Slash Commands

Commands are user-invoked shortcuts that execute specific actions.

Built-in Commands

Command	Description	When to Use
`/help`	Show help information	Get started, learn commands
`/btw`	Ephemeral side question — doesn't pollute main context	Quick tangent questions
`/chrome`	Configure Chrome integration	Browser automation
`/clear`	Clear conversation history	Start fresh, reduce context
`/diff`	Interactive diff viewer. In the fullscreen TUI (v2.1.260+) it opens a diff panel beside the conversation that stays open and refreshes each time Claude edits a file or runs a command; the classic renderer opens the viewer in place of the prompt instead	Review changes
`/config`	View/edit configuration	Customize behavior
`/status`	Show session status	Check current state
`/agents`	Removed: the wizard went in v2.1.198 and the command left the `/` menu and `/help` in v2.1.281 — ask Claude to create or manage subagents, or edit `.claude/agents/`	Manage subagents by asking Claude
`/skills`	List available skills	See auto-invoke capabilities
`/hooks`	List configured hooks	Debug automation
`/insights`	Analyze session patterns	Session optimization
`/install-slack-app`	Install Claude Slack app	Slack integration
`/keybindings`	Customize keyboard shortcuts	Key customization
`/mcp`	List MCP servers	Check external integrations
`/memory`	View loaded memory files	Debug context loading
`/mobile`	Generate mobile QR code	Mobile access
`/passes`	View usage passes	Subscription info
`/plugin`	Manage plugins	Install/remove extensions
`/plan`	Enter planning mode	Complex implementations
`/proactive`	Alias for `/loop` (v2.1.105)	Same as `/loop`
`/recap`	Show session recap when returning to a session	After being away, get context on what was done
`/rewind`	Rewind to checkpoint	Undo changes, explore alternatives
`/checkpoint`	Manage checkpoints	Save/restore states
`/cost`	Shortcut alias that opens the cost tab of `/usage` (v2.1.118+)	Monitor spending
`/context`	Show context window usage	Manage conversation length
`/export`	Export conversation	Save for reference
`/usage-credits`	Configure extra usage limits (renamed from `/extra-usage` in v2.1.144; old name still works as alias)	Rate limit management
`/feedback`	Submit feedback or bug report	Report issues
`/login`	Authenticate with Anthropic	Access features
`/logout`	Sign out	Switch accounts
`/sandbox`	Toggle sandbox mode	Safe command execution
`/doctor`	Run diagnostics	Troubleshoot issues
`/reload-plugins`	Reload installed plugins. Since v2.1.221 most installs activate immediately; only needed when the install summary says `Run /reload-plugins to activate.` Available in headless sessions since v2.1.260+, so it appears in the Claude Code Desktop and SDK command lists	Plugin management
`/reload-skills`	Re-scan skill directories without restarting (v2.1.152)	Skill management
`/workflows`	View running and completed dynamic workflow runs (v2.1.154)	Multi-agent orchestration

`/teleport` (alias `/tp`)	Resume a Claude Code on the web session in this terminal; opens a picker. Requires a claude.ai subscription	Continue work remotely
`/desktop`	Open Claude Desktop app	Switch to desktop interface
`/theme`	Change color theme; v2.1.118 added custom named themes via `~/.claude/themes/<name>.json` (plugins can ship a `themes/` dir)	Customize appearance
`/usage`	Canonical command for usage/cost/stats — merged `/cost` and `/stats` into a single tabbed view (v2.1.118); as of v2.1.149 the cost view breaks spending down by category (skills, subagents, plugins, per-MCP-server). In the VSCode extension (v2.1.174), the `/usage` (Account & usage) dialog adds an attribution breakdown — cache misses, long-context cost, subagents, and per-skill / per-agent / per-plugin / per-MCP usage over 24h and 7d windows	Monitor quota and costs
`/focus`	Toggle focus view (distraction-free output display)	Reduce visual noise during long tasks
`/fork`	Copy the conversation into a new independent background session (v2.1.212+)	Explore alternatives in parallel

