## Overview

Skill Seekers uses JSON configuration files to define scraping targets. There are two types:

| Type | Use Case | File |
|------|----------|------|
| **Single-Source** | One source (docs, GitHub, PDF, or local) | `*.json` |
| **Unified** | Multiple sources combined | `*-unified.json` |

## Selectors

CSS selectors for content extraction from HTML:

```json
{
  "selectors": {
    "main_content": "article",
    "title": "h1",
    "code_blocks": "pre code",
    "navigation": "nav.sidebar",
    "breadcrumbs": "nav[aria-label='breadcrumb']",
    "next_page": "a[rel='next']",
    "prev_page": "a[rel='prev']"
  }
}
```

### Default Selectors

If not specified, these defaults are used:

| Element | Default Selector |
|---------|-----------------|
| `main_content` | `article, main, .content, #content, [role='main']` |
| `title` | `h1, .page-title, title` |
| `code_blocks` | `pre code, code[class*="language-"]` |
| `navigation` | `nav, .sidebar, .toc` |

---

## Categories

Map URL patterns to content categories:

```json
{
  "categories": {
    "getting_started": [
      "intro", "tutorial", "quickstart", 
      "installation", "getting-started"
    ],
    "core_concepts": [
      "concept", "fundamental", "architecture",
      "principle", "overview"
    ],
    "api_reference": [
      "reference", "api", "method", "function",
      "class", "interface", "type"
    ],
    "guides": [
      "guide", "how-to", "example", "recipe",
      "pattern", "best-practice"
    ],
    "advanced": [
      "advanced", "expert", "performance",
      "optimization", "internals"
    ]
  }
}
```

Categories appear as sections in the generated SKILL.md.

---

## URL Patterns

Control which URLs are included or excluded:

```json
{
  "url_patterns": {
    "include": [
      "/docs/",
      "/guide/",
      "/api/",
      "/reference/"
    ],
    "exclude": [
      "/blog/",
      "/news/",
      "/community/",
      "/search",
      "?print=1",
      "/_static/",
      "/_images/"
    ]
  }
}
```

### Pattern Rules

- Patterns are matched against the URL path
- Use `*` for wildcards: `/api/v*/`
- Use `**` for recursive: `/docs/**/*.html`
- Exclude takes precedence over include

---

  "selectors": {
    "main_content": "article",
    "title": "h1",
    "code_blocks": "pre code"
  },
  "url_patterns": {
    "include": ["/learn/", "/reference/", "/blog/"],
    "exclude": ["/community/", "/search"]
  },
  "categories": {

  "analysis_depth": "comprehensive",
  "extract_api": true,
  "extract_test_examples": true
}
```

## Validation

Validate your config before scraping:

```bash
# Using CLI
skill-seekers scrape --config my-config.json --dry-run

# Using MCP tool
validate_config({"config": "my-config.json"})
```
