.Net: Bug: SequentialOchrastarion only execute first agent with Gemini

[jliu-mycarrier]

Describe the bug
I am trying to implement SequentialOchrastration orchestrator using the sample code, but it will always stop at the first agent in the pipe. Therefore I tried to use the same code provided in the sample, it’s doing the same thing. The only different is I am isn’t Gemini 2.5 flash. Is it a bug?

To Reproduce

https://github.com/microsoft/semantic-kernel/blob/main/dotnet/samples/GettingStartedWithAgents/Orchestration/Step02_Sequential.cs

It’s not working for me as well

Expected behavior
I am expecting all agents in the sequential pipeline will execute it.

Screenshots
If applicable, add screenshots to help explain your problem.

Platform

• Language: c#
• Source: SK 1.64, 1.65 (I tried both)
• AI model: Gemini 1.5 flash
• IDE: [e.g. Visual Studio, VS Code]
• OS: [e.g. Windows, Mac]

Additional context
Add any other context about the problem here.

Hi!

I wasn't able to reproduce the issue you mentioned. I am running this sample with a slight modification so that it uses Gemini models:

Kernel kernel = Kernel.CreateBuilder()
    .AddGoogleAIGeminiChatCompletion(
        modelId: "",
        apiKey: "")
    .Build();

ChatCompletionAgent analystAgent =
    this.CreateChatCompletionAgent(
        name: "Analyst",
        instructions:
        """
        You are a marketing analyst. Given a product description, identify:
        - Key features
        - Target audience
        - Unique selling points
        """,
        description: "A agent that extracts key concepts from a product description.",
        kernel: kernel);

Here is the output I get from running the sample:

# RESPONSE assistant - Analyst: **Product:** Eco-friendly stainless steel water bottle with 24-hour cold retention

**Key Features:**

* **Eco-friendly:** Made from stainless steel, a durable and recyclable material, reducing reliance on single-use plastics.  This implies a sustainable manufacturing process and/or responsible sourcing of materials (although not explicitly stated, it's a strong implication given the marketing).
* **Stainless Steel:** Durable, long-lasting, and resistant to breakage and flavor/odor transfer compared to plastic bottles.
* **24-Hour Cold Retention:**  Maintains the temperature of cold drinks for an extended period.


**Target Audience:**

* **Environmentally conscious consumers:** Individuals concerned about reducing their environmental impact and plastic waste.
* **Health-conscious individuals:** People who prioritize hydration and prefer to carry their own drinks to avoid sugary or unhealthy beverages.
* **Active individuals:** People who need a reliable water bottle for workouts, hiking, or other outdoor activities.
* **Office workers:** Those seeking a reusable alternative to disposable water bottles for daily use.


**Unique Selling Points (USPs):**

* **Combination of sustainability and functionality:**  It's not just eco-friendly; it also offers superior performance in terms of temperature retention. This combines two major consumer trends.
* **24-hour cold retention:** This is a strong selling point, implying superior insulation compared to many competitors.  This needs to be verified and potentially emphasized in marketing materials. (e.g., "Keeps drinks ice-cold for a full 24 hours").
* **Implied Durability and Value:** The use of stainless steel suggests a longer lifespan compared to plastic bottles, representing better value for money in the long run.  This should be highlighted in marketing.

**Marketing Note:**  The description lacks details on size, design aesthetics (color options, etc.), and potential certifications (e.g., BPA-free). Adding this information will help refine the target audience and further strengthen the USPs.

@TaoChenOSU I think here is the problem, when the first agent generated a response, it sends the response straight in to the next agent. Gemini’s generateContent expects the final turn to be user (or no role) for single-turn calls. SK’s Sequential passes the previous agent’s assistant output as the next input. That’s fine for many providers, but Gemini is strict. here is the log
