Antigravity Environment Config (Interactions)

Two non-default ways to control the Antigravity sandbox:

Option	When to use
Reuse by id (`"env_<id>"`)	Agent needs to build on prior work in the same sandbox (iterative project). State remains available while that environment ID is valid; inactive environments expire.
Full `EnvironmentConfig` dict	Need a specific source repo, package set, or network policy.

The dict shape follows Google's environment schema. Only the keys you set are sent; the API applies defaults for the rest.

Code

from os import getenv

from agno.agent import Agent
from agno.models.google import GeminiInteractions

# Reuse an existing environment by id
agent_reuse = Agent(
    model=GeminiInteractions(
        agent="antigravity-preview-05-2026",
        environment=getenv("ANTIGRAVITY_ENVIRONMENT_ID"),
    ),
    markdown=True,
)

# Full EnvironmentConfig
agent_custom = Agent(
    model=GeminiInteractions(
        agent="antigravity-preview-05-2026",
        environment={
            "type": "remote",
            "sources": [
                {"type": "repository", "source": "https://github.com/agno-agi/agno", "target": "/workspace/agno"},
            ],
        },
    ),
    markdown=True,
)

if __name__ == "__main__":
    # Reuse is optional: supply a real, still-valid ID to run this part.
    if getenv("ANTIGRAVITY_ENVIRONMENT_ID"):
        agent_reuse.print_response(
            "Continue the project we started last time and ship the next "
            "iteration of the report."
        )

    agent_custom.print_response(
        "Skim the repo we cloned, summarize the module layout, and save "
        "the summary to STRUCTURE.md inside the sandbox."
    )

The script always runs the custom repository example. To run the reuse example too, set ANTIGRAVITY_ENVIRONMENT_ID to an existing environment ID. Omitted network configuration uses the provider default; use its documented network.allowlist when restricting outbound access.

Usage

Set up your virtual environment

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

Set your API key

export GOOGLE_API_KEY=xxx

Install dependencies

uv pip install -U "google-genai>=2.3" agno

Run Agent

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

python antigravity_environment_config.py
