# Three-Stream GitHub Architecture - Completion Summary

**Date**: January 8, 2026
**Status**: ✅ **ALL PHASES COMPLETE (1-6)**
**Total Time**: 28 hours (2 hours under budget!)

---

## ✅ PHASE 1: GitHub Three-Stream Fetcher (COMPLETE)

**Estimated**: 8 hours | **Actual**: 8 hours | **Tests**: 24/24 passing

**Created Files:**
- `src/skill_seekers/cli/github_fetcher.py` (340 lines)
- `tests/test_github_fetcher.py` (24 tests)

**Key Deliverables:**
- ✅ Data classes (CodeStream, DocsStream, InsightsStream, ThreeStreamData)
- ✅ GitHubThreeStreamFetcher class
- ✅ File classification algorithm (code vs docs)
- ✅ Issue analysis algorithm (problems vs solutions)
- ✅ HTTPS and SSH URL support

---

## ✅ PHASE 2: Unified Codebase Analyzer (COMPLETE)

analyzer = UnifiedCodebaseAnalyzer()
result = analyzer.analyze(
    source="https://github.com/facebook/react",
    depth="basic",
    fetch_github_metadata=True
)

print(f"Files: {len(result.code_analysis['files'])}")
print(f"README: {result.github_docs['readme'][:100]}")
print(f"Stars: {result.github_insights['metadata']['stars']}")
```

### Example 2: C3.x Analysis with All Streams

```python
# Deep C3.x analysis (20-60 minutes)
result = analyzer.analyze(
    source="https://github.com/jlowin/fastmcp",
    depth="c3x",
    fetch_github_metadata=True
)

# Access code stream (C3.x analysis)
print(f"Patterns: {len(result.code_analysis['c3_1_patterns'])}")
print(f"Examples: {result.code_analysis['c3_2_examples_count']}")
print(f"Guides: {len(result.code_analysis['c3_3_guides'])}")
print(f"Configs: {len(result.code_analysis['c3_4_configs'])}")
print(f"Architecture: {len(result.code_analysis['c3_7_architecture'])}")

# Access docs stream
print(f"README: {result.github_docs['readme'][:100]}")

# Access insights stream
print(f"Common problems: {len(result.github_insights['common_problems'])}")
print(f"Known solutions: {len(result.github_insights['known_solutions'])}")
```

### Example 3: Router Generation with GitHub

```python
from skill_seekers.cli.generate_router import RouterGenerator
from skill_seekers.cli.github_fetcher import GitHubThreeStreamFetcher

# Fetch GitHub repo with three streams
fetcher = GitHubThreeStreamFetcher("https://github.com/jlowin/fastmcp")
three_streams = fetcher.fetch()

# Generate router with GitHub integration
generator = RouterGenerator(
    ['configs/fastmcp-oauth.json', 'configs/fastmcp-async.json'],
    github_streams=three_streams
)

skill_md = generator.generate_skill_md()
# Result includes: repo stats, README quick start, common issues
```
