Spec-driven development: Using Markdown as a programming language when building with AI

AI coding agents like GitHub Copilot can simplify the software development process by automating code generation from structured specifications written in Markdown, as demonstrated by the example of the GitHub Brain MCP Server project. This approach uses a combination of documentation and code specifications contained in files like README.md and main.md, which are then processed by AI to generate the actual code in a target language such as Go. The workflow involves updating specifications for new features or bug fixes and invoking the AI to compile these into executable code, with tools like Spec Kit providing a framework for spec-driven development. While this method reduces the need to directly manage code, challenges include ensuring specifications are clear and updated, and managing the growing complexity of compiled code. The process highlights the potential of AI to streamline code development, though testing remains essential to verify the intended behavior, and further exploration is needed to assess the flexibility of regenerating code in different languages.
