Transition Weaver (LLM-first; NO NEW FACTS)

Triggers & routing

• Trigger: transition weaver, weave transitions, coherence, 过渡句, 承接句, 章节连贯性.
• Use when: outline/subsection_briefs.jsonl exists and you want coherent flow before/after drafting (typically Stage C5).

Purpose: produce a small, low-risk “transition map” so adjacent subsections do not read like islands.

This skill is intentionally low-risk and deterministic:

• the script writes outline/transitions.md from adjacent subsection titles + brief bridge handles
• the generated transitions stay paper-safe and avoid adding new facts or citations

Transitions should answer:

• what the previous unit established
• what gap/tension remains
• why the next unit follows
