Conciseness

The body is dense with material Claude does not already know (sourced case facts, verified quotes, boundary tables) rather than padded explanations of known concepts, but the ~245-line body could be tightened: the 「怎么用我」 rules carry nested caveats, the 'not in this material' disclaimers are stated in multiple places, and the 局限/申报 meta-sections are lengthy. This fits 'mostly efficient but could be tightened' — not 2 (no padding of known concepts), not 4 (several sections have redundant caveat repetition).

Actionability

As an instruction-only skill the guidance is fully concrete: a 6-step review procedure with an explicit output contract (一句话判断 up front, three-column plans specified down to 「改哪一屏、哪个元素、改成什么」, top-3 actions, per-column percentage deductions), 招式 entries each with 什么时候/我会做/例子, and a 21-case index mapped to situation types. This matches 'specific examples cover the common cases'.

Workflow Clarity

Sequences are explicit and ordered (「按这个顺序走。评审时不要跳步」) with gating checkpoints (「没看到之前只问问题」, case-lookup fallback routing in rule 3, exit/recovery commands in rule 1). It falls short of 5 because there are no explicit feedback/error-recovery loops and some checkpoints (e.g., when to stop asking for materials) remain implicit.

Progressive Disclosure

Good structure: the body is an overview, a case-index table routes to the one-level-deep references/casebook.md, voice samples route to references/voice.md, and research底稿 live in references/research/ — all real files. Not 5 because the cited `FIDELITY.md` does not exist in the bundle (a dead navigation link; the validation material actually lives under references/research/validation-2026-11-09/), and references/demo-conversation-2026-04-05.md is present but never referenced.

Specificity

Names the domain (乔布斯的视角) and three concrete capability areas — 「产品判断与评审、取舍决策、对人对事的直接反馈」— which meets 'several specific actions; minor gaps'. It is not 5 because the actions are broad categories rather than a comprehensive list of concrete behaviors, and not 3 because more than two specific actions are stated.

Completeness

Explicitly answers both what (「产品判断与评审、取舍决策、对人对事的直接反馈」) and when (「说…时使用」 with four concrete trigger phrases, plus a when-not clause 「不在一般性问题上自动触发」), matching the top anchor of concrete trigger phrases for both.

Trigger Term Quality

Four natural quoted trigger phrases (「用乔布斯的视角」「乔布斯会怎么看」「切换到乔布斯」「让乔布斯评一下」) plus an explicit non-trigger clause give good coverage a user would actually say. It falls short of 5 because common variations such as 「扮演乔布斯」 and English-language triggers (e.g. 'as Steve Jobs') are missing.

Distinctiveness Conflict Risk

A clear niche (Jobs-perspective persona) with distinct, quoted triggers and an explicit anti-misfire clause (「不在一般性问题上自动触发」), so overlap with other skills is minimal.
