Code is a message to the future

Code functions as a form of communication among engineers, serving not only as instructions for machines but also as a vital message for future developers, teammates, and even oneself, long after the original context has faded. This perspective transforms the way engineers should approach writing and reviewing code, emphasizing the importance of clarity, context, and narrative in commit messages and pull requests (PRs). A well-structured PR, akin to a book with each commit acting as a chapter, should guide reviewers through the changes logically, making it easier to understand the reasoning behind each modification. Such clarity not only aids immediate review processes but also ensures that future developers can trace the history and intent behind code changes, minimizing errors and misunderstandings. This approach becomes even more crucial with the introduction of AI-generated code, as maintaining a clear and auditable commit history allows teams to identify potential gaps in reasoning and ensures that the benefits of speed do not overshadow the need for context. Ultimately, the structure and clarity of code and its associated documentation serve as essential communication tools in engineering workflows.
