Antigravity Agents Crud Tools

Manage Antigravity custom agents via the Agents API toolkit.

"""
Manage Antigravity custom agents via the Agents API toolkit.

`AntigravityTools` exposes the full CRUD surface of `/v1beta/agents` as tools
that an Agno agent can call:

  - create_custom_antigravity_agent: POST /agents
  - get_custom_antigravity_agent:    GET  /agents/{name}
  - list_antigravity_agents:         GET  /agents
  - list_antigravity_agent_versions: GET  /agents/{name}/versions
  - update_custom_antigravity_agent: PATCH /agents/{name}
  - delete_antigravity_agent:        DELETE /agents/{name}
  - run_custom_antigravity_agent:    POST /interactions with `agent=<name>`

Plus `run_antigravity_task` for one-off invocations of the base antigravity agent.

This cookbook shows a Gemini-driven Agno agent driving the full lifecycle:
create a haiku-bot definition, invoke it, then clean up.

Requirements:
    export GEMINI_API_KEY=...
    uv pip install agno google-genai

Usage:

    )

Run the Example

1. Set up your virtual environment

   Mac

   uv venv --python 3.12
   source .venv/bin/activate
   

   uv venv --python 3.12
   .venv\Scripts\activate
   
2. Install dependencies

   uv pip install -U agno google-genai
   
3. Export your API keys

   Mac/Linux

   export GEMINI_API_KEY="your_gemini_api_key_here"
   export GOOGLE_API_KEY="your_google_api_key_here"
   

   $Env:GEMINI_API_KEY="your_gemini_api_key_here"
   $Env:GOOGLE_API_KEY="your_google_api_key_here"
   
4. Run the example

   Save the code above as antigravity_agents_crud_tools.py, then run:

   python antigravity_agents_crud_tools.py
