Claude Code Slash Commands: Complete Reference Guide

By Learnia Team

Claude Code Slash Commands: Complete Reference Guide

This article is written in English. Our training modules are available in French.

Slash commands are the fastest way to control Claude Code. Instead of typing out full instructions, use a single command to trigger complex operations. This reference covers every built-in command, from essential daily tools to advanced configuration options.

How Slash Commands Work

Slash commands start with 

/
and execute immediately. Type them anywhere in your prompt:

> /review
> Can you /compact the conversation and then continue?

Command Anatomy

/command [arguments]
  • →command: The action to perform
  • →arguments: Optional parameters (some commands require them)

Getting Help

> /help

Lists all available commands with descriptions.

Essential Commands

These are the commands you'll use daily:

/init — Initialize Project

Creates a 

CLAUDE.md
file for your project.

> /init

Claude Code scans your project and generates a tailored memory file with:

  • →Project overview
  • →Tech stack detection
  • →Suggested conventions
  • →Directory structure

Best practice: Run this first in any new project.

/review — Code Review

Requests a code review of recent changes.

> /review

Claude analyzes:

  • →Uncommitted changes (
    git diff
    )
  • →Code quality issues
  • →Potential bugs
  • →Style inconsistencies

With specific focus:

> /review focus on security vulnerabilities
> /review check the API error handling

/compact — Compress Conversation

Compacts conversation history to free up context.

> /compact

When your conversation gets long, Claude's context window fills up. Compacting:

  • →Summarizes older messages
  • →Preserves important context
  • →Frees tokens for new work

With focus instructions:

> /compact focus on the authentication work

Claude keeps authentication-related context while compressing other parts.

/cost — Token Usage

Shows token usage for the current session.

> /cost

Output:

Session Usage:
- Input tokens:  45,230
- Output tokens: 12,450
- Total cost:    $0.47

Context window: 67% used

/clear — Clear Conversation

Clears conversation history and starts fresh.

> /clear

Warning: This cannot be undone. Use 

/compact
instead if you want to preserve some context.

/exit — Exit Claude Code

Exits the interactive session.

> /exit

Or use 

Ctrl+C
twice.
