**Version**: 1.42.0  
**Last Updated**: 2026-02-11  
**Spec Type**: Example - CLI Feature

## Overview

This Spec demonstrates how to add a new CLI command to kse. We'll implement `kse export` command that exports Spec data in various formats (JSON, Markdown, HTML).

**Learning Points:**
- CLI command structure
- Argument parsing
- File I/O operations
- Output formatting
- Error handling in CLI

## User Stories

### US-1: Export Spec as JSON
**As a** developer  
**I want to** export a Spec as JSON  
**So that** I can process it programmatically

**Acceptance Criteria:**
- WHEN I run `kse export 01-00-feature --format json` THEN I get a JSON file
- WHEN export succeeds THEN I see success message with file path
- WHEN Spec doesn't exist THEN I see error message

### US-2: Export Spec as Markdown
**As a** developer  
**I want to** export a Spec as single Markdown file  
**So that** I can share it easily

**Acceptance Criteria:**
- WHEN I run `kse export 01-00-feature --format md` THEN I get a Markdown file
- WHEN I don't specify format THEN Markdown is default
- WHEN export succeeds THEN file contains all three Spec documents

### US-3: Export Spec as HTML
**As a** developer  
**I want to** export a Spec as HTML  
**So that** I can view it in a browser

**Acceptance Criteria:**
- WHEN I run `kse export 01-00-feature --format html` THEN I get an HTML file
- WHEN I open HTML THEN it has proper styling
- WHEN HTML includes code blocks THEN they have syntax highlighting

## Functional Requirements

### FR-1: Command Interface
```bash
kse export <spec-name> [options]

Options:

  --include-meta  Include metadata in export [default: true]
```

### FR-2: JSON Export
- Export structure: `{ name, requirements, design, tasks, metadata }`
- Include file paths and timestamps
- Pretty-print JSON (2-space indentation)

### FR-3: Markdown Export
- Combine requirements.md, design.md, tasks.md
- Add table of contents
- Add metadata header
- Preserve formatting

### FR-4: HTML Export
- Convert Markdown to HTML
- Add CSS styling
- Add syntax highlighting for code blocks
- Make it printable

## Non-Functional Requirements

### NFR-1: Performance
- Export completes in < 1 second for typical Spec
- Handle large Specs (> 10MB) gracefully

### NFR-2: Error Handling
- Clear error messages for missing Specs
- Validate format option
- Handle file write errors

### NFR-3: Usability
- Intuitive command syntax
- Helpful error messages
