Command Creator

Overview

Creates slash commands for Claude Code plugins. Commands are user-invoked prompts that expand into detailed instructions for Claude.

When to use: User wants to create a command, add command to plugin, or needs command structure help.

References: See plugins/meta/claude-docs/skills/claude-docs/reference/plugins-reference.md for command specifications.

Command Structure Requirements

Every command MUST:

1. Be a .md file in commands/ directory
2. Include frontmatter with description
3. Contain clear instructions for Claude
4. Use descriptive kebab-case filename
5. Instructions written from Claude's perspective

Creation Process

Step 1: Define Command Purpose

Ask the user:

• What should this command do?
• What inputs/context does it need?
• What should Claude produce?

Step 2: Choose Command Name

Create concise kebab-case name:

• "generate tests" → generate-tests.md
• "review pr" → review-pr.md
• "deploy app" → deploy-app.md

Name becomes the command: /generate-tests

Step 3: Write Frontmatter

Required frontmatter:

---
description: Brief description of what command does
---

Step 4: Write Instructions

Write clear instructions for Claude:

# Command Title

Detailed instructions telling Claude exactly what to do when this command is invoked.

## Steps

1. First action Claude should take
2. Second action
3. Final action

## Output Format

Describe how Claude should present results.

## Examples

Show example scenarios if helpful.

Step 5: Verify Against Official Docs

Check plugins/meta/claude-docs/skills/claude-docs/reference/plugins-reference.md for command specifications.

Key Principles

• Clarity: Instructions must be unambiguous
• Completeness: Include all steps Claude needs
• Perspective: Write as if instructing Claude directly
• Frontmatter: Always include description
