Mostly efficient with concrete commands and structured lists, but the 'Step 0: 读取共享配置' and '配置来源' sections duplicate the same config-source explanation, and '注意事项' partly restates earlier points. Not a 3 because it could be tightened by merging the redundant config sections.

Provides fully executable commands with concrete paths — 'python3 ../daily-papers/fetch_and_score.py > /tmp/daily_papers_top30.json' and 'python3 ../daily-papers/enrich_papers.py /tmp/...top30.json /tmp/...enriched.json' — copy-paste ready with the --days N substitution clearly explained. Not a 2 because the guidance is concrete and complete rather than pseudocode.

Clear phased sequence (Step 0 → 解析天数 → Phase 1+2 → Phase 3 → 输出) with explicit validation checkpoints ('**检查输出**：确认 /tmp/daily_papers_top30.json 存在且包含有效 JSON 数组') and error-recovery guidance (stderr diagnosis, arXiv fallback, <20 papers, weekend strategy). Not capped at 2 because validation is present rather than missing for this batch operation.

Well-organized into clear sections with one-level-deep references to the implementation scripts (fetch_and_score.py, enrich_papers.py) and shared config; no nested document chains. Not a 2 because content is appropriately split and references are clearly signaled.

Lists multiple concrete actions — '抓取 arXiv + HuggingFace 最新论文，打分筛选，富化信息，输出到 /tmp/daily_papers_enriched.json' — naming the domain and specific pipeline steps. It is not the level below (2), which only names a domain and some actions without being comprehensive.

Answers both 'what' (fetch + score + enrich + output to file) and 'when' via explicit trigger guidance ('触发词' and multi-day examples), the equivalent of a 'Use when…' clause. Not capped at 2 because the when-clause is explicit rather than implied.

Explicit trigger words '论文抓取'、'跑一下论文抓取' plus multi-day variations ('过去3天论文推荐'、'最近5天'、'抓 3 天的论文') give good coverage of phrases a user would naturally say. Not a 2 because common variations are present rather than missing.

Clear niche (arXiv + HuggingFace paper fetching, '3 步流水线的第 1 步') with distinct triggers, unlikely to overlap with unrelated skills. Not a 2 because the niche and triggers are specific enough to avoid overlap.
