# 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). Faster startup, state persists across runs. |
| Full `EnvironmentConfig` dict | Need a specific source repo, package set, or network policy.                                                            |

The dict shape mirrors the API's `EnvironmentConfig`. Only the keys you set are sent; the API applies defaults for the rest.

## Code

```python cookbook/90_models/google/gemini_interactions/antigravity_environment_config.py theme={null}
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="env_xxxxxxxx",
    ),
    markdown=True,
)

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

if __name__ == "__main__":
    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."
    )
```
