name: meta-command description: Guide for creating and validating Claude Code slash commands. Use when users want to create a command, define command specs, configure allowed-tools or argument-hint fields, or validate and audit existing commands. Do NOT use for creating skills or agents (use meta-skill, meta-agent).

Meta-Command

A meta-skill for creating and validating Claude Code slash commands. Supports Claude Code and OpenCode platforms.

Output Language: All generated command content will be in English.

Workflow Routing

Intent	Reference
Create a new command (full process)	workflows/create-command.md
Validate existing command(s)	workflows/validate-command.md
Official field specification	references/official-spec.md
Best practices & patterns	references/best-practices.md
Real-world examples	references/examples.md

Quick Start

Create a New Command

1. Determine command category (see below)
2. Create file: .claude/commands/{name}.md
3. Add frontmatter + content
4. Test with /command-name

Validate Commands

See workflows/validate-command.md for the full validation workflow.

Command Categories

Choose the appropriate category based on purpose:

Category	Purpose	Tools	Examples
orchestrator	Multi-phase pipeline	Read, Write, Glob	/organize-, /create-
action	Execute specific task	Bash(cmd:*), Write	/deploy, /build
query	Gather information	Read, Grep, Glob	/search, /analyze
generator	Create files/content	Write, Read	/init-*, /scaffold
interactive	User input workflow	Question, Read, Write	/setup, /configure

Command Creation Workflow (5 Phases)

Phase	Goal	Key Output
1. DEFINE	Clarify purpose	Name + description
2. CLASSIFY	Select category	Category + tools
3. DESIGN	Write structure	Frontmatter + body
4. INTEGRATE	Add skill references	@skill links
5. TEST	Validate	Working command

Phase 1: DEFINE

Questions to answer:

• What does this command do?
• Who triggers it? (always human)
• What inputs does it need?
• What outputs does it produce?

Phase 2: CLASSIFY

Select category and determine:

• allowed-tools based on category
• model if specific reasoning needed
• disable-model-invocation for destructive commands

Phase 3: DESIGN

Write the command file:

---
description: Brief purpose (shown in command list)
allowed-tools: Tool1, Tool2, Bash(cmd:*)
argument-hint: [required] [--optional]
---

# Command Title

## Arguments
$ARGUMENTS
- **required**: Description
- **--optional**: Description

## Instructions
[Step-by-step procedure]

## Output
### Success
[Format]
### Failure
[Format]

## Safety
| Check | Action |
|-------|--------|
| Risk | Mitigation |

Phase 4: INTEGRATE

Add skill references for domain knowledge:

## Instructions

1. Read @.claude/skills/meta-command/SKILL.md
2. Apply validation rules from skill

Key Principle: Command orchestrates the pipeline; Skills provide domain knowledge. Skills can also invoke other skills via the Skill tool when composition is intentional.

Phase 5: TEST

• Run command with valid arguments
• Run with missing/invalid arguments
• Verify tool restrictions work
• Check output format

Frontmatter Fields

Field	Required	Type	Description
description	Yes	string	Brief description shown in command list
allowed-tools	No	string/array	Tool restrictions
argument-hint	No	string	Placeholder: [arg1] [--flag]
model	No	string	haiku, sonnet, opus
disable-model-invocation	No	boolean	Prevent programmatic invocation

Tool Scoping Patterns

Need	Pattern
Git operations	Bash(git:*)
npm scripts	Bash(npm:*)
Docker	Bash(docker:*)
All bash (not recommended)	Bash

Dynamic Content Syntax

Syntax	Purpose	Example
$ARGUMENTS	All arguments as string	Review $ARGUMENTS
$1, $2, ...	Positional arguments	Deploy $1 to $2
@path/to/file	File reference	@.claude/skills/skill/SKILL.md
!`command`	Embedded bash	!`git status`

Command Structure Template

allowed-tools: Tool1, Tool2, Bash(cmd:*)

Relationship Patterns

Command + Skill

⚡ COMMAND: Orchestrates flow
    ↓
📚 SKILL: Provides knowledge (read-only)
    ↓
🔧 TOOL: Executes operations

Command + Agent

For complex reasoning, commands can delegate:

## Instructions

For complex analysis, consult oracle agent:
1. Gather context
2. Delegate reasoning to oracle
3. Apply recommendations

Anti-Patterns to Avoid

Anti-Pattern	Problem	Solution
Missing description	Not discoverable	Add meaningful description
allowed-tools: Bash	Too permissive	Use Bash(cmd:*) pattern
Hardcoded domain knowledge	Not reusable	Extract to skill
Missing output examples	Unclear expectations	Add Output section
No safety section	Risk of damage	Add Safety for side effects
Excessive skill coupling	Review needed	If 3+ skills invoked, consider Command/Agent

Validation Checklist

Frontmatter

• description present and meaningful
• allowed-tools properly scoped
• argument-hint if command takes args
• disable-model-invocation: true for destructive

Structure

• ## Arguments if argument-hint present
• ## Instructions with clear steps
• ## Output with examples
• ## Safety for side effects

Integration

• Skills use @.claude/skills/... syntax
• Referenced skills exist
• Pipeline ownership respected
