Feature request: Implementing gemini agent out of the box

[callmeUmer]

Use case

Introduce out-of-the-box support for the Gemini agent, similar to OpenAI, Anthropic, and other existing agents. Given Gemini’s position as one of the major stakeholders in generative AI, integrating it into Agent-Squad would be highly valuable. The implementation would be straightforward, enabling users to import the agent as:

from agent_squad.agents import GeminiAgent

Solution/User Experience

From a user’s perspective, integrating Gemini should feel seamless — as simple as importing and using GeminiAgent, just like with OpenAI or Anthropic agents. I am willing to contribute and work on this feature, as it directly supports my use case.

Hi! I've submitted an implementation for this in PR #451. The GeminiAgent follows the same pattern as OpenAIAgent, using the google-genai SDK with support for streaming/non-streaming, system prompts, retriever integration, and a new gemini optional dependency group.

I'd love to be assigned to this issue if possible. Would appreciate a review from @brnaba-aws or @cornelcroi when you get a chance!

The scope would be easier to review if the first version defined a small acceptance contract for Feature request: Implementing gemini agent out of the box. I would call out the default behavior, the migration/backwards-compatibility story, and one or two cases that are intentionally out of scope so the implementation does not grow beyond the original request.
