Conciseness

The body is lean and assumes competence — no padding explaining what a BP or flywheel is, and the framework sections (「地基」「创生公式」) convey author-specific philosophy Claude cannot infer, so they earn their tokens. Minor trimming is possible (e.g., the three-line 亚马逊/特斯拉/Google formula examples and the 「惯常问法」 comparison table could be tightened), which keeps it at anchor 4 rather than 5; not a 3 because there is no explanation of concepts Claude already knows.

Actionability

Guidance is fully concrete for an instruction-only skill: a fixed five-section report skeleton with an explicit table schema, a three-tier forced verdict (「秩序创造机器 / 有潜力 / 秩序搬运」), concrete worked examples (「叫它『搜索引擎公司』等于什么都没说；说它是『人类认知基础设施的垄断运营商』」), a banned-words list, and exact output mechanics (「`20260326153000==z--投资分析-example-ai.org`」, 「用 Write 工具写入」). Per the scoring notes, absence of code is not penalized when guidance is this actionable; not a 4 because the common cases are covered end-to-end with copy-paste-ready specifics (naming pattern, directory, tool).

Workflow Clarity

The sequence is clear: inputs → data gathering for known companies (「用 Research skill 或 subagent 抓最新财报」) → five ordered report sections → output write with naming convention → 「写完把完整路径报给用户」 as a completion step. It stays at anchor 4 because validation checkpoints are only implicit (rule 1 「查不到的直接标注」 is a data-integrity rule, not a verify step; there is no check that the file was written correctly); not a 3 because the sequence itself is coherent, well-ordered, and unambiguous. No destructive/batch operations, so the workflow-clarity cap does not apply.

Progressive Disclosure

A single-file skill with no bundle directories (references/, scripts/, assets/ absent) and no external references to verify; all cross-referenced tooling (Research skill, subagent, denote naming, Write tool) exists outside the bundle by design. Sections are well-organized with a clear progression (地基 → 输入 → 报告结构 → 输出 → 生成规则). Anchor 4 rather than 5 because at ~110 lines the worked examples (创生公式 examples, banned phrases) are borderline candidates for a reference file; not a 3 because nothing is misplaced or buried — the structure is clean and navigable.

Specificity

The description states concrete inputs (「公司名、BP、创始人对话记录」), a concrete deliverable (「写一份深度投资分析报告」), and the distinctive analytical frame (「这个项目是不是一台『秩序创造机器』」) — several specific elements with only minor coverage gaps (it never mentions the output file format or the research/data-gathering step). Not a 5 because it centers on a single deliverable action rather than a comprehensive list of multiple concrete actions; not a 3 because inputs, output, and approach are all explicitly stated beyond a bare domain-plus-action.

Completeness

Both questions are answered explicitly: what — 「给一个项目（公司名、BP、创始人对话记录），写一份深度投资分析报告」— and when — 「Use when user says '投资报告', '投资分析', ... or provides entrepreneur conversation records wanting investment evaluation」. This mirrors the anchor-5 example structure exactly; not a 4 because the 'when' clause is already fully explicit with concrete trigger phrases.

Trigger Term Quality

Trigger coverage is comprehensive and bilingual: 「投资报告」「投资分析」「分析这个项目」「写投资报告」, 'investment report', 'invest analysis', plus material-type triggers (meeting notes, pitch decks, founder interviews) — matching the anchor's standard of natural terms including synonyms. Not a 4 because no commonly used variation is obviously missing.

Distinctiveness Conflict Risk

The niche (investment evaluation reports with a specific framework) is distinct and most triggers are domain-specific, but 「分析这个项目」 and 「asks for analysis」 are broad enough that a user wanting a general project/product analysis could trigger this skill incorrectly. Mostly distinct with minor overlap risk against general analysis skills — anchor 4, not 5; not 3 because the core triggers clearly point at investment evaluation.
