## Claude.ai Projects Installation

To use these skills in Claude.ai (web interface), export the skill files for upload:

```bash
./install.sh --claude-ai
```

This displays available files in `claude-project/` and optionally copies them to a convenient location.

## User Guide

### Basic Workflow

**Step 1: Discover References**
```
/reference-discovery Claude's system prompt best practices
```
Claude searches the web, validates sources, and creates a manifest of URLs to crawl.

**Step 2: Crawl Content**
```
/web-crawler https://docs.anthropic.com --max-pages 50
```
The crawler automatically selects the best backend based on site characteristics.

**Step 3: Store in Repository**
```
/content-repository store
```
Documents are saved to MySQL with deduplication and version tracking.

**Step 4: Distill Content**
```
/content-distiller all-pending
```
Claude summarizes, extracts key concepts, and creates structured content.

**Step 5: Quality Review**
```
/quality-reviewer all-pending --auto-approve
```
Automated QA scoring determines: approve, refactor, deep research, or reject.

**Step 6: Export**
```
/markdown-exporter project_files --topic prompt-engineering
```
Generates markdown files organized by topic with cross-references.

### Example Prompts

| Task | Command |
|------|---------|
| **Discover sources** | `/reference-discovery MCP server development` |
| **Crawl URL** | `/web-crawler https://docs.anthropic.com` |
| **Check repository** | `/content-repository stats` |
| **Distill document** | `/content-distiller 42` |
| **Review quality** | `/quality-reviewer all-pending` |
| **Export files** | `/markdown-exporter project_files` |

### Crawler Selection

The system automatically selects the optimal crawler:

| Site Type | Crawler | When Auto-Selected |
|-----------|---------|-------------------|
| SPAs/Dynamic | **Firecrawl MCP** | React, Vue, Angular sites (default) |
| Small docs sites | **Node.js** | ≤50 pages, static HTML |
| Technical docs | **Python aiohttp** | ≤200 pages, needs SEO data |
| Enterprise sites | **Scrapy** | >200 pages, multi-domain |

Override with explicit request:
```
/web-crawler https://example.com --crawler firecrawl
```

### Quality Review Decisions

| Score | Decision | What Happens |
|-------|----------|--------------|
| ≥ 0.85 | **Approve** | Ready for export |
| 0.60-0.84 | **Refactor** | Re-distill with feedback |
| 0.40-0.59 | **Deep Research** | Gather more sources |
| < 0.40 | **Reject** | Archive (low quality) |

### Database Queries

Check your reference library status:

```bash
# Source credentials
source ~/.reference-curator.env

# Count documents by status
mysql -h $MYSQL_HOST -u $MYSQL_USER -p"$MYSQL_PASSWORD" reference_library -e "
  SELECT crawl_status, COUNT(*) as count
  FROM documents GROUP BY crawl_status;"

# View pending reviews
mysql -h $MYSQL_HOST -u $MYSQL_USER -p"$MYSQL_PASSWORD" reference_library -e "
  SELECT * FROM v_pending_reviews;"

# View export-ready documents
mysql -h $MYSQL_HOST -u $MYSQL_USER -p"$MYSQL_PASSWORD" reference_library -e "
  SELECT * FROM v_export_ready;"
```

### Output Formats

**For Claude Projects:**
```
~/reference-library/exports/
├── INDEX.md                 # Master index with all topics
└── prompt-engineering/      # Topic folder
    ├── _index.md            # Topic overview
    ├── system-prompts.md    # Individual document
    └── chain-of-thought.md
```

**For Fine-tuning (JSONL):**
```json
{"messages": [{"role": "system", "content": "..."}, {"role": "user", "content": "..."}, {"role": "assistant", "content": "..."}]}
```

# Storage location
export REFERENCE_LIBRARY_PATH="~/reference-library"

# Crawler selection
export DEFAULT_CRAWLER="firecrawl"  # firecrawl, nodejs, aiohttp, scrapy
```

### Database (`~/.config/reference-curator/db_config.yaml`)

```yaml
mysql:
  host: ${MYSQL_HOST:-localhost}
  port: ${MYSQL_PORT:-3306}
  database: reference_library
  user: ${MYSQL_USER}
  password: ${MYSQL_PASSWORD}
```

### Crawlers (`~/.config/reference-curator/crawl_config.yaml`)

```yaml
default_crawler: ${DEFAULT_CRAWLER:-firecrawl}

rate_limit:
  requests_per_minute: 20
  concurrent_requests: 3

default_options:
  timeout: 30000
  max_depth: 3
  max_pages: 100
```

## Troubleshooting

### MySQL Connection Failed

```bash
# Check MySQL is running
brew services list | grep mysql   # macOS
systemctl status mysql            # Linux

# Start MySQL
brew services start mysql         # macOS
sudo systemctl start mysql        # Linux

# Verify credentials
source ~/.reference-curator.env
mysql -h $MYSQL_HOST -u $MYSQL_USER -p"$MYSQL_PASSWORD" -e "SELECT 1"
```

### Commands Not Found

```bash
# Check commands are registered
ls -la ~/.claude/commands/

# Re-run installer to fix
./install.sh
```

### Crawler Timeout

For slow sites, increase timeout in `~/.config/reference-curator/crawl_config.yaml`:
```yaml
default_options:
  timeout: 60000  # 60 seconds
```

### Skills Not Loading

```bash
# Check symlinks exist
ls -la ~/.claude/skills/

# Re-run installer
./install.sh --uninstall
./install.sh
```

### Database Schema Outdated

```bash
# Re-apply schema (preserves data with IF NOT EXISTS)
source ~/.reference-curator.env
mysql -h $MYSQL_HOST -u $MYSQL_USER -p"$MYSQL_PASSWORD" reference_library < shared/schema.sql
```
