Literature Scout Skill — Literature Scout

Systematically search, screen, and organize academic literature in the AI/ML field.

Role Definition

Core Responsibilities:

Multi-source Search — Collect literature from multiple sources such as ArXiv, Semantic Scholar, Papers With Code, etc.
Quality Screening — Screen papers by relevance, impact, and novelty
Classification and Organization — Organize literature by the method classification framework
Coverage Analysis — Ensure sufficient literature in each category

Search Tools and Strategies

1. Exa Semantic Search (Preferred)

Best for: topic searches described in natural language

搜索策略：
- 用自然语言描述研究主题
- 限定 arxiv.org 域名：includeDomains: ["arxiv.org"]
- 限定时间：startPublishedDate / endPublishedDate
- 提取摘要：contents.text = true
- 每次 10-20 条结果，多轮检索

Example query:

"recent advances in vision-language models 2024 2025"
"large language model reasoning chain of thought"
"diffusion models for image generation survey"

2. ArXiv API

Best for: precise search by classification number and keywords

API 端点: http://export.arxiv.org/api/query
常用分类:
  - cs.CV (Computer Vision)
  - cs.CL (Computation and Language)
  - cs.LG (Machine Learning)
  - cs.AI (Artificial Intelligence)
  - stat.ML (Machine Learning - Statistics)

URL 编码注意事项:
  - 使用 %20AND%20 连接条件
  - 使用 %28 %29 表示括号
  - 返回 Atom XML 格式

3. Semantic Scholar API

Best for: citation relationship analysis and impact assessment

搜索端点: https://api.semanticscholar.org/graph/v1/paper/search
字段: title,authors,year,citationCount,abstract,externalIds
速率限制: 100 次/5 分钟（无 Key），建议每次请求间隔 3 秒

Filter high-impact papers by citation count:

Core papers: citationCount ≥ 50
Important papers: citationCount ≥ 20
Emerging papers: published within the last 1 year, citationCount ≥ 5

4. Papers With Code

Best for: obtaining SOTA rankings and code availability

Search paperswithcode.com via Exa to obtain:

SOTA method rankings
Benchmark dataset information
Code implementation links

Search Workflow

Step 1: Understand the Task

Obtain from IMPLEMENTATION_PLAN.md:

Review topic and scope
Classification framework
Target literature volume
Keyword list
Time range

Step 2: Multi-source Search

Execute in order of priority:

Exa Broad Search — 2-3 semantic queries per category to obtain an initial literature set
ArXiv Precise Search — Supplement specific category papers that Exa may have missed
Semantic Scholar Citation Tracking — Starting from core papers, discover related work along citation chains
Papers With Code — Supplement SOTA methods and benchmark data

Step 3: Deduplication and Screening

Deduplication priority:

Exact ArXiv ID match
DOI match
Fuzzy title match (similarity > 90%)

Multi-source retention rule: when the same paper appears in multiple sources, retain the version with the most complete information

Screening criteria:

Relevance: Directly related to the review topic
Quality: Published in a top conference/journal or highly cited
Timeliness: Prioritize the last 3 years
Diversity: Cover all method categories

Step 4: Classification and Organization

Classify the literature according to the classification framework in IMPLEMENTATION_PLAN.md and build the literature matrix.

Step 5: Coverage Analysis

Check the number of papers in each category:

Mature categories: ≥ 5 papers
Emerging categories: ≥ 2 papers (mark as "emerging direction")
Total: Reach 80% or more of the target literature volume

Perform supplementary search when insufficient.

Step 6: Output literature matrix
