enhance

The enhance command adds agent-starter-pack capabilities to existing projects without creating a new directory. It's designed for upgrading prototypes to production-ready agents in-place.

Usage

uvx agent-starter-pack enhance [TEMPLATE_PATH] [OPTIONS]

Arguments

• TEMPLATE_PATH (optional): Can be:
  • . (default) - Use current directory as template
  • Local directory path - Use another local directory as template
  • Agent name - Use a built-in agent (e.g., adk_base)
  • Remote template - Use a remote template (e.g., adk@gemini-fullstack)

Options

The enhance command supports all the same options as create, plus:

--base-template TEMPLATE

Override the base template for inheritance when enhancing your existing project. Available base templates include:

• adk_base - Basic agent template (default)
• langgraph_base_react - LangGraph-based ReAct agent
• agentic_rag - RAG-enabled agent template

Other Options

• --name, -n - Project name (defaults to current directory name)
• --deployment-target, -d - Deployment target (agent_engine, cloud_run)
• --include-data-ingestion, -i - Include data ingestion pipeline
• --session-type - Session storage type
• --auto-approve - Skip confirmation prompts
• And all other create command options

Examples

Basic Enhancement

# Enhance current project with default template
uvx agent-starter-pack enhance

# Enhance with a specific agent template
uvx agent-starter-pack enhance adk@gemini-fullstack

# Enhance with custom project name
uvx agent-starter-pack enhance --name my-enhanced-agent

Advanced Options

# Enhance with specific deployment target
uvx agent-starter-pack enhance adk@data-science --deployment-target cloud_run

# Enhance with data ingestion capabilities
uvx agent-starter-pack enhance --include-data-ingestion --datastore alloydb

# Enhance with custom session storage
uvx agent-starter-pack enhance --session-type alloydb

Base Template Inheritance

# Enhance current project with LangGraph capabilities
uvx agent-starter-pack enhance . --base-template langgraph_base_react

# Enhance with RAG-enabled base template
uvx agent-starter-pack enhance . --base-template agentic_rag

Project Structure Validation

The enhance command validates your project structure and provides guidance:

✅ Ideal Structure:

your-project/
├── app/
│   └── agent.py    # Your agent code
├── tests/
└── README.md

⚠️ Missing /app Folder: If your project doesn't have an /app folder, the command will:

1. Display a warning about project structure
2. Explain the expected structure
3. Ask for confirmation to proceed (unless --auto-approve is used)

How It Works

The enhance command is essentially an alias for:

uvx agent-starter-pack create PROJECT_NAME --agent TEMPLATE --in-folder

It automatically:

• Uses the current directory name as the project name (unless --name is specified)
• Enables --in-folder mode to template directly into the current directory
• Validates the project structure for compatibility
• Applies the same file merging logic as the create command

Base Template Inheritance

When enhancing your existing project (using local@. or local@/path/to/project), the enhance command will:

1. Show current inheritance: Display which base template your project inherits from
2. Provide guidance: Show available alternative base templates and how to use them
3. Support CLI override: Use --base-template to override the base template specified in pyproject.toml

The inheritance hierarchy works as follows:

Your Existing Project
    ↓ (inherits from)
Base Template (adk_base, langgraph_base_react, etc.)
    ↓ (provides)
Core Infrastructure & Capabilities

Use Cases

Prototype to Production:

# You have a prototype agent in /app/agent.py
uvx agent-starter-pack enhance adk@production-ready

Add Infrastructure:

# Add Terraform and deployment capabilities
uvx agent-starter-pack enhance --deployment-target cloud_run

Add Data Pipeline:

# Add data ingestion to existing agent
uvx agent-starter-pack enhance --include-data-ingestion --datastore alloydb

Upgrade Agent Base:

# Upgrade from basic to advanced agent template
uvx agent-starter-pack enhance adk@gemini-fullstack

# Or change base template inheritance
uvx agent-starter-pack enhance . --base-template langgraph_base_react

Automatic Backup

The enhance command automatically creates a complete backup of your project before making any changes:

• Location: .backup_[dirname]_[timestamp] in the parent directory
• Contents: Complete copy of your entire project directory
• Timing: Created before any template files are applied

Best Practices

1. Review Backup: Check that the backup was created successfully
2. Follow Structure: Organize your agent code in /app/agent.py for best compatibility
3. Test Locally: Use --auto-approve in CI/CD but test interactively first
4. Review Changes: After enhancement, review the generated files and configuration

Troubleshooting

"Project structure warning"

• Organize your agent code in an /app folder
• Use --auto-approve to skip the confirmation prompt

"Enhancement cancelled"

• Create an /app folder with your agent.py file
• Re-run the command

"Dependency conflicts"

• Review and resolve conflicts in your pyproject.toml
• Consider using a virtual environment
