Conciseness

Lean ~60-line body with terse bulleted navigation and no padding or re-explanation of concepts Claude already knows; every line earns its place and assumes Claude's competence.

Actionability

Provides concrete, decision-ready guidance — a named 5-layer model, an ordered main pipeline link, a module→skill mapping table, and question→module attribution rules — with only minor gaps (some mappings name a skill without the trigger that selects it).

Workflow Clarity

Clear 4-step sequenced navigation workflow (build layer view → trace main link → pick skill by module boundary → judge problem attribution); no validation checkpoints, but none are warranted for non-destructive navigation, so it sits just below 5.

Progressive Disclosure

Well-organized into focused sections and explicitly acts as an overview that defers detail to per-module skills and reference/, keeping the file one level deep; no bundle files exist, and the section structure alone earns the top score for a navigation skill.

Specificity

Names the BK-CI domain and 1–2 concrete actions ('判断某个需求应该落在哪个 BK-CI 模块', '理解流水线全链路协作'), but coverage is not comprehensive; it is a navigation skill, so the action list is inherently narrow.

Completeness

Explicitly answers 'when' ('用于…时使用') with concrete trigger phrases, and the 'what' (navigation + module attribution) is present but implied through the use-cases rather than stated as a crisp standalone capability, so it is not a clean 5.

Trigger Term Quality

Good coverage of natural trigger phrases a user would say ('跨模块开发', '排查链路归属', '判断某个需求应该落在哪个模块', '快速理解流水线全链路协作'), with a few common variations/synonyms missing.

Distinctiveness Conflict Risk

Clear niche (BK-CI global/cross-module navigation) with distinct triggers, and it explicitly differentiates from single-module skills ('单模块修改时优先读取对应模块 skill'), minimizing wrong-skill activation.
