Deep Agents CLI

Terminal coding agent with persistent memory, skills, sandboxed execution, and 20+ LLM providers. Built on LangGraph. See the official overview and CLI guide.

Quick Start

# Interactive session (default agent, default model)
deepagents

# Interactive with specific agent and model
deepagents -a myagent -M anthropic:claude-sonnet-4-5

# Non-interactive one-shot task
deepagents -n "Summarize README.md"

# Non-interactive with shell access
deepagents -n "List Python files and count lines" --shell-allow-list ls,wc,find

# Resume last session
deepagents -r

Core Concepts

Agents = Isolated Personas

Each agent has its own memory, skills, and AGENTS.md context file (default agent shown; use -a <name> for named agents):

~/.deepagents/default/
├── AGENTS.md          # Always-loaded context (preferences, conventions)
├── memories/          # Auto-saved topic memories
└── skills/            # User-level skills

deepagents -a researcher      # Use "researcher" agent
deepagents -a coder           # Use "coder" agent
deepagents list               # List all agents
deepagents reset --agent NAME # Clear agent memory

Memory vs Skills

See Memory & Persistence and Skills System for details on each system.

Two Operating Modes

Interactive Mode

Launch the REPL with deepagents. Key controls (see CLI Reference for the complete list):

Slash Commands

/model               # Interactive model selector
/model provider:name # Switch to specific model
/remember [context]  # Update memory and skills from conversation
/tokens              # Show token usage
/clear               # Clear conversation history and start new thread
/threads             # Browse and resume previous threads
/trace               # Open current thread in LangSmith
/changelog           # Open CLI changelog in browser
/docs                # Open documentation in browser
/feedback            # File bug report or feature request
/version             # Show version
/quit                # Exit CLI (alias: /q)
/help                # Show all commands

Non-Interactive Mode

For automation and scripting — runs a single task and exits (see Workflows & Patterns for CI/CD recipes):

# Basic task
deepagents -n "Analyze this codebase for security issues"

# With shell access (default: no shell in non-interactive)
deepagents -n "Run tests and report failures" --shell-allow-list recommended
deepagents -n "Search logs for errors" --shell-allow-list ls,cat,grep

# Auto-approve all tool calls
deepagents --auto-approve -n "Generate docs for all modules"

# Specific model
deepagents -M ollama:qwen3:8b -n "Explain this code"

Shell access in non-interactive mode is disabled by default. Use --shell-allow-list:

• recommended — safe defaults
• ls,cat,grep,... — explicit comma-separated list

Piping and stdin

The CLI accepts piped input via stdin. When input is piped, the CLI automatically runs non-interactively:

# Pipe content for analysis
echo "Explain this code" | deepagents
cat error.log | deepagents -n "What's causing this error?"
git diff | deepagents -n "Review these changes"

# Clean output for piping to other commands
deepagents -n "Generate a .gitignore for Python" -q > .gitignore
deepagents -n "List dependencies" -q --no-stream | sort

When piped input is combined with -n or -m, the piped content is prepended to the flag's value. The maximum piped input size is 10 MiB.

Model Selection

See Providers & Models for all 20+ supported providers, API key setup, and config.toml format. See also the official providers guide.

At Launch

deepagents -M anthropic:claude-sonnet-4-5
deepagents -M openai:gpt-4o
deepagents -M ollama:qwen3:8b

During Session

/model                          # Interactive picker
/model anthropic:claude-opus-4-6  # Direct switch

Default Model

deepagents --default-model anthropic:claude-sonnet-4-5  # Set default
deepagents --default-model                               # Show current
deepagents --clear-default-model                         # Clear default

Resolution Order

1. -M flag (always wins)
2. [models].default in ~/.deepagents/config.toml
3. [models].recent (last /model switch, auto-saved)
4. First available API key: OPENAI_API_KEY → ANTHROPIC_API_KEY → GOOGLE_API_KEY → GOOGLE_CLOUD_PROJECT

Skills Management

See Skills System for the full SKILL.md format and progressive disclosure. See also the official skills docs.

deepagents skills create my-skill             # Create user skill
deepagents skills create my-skill --project   # Create project skill
deepagents skills list                        # List user skills
deepagents skills list --project              # List project skills
deepagents skills info my-skill               # Show skill details
deepagents skills delete my-skill             # Delete user skill
deepagents skills delete my-skill --project   # Delete project skill

User skills: ~/.deepagents/<agent>/skills/ Project skills: <project>/.deepagents/skills/ (requires .git in project root)

Project skills override user skills with the same name.

Sandbox Execution

Run agent code in isolated environments (see Sandboxes for setup guides and official sandbox docs):

deepagents --sandbox modal --sandbox-setup ./setup.sh
deepagents --sandbox runloop
deepagents --sandbox daytona
deepagents --sandbox langsmith
deepagents --sandbox-id EXISTING_ID    # Reuse sandbox

Sandbox providers: Modal (ML/GPU), Runloop (disposable devboxes), Daytona (fast cold starts), LangSmith (cloud deployment).

Built-in Tools

Use --auto-approve or Shift+Tab in REPL to bypass approval prompts.

Common Workflows

Code Analysis (Safe, Read-Only)

deepagents -n "Analyze src/ for code quality issues"

Code Generation with File Writing

deepagents --auto-approve -n "Generate unit tests for src/auth.py"

Research with Memory Persistence

deepagents -a researcher -m "Research best practices for Python async"
# Agent saves findings to memories/ automatically
# Next session:
deepagents -a researcher -m "What did we learn about async?"

Project-Scoped Agent

cd my-project
# Create .deepagents/AGENTS.md with project conventions
mkdir -p .deepagents
echo "# Project uses FastAPI, PostgreSQL, pytest" > .deepagents/AGENTS.md
deepagents -m "Help me add a new API endpoint"

Configuration

Global config: ~/.deepagents/config.toml (see Providers & Models for the full config.toml schema)

[models]
default = "anthropic:claude-sonnet-4-5"

[models.providers.ollama]
base_url = "http://localhost:11434"
models = ["qwen3:8b", "llama3"]

[models.providers.ollama.params]
temperature = 0
num_ctx = 8192

Tips

• `@filename` in REPL auto-completes and injects file contents into your prompt
• `!command` runs shell commands directly without agent interpretation
• `/remember [context]` explicitly triggers memory/skill updates — pass optional context to guide the update
• `-n` mode has no shell by default — add --shell-allow-list recommended for safe commands
• Local models (Ollama) work for simple tasks but may struggle with complex tool-calling — use Anthropic/OpenAI for multi-step work
• Reset an agent with deepagents reset --agent NAME if memories accumulate irrelevant info
