[adamfweidman]

Summary

This PR enables the ADK agent session for non-interactive mode by default in settings and logs its usage.

Details

• Added adk.agentSessionNoninteractiveEnabled: true to .gemini/settings.json.
• Added a debug log in nonInteractiveCli.ts when using the ADK agent session.

Related Issues

None.

How to Validate

1. Run the CLI in non-interactive mode.
2. Check the debug logs to see [ADK] Running non-interactive mode with ADK agent session.

⚠️ Invocation Drift Warning

The following file pairs should generally be kept in sync during the AgentSession migration:

• non-interactive CLI: packages/cli/src/nonInteractiveCli.ts was modified but packages/cli/src/nonInteractiveCliAgentSession.ts was not.

If this is intentional (e.g., a bug fix specific to one implementation), you can ignore this comment.

This check will be removed once the legacy implementations are deleted.

Code Review

This pull request provides a comprehensive architectural design and alignment documentation for migrating the Gemini CLI backend to the Agent Development Kit (ADK). The documentation includes detailed field-by-field mappings, architecture notes for both ADK and the existing CLI, a cross-SDK comparison to validate the proposed event taxonomy, and a high-level migration design document. Additionally, a minor code change was implemented in packages/cli/src/nonInteractiveCli.ts to include a debug log when running in non-interactive mode with an ADK agent session. There are no review comments to address, and I have no further feedback to provide.
