Conciseness

The body is dense and functional — 6 compact core principles and a routing table that carries real load — with almost no concept-explanation padding. Minor trimmable redundancy keeps it at anchor 4 rather than 5: the no-match rule appears twice ("路由表与能力索引均无法命中…" in both 加载规则 and 边界与判停), and the 触发与不触发 exclusions largely restate the frontmatter description's 不适用于 clause.

Actionability

As an instruction-only routing skill, the guidance is fully executable: every intent row maps to an exact file path ("references/capabilities/wealth-structure.md" — all 19 verified to exist), loading rules are quantified ("再按路由表加载 1 张能力卡；任务明确跨域时最多加载 2 张"), and fallback behavior for unmatched intents is explicit. This covers the common cases with copy-paste-ready specificity, matching anchor 5 under the instruction-skill scoring note.

Workflow Clarity

The workflow is clearly sequenced (read this file → route by intent → load one capability card → answer, with non-capability queries routed to overview/glossary/cheatsheet) and includes an explicit error-recovery loop: routing misses fall back to capability-index.md ("本表未覆盖的意图先查这里") and only then declare out of scope ("明确告知超出本书范围，不硬套书中框架"). Explicit stop conditions ("涉及医疗/法律/人身安全 → 停止套用方法论，建议专业求助") function as validation checkpoints; no destructive or batch operations exist to require a cap.

Progressive Disclosure

The body is a true overview: 6 core principles inline for quick answers, with everything else routed to one-level-deep references — 19 capability cards plus overview/glossary/cheatsheet/capability-index, all verified to exist, and the capability cards themselves contain no further nested references. Navigation by user intent ("怎么才能更幸福… → references/capabilities/happiness-skill.md") is unambiguous, matching anchor 5's clear overview with well-signaled references.

Specificity

The description enumerates concrete, well-scoped domains with parenthetical specifics ("财富构建(怎么赚钱/股权期权/杠杆/副业与职业定位/时薪与外包决策)、判断与决策(重大选择纠结/心智模型/打工vs创业)"), matching the 'several specific items, minor gaps' anchor. It falls short of 5 because the skill's own action is never explicitly stated — '当用户…寻求建议时调用' specifies when to invoke, but what the skill does with the query (provide the book's principles/frameworks as guidance) is only implied.

Completeness

The 'when' is explicit, concrete, and even exclusion-scoped ("当用户询问《纳瓦尔宝典》…相关内容，或在以下领域寻求建议时调用" plus "不适用于: 具体投资标的与选股、临床心理治疗、急性危机"), while the 'what' — advising within these domains using the book's methodology — is present but derived from the domain list rather than stated outright. This matches anchor 4 (both present, one could be more explicit); it exceeds anchor 3 because the trigger clause is explicit, not weakly implied.

Trigger Term Quality

The Triggers line ("纳瓦尔/Naval/纳瓦尔宝典/致富/财富/幸福/判断力/冥想/读书/人生意义") plus natural user phrasing in the domain list ("怎么赚钱", "刷手机上瘾", "攀比妒忌", "该不该信玄学") gives good natural-term coverage. A few common variants users would say (焦虑, 换工作, 副业, 跳槽) appear only indirectly or not at all in the trigger set, keeping it at anchor 4 rather than 5.

Distinctiveness Conflict Risk

Anchoring to a named book ("《纳瓦尔宝典》(The Almanack of Naval Ravikant)") with explicit exclusions makes the niche clear and mostly distinct from other skills. Broad trigger words like "致富/财富/幸福/冥想/读书" still overlap generic finance-, happiness-, meditation-, and reading-advice skills, which is exactly anchor 4's 'minor overlap risk with closely related skills' rather than 5's minimal conflict risk.
