# Analyzing Research Papers

This skill provides expertise in systematically analyzing research papers to extract key insights, evaluate methodological rigour, and contextualize findings for researchers.

## Paper Access Methods

### Input Formats Accepted

**Local files:**
- Absolute paths: `/path/to/paper.pdf`
- Relative paths: `./papers/smith2024.pdf`
- Markdown files: `paper.md`

**DOIs:**
- Standard format: `10.1234/journal.2024.12345`
- With prefix: `doi:10.1234/journal.2024.12345`
- Resolve using: `https://doi.org/{doi}`

**URLs:**
- ArXiv: `https://arxiv.org/pdf/2301.12345.pdf`
- Journal websites: Direct PDF or HTML links
- Preprint servers: bioRxiv, medRxiv, etc.

### Handling Access Issues

**Paywalled content:**
- Work with available abstract and metadata
- Extract what's publicly accessible
- Note limitations in summary
- Suggest open access alternatives

**PDF reading failures:**
- Request text version if available
- Try alternative formats (HTML, arXiv)
- Extract from DOI metadata

## Analysis Framework

### Initial Scan

**Identify paper structure:**
- Abstract and key claims
- Section organization (IMRaD vs custom)
- Figures and tables overview
- Reference density and key citations

**Classify paper type:**
- Theory: Proofs, mathematical foundations, formal results
- Methods: New algorithms, techniques, computational approaches
- Application: Domain-specific use cases, case studies
- Review: Surveys, systematic reviews, meta-analyses
- Empirical: Experimental results, observations, measurements

### Content Extraction Priorities

**Must extract:**
1. Main contribution(s) and claims
2. Methodological approach and assumptions
3. Key results with statistical evidence
4. Limitations acknowledged
5. Related work positioning

**Important to capture:**
- Experimental setup and validation
- Implementation details
- Performance metrics and comparisons
- Dataset characteristics
- Reproducibility information

**Nice to have:**
- Future work suggestions
- Broader implications
- Alternative approaches considered
- Failure modes discussed

## Quality Assessment Criteria

### Methodological Rigour

**Strong indicators:**
- Clear research questions
- Appropriate methodology for questions
- Controlled comparisons
- Statistical significance properly assessed
- Limitations openly discussed
- Assumptions explicitly stated

**Weak indicators:**
- Vague objectives
- Methodology not justified
- Cherry-picked results
- Over-claiming based on limited evidence
- Ignoring contrary evidence
- Unacknowledged assumptions

### Reproducibility Assessment

**High reproducibility:**
- Code publicly available
- Data accessible or well-described
- Implementation details complete
- Hyperparameters specified
- Random seeds provided
- Environment documented

**Low reproducibility:**
- "Implementation details omitted for brevity"
- No code or data shared
- Vague parameter descriptions
- Critical details missing
- Non-standard methods without explanation

### Impact Potential

**High impact indicators:**
- Addresses important problem
- Novel approach or insight
- Strong empirical results
- Generalizable beyond specific case
- Clear practical applications
- Challenges existing assumptions

**Limited impact indicators:**
- Incremental improvement
- Narrow applicability
- Limited novelty
- Weak empirical support
- Unclear practical value

## Analysis Structure

### Overview Section

**Synthesize (2-3 paragraphs):**
- What problem does this address?
- What's the main contribution?
- What's the key finding or result?
- Why does this matter?

### Highlights (Bullet Points)

**Extract:**
- Most important findings
- Key methodological innovations
- Surprising or counter-intuitive results
- Practical implications
- Limitations to be aware of

### Strengths Assessment

**Methodological strengths:**
- Rigorous experimental design
- Appropriate statistical analysis
- Comprehensive evaluation
- Clear presentation

**Impact strengths:**
- Novel contributions
- Practical applicability
- Theoretical insights
- Reproducibility support

### Weaknesses Assessment

**Be specific and fair:**
- Methodological limitations
- Scope constraints
- Unclear explanations
- Missing comparisons
- Reproducibility concerns
- Over-claims not supported by evidence

**Distinguish:**
- Fundamental flaws (invalidate conclusions)
- Important limitations (affect interpretation)
- Minor issues (don't affect main findings)

## Section-by-Section Analysis
