# Manpage Schema v1.0

**Schema ID:** `https://markitect.dev/schemas/manpage/v1`
**Version:** 1.0.0
**Status:** Stable
**Created:** 2026-01-04
**Document Types:** Manual pages, CLI documentation

## Overview

This schema validates Unix/Linux manual page documentation following standard conventions. Manual pages (man pages) are the traditional form of documentation for Unix commands and system calls.

## Typical Structure

A well-formed manual page includes:

1. **NAME** - Command name and one-line description
2. **SYNOPSIS** - Command syntax showing all options
3. **DESCRIPTION** - Detailed explanation of what the command does
4. **OPTIONS** - Description of each command-line option
5. **EXAMPLES** - Practical usage examples
6. **SEE ALSO** - Related commands or documentation

## Usage

### Validate a Manpage

```bash
markitect validate mycommand.1.md --schema manpage-schema-v1
```

### Generate Manpage Template

```bash
markitect generate-stub manpage-schema-v1.json --output newcommand.1.md
```

### Refine Existing Schema

```bash
markitect schema-refine manpage-schema-v1.json --loosen-counts
```

## Examples

Complete examples can be found in:
- [examples/manpages/markdown-schema-validation.1.md](../manpages/markdown-schema-validation.1.md)