`/team-onboarding`	Generate a teammate ramp-up guide from this project's Claude Code usage	Onboarding new teammates (v2.1.101)
`/code-review ultra`	Run a cloud multi-agent code review over your current changes. `/ultrareview` remains as an alias; `/code-review ultra` is the preferred invocation. Includes 3 free runs on Pro and Max, then requires usage credits	Deep pre-merge review across multiple agents (v2.1.112)
`/fewer-permission-prompts`	Scan transcripts and propose a prioritized allowlist for common read-only tools	Reduce repeat permission prompts in a project (v2.1.112)
`/skill-doctor`	Show which loaded skills go unused and what they cost in context. Opens in the `/plugin` manager's Stats tab; prints as text under `-p`	Prune skills you no longer need (v2.1.252+)

Reference: Official Docs

Subagents

Specialized AI assistants with isolated contexts for specific tasks.

Nested spawning is on by default, depth 3 (v2.1.219): Subagents can spawn their own subagents up to three layers below the main conversation. Set CLAUDE_CODE_MAX_SUBAGENT_SPAWN_DEPTH to change the limit, or 1 to disable nesting. (History: v2.1.172–v2.1.216 nested by default up to 5 layers with no way to change it; v2.1.217 made nesting opt-in at depth 1; v2.1.219 set the default to 3.) See 04-subagents/README.md for the Agent(agent_type) syntax that restricts which subagents a given subagent may spawn.

`/batch`	Run prompts on multiple files	Batch operations
`/claude-api`	Build apps with Claude API	API development
`/debug`	Debug failing tests/errors	Debugging sessions
`/design` (research preview, v2.1.233+)	Create a multi-artboard design canvas — UI mockups, screen flows, landing pages, posters — refined visually instead of in code. Pro/Max/Team/Enterprise	Designing a screen or page you would rather tweak by hand than in HTML

`/code-review [low\|medium\|high\|xhigh\|max\|ultra] [--fix] [--comment] [pr#\|branch\|path]`	Review the current diff — or a PR, branch, or path — for correctness bugs. `--fix` applies findings, `--comment` posts them as inline PR comments. With no level given it reuses the last one you typed (v2.1.223). Lower effort levels moved to a background subagent in v2.1.218; `high`, `xhigh`, and `max` followed in v2.1.232, so review output no longer fills the conversation	After writing code, before landing a PR

