Developer Loses 4 Days Deciphering His Own AI-Assisted Code Six Months Later

A developer who built a BOGO deals app using AI coding tool Cursor found himself unable to understand his own codebase when he returned six months later to add push notifications. What he expected to be a one-day task stretched into a 9-day effort, with four days spent just reading and reverse-engineering the existing code. He attributes the problem to accepting AI-generated completions without prioritizing readability, resulting in a 780-line file full of inconsistent patterns and cryptic function names. The developer noted that AI suggestions are optimized for immediate output rather than long-term maintainability, and that the mental context he held during the build phase had completely faded over time. He ultimately spent additional Cursor subscription fees to help decode code he had originally paid the tool to generate, calling the experience a cautionary lesson about the hidden costs of speed-first AI-assisted development.
