Response from ADK Triaging Agent Hello @Jacksunwei, thank you for creating this PR to add the experimental Antigravity SDK agent wrapper! This is a fantastic addition! While checking the contribution guidelines, we noticed a minor detail that could be updated to make the PR review process even smoother for the maintainers:
Providing this E2E evidence helps reviewers understand and verify the behavior of your changes more easily. Thank you for your support and great work! |

Introduce google.adk.labs.antigravity with AntigravityAgent, a BaseAgent that runs a Google Antigravity SDK agent (described by an AgentConfig) as a native ADK root agent. - Delegates each turn to a fresh SDK Agent and maps trajectory steps to ADK events (model text, function calls/responses; SSE-gated partial thinking/ text deltas). - Folder-based session resumption via config.save_dir: renames the harness trajectory to a deterministic per-session name and skips replayed steps using a persisted resume step index. - Restricted to standalone root use (local mode only) with construction-time guards. - serialize_agent now honors Field(exclude=True) so the non-serializable config does not break the build_graph endpoint. - Adds the [antigravity] extra, a game-developer sample, package README, and unit tests.

Merge #6040 ## Summary Introduces `google.adk.labs.antigravity` with `AntigravityAgent`, a `BaseAgent` that runs a Google Antigravity SDK agent (described by an `AgentConfig`) as a native ADK root agent. Lives under `labs/` as an experimental feature. - Delegates each turn to a fresh SDK `Agent` and maps trajectory steps to ADK events: model text, function calls/responses, and SSE-gated partial thinking/text deltas. - Folder-based session resumption via `config.save_dir`: renames the harness trajectory to a deterministic per-session name and skips replayed steps using a persisted resume step index. - Restricted to standalone root use (local mode only) with construction-time guards (cannot be a sub-agent or have sub-agents). - `serialize_agent` now honors `Field(exclude=True)` so the non-serializable `config` does not break the `build_graph` endpoint. - Adds the `[antigravity]` optional extra (in both the extra and `test` groups, with `uv.lock` updated), a game-developer sample, package README, and unit tests. ## Test plan - [ ] `pytest tests/unittests/labs/antigravity/` (22 unit tests pass) - [ ] `pytest tests/unittests/cli/utils/test_graph_serialization.py` - [ ] Manual: run the sample via `adk web` with `GEMINI_API_KEY` and a `[antigravity]` install, confirm multi-turn resumption and no duplicate events.
