## JSDoc Code Documentation

**ALWAYS document public APIs with complete JSDoc:**

### Function Documentation
```typescript
/**
 * Fetches members of the European Parliament by party group.
 * 
 * Makes authenticated request to EP API and transforms response into
 * standardized Member format with caching support.
 * 
 * @param partyGroupId - The ID of the party group (e.g., "PPE", "S&D")
 * @param options - Optional query parameters for filtering
 * @param options.country - Filter by member state (ISO 3166-1 alpha-2)
 * @param options.active - Filter by active status (default: true)
 * @returns Array of Member objects with full details
 * @throws {APIError} When API request fails
 * @throws {ValidationError} When partyGroupId is invalid
 * 
 * @example
 * ```typescript
 * const members = await getMembersByPartyGroup("PPE", {
 *   country: "DE",
 *   active: true
 * });
 * console.log(`Found ${members.length} members`);
 * ```
 * 
 * @see {@link Member} for member object structure
 * @see {@link PartyGroup} for party group details
 */
export async function getMembersByPartyGroup(
  partyGroupId: string,
  options?: { country?: string; active?: boolean }
): Promise<Member[]> {
  // Implementation...
}
```

### Interface Documentation
```typescript
/**
 * Represents a Member of the European Parliament.
 * 
 * Contains biographical data, political affiliation, and parliamentary activities.
 * All dates are in ISO 8601 format. IDs are stable across API versions.
 * 
 * @example
 * ```typescript
 * const member: Member = {
 *   id: 12345,
 *   fullName: "Jane Doe",
 *   country: "DE",
 *   partyGroup: "PPE",
 *   active: true,
 *   termStart: "2019-07-02"
 * };
 * ```
 */
export interface Member {
  /** Unique identifier (persistent across terms) */
  id: number;
  
  /** Full name in official format */
  fullName: string;
  
  /** Country code (ISO 3166-1 alpha-2) */
  country: string;
  
  /** Political party group code */
  partyGroup: string;
  
  /** Current active status */
  active: boolean;
  
  /** Term start date (ISO 8601) */
  termStart: string;
}
```

## API Documentation

- Document public APIs and exported functions
- Include parameter types, return types, and examples
- Note breaking changes and migration guides
- Maintain changelog with semantic versioning
- Provide usage examples for complex APIs

## MCP Server Documentation

**Document MCP server tools, resources, and prompts:**

### Tool Documentation Pattern
```markdown
## Tools

### `get_members`

Retrieves Members of the European Parliament with filtering options.

**Parameters:**
- `filters` (object, optional): Filtering criteria
  - `partyGroup` (string): Filter by party group code
  - `country` (string): Filter by country (ISO 3166-1 alpha-2)
  - `active` (boolean): Filter by active status

**Returns:** Array of Member objects

**Example:**
```json
{
  "name": "get_members",
  "arguments": {
    "filters": {
      "partyGroup": "PPE",
      "country": "FR",
      "active": true
    }
  }
}
```

**Response:**
```json
{
  "members": [
    {
      "id": 12345,
      "fullName": "Jean Dupont",
      "country": "FR",
      "partyGroup": "PPE"
    }
  ]
}
```
```

## ISMS Security Documentation

**MUST align documentation with Hack23 ISMS policies:**

### Security Policy Documentation
Follow the structure from `SECURITY.md` and reference policies:

```markdown

## Mermaid Diagram Patterns

**Use Mermaid for visual documentation:**

### MCP Server Architecture
```mermaid
graph TB
    Client[MCP Client] --> Server[EP MCP Server]
    Server --> API[European Parliament API]
    Server --> Cache[Response Cache]
    
    subgraph "MCP Server"
        Tools[Tools Layer]
        Resources[Resources Layer]
        Prompts[Prompts Layer]
    end
    
    Server --> Tools
    Server --> Resources
    Server --> Prompts
    
    Tools --> API
    Resources --> API
    
    style Server fill:#4CAF50,stroke:#2E7D32,color:#fff
    style API fill:#2196F3,stroke:#1565C0,color:#fff
```

## Remember

**ALWAYS:**
- ✅ Use complete JSDoc for public APIs (@param, @returns, @throws, @example)
- ✅ Include tested, working code examples
- ✅ Create Mermaid diagrams for architecture and flows
- ✅ Reference Hack23 ISMS policies for security documentation
- ✅ Use proper heading hierarchy (H1 → H2 → H3, no skips)
- ✅ Specify language in code blocks (\`\`\`typescript)
- ✅ Verify all links work before committing
- ✅ Keep docs synchronized with code changes

**NEVER:**
- ❌ Skip JSDoc for public APIs
- ❌ Provide untested code examples
- ❌ Omit ISMS policy references in security docs
- ❌ Skip heading levels (H1 → H3)
- ❌ Use unlabeled code blocks
- ❌ Commit broken links
- ❌ Let docs become stale

---

**Your Mission:** Create clear, comprehensive, maintainable documentation that includes complete JSDoc with working examples, uses Mermaid diagrams for visual representation, and aligns security documentation with Hack23 ISMS policies for professional, accessible technical documentation.
