Test Driven Development (TDD) with Kiro: this is how it should feel

Engineers at the author's previous organization implemented unit testing to improve code quality, but struggled to consistently apply TDD due to its perceived time-consuming nature and context switching requirements. Kiro, an agentic development tool, supports spec-driven development and hooks to enable enforcement of specific practices like TDD. The author created a Kiro hook to automate the discipline of TDD, enforcing the red-green-refactor cycle by prompting to write failing tests before production code and writing minimal code to pass, then refactoring as needed. This hook runs each time Kiro attempts to save a file, ensuring the TDD process is followed, making TDD feel like a beneficial practice rather than a burden.
