Usage: claude [options] [command] [prompt]
Claude Code - starts an interactive session by default, use -p/--print for non-interactive output
Arguments:
prompt Your prompt
Options:
--add-dir <directories...> Additional directories to allow tool access to
--agent <agent> Agent for the current session. Overrides the 'agent' setting.
--agents <json> JSON object defining custom agents (e.g. '{"reviewer": {"description": "Reviews code", "prompt": "You are a code reviewer"}}')
--allow-dangerously-skip-permissions Enable bypassing all permission checks as an option, without it being enabled by default. Recommended only for sandboxes with no internet access.
--allowedTools, --allowed-tools <tools...> Comma or space-separated list of tool names to allow (e.g. "Bash(git:*) Edit")
--append-system-prompt <prompt> Append a system prompt to the default system prompt
--bare Minimal mode: skip hooks, LSP, plugin sync, attribution, auto-memory, background prefetches, keychain reads, and CLAUDE.md auto-discovery. Sets
CLAUDE_CODE_SIMPLE=1. Anthropic auth is strictly ANTHROPIC_API_KEY or apiKeyHelper via --settings (OAuth and keychain are never read). 3P providers
(Bedrock/Vertex/Foundry) use their own credentials. Skills still resolve via /skill-name. Explicitly provide context via: --system-prompt[-file],
--append-system-prompt[-file], --add-dir (CLAUDE.md dirs), --mcp-config, --settings, --agents, --plugin-dir.
--betas <betas...> Beta headers to include in API requests (API key users only)
--brief Enable SendUserMessage tool for agent-to-user communication
--chrome Enable Claude in Chrome integration
-c, --continue Continue the most recent conversation in the current directory
--dangerously-skip-permissions Bypass all permission checks. Recommended only for sandboxes with no internet access.
-d, --debug [filter] Enable debug mode with optional category filtering (e.g., "api,hooks" or "!1p,!file")
--debug-file <path> Write debug logs to a specific file path (implicitly enables debug mode)
--disable-slash-commands Disable all skills
--disallowedTools, --disallowed-tools <tools...> Comma or space-separated list of tool names to deny (e.g. "Bash(git:*) Edit")
--effort <level> Effort level for the current session (low, medium, high, max)
--fallback-model <model> Enable automatic fallback to specified model when default model is overloaded (only works with --print)
--file <specs...> File resources to download at startup. Format: file_id:relative_path (e.g., --file file_abc:doc.txt file_def:img.png)
--fork-session When resuming, create a new session ID instead of reusing the original (use with --resume or --continue)
--from-pr [value] Resume a session linked to a PR by PR number/URL, or open interactive picker with optional search term

"stream-json")
--permission-mode <mode> Permission mode to use for the session (choices: "acceptEdits", "bypassPermissions", "default", "dontAsk", "plan", "auto")
--plugin-dir <path> Load plugins from a directory for this session only (repeatable: --plugin-dir A --plugin-dir B) (default: [])
-p, --print Print response and exit (useful for pipes). Note: The workspace trust dialog is skipped when Claude is run with the -p mode. Only use this flag in directories

mcp Configure and manage MCP servers
plugin|plugins Manage Claude Code plugins