Sandboxing	Isolated execution environments for safety	Use `/sandbox` to toggle; runs commands in restricted environments
MCP OAuth	OAuth authentication for MCP servers	Configure OAuth credentials in MCP server settings for secure access
MCP Tool Search	Search and discover MCP tools dynamically	Use tool search to find available MCP tools across connected servers
Scheduled Tasks	Set up recurring tasks with `/loop` and cron tools	Use `/loop 5m /command` or CronCreate tool
Chrome Integration	Browser automation with headless Chromium	Use `--chrome` flag or `/chrome` command
Keyboard Customization	Customize keybindings including chord support	Use `/keybindings` or edit `~/.claude/keybindings.json`
Auto Mode	Fully autonomous operation with background safety classifier checks	`Shift+Tab` to cycle to it, or `--permission-mode auto`
Channels	Multi-channel communication (Telegram, Slack, etc.) (Research Preview)	Configure channel plugins; March 2026
Voice Dictation	Voice input for prompts	Use microphone icon or voice keybinding
Agent Hook Type	Hooks that spawn a subagent instead of running a shell command	Set `"type": "agent"` in hook configuration
Prompt Hook Type	Hooks that inject prompt text into the conversation	Set `"type": "prompt"` in hook configuration
MCP Elicitation	MCP servers can request user input during tool execution	Handle via `Elicitation` and `ElicitationResult` hook events
Plugin LSP Support	Language Server Protocol integration via plugins	Configure LSP servers in `plugin.json` for editor features
Managed Drop-ins	Organization-managed drop-in configurations (v2.1.83)	Admin-configured via managed policies; auto-applied to all users
`claude plugin init`	Scaffold a new plugin in `.claude/skills`; such plugins auto-load with no marketplace (v2.1.157)	Run `claude plugin init <name>`
Auto Mode on third-party providers	Available by default on Amazon Bedrock, Google Cloud's Agent Platform, Microsoft Foundry, and signed-in Claude apps gateway sessions, where the supported models are Claude Sonnet 5 or later, Opus 4.7 or later, Haiku 5.5 (v2.1.293+), and the Fable models (opt-in required v2.1.158–v2.1.206; removed in v2.1.207 — `CLAUDE_CODE_ENABLE_AUTO_MODE` is still accepted but has no effect)	`Shift+Tab` to cycle to it, or `--permission-mode auto`
Immediate Dialog Commands	`/permissions` can be opened while Claude is working (rule changes apply to the rest of the turn), and the `/add-dir`, `/autocompact`, `/theme`, `/help`, `/config`, and `/advisor` dialogs open mid-turn in the fullscreen TUI instead of queuing until Claude finishes responding (`/bug` already did this since v2.1.232) (v2.1.234)	Run one of these commands while Claude is working. See Slash Commands
`CLAUDE_CODE_PROJECT_DIR_NAME`	Env var controlling per-project transcript directory naming (v2.1.234)	Set in your shell/env before launching Claude Code. See CLI
Goal Check-In Threshold	While a `/goal` is active, Claude checks in with a status update if a background task makes no progress for 30+ minutes, instead of continuing silently; tune with `CLAUDE_CODE_GOAL_CHECKIN_MINUTES`, or set to `0` to disable (v2.1.234)	Set `CLAUDE_CODE_GOAL_CHECKIN_MINUTES=<n>` alongside an active `/goal`. See Slash Commands
Usage-Limit Auto-Continue	Claude Code auto-continues a session when a claude.ai usage limit resets, if it was blocked on that limit (v2.1.234)	On by default; turn it off in `/config` → "Continue automatically at usage limit". See Advanced Features
`spellcheck` setting	Underlines misspelled words in the prompt input using whichever of aspell, hunspell, or ispell is on your `PATH`; off by default (v2.1.235)	Install a checker, then set `"spellcheck": { "enabled": true }` in `~/.claude/settings.json`. User, `--settings`, and managed settings only — ignored in project settings. See Advanced Features
Agent Teams Default Model	The "Default teammate model" `/config` setting was removed; teammates now inherit the team lead's model by default unless the spawn call specifies one explicitly (v2.1.234)	See Subagents — Agent Teams
`/design`	Design canvas — a multi-artboard visual design (UI mockups, screen flows, landing pages, posters) built on artifacts and refined visually rather than in code. Research preview; requires v2.1.233+; Pro/Max/Team/Enterprise	Run `/design` in the CLI or the Desktop app. See Slash Commands
`notify_when_idle`	Cross-session `SendMessage` input that asks another session on the same machine to send one notice when it next goes idle — opt-in, one-shot, no polling (v2.1.236). Related: `ListAgents` reports the session's own name and lists live teammates, and Windows gained cross-session messaging (v2.1.239)	Pass `notify_when_idle` to `SendMessage`. See Advanced Features
Plugin manifest fields	`plugin.json` accepts `workflows`, `channels`, `dependencies` (semver), `outputStyles`, `keywords`, `metadata`, `lspServers`, and `experimental.themes` / `experimental.monitors`. CLI gained `claude plugin new`, `remove`/`rm`, `prune`/`autoremove`, and the flags `--with`, `-f`/`--force`, `--available`, `--push`, `--dry-run`	See Plugins
Restricted Mode	Removes the built-in tools that run commands or code (Bash, PowerShell, REPL) and WebFetch unless `--tools` names them; ignores user, project, and local settings (managed settings and `--settings` still apply); confines file tools to the working directories; refuses `bypassPermissions`; and refuses to create cloud sessions (v2.1.248+)	`claude --restricted`, or `CLAUDE_CODE_RESTRICTED=1`. See CLI
`/advisor` text form	`/advisor`, `/advisor <model>`, and `/advisor off` work as text commands in the desktop app, Remote Control, and other headless (`-p` / Agent SDK) sessions, not just as a dialog (v2.1.260+)	Type `/advisor off` in a headless session. See Slash Commands
