Tech Ecosystem Analyzer

Overview

This skill enables systematic, data-driven analysis of technology ecosystems through a combination of web research, GitHub API data collection, quantitative scoring, and comprehensive documentation. It transforms subjective technology selection into objective, metrics-based decision-making.

Unlike simple web research, this skill produces:

• •Quantitative rankings based on GitHub metrics (stars, forks, growth rates)
• •Automated data collection via custom Python scripts
• •Dual output: raw data (JSON) + analysis report (Markdown)
• •Comparative analysis with scoring algorithms
• •Trend predictions and actionable recommendations

When to Use This Skill

Use this skill when users request any of the following:

• •Technology stack evaluation: "Compare React state management libraries"
• •Ecosystem trend analysis: "What are the latest trends in the Python data science ecosystem?"
• •Library/framework comparison: "Analyze Vue.js vs React vs Svelte with data"
• •Tool selection research: "Which GraphQL client should we use?"
• •Open source project evaluation: "Compare testing frameworks for JavaScript"
• •Technology adoption decisions: "Should we migrate from Redux to Zustand?"
• •Competitive technical analysis: "Compare popular CI/CD tools"

Key indicators:

• •User requests comparison of multiple (3+) libraries/tools
• •Request implies need for quantitative data (GitHub stats, growth rates)
• •User wants trend analysis or future predictions
• •Decision-making context (choosing between options)
• •Request mentions "latest", "trending", "popular", "best"

Do NOT use this skill when:

• •Analyzing a single library/tool (use web-research-documenter instead)
• •No quantitative comparison needed
• •Focus is purely qualitative (best practices, tutorials)

Workflow

Follow this systematic five-step workflow for ecosystem analysis:

Step 1: Clarify Scope and Output Requirements

Before starting analysis, confirm with the user:

1. •Which libraries/frameworks/tools to analyze (minimum 3 recommended)
2. •Output directory location for results
3. •Any specific metrics of interest (performance, bundle size, etc.)

Example interaction:

User: "Analyze React state management trends"
Claude: "I'll analyze the React state management ecosystem. I recommend including:
- Redux (traditional standard)
- Zustand (modern lightweight)
- Jotai (atomic pattern)
- TanStack Query (server state)
- Recoil (if desired)

Where would you like me to save the analysis results?"

Step 2: Conduct Multi-Angle Web Research

Execute 2-3 complementary web searches to gather comprehensive context about the ecosystem:

Search strategy:

• •Search 1 (Broad): Overall ecosystem trends and library names
  • •Example: "React state management 2024 2025 Redux Zustand Jotai"
• •Search 2 (Comparative): Direct comparisons and decision guides
  • •Example: "Redux vs Zustand vs Jotai comparison 2024"
• •Search 3 (Version-specific): Latest updates and features
  • •Example: "Redux Toolkit Zustand latest version features 2024"

Tool usage:

// Execute searches in parallel
mcp-server-search__web_search(query="[broad ecosystem query]", max_results=10)
mcp-server-search__web_search(query="[comparison query]", max_results=10)
mcp-server-search__web_search(query="[version-specific query]", max_results=10)

What to extract from search results:

• •Current version numbers and release dates
• •Key features and differentiators
• •Community sentiment and adoption trends
• •Migration patterns (what people are moving from/to)
• •Integration patterns with other tools

Step 3: Generate GitHub Data Collection Script

Create a Python script to automate GitHub API data collection and analysis. Use the template in scripts/collect_github_data.py as a foundation.

Script must include:

1. •Library definitions with GitHub repo paths
2. •GitHub API fetching function
3. •Popularity score calculation (weighted algorithm)
4. •Growth rate estimation
5. •JSON data export
6. •Console output with rankings

Key metrics to collect:

• •Stars (primary popularity indicator)
• •Forks (community contribution level)
• •Open issues (maintenance health)
• •Last update timestamp (activity level)
• •Watchers
• •Creation date (project age)
• •License, language, description

Popularity scoring algorithm: Use weighted scoring to normalize and compare different-sized projects:

weights = {
    "stars": 0.4,        # Primary popularity indicator
    "forks": 0.2,        # Community engagement
    "watchers": 0.1,     # Active interest
    "recent_activity": 0.3  # Maintenance health
}

