Antigravity Agent 09-2026: Released antigravity-preview-09-2026, which replaces and deprecates antigravity-preview-05-2026.

If you run on a remote sandbox (environment: "remote") and read only output_text or model_output steps, update the agent string and nothing else changes.

If you run tools locally (local_environment) or parse function_call steps, the built-in tools changed. Parameters use PascalCase instead of snake_case, and file edits use line-range replacements instead of full rewrites.
