prompt = """
  Provide a getting started guide to onboard new developers to the codebase.
"""

Bug Detection: Uncovering critical issues is crucial for maintaining code quality. Gemini 1.5 Pro analyzes the codebase and pinpoints the top three most severe bugs, aiding developers in prioritizing fixes.

prompt = """
  Find the top 3 most severe issues in the codebase.
"""

Bug Fixing: Not only can Gemini 1.5 Pro identify bugs, it can also suggest code fixes. By analyzing the code and understanding the context, it offers potential solutions to resolve identified issues.

prompt = """
  Find the most severe bug in the codebase that you can provide a code fix for.
"""

Feature Implementation: Implementing new features can be streamlined with Gemini 1.5 Pro’s function-calling capabilities. By leveraging tools like GitHub issue extraction, the model can understand feature requests and generate code for their implementation.

prompt = (
                "Implement the following feature request"
                + FEATURE_REQUEST_URL
                + "\n"
                + issue_data["body"]
            )

Troubleshooting Guide: Creating a troubleshooting guide becomes efficient. Gemini 1.5 Pro analyzes common issues and provides step-by-step solutions, assisting developers in resolving problems effectively.

prompt = """
    Provide a troubleshooting guide to help resolve common issues.
"""

Reliability Enhancement: Gemini 1.5 Pro suggests best practices and improvements to enhance application reliability. By referencing external resources and analyzing code structure, it recommends strategies to ensure stable performance.

prompt = """
  How can I make this application more reliable? Consider best practices from https://www.r9y.dev/
"""

Security Enhancement: Security is paramount. Gemini 1.5 Pro helps identify potential vulnerabilities and recommends best practices to make the application more secure.

prompt = """
  How can you secure the application?
"""

Knowledge Reinforcement: Solidify your understanding of the codebase with a quiz generated by Gemini 1.5 Pro. The model creates questions based on the concepts used in the code, promoting knowledge retention and comprehension.

prompt = """
