Summary of Changes

Hello @sarojrout, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request adds a new sample AI agent, hello_doctor, designed to simulate a health assessment conversation. Its core purpose is to showcase how an AI can engage in structured, educational health dialogues while strictly adhering to safety protocols, such as disclaiming medical authority and recommending professional consultation. The agent gathers user information through specific questions and provides high-level, non-diagnostic summaries, serving as a robust example of responsible AI application in sensitive domains.

Highlights

• New Sample Agent: Introduces a new hello_doctor health assessment agent sample, demonstrating safe and educational health conversations.
• Structured Health Intake: The agent is designed to ask six key questions (age, smoking, alcohol, medical conditions/medications, allergies, lifestyle) before providing any advice.
• Session State and Risk Assessment: Utilizes log_health_answer to track user responses longitudinally and summarize_risk_profile to provide non-diagnostic risk summaries.
• Safety First: Emphasizes strong safety disclaimers, clearly stating it is not a medical professional and directing users to licensed healthcare providers for real health concerns.
• Few-Shot Examples: Includes examples for handling various scenarios like mild symptoms, concerning symptoms, and supplement questions to guide the agent's behavior.

Code Review

This pull request introduces a new hello_doctor sample agent, which demonstrates a health assessment conversation. The agent is well-structured with clear safety instructions, tools for session state management and risk summarization, and few-shot examples to guide its behavior. The accompanying main.py provides a helpful CLI for running and testing the agent. The code is clean and the sample is a valuable addition. I have one point of feedback regarding the model name used in the agent definition, which might need correction to ensure the sample runs correctly.
