# Core Concepts

> **Skill Seekers v3.6.0**  
> **Understanding how Skill Seekers works**

---

## Overview

Skill Seekers transforms documentation, code, and content into **structured knowledge assets** that AI systems can use effectively. It supports **18 source types** including documentation sites, GitHub repos, PDFs, videos, notebooks, wikis, and more.

```
Raw Content → Skill Seekers → AI-Ready Skill
     ↓                              ↓
  (docs, code, PDFs,          (SKILL.md +
   videos, notebooks,          references)
   wikis, feeds, etc.)
```

## What is a Skill?

A **skill** is a structured knowledge package containing:

```
output/my-skill/
├── SKILL.md              # Main file (400+ lines typically)
├── references/           # Categorized content
│   ├── index.md         # Navigation
│   ├── getting_started.md
│   ├── api_reference.md
│   └── ...
├── .skill-seekers/      # Metadata
└── assets/              # Images, downloads
```

## The Workflow

### Phase 1: Ingest

```
┌─────────────┐     ┌──────────────┐
│   Source    │────▶│   Scraper    │
│ (URL/repo/  │     │ (extracts    │
│  PDF/local) │     │  content)    │
└─────────────┘     └──────────────┘
```

- Detects source type automatically
- Crawls and downloads content
- Respects rate limits
- Extracts text, code, metadata

---

### Phase 2: Structure

```
┌──────────────┐     ┌──────────────┐
│   Raw Data   │────▶│   Builder    │
│ (pages/files/│     │ (organizes   │
│  commits)    │     │  by category)│
└──────────────┘     └──────────────┘
```

- Categorizes content by topic
- Extracts code examples
- Builds navigation structure
- Creates reference files

---

### Phase 3: Enhance (Optional)

```
┌──────────────┐     ┌──────────────┐
│   SKILL.md   │────▶│  Enhancer    │
│  (basic)     │     │ (AI improves │
│              │     │  quality)    │
└──────────────┘     └──────────────┘
```

- AI reviews and improves content
- Adds examples and patterns
- Fixes formatting
- Enhances navigation

**Modes:**
- **API:** Uses Claude API (fast, costs ~$0.10-0.30)
- **LOCAL:** Uses Claude Code (free, requires Claude Code Max)

---

### Phase 4: Package

```
┌──────────────┐     ┌──────────────┐
│   Skill Dir  │────▶│   Packager   │
│ (structured  │     │ (creates     │
│  content)    │     │  platform    │
│              │     │  format)     │
└──────────────┘     └──────────────┘
```

- Formats for target platform
- Creates archives (ZIP, tar.gz)
- Optimizes for size
- Validates structure

---

### Phase 5: Upload (Optional)

```
┌──────────────┐     ┌──────────────┐
│   Package    │────▶│   Platform   │
│ (.zip/.tar)  │     │ (Claude/     │
│              │     │  Gemini/etc) │
└──────────────┘     └──────────────┘
```

- Uploads to target platform
- Configures settings
- Returns skill ID/URL

---

## Enhancement Levels

Control how much AI enhancement is applied:

| Level | What Happens | Use Case |
|-------|--------------|----------|
| **0** | No enhancement | Fast scraping, manual review |
| **1** | SKILL.md only | Basic improvement |
| **2** | + architecture/config | **Recommended** - good balance |
| **3** | Full enhancement | Maximum quality, takes longer |

**Default:** Level 2

```bash
# Skip enhancement (fastest)
skill-seekers create <source> --enhance-level 0

# Full enhancement (best quality)
skill-seekers create <source> --enhance-level 3
```

---

## Target Platforms

Package skills for different AI systems:

| Platform | Format | Use |
|----------|--------|-----|
| **Claude AI** | ZIP + YAML | Claude Code, Claude API |
| **Gemini** | tar.gz | Google Gemini |
| **OpenAI** | ZIP + Vector | ChatGPT, Assistants API |
| **LangChain** | Documents | RAG pipelines |
| **LlamaIndex** | TextNodes | Query engines |
| **ChromaDB** | Collection | Vector search |
| **Weaviate** | Objects | Vector database |
| **Cursor** | .cursorrules | IDE AI assistant |
| **Windsurf** | .windsurfrules | IDE AI assistant |

---

## Configuration

### Simple (Auto-Detect)

```bash
# Just provide the source
skill-seekers create https://docs.react.dev/
```

### Preset Configs

```bash
# Use predefined configuration
skill-seekers create --config react
```

**Available presets:** `react`, `vue`, `django`, `fastapi`, `godot`, etc.

### Custom Config

```bash
# Create custom config
cat > configs/my-docs.json << 'EOF'
{
  "name": "my-docs",
  "base_url": "https://docs.example.com/",
  "max_pages": 200
}
EOF

skill-seekers create --config configs/my-docs.json
```

See [Config Format](../reference/CONFIG_FORMAT.md) for full specification.

---

## Multi-Source Skills

Combine multiple sources into one skill:

```bash
# Create unified config
cat > configs/my-project.json << 'EOF'
{
  "name": "my-project",
  "sources": [
    {"type": "docs", "base_url": "https://docs.example.com/"},
    {"type": "github", "repo": "owner/repo"},
    {"type": "pdf", "pdf_path": "manual.pdf"}
  ]
}
EOF

# Run unified scraping
skill-seekers create --config configs/my-project.json
```

**Benefits:**
- Single skill with complete context
- Automatic conflict detection
- Cross-referenced content

---

## Caching and Resumption

### How Caching Works

```
First scrape:    Downloads all pages → saves to output/{name}_data/
Second scrape:   Reuses cached data → fast rebuild
```

### Skip Scraping

```bash
# Use cached data, just rebuild
skill-seekers create --config react --skip-scrape
```

### Resume Interrupted Jobs

```bash
# List resumable jobs
skill-seekers resume --list

# Resume specific job
skill-seekers resume job-abc123
```

---

## Rate Limiting

Be respectful to servers:

```bash
# Default: 0.5 seconds between requests
skill-seekers create <source>

# Faster (for your own servers)
skill-seekers create <source> --rate-limit 0.1

# Slower (for rate-limited sites)
skill-seekers create <source> --rate-limit 2.0
```

**Why it matters:**
- Prevents being blocked
- Respects server resources
- Good citizenship

---

## Key Takeaways

1. **Skills are structured knowledge** - Not just raw text
2. **Auto-detection works** - Usually don't need custom configs
3. **Enhancement improves quality** - Level 2 is the sweet spot
4. **Package once, use everywhere** - Same skill, multiple platforms
5. **Cache saves time** - Rebuild without re-scraping
