E2E Tests for All Architecture Document Scenarios

Tests all 3 configuration examples from C3_x_Router_Architecture.md:
1. GitHub with Three-Stream (Lines 2227-2253)
2. Documentation + GitHub Multi-Source (Lines 2255-2286)
3. Local Codebase (Lines 2287-2310)

Validates:
- All 3 streams present (Code, Docs, Insights)
- C3.x components loaded (patterns, examples, guides, configs, architecture)
- Router generation with GitHub metadata
- Sub-skill generation with issue sections
- Quality metrics (size, content, GitHub integration)

# FastMCP - Overview

## Repository Info
**Repository:** https://github.com/jlowin/fastmcp
**Stars:** ⭐ 1,234 | **Language:** Python | **Open Issues:** 12

FastMCP is a Python framework for building MCP servers with OAuth support.

## When to Use This Skill

Use this skill when you want an overview of FastMCP.

## Quick Start (from README)

Install with pip:
```bash
pip install fastmcp
```

Create a server:
```python
from fastmcp import FastMCP
app = FastMCP("my-server")
```

Run the server:
```bash
python server.py
```

## Common Issues (from GitHub)

Based on analysis of GitHub issues:

1. **OAuth setup fails** (Issue #42, 15 comments)
   - See `fastmcp-oauth` skill for solution

2. **Async tools not working** (Issue #38, 8 comments)
   - See `fastmcp-async` skill for solution

3. **Testing with pytest** (Issue #35, 6 comments)
   - See `fastmcp-testing` skill for solution

4. **Config file location** (Issue #30, 5 comments)
   - Check documentation for config paths

5. **Build failure on Windows** (Issue #25, 7 comments)
   - Known issue, see workaround in issue

## Choose Your Path

**Need OAuth?** → Use `fastmcp-oauth` skill
**Building async tools?** → Use `fastmcp-async` skill
**Writing tests?** → Use `fastmcp-testing` skill
