description	Tambo CLI reference for project setup and component installation. Agent-friendly with non-interactive mode and exit codes. Use when running tambo init, tambo add, npx tambo commands, or browsing the component library. For guided project creation with tech recommendations, use start-from-scratch skill. For adding Tambo to existing projects, use add-to-existing-project skill.

Tambo CLI

Agent-friendly CLI for project setup and component management.

Quick Start

npx tambo init --api-key=sk_...              # Initialize with API key
npx tambo add message-thread-full --yes      # Add a component
npx tambo create-app my-app --template=standard  # New app from template

Non-Interactive Mode

The CLI detects non-interactive environments and returns guidance instead of hanging:

# In CI or piped environments, this returns guidance (exit 2) instead of prompting
npx tambo init
# Error: Project name required.
# Run one of:
#   tambo init --project-name=myapp    # Create new project
#   tambo init --project-id=abc123     # Use existing project

Detection Logic

Non-interactive when ANY of these are true:

• process.stdin.isTTY is false (piped input)
• process.stdout.isTTY is false (piped output)
• CI environment variable is set
• GITHUB_ACTIONS=true

Override with FORCE_INTERACTIVE=1 (requires real TTY).

Exit Codes

Code	Meaning
0	Success
1	Error (network, invalid args, etc.)
2	User action required - check stderr for exact command

Commands for Agents

Initialize Project

# Option 1: Direct API key (simplest for agents)
npx tambo init --api-key=sk_...

# Option 2: Create new project (requires prior auth)
npx tambo init --project-name=myapp

# Option 3: Use existing project
npx tambo init --project-id=abc123

# Skip all prompts with defaults
npx tambo init --yes --project-name=myapp

Add Components

npx tambo add form --yes                    # Skip confirmation
npx tambo add form graph --yes              # Multiple components
npx tambo add form --prefix=src/components  # Custom directory
npx tambo add form --dry-run                # Preview changes
npx tambo add form --legacy-peer-deps       # For dependency conflicts
