name: claude-code-commands description: Create slash commands for Claude Code with $ARGUMENTS handling, agent invocation patterns, and template best practices. Reference for building user-triggered workflow shortcuts.

Claude Code Commands — Meta Reference

This skill provides the definitive reference for creating Claude Code slash commands. Use this when building new commands or improving existing command patterns.

---

When to Use This Skill

Use this skill when you need to:

• Create a new slash command for repeated workflows
• Add $ARGUMENTS handling to commands
• Invoke agents from commands
• Include file context or bash output in commands
• Organize commands for team sharing

---

Quick Reference

Command Locations

Nested discovery: Claude automatically discovers .claude/commands/ in subdirectories when editing files in those paths (useful for monorepos).

Command Structure

Copy.claude/commands/

├── test.md             # /test
├── security-scan.md    # /security-scan
└── deploy.md           # /deploy

$ARGUMENTS Usage

Single Argument

Copy# Code Review

Review the following file or code for quality, security, and best practices:

$ARGUMENTS

Focus on:
- Code quality issues
- Security vulnerabilities
- Performance concerns
- Best practice violations

Usage: /review src/auth.js

Multiple Arguments

Copy# Compare Files

Compare these two files and explain the differences:

$ARGUMENTS

Provide:
- Line-by-line diff
- Semantic changes
- Impact analysis

Usage: /compare old.js new.js

Optional Arguments

Copy# Run Tests

Run tests for the specified scope.

Scope: $ARGUMENTS

If no scope specified, run all tests.
If scope is a file, run tests for that file.
If scope is a directory, run tests in that directory.

Usage: /test or /test auth/ or /test login.test.ts

Positional Arguments

Use $1, $2, etc. for specific arguments (like shell scripts):

Copy# Compare Files

Compare $1 with $2.

Show:
- Line differences
- Semantic changes
- Which version is preferred

Usage: /compare old.js new.js → $1 = "old.js", $2 = "new.js"

---

File References (@ Prefix)

Include file contents directly in the command with @:

Copy# Review with Context

Review this code following our standards.

Project standards:
@CLAUDE.md

Code to review:
$ARGUMENTS

Usage: /review-context src/auth.js includes CLAUDE.md contents automatically.

---

Bash Execution (! Prefix)

Execute bash commands and include output with !:

Copy# Smart Commit

Current status:
!git status --short

Recent commits:
!git log --oneline -5

Staged changes:
!git diff --cached

Generate a commit message for the staged changes.

Usage: /smart-commit runs git commands and includes their output.

Important: The !command syntax is preprocessing — commands execute BEFORE the content is sent to Claude. Claude only sees the final rendered output with actual data, not the command itself.

Backtick Syntax

For inline execution, use backticks:

CopyPR diff: !`gh pr diff`
Changed files: !`gh pr diff --name-only`

---

Command Patterns

Agent Invocation

Copy# Security Audit

Perform a comprehensive security audit.

Target: $ARGUMENTS

Use the **security-auditor** agent to:
1. Scan for OWASP Top 10 vulnerabilities
2. Check authentication patterns
3. Review data validation
4. Analyze dependencies

Provide a severity-rated findings report.

Multi-Agent Orchestration

Copy# Fullstack Feature

Build a complete fullstack feature.

Feature: $ARGUMENTS

Workflow:
1. Use **prd-architect** to clarify requirements
2. Use **system-architect** to design approach
3. Use **backend-engineer** for API implementation
4. Use **frontend-engineer** for UI implementation
5. Use **test-architect** for test coverage

Coordinate between agents and ensure integration.

Validation Command

Copy# Pre-Commit Check

Validate changes before commit.

Files: $ARGUMENTS (or all staged files if not specified)

Checklist:
- [ ] All tests pass
- [ ] No linting errors
- [ ] No type errors
- [ ] No console.log statements
- [ ] No TODO comments
- [ ] No hardcoded secrets

Return READY or BLOCKED with details.

Command Categories

Development Commands

Architecture Commands

Security Commands

Operations Commands

---

Naming Conventions

---

Command vs Agent vs Skill

Flow: User → Command → Agent → Skill

---

Invocation Control

Control who can invoke commands using frontmatter:

Example: User-Only Command

Copy---
description: Deploy to production
disable-model-invocation: true
allowed-tools: Bash(kubectl:*), Bash(docker:*)
---

# Deploy

Deploy $ARGUMENTS to production cluster.

Claude cannot auto-invoke this — user must explicitly type /deploy.

---

Context Budget

Default skill/command description budget: 15,000 characters.

If many commands are excluded from context:

Copyexport SLASH_COMMAND_TOOL_CHAR_BUDGET=20000

Check with /context command for warnings about excluded skills.

---

Best Practices

DO

Copy# Good Command

Clear, specific instructions.

Target: $ARGUMENTS

1. First, analyze the target
2. Then, perform action X
3. Finally, output result Y

Expected output:
- Summary of findings
- Actionable recommendations

DON'T

Copy# Bad Command

Do stuff with $ARGUMENTS.

Make it good.

---

Advanced Patterns

Conditional Logic

Copy# Smart Review

Review target: $ARGUMENTS

If target is a PR number (e.g., #123):
  - Fetch PR details with `gh pr view`
  - Review all changed files

If target is a file path:
  - Review that specific file

If target is a directory:
  - Review all files in directory

Template with Options

Copy# Generate Tests

Generate tests for: $ARGUMENTS

Options (parsed from arguments):
- `--unit` - Unit tests only
- `--e2e` - E2E tests only
- `--coverage` - Include coverage report

Default: Generate both unit and E2E tests.
