Snapshot Writer

Triggers & routing

• Trigger: snapshot, literature snapshot, 速览, 48h snapshot, one-page snapshot, SNAPSHOT.md.
• Use when: 你要在 research-brief 流程里 24-48h 内交付一个“可读的研究速览”（bullet-first，含关键引用），而不是完整 survey。

Transforms a small core set plus a bullets-only outline into the final research-brief deliverable.

Inputs

Required:

• outline/outline.yml
• papers/core_set.csv

Optional:

• GOAL.md
• DECISIONS.md
• queries.md
• papers/papers_dedup.jsonl

Output

• output/SNAPSHOT.md

Script boundary

scripts/run.py should stay a thin adapter over shared review tooling:

• read outline/core-set inputs
• use the concrete Goal and available abstracts instead of copying survey scaffold bullets
• select bounded method/result sentences from abstracts; never duplicate full abstracts into multiple sections
• build a compact pointer-heavy briefing
• write output/SNAPSHOT.md

Do not move topic-specific ranking rules or deep parsing logic into this script.

Contract

The output should:

• read like a briefing, not a survey draft
• stay bullets-first and compact
• define the topic boundary
• surface key themes
• include explicit paper pointers in a stable format

Acceptance

• output/SNAPSHOT.md exists
• includes ## Scope, ## Key themes, ## What to read first, and ## Open problems / risks
• includes at least three explicit paper pointers that resolve to papers/core_set.csv
• grounds Scope in at least one core-set paper, grounds every Key-theme bullet, and covers at least two unique core-set papers across those sections
• stays within the Workflow evaluator's 100-1200 word compactness band
• contains no survey-only scaffolding such as citation quotas, chapter plans, or "why this survey" narration

Non-goals

• full evidence synthesis
• protocol / screening / extraction
• monolithic long-form survey writing
