fix: Enforce min_chunk_size in RAG chunker

- Filter out chunks smaller than min_chunk_size (default 100 tokens)
- Exception: Keep all chunks if entire document is smaller than target size
- All 15 tests passing (100% pass rate)

Fixes edge case where very small chunks (e.g., 'Short.' = 6 chars) were
being created despite min_chunk_size=100 setting.

Test: pytest tests/test_rag_chunker.py -v

## Integration Architecture
### MCP Server Structure
```
MCP Server (25 tools, 6 categories)
├── Config tools (3)
├── Scraping tools (8)
├── Packaging tools (4)
├── Splitting tools (2)
├── Source tools (4)
└── Vector Database tools (4) ← NEW
├── export_to_weaviate
├── export_to_chroma
├── export_to_faiss
└── export_to_qdrant
```
### Tool Implementation Pattern
Each tool follows the FastMCP pattern:
```python
@safe_tool_decorator(description="...")
async def export_to_<target>(
skill_dir: str,
output_dir: str | None = None,
) -> str:
"""Tool docstring with args and returns."""
args = {"skill_dir": skill_dir}
if output_dir:
args["output_dir"] = output_dir
result = await export_to_<target>_impl(args)
if isinstance(result, list) and result:
return result[0].text if hasattr(result[0], "text") else str(result[0])
return str(result)
```
---
## Usage Examples
### Claude Desktop MCP Config
```json
{
"mcpServers": {
"skill-seeker": {
"command": "python",
"args": ["-m", "skill_seekers.mcp.server_fastmcp"]
}
}
}
```
### Using Vector Database Tools
**Example 1: Export to Weaviate**
```
export_to_weaviate(
skill_dir="output/react",
output_dir="output"
)
```
**Example 2: Export to Chroma with default output**
```
export_to_chroma(skill_dir="output/django")
```
**Example 3: Export to FAISS**
```
export_to_faiss(
skill_dir="output/fastapi",
output_dir="/tmp/exports"
)
```
**Example 4: Export to Qdrant**
```
export_to_qdrant(skill_dir="output/vue")
```
---
## Output Format Example
Each tool returns comprehensive instructions:
```
✅ Weaviate Export Complete!

---
## Security Measures
All workflows follow GitHub Actions security best practices:
### ✅ Safe Input Handling
1. **Environment Variables:** All inputs accessed via `env:` section
2. **No Direct Interpolation:** Never use `${{ github.event.* }}` in `run:` commands
3. **Quoted Variables:** All shell variables properly quoted
4. **Controlled Triggers:** Only `workflow_dispatch`, `schedule`, `push`, `pull_request`
### ❌ Avoided Patterns
- No `github.event.issue.title/body` usage
- No `github.event.comment.body` in run commands
- No `github.event.pull_request.head.ref` direct usage
- No untrusted commit messages in commands
### Security Documentation
Each workflow includes security comment header:
```yaml
# Security Note: This workflow uses [trigger types].
# All inputs accessed via environment variables (safe pattern).
```
---
## Usage Examples
### Manual Vector Database Export
```bash
# Export React skill to all vector databases
gh workflow run vector-db-export.yml \
-f skill_name=react \
-f targets=all
# Export Django to specific databases
gh workflow run vector-db-export.yml \
-f skill_name=django \
-f targets=weaviate,chroma
```
### Quality Analysis
```bash
# Analyze specific skill
gh workflow run quality-metrics.yml \
-f skill_dir=output/react \
-f fail_threshold=80
# On PR: Automatically triggered
# (no manual invocation needed)
```
### Scheduled Updates

### CI/CD Integration
**GitHub Actions Workflow:**
1. **Build Matrix** - 2 images (CLI + MCP)
2. **Multi-Platform** - amd64 + arm64
3. **Automated Testing** - Health checks + command tests
4. **Docker Hub** - Auto-publish on tags
5. **Caching** - GitHub Actions cache
**Triggers:**
- Push to main
- Version tags (v*)
- Pull requests (test only)
- Manual dispatch

## Usage Examples
### Quick Start
```bash
# 1. Clone repository
git clone https://github.com/your-org/skill-seekers.git
cd skill-seekers
# 2. Configure environment
cp .env.example .env
# Edit .env with your API keys
# 3. Start services
docker-compose up -d
# 4. Verify
docker-compose ps
curl http://localhost:8765/health
```
### Scrape Documentation
```bash
docker-compose run skill-seekers \
skill-seekers scrape --config /configs/react.json
```
### Export to Vector Databases
```bash
docker-compose run skill-seekers bash -c "
for target in weaviate chroma faiss qdrant; do
python -c \"
import sys
from pathlib import Path
sys.path.insert(0, '/app/src')
from skill_seekers.cli.adaptors import get_adaptor
adaptor = get_adaptor('$target')
adaptor.package(Path('/output/react'), Path('/output'))
print('✅ $target export complete')
\"
done
"
```
### Run Quality Analysis
```bash
docker-compose run skill-seekers \
python3 -c "
import sys
from pathlib import Path
sys.path.insert(0, '/app/src')
from skill_seekers.cli.quality_metrics import QualityAnalyzer
analyzer = QualityAnalyzer(Path('/output/react'))
report = analyzer.generate_report()
print(analyzer.format_report(report))
"
```

## Production Deployment
### Resource Requirements
**Minimum:**
- CPU: 2 cores
- RAM: 2GB
- Disk: 5GB
**Recommended:**
- CPU: 4 cores
- RAM: 4GB
- Disk: 20GB (with vector DBs)
### Security Hardening
1. **Secrets Management**
```bash
# Docker secrets
echo "sk-ant-key" | docker secret create anthropic_key -
```
2. **Resource Limits**
```yaml
services:
mcp-server:
deploy:
resources:
limits:
cpus: '2.0'
memory: 2G
```
3. **Read-Only Filesystem**
```yaml
services:
mcp-server:
read_only: true
tmpfs:
- /tmp
```
### Monitoring
**Health Checks:**
```bash
# Check services
docker-compose ps
# Detailed health
docker inspect skill-seekers-mcp | grep Health
```
**Logs:**
```bash
# Stream logs
docker-compose logs -f
# Export logs
docker-compose logs > logs.txt
```
**Metrics:**
```bash
# Resource usage
docker stats
# Per-service metrics
docker-compose top
```

2. **Secrets via env** - No hardcoded keys
3. **Read-only support** - Configurable
4. **Resource limits** - Prevent DoS
### ✅ Reliability
1. **Health checks** - All services
2. **Auto-restart** - unless-stopped
3. **Volume persistence** - Named volumes
4. **Graceful shutdown** - SIGTERM handling
### ✅ Developer Experience
1. **One-command start** - `docker-compose up`
2. **Hot reload** - Volume mounts
3. **Easy configuration** - .env file
4. **Comprehensive docs** - 650+ line guide

## Troubleshooting Guide
### Common Issues
1. **Port Already in Use**
```bash
# Check what's using the port
lsof -i :8765
# Use different port
MCP_PORT=8766 docker-compose up -d
```
2. **Permission Denied**
```bash
# Fix ownership
sudo chown -R $(id -u):$(id -g) data/ output/
```
3. **Out of Memory**
```bash
# Increase limits
docker-compose up -d --scale mcp-server=1 --memory=4g
```
4. **Slow Build**
```bash
# Enable BuildKit
export DOCKER_BUILDKIT=1
docker build -t skill-seekers:local .
```
