Conciseness

The ~55-line body is lean and assumes domain competence — no generic concept explanations — with useful sections (适用/不适用场景, 高信号规则, 关键陷阱). It loses a point for redundancy: the identical five-file reference list appears twice (快速指导 item 3 and 延伸阅读), which could be collapsed. It is efficient with minor trimmable material (anchor 4), not the every-token-earns-its-place case of anchor 5.

Actionability

Guidance is partially concrete — a four-layer decomposition (入口层/服务层/引擎层/数据层) and named per-layer documents — but the referenced files (reference/1-api-layer.md … reference/5-event-driven.md) do not exist in the bundle, and the body gives no concrete source anchors (packages, classes, or file paths in the Process module) to act on without them. This matches anchor 3 ('some concrete guidance but incomplete; missing key details') rather than anchor 4's mostly-executable guidance.

Workflow Clarity

There is a coherent decision procedure: scope check via 适用/不适用场景, layer decomposition, per-topic reference routing, and cross-skill routing rules (items 4–6). This is an understanding/orientation skill with no destructive or batch operations, so validation checkpoints are not required; sequence is clear with only minor gaps (e.g., no guidance on what to do if a referenced doc is missing), matching anchor 4.

Progressive Disclosure

The in-body structure is well signaled and one level deep, but every referenced path — "reference/1-api-layer.md" through "reference/5-event-driven.md" — is absent: the bundle contains no reference/, references/, scripts/, or assets/ directories at all, and the paths use a 'reference/' spelling that does not match the conventional 'references/' layout. The navigation the entire skill depends on does not resolve, which is a broken-disclosure defect below the midpoint (anchor 3's 'references present but not clearly signaled' understates it; anchor 2's structurally broken organization is the closer fit).

Specificity

The description enumerates several concrete capability areas — "流水线 CRUD、构建启动、运行时状态、引擎控制、事件驱动和数据库持久化" — giving specific coverage of the module's scope, though the only verb is the generic "处理", so the actions read as noun-phrase capability areas rather than full verb-led actions. This sits above anchor 3 (only 1–2 concrete actions) but the generic verb keeps it below anchor 5's fully action-verb comprehensive list.

Completeness

Both parts are explicit: the 'what' is "处理 BK-CI Process 流水线核心模块…例如流水线 CRUD、构建启动…" and the 'when' is the concrete trigger clause "当用户要改流水线主链路而不是外围支撑模块时优先使用", which even includes a negative boundary. It clearly matches anchor 5 and is not merely the weaker 'when could be more explicit' case of anchor 4.

Trigger Term Quality

Natural terms a BK-CI user would say are present: "流水线", "构建", "Process", "流水线主链路". Coverage is good but misses common variations such as the English word "pipeline", "编排", or file/module-name triggers, so it falls between anchor 4 (good coverage, a few natural terms missing) and anchor 5, closer to 4.

Distinctiveness Conflict Risk

The niche is well carved out — BK-CI's Process main chain, explicitly contrasted against "外围支撑模块" — and it names sibling-module territory to avoid. Minor overlap remains with closely related dispatch/agent/worker skills around build execution, so it is 'mostly distinct with minor overlap risk' (anchor 4) rather than fully minimal-conflict (anchor 5).
