AI Summary

• Introduction: Duncan reviews the Cursor AI editor and its application in Test-Driven Development (TDD) using Kotlin, aiming to demonstrate strict TDD principles.

• Setup:

  • The session involves the integration of an AI agent into the coding process.
  • Agent mode is enabled in Cursor, allowing the AI to run commands within the development environment.

• Creating Guidelines:

  • The AI is tasked with generating project guidelines, reinforcing the use of TDD.
  • Juni analyzes the project structure and creates a guidelines.md file outlining project details and development guidelines.

• Task Execution:

  • Duncan instructs the AI to run tests after each code change and to provide feedback on failures.
  • The AI attempts to implement the simplest code necessary to pass tests while adhering to TDD principles.

• Interactions with the AI:

  • Throughout the session, Duncan and the AI interact to refine code and adjust tasks.
  • The AI demonstrates responsiveness but sometimes must be corrected or guided to adhere to the intended coding principles.

• Behavior of the AI:

  • The AI proactively tries to optimize and refactor code but occasionally misinterprets instructions, leading to unintended modifications.
  • Duncan emphasizes the importance of maintaining control and guiding the AI’s actions during development.

• Conclusion:

  • The overall experience showcases the potential of AI in enhancing productivity in software development while highlighting the need for human oversight in ensuring code quality.
  • Duncan expresses enthusiasm for future developments and improvements of the AI tools within the coding environment.
