牵连广泛、深刻难解、够得着、有讨论张力). It lists several specific behaviors with only a minor gap (no mention of the default output count of 5-7), matching anchor 4 rather than 5, which requires multiple distinct concrete actions comprehensively covered.

Completeness

Both 'what' (提出好问题并给理由，不作解答) and 'when' ("当用户说……时使用本技能" with four concrete trigger phrases) are explicitly and clearly stated, exactly matching the anchor-5 example pattern of capability statement followed by explicit 'Use when...' triggers.

Trigger Term Quality

It quotes four natural user phrasings verbatim: "针对X行业提几个好问题", "这个行业有哪些值得深挖的真问题", "帮我找选题/议题/讨论话题", "这行的痛点/争议是什么", plus example industries (新能源汽车、预制菜、少儿编程、殡葬、货运物流). This is comprehensive natural-language trigger coverage including synonyms (选题/议题/讨论话题/痛点/争议), matching anchor 5.

Distinctiveness Conflict Risk

The skill occupies a clear niche — generating open industry questions without answering them — and its trigger phrases (提几个好问题、找选题、这行的痛点/争议是什么) are specific to that intent. Even the broadest trigger (帮我找选题/讨论话题) is anchored to industry analysis, keeping conflict risk with research or Q&A skills minimal, matching anchor 5.