# Normalize against realistic maximums for the ecosystem
star_score = min(stars / max_stars, 1.0) * weights["stars"]
# ... similar for other metrics

total_score = sum(all_scores) * 100  # Scale to 0-100

Growth rate calculation:

age_days = (now - created_date).days
avg_stars_per_day = stars / max(age_days, 1)

if avg_stars_per_day > 50: return "Very High"
elif avg_stars_per_day > 20: return "High"
elif avg_stars_per_day > 5: return "Medium"
else: return "Low"

File location: Save script to: {output_directory}/collect_github_data.py

Step 4: Execute Data Collection

Run the Python script using desktop-commander process execution:

desktop-commander__start_process(
    command=f"cd {output_directory} && python3 collect_github_data.py",
    timeout_ms=30000
)

Expected outputs:

1. •Console summary with rankings
2. •JSON file: {output_directory}/[ecosystem]_data.json

Verify data quality:

• •All libraries successfully fetched
• •No API rate limit errors
• •Popularity scores calculated
• •JSON properly formatted

Step 5: Synthesize Comprehensive Analysis Report

Create a detailed Markdown report using the template structure below. Write in chunks (25-30 lines per write_file call) using desktop-commander.

Report structure (see references/report_template.md for full template):

Advanced Techniques

Handling Large Ecosystems (10+ libraries)

For ecosystems with many options:

1. •Phase 1: Analyze top 5-7 by popularity
2. •Phase 2: Deep-dive into top 3 based on Phase 1
3. •Optional Phase 3: Niche/emerging options

Custom Scoring Algorithms

Adjust weights based on ecosystem characteristics:

• •Mature ecosystems (e.g., React): Weight recent activity higher
• •Emerging ecosystems (e.g., Deno): Weight growth rate higher
• •Enterprise contexts: Weight fork count and open issues higher

Multi-Dimensional Analysis

Beyond GitHub metrics, consider:

• •Bundle size: For frontend libraries
• •Performance benchmarks: For frameworks
• •TypeScript support: For modern projects
• •Framework integrations: For specific contexts
• •Learning curve: For team adoption

Include these in report if relevant to user's context.

Trend Prediction Methodology

Base predictions on:

1. •Growth rates: Extrapolate current trajectories
2. •Community signals: Reddit/Twitter/HN mentions
3. •Corporate backing: Company sponsorships
4. •Ecosystem momentum: Integration with popular tools
5. •Developer sentiment: Issue discussions, migrations

Assign probability estimates to scenarios:

• •90%+ = Highly confident
• •70-90% = Likely
• •50-70% = Moderate confidence
• •<50% = Speculative

Common Pitfalls to Avoid

❌ Analyzing outdated data: Always collect fresh GitHub stats ❌ Ignoring context: Same library isn't best for all projects ❌ Pure metrics bias: High stars ≠ best choice for every case ❌ Missing the "why": Explain rationale, don't just rank ❌ Incomplete web research: Multiple search angles required ❌ Generic recommendations: Tailor to project size/type ❌ No actionable steps: Analysis must guide decisions

Example Usage Patterns

Pattern 1: New Project Technology Selection

User: "We're starting a new React project. Help us choose state management."
→ Analyze: Redux, Zustand, Jotai, TanStack Query, Recoil
→ Emphasize: Learning curve, bundle size, team onboarding
→ Recommendation: Project size-based decision framework

Pattern 2: Migration Evaluation

User: "Should we migrate from Redux to Zustand?"
→ Analyze: Redux, Redux Toolkit, Zustand (focused comparison)
→ Emphasize: Migration effort, breaking changes, ROI
→ Recommendation: Go/no-go decision with migration strategy

Pattern 3: Ecosystem Monitoring

User: "What are the latest Python ML library trends?"
→ Analyze: TensorFlow, PyTorch, JAX, scikit-learn, etc.
→ Emphasize: Recent updates, community shifts, future direction
→ Recommendation: When to adopt new tools vs. stay current

Pattern 4: Competitive Analysis

User: "Compare GraphQL clients for React"
→ Analyze: Apollo, urql, Relay, graphql-request, etc.
→ Emphasize: Feature comparison, performance, bundle size
→ Recommendation: Use-case specific (simple vs. complex apps)

Integration with Other Skills

This skill complements:

• •web-research-documenter: Use for single-library deep dives
