Conciseness

The body is mostly tight — tables, short rule statements, good/bad example pairs — but it is ~300 lines that essentially restate, in condensed form, the entire 170-line reference file (Winston's formula, the four heuristics, slide sins, the star, meta-techniques), and the 速查清单 section then repeats those rules a third time. This fits 'mostly efficient but includes some unnecessary explanation or could be tightened'; it is not a 2 because there is little conceptual padding of things Claude already knows, and not a 4 because the body/reference duplication and the promotional footer are clear trim candidates.

Actionability

The four usage scenarios give concrete, executable guidance: a 7-item review checklist ("有没有赋能承诺？"...), specific script checks ("前10秒的钩子"、"每3-5分钟...循环点"), a per-slide audit against the 七宗罪 table, and a 5-dimension 10-point scoring rubric with a defined output ("综合评分 + 逐项建议 + 优先修改项（改动最小、收益最大的3件事）"). This is 'mostly executable guidance with minor gaps' — for an instruction-only skill the guidance is concrete — falling short of 5 only because the review scenarios lack an explicit interaction template (e.g., how to ask for the outline or deliver the score).

Workflow Clarity

Each scenario has a clear sequence: input type (大纲/脚本/幻灯片) → checklist evaluation → 5-dimension score → prioritized top-3 fixes, and the 速查清单 provides explicit pre/during/post checkpoints. This matches 'clear sequence with most checkpoints present'; it is below 5 because the scenarios are presented as parallel options with no guidance on choosing between them or combining them when a request is ambiguous, and there is no error-recovery loop for, e.g., a user submitting only partial material.

Progressive Disclosure

Structure and headers are good and the reference is real and clearly signaled once at the top ("参考材料：`references/patrick-winston-how-to-speak.md`"), but the body inlines ~200 lines of the very methodology that the reference file already contains in more detail (with timestamps) — content that clearly belongs in the separate file is duplicated inline. This fits 'some structure but could be better organized; content that should be separate is inline'; not a 2 because sections, tables, and the single one-level-deep reference are well organized, and not a 4 because the body/reference split is not an actual division of labor.

Specificity

The description names the domain clearly ("演讲与分享教练", "基于Patrick Winston（MIT AI教授）的How to Speak方法论") and lists scenarios ("线下培训、技术分享、B站教程视频"), but the only action verb is the generic "帮助准备" — no concrete capabilities (e.g., reviewing outlines, scoring scripts, checking slides) are stated. This matches the anchor 'Names the domain but actions are minimal or generic'; it is not a 3 because no 1-2 concrete actions are listed, and not a 1 because the domain and methodology source are specific.

Completeness

Both parts are present: a 'what' ("演讲与分享教练...帮助准备...演讲场景") and an explicit 'when' with concrete trigger phrases ("当用户提到...时使用此技能"). It is not a 5 because the 'what' is vague about what the skill actually does (review, scoring, optimization are only in the body), and clearly above 3 since the 'when' clause is explicit with enumerated triggers.

Trigger Term Quality

Provides good natural keyword coverage: "演讲"、"分享"、"培训"、"讲课"、"PPT演讲"、"开场"、"结尾"、"如何讲"、"演讲结构" — phrases a Chinese-speaking user would naturally say. It falls short of the 5 anchor because common variations like "汇报"、"演讲稿"、"路演"、"做PPT" are missing; it is above 3 because both root terms and multiple natural variations are present.

Distinctiveness Conflict Risk

The Winston-methodology coaching niche is distinct, and specific triggers like "讲课"、"开场"、"演讲结构" are unlikely to fire the wrong skill. Minor overlap risk remains: broad triggers like "分享"、"培训"、"PPT演讲" could collide with general training or presentation-creation skills, keeping it below the 'clear niche with minimal conflict risk' anchor.
