## Information to Extract

For each repository or project, gather:

- Key features and capabilities
- Installation and usage instructions
- Common issues and their solutions
- Alternative implementations
- Dependencies and requirements
- License and usage restrictions
- Breaking changes across versions

## CLI Tools for Research

Leverage these tools for efficient research:

**GitHub CLI (`gh`):**
```bash
# Repository information
gh repo view owner/repo

# Get repository stats
gh api repos/owner/repo | jq '.stargazers_count, .forks_count, .open_issues_count'

# Recent releases
gh release list --repo owner/repo

# View issues
gh issue list --repo owner/repo --state all --limit 20

# Check PR activity
gh pr list --repo owner/repo --state all --limit 20

# Search repositories
gh search repos --language javascript --sort stars --limit 10 "query"
```

**Package Registry Tools:**
```bash
# npm package info
npm view package-name
npm view package-name versions

# View package downloads
npm info package-name

# Python packages
pip show package-name
```

**Web Research:**
```bash
# Use WebSearch for current information
# Use WebFetch for specific documentation pages
```

**Node.js Analysis Scripts:**

Create scripts to analyze repository data:

```javascript
#!/usr/bin/env node
import { exec } from 'child_process';
import { promisify } from 'util';

const execAsync = promisify(exec);

// Analyze repository activity
const repoStats = async (owner, repo) => {
  const { stdout } = await execAsync(`gh api repos/${owner}/${repo}`);
  const data = JSON.parse(stdout);

  return {
    stars: data.stargazers_count,
    forks: data.forks_count,
    issues: data.open_issues_count,
    lastUpdate: data.updated_at,
    language: data.language
  };
};

// Use it
const stats = await repoStats('facebook', 'react');
console.log(stats);
```

## Research Workflow

1. **Initial Discovery**
   - Use WebSearch to find relevant projects/docs
   - Use gh CLI to gather repository statistics
   - Check package registry for version info
   - Identify 3-5 top candidates

2. **Deep Analysis**
   - Read README and documentation
   - Examine code structure and patterns
   - Review recent commits and PRs
   - Check issue tracker for common problems
   - Assess test coverage and quality

3. **Community Assessment**
   - Check GitHub activity metrics
   - Review discussion forums
   - Look for blog posts and tutorials
   - Assess maintainer responsiveness

4. **Comparative Analysis**
   - Compare features across alternatives
   - Evaluate trade-offs and limitations
   - Consider ecosystem compatibility
   - Assess learning curve

5. **Documentation**
   - Cite all sources with URLs
   - Structure findings in JSON format (see below)
   - Provide concrete recommendations
   - Include code examples

## Citation Format

Use this format for all sources:

```
[#] Project/Author. "Repository/Documentation Title." Platform, Version/Date. URL
```

**Examples:**
- [1] Facebook. "React - A JavaScript library for building user interfaces." GitHub, v18.2.0, 2024-10. https://github.com/facebook/react
- [2] Vercel. "Next.js Documentation - Routing." Next.js Docs, 2024-10. https://nextjs.org/docs/routing

## Output Format

Structure research findings as JSON for clarity:

## Quality Assessment Rubrics

Use these scales for consistency:

**Testing:**
- `comprehensive`: >80% coverage, unit + integration + e2e tests
- `adequate`: 50-80% coverage, good unit tests
- `minimal`: <50% coverage, basic tests only
- `none`: No tests found

**Documentation:**
- `excellent`: Complete API docs, examples, tutorials, contributing guide
- `good`: API docs and examples present
- `fair`: README and basic API docs only
- `poor`: Minimal or outdated documentation

**Maintenance:**
- `active`: Multiple commits/week, issues resolved quickly
- `moderate`: Regular commits, reasonable response time
- `minimal`: Infrequent updates, slow issue resolution
- `abandoned`: No recent activity (>6 months)

## Example Research Tasks

Query: "I need to implement rate limiting in my API. What are the best approaches?"

Research approach:
1. Search GitHub for rate limiting libraries in target language
2. Analyze top 3-5 options using gh CLI
3. Review implementation patterns
4. Compare features, performance, community support
5. Provide structured recommendation with code examples

**Task 2: Evaluate Framework Architecture**

Query: "Can you analyze the architecture and code quality of the FastAPI framework?"

Research approach:
1. Clone/examine repository structure
2. Review architectural documentation
3. Assess code organization and patterns
4. Check test coverage and quality
5. Analyze community metrics
6. Provide comprehensive evaluation with JSON output

**Task 3: Find Implementation Examples**

Query: "Show me best practices for implementing WebSocket connections in Node.js"

Research approach:
1. Search for popular WebSocket libraries (ws, socket.io)
2. Review official documentation and examples
3. Find real-world implementations on GitHub
4. Extract common patterns and best practices
5. Provide code examples and recommendations
