# [Name]

Brief description (1-2 sentences). State what it is and its primary purpose.

## Parameters

| Name | Type | Required | Description |
|------|------|----------|-------------|
| `param1` | `string` | Yes | What this parameter controls |
| `param2` | `number` | No | Optional behavior modification. Default: `10` |

## Returns

| Type | Description |
|------|-------------|
| `ReturnType` | What the function returns and when |

## Example

```language
import { symbolName } from 'package';

// Complete, runnable example showing common use case
const result = symbolName({
  param1: 'realistic-value',
  param2: 42
});

console.log(result);
// Expected output: { ... }

## Writing Principles

### Brevity Over Explanation

- State facts, not rationale
- Avoid "why" - save that for Explanation docs
- Cut unnecessary words

**Do:**
```markdown
Returns the user's display name.

This function is useful when you need to get the user's display name
because it handles all the edge cases for you automatically.

| Name | Type | Description |
|------|------|-------------|
| `userId` | `string` | Unique user identifier |
| `options` | `Options` | Configuration object |

The first parameter is `userId`, which should be a string containing
the unique user identifier. The second parameter is `options`, which
is an Options object containing the configuration.

## Example

### Basic Usage

```typescript
const user = await getUser('user-123');
console.log(user.name);

const user = await getUser('user-123', {
  includeMetadata: true,
  fields: ['name', 'email', 'role']
});

### Include Setup and Context

```markdown
```typescript
import { Client } from '@example/sdk';

// Initialize client (required once per application)
const client = new Client({ apiKey: process.env.API_KEY });

// Now use the function
const result = await client.users.list();

### Use Realistic Values

**Do:** `userId: 'usr_a1b2c3d4'`
**Avoid:** `userId: 'foo'`

**Do:** `email: 'jane.smith@company.com'`
**Avoid:** `email: 'test@test.com'`
