Markdown Formatter

Overview

Transforms unstructured content into clean, well-organized Markdown with proper headings, lists, code blocks, and formatting.

Instructions

When formatting content to Markdown:

1. Analyze the content to identify structure (headings, lists, code, etc.)
2. Apply hierarchy using appropriate heading levels (H1 for title, H2 for sections)
3. Format code with proper language-specific syntax highlighting
4. Create lists for related items (bullet for unordered, numbers for sequential)
5. Add tables for structured data comparisons

Formatting Rules

Headings

• H1 (#) - Document title only
• H2 (##) - Major sections
• H3 (###) - Subsections
• H4+ - Avoid unless necessary

Code Blocks

• Inline code: Single backticks for short references
• Fenced blocks: Triple backticks with language identifier

Lists

• Bullet lists: Related but unordered items
• Numbered lists: Sequential steps or ranked items
• Nested lists: Maximum 2 levels deep

Examples

Example: Format API Documentation

Input: "Document the getUser function that takes userId string and returns User object with name email and createdAt fields"

Output:

## `getUser(userId)`

Retrieves a user by their unique identifier.

### Parameters

| Name | Type | Description |
|------|------|-------------|
| `userId` | `string` | The unique user identifier |

### Returns

`User` object with the following properties:

- `name` - User's display name
- `email` - User's email address
- `createdAt` - Account creation timestamp

Guidelines

Do

• Keep line length under 100 characters
• Use blank lines to separate sections
• Prefer ATX-style headings (#) over Setext
• Use reference-style links for repeated URLs
• Include language identifier in fenced code blocks

Don't

• Use more than 3 heading levels unless necessary
• Mix heading styles in same document
• Create deeply nested lists (max 2 levels)
• Use HTML tags when Markdown suffices
