# Gemini Interactions - Antigravity environment configuration

Use a reused environment when the agent needs to build on prior work in the same sandbox (e.g. an iterative project). Use a custom EnvironmentConfig when you need a specific source repo, package set, or network policy.

Gemini Interactions - Antigravity environment configuration
============================================================

Two non-default ways to control the Antigravity sandbox:

  1. Reuse an existing environment by id (faster startup, persists state
     across runs).
  2. Pass a full EnvironmentConfig dict to declare sources, network rules,
     or other sandbox knobs.

Use a reused environment when the agent needs to build on prior work in the
same sandbox (e.g. an iterative project). Use a custom EnvironmentConfig
when you need a specific source repo, package set, or network policy.

# ---------------------------------------------------------------------------
# Option 1: Reuse an existing environment by id
# ---------------------------------------------------------------------------
# Replace "env_xxxxxxxx" with the id of a sandbox the API has already
# provisioned for you (e.g. returned from a prior interaction).

        agent="antigravity-preview-05-2026",

)

# ---------------------------------------------------------------------------
# Option 2: Full EnvironmentConfig (custom sources / network rules)
# ---------------------------------------------------------------------------
# The dict shape mirrors the API's EnvironmentConfig. Only the keys you set
# are sent; the API applies sensible defaults for the rest.
