21 ? Okay, I understand. The archive folder will be ignored for the remainder of this session. I'm ready for your first
22 command.

24 > create a hello world Rust program in crate rustHello
25
26 ? Okay, I will create a "hello world" Rust program in the RustHello crate. I will first check the existing src/main.rs
27 file. If it doesn't contain the standard "Hello, world!" program, I will update it. Finally, I will compile and run
28 the program to ensure it works correctly.

| Command | Description |
|---|---|
| /add-dir | Add additional working directories to Claude's context. Useful when working across multiple repositories or accessing files outside the current project. |
| /agents | Manage custom AI subagents for specialized tasks. Create, list, and configure subagents that Claude can delegate work to (e.g., a code-reviewer or debugger agent). |
| /bashes | List and manage background bash tasks. Shows running background commands started with Ctrl+B, letting you check status and retrieve output. |
| /bug | Report a bug to Anthropic. Sends the current conversation context to help diagnose and fix Claude Code issues. |
| /clear | Clear conversation history and start fresh. Wipes all context from the current session. Unlike /compact, gives Claude a completely clean slate (though CLAUDE.md and project files remain accessible). |
| /compact [instructions] | Compress conversation context by summarizing older messages while preserving important details. Optional focus instructions keep specific topics intact (e.g., /compact focus on authentication logic). Triggers automatically when context is nearly full. |
| /config | Open the Settings interface (Config tab). Menu-driven way to change settings like vim mode, theme, model preferences, verbose output, and more. |
| /context | Visualize current context window usage as a colored grid. Acts as a fuel gauge showing what's consuming context: files, conversation history, system prompts, and skill descriptions. Helps decide when to /compact or /clear. |
| /cost | Show token usage statistics for the current session, including input/output tokens, total cost, and context window utilization. Behavior varies by subscription plan. |
| /doctor | Run a health check on your Claude Code installation. Verifies connectivity, authentication, Node.js version, npm packages, and other prerequisites. Run this first when troubleshooting. |

| /hooks | Open interactive menu to manage hook configurations. Hooks are shell commands that run at lifecycle events: PreToolUse, PostToolUse, Notification, and Stop. |
| /ide | Manage IDE integrations and show their status. Claude Code can connect to VS Code, JetBrains, and other editors for jump-to-file and inline editing. |
| /init | Initialize your project by creating a CLAUDE.md file. This is the single most important file for Claude Code — it gives Claude persistent context about your project: build commands, conventions, architecture, and key files. |
| /install-github-app | Install the Claude GitHub App for a repository. Once installed, Claude automatically reviews pull requests, catching logic errors and security issues. Generates a claude-code-review.yml for customizing review behavior. |
| /login | Switch to a different Anthropic account. Useful when you have separate personal and work accounts. |
| /logout | Sign out from your current Anthropic account. |
| /mcp | Manage Model Context Protocol server connections. View configured servers, check connection status, authenticate with OAuth-enabled servers, and see available tools/prompts. |

| /model | Switch the active AI model. Accepts aliases (sonnet, opus, haiku) or full model strings. Example: /model opus. |
| /output-style [style] | Set the output style for Claude's responses. Specify a style directly or choose from a selection menu. Controls formatting, verbosity, and response structure. |
| /permissions | View or update tool permission settings. Controls which tools Claude can use freely, which require approval, and which are denied. Supports exact matches and prefix wildcards. |

| /resume | Resume a previous conversation by ID or name. Without arguments, opens an interactive session picker with preview (P), rename (R), and delete shortcuts. |
| /review | Request a code review of recent changes. Claude examines modified files and provides feedback on quality, bugs, security, and improvements. |
| /rewind | Open the rewind menu (also via Esc+Esc). Scrollable list of your prompts. Restore code and/or conversation to a prior checkpoint, or summarize from a given point to free context. |
| /sandbox | Enable sandboxed bash execution with filesystem and network isolation. Safer, more autonomous execution by constraining what commands can access. |
| /security-review | Run a comprehensive security review of all pending changes on the current git branch. Focused on vulnerability detection, exposed credentials, and insecure configurations. |
