Chapter Skeleton

---
name: chapter-skeleton
description: |
  Build a retrieval-informed chapter skeleton (`outline/chapter_skeleton.yml`) from taxonomy/core scope before stable H3 decomposition.
  **Trigger**: chapter skeleton, chapter-level outline, H2 skeleton, section-first survey, 章节骨架, 章级骨架.
  **Use when**: survey structure should stabilize chapter-level intent before subsection mapping and writing cards.
  **Skip if**: `outline/chapter_skeleton.yml` already exists and is refined.
  **Network**: none.
  **Guardrail**: NO PROSE; do not invent papers; keep output chapter-level only.
