Session & Memory
/init
Initialize project with
CLAUDE.md. Creates your project's persistent instruction file read at every session start./memory
View and manage auto-memory files. Use
# prefix in the REPL to add things to memory without editing files./resume
Resume a previous session.
/resume 1 for most recent, /resume name by name. Sessions are resumable up to 7 days./rename
Name the current session for easy resuming. Example:
/rename pr-review/clear
Clear conversation history. Keeps files and memory intact — only the chat context is wiped.
/compact
Condense conversation history to free up context. Optionally focus:
/compact focus on tests/context
View context window usage with actionable suggestions on when to compact.
/export
Export the conversation transcript to a file.
/rewind
Return to a prior checkpoint. Also triggered by pressing Esc Esc.
/branch
Branch the conversation for parallel exploration without affecting your main session.
Model & Effort
/model
Switch model mid-session. Options:
/model sonnet (default, Sonnet 5), /model opus (Opus 4.8), /model haiku, /model fable. Also Alt+P while typing./effort
Set reasoning effort:
low, medium, high, xhigh. Use /effort xhigh with Opus for hardest agentic work./fast
Toggle fast output mode for quicker, lighter responses.
/usage
View token usage, cost, and plan limits.
/cost and /stats are shortcuts that open specific tabs here./status
View current session state: active model, permission mode, and settings summary.
Autonomous Work
/loop agentic
Run a prompt or command on a repeating interval.
/loop 3h check PRs, /loop 5m /my-skill, or bare /loop for self-paced maintenance. Stop with /loop stop or Ctrl+C./goal v2.1.139+
Set a completion condition; Claude keeps going autonomously until the condition is met. Example:
/goal all tests pass. Uses a fast model to evaluate after each turn./plan
Enter plan mode — Claude outlines the approach before touching any files. Best before large refactors.
/plan fix the auth module/batch
Run batch operations across multiple files or targets in parallel.
/tasks
List all background agents currently running in this session.
/bashes
List background bash tasks spawned by Claude.
Tip:
/loop vs /goal — use /loop when you want Claude to wake up on a schedule. Use /goal when you want Claude to keep working until a condition is true.
Code Quality
/code-review
Find correctness bugs. Supports effort levels:
/code-review medium, /code-review ultra. Use --fix to auto-apply fixes, --comment to post inline GitHub PR comments./security-review
Review code specifically for security vulnerabilities — OWASP Top 10, secrets, injection risks.
/claude-api
Get help building apps with the Anthropic SDK — tool use, batch processing, MCP integration, streaming.
Parallel & Agents
/agents
Open Agent View — an operations screen for running, blocked, and completed Claude Code sessions. Up to 10 subagents can run in parallel.
/skills
List installed skills with a type-to-filter search box. Skills are prompt-based commands stored in
.claude/skills/./add-dir
Expand file access by adding additional working directories to the session.
Config & Permissions
/config
Open the full settings interface interactively.
/permissions
Manage permission settings interactively — what Claude can read, edit, and execute.
/hooks
View current hook configuration. Hooks fire on events like
PreToolUse, PostToolUse, Stop, etc./mcp
Configure MCP servers.
/mcp enable, /mcp disable. MCP expands Claude's tool access to external services./doctor
Full setup checkup — diagnoses and fixes environment issues. Alias:
/checkup/bug
Report a bug directly to Anthropic from within your session.
/login / /logout
Authenticate or sign out mid-session without restarting Claude Code.
