Conciseness

The body is dense and mostly assumes competence, but a few vivid passages (e.g. '记忆层级不是分类抽屉，而是多层防爆盾') are rhetorical rather than strictly necessary and could be trimmed.

Actionability

Provides a quantitative threshold (>800 Tokens), concrete decision rules ('disclosure 会完全不同吗？'), a hard blacklist of forbidden phrases, and explicit quality tests — fully actionable for an instruction-only skill.

Workflow Clarity

A clear 5-step sequence with explicit validation checkpoints (cold-start test, parent-node stress test) and feedback loops ('必须回到步骤 4 重写') for the destructive/batch operations involved.

Progressive Disclosure

Under 50 lines, single-purpose, with no bundle files needed and well-organized sections (诊断信号, 拆分流程); cross-references to sibling skills are one-level and clearly signaled.

Specificity

Names the domain ('节点分解') and one concrete action (decomposing nodes) with specific trigger conditions, but does not enumerate multiple distinct actions, so coverage is not comprehensive.

Completeness

Explicitly states the 'what' ('节点分解') and an explicit '当…时使用' trigger with concrete conditions, satisfying both halves with concrete trigger phrases.

Trigger Term Quality

Contains relevant trigger phrases ('节点体积过大', '多个不相关概念', 'disclosure无法覆盖') but lacks common synonyms or variations a user might naturally say.

Distinctiveness Conflict Risk

Positioned as the explicit inverse of the merge-up skill with a distinct trigger (oversized/multi-concept nodes), leaving only minor overlap risk with closely related audit skills.
