Synthesis Writer

Triggers & routing

• Trigger: synthesis, evidence synthesis, systematic review writing, 综合写作, SYNTHESIS.md.
• Use when: evidence-review 完成 screening+extraction（含 bias 评估）后进入写作阶段（C5）。
• Skip if: 还没有 papers/extraction_table.csv（或 protocol/screening 尚未完成）。
• Network: none.
• Guardrail: 以 extraction table 为证据底座；明确局限性与偏倚；不要在无数据支撑时扩写结论。

Transforms the extraction table into the final evidence-review narrative.

Input

• papers/extraction_table.csv

Optional:

• output/PROTOCOL.md
• DECISIONS.md

Output

• output/SYNTHESIS.md

Contract

The synthesis must include stable sections:

• ## Included studies summary
• ## Findings by theme
• ## Risk of bias
• ## Supported conclusions
• ## Needs more evidence

Script boundary

scripts/run.py should:

• summarize extracted evidence conservatively
• keep conclusions bounded by table contents
• render the stable section structure

It should not invent findings not grounded in the extraction table.

Acceptance

• output exists
• includes all stable sections
• stays table-grounded and bounded

Non-goals

• upstream extraction repair
• free-form speculative discussion
