All tests green, static analysis clean, and the condition was a business rule with history. My review caught it. Barely.</p> <p>That came out of an experiment I ran this month: a coding agent on one legacy PHP module, since agents can do multi-file changes now and every old codebase suddenly looks like a target.</p> <p>The setup matters more than the model. I did not ask &ldquo;modernize this&rdquo;. I gave a narrow migration goal on one bounded module: replace a deprecated API, add proper namespaces, keep behavior. The same shape of task I would give to Rector. The difference is that the agent also handles the irregular cases Rector cannot express, the places where people wrote creative code in 2015.</p> https://useinov.com/posts/2023/ai-assistants-limits/ Sat, 23 Dec 2023 10:40:00 +0300 https://useinov.com/posts/2023/ai-assistants-limits/ <p>A DTO with a dozen fields, a framework migration, a slow query incident. Three tasks from the last few months, all done with Copilot and ChatGPT open. Here is where the line runs for me.</p> <p>Task one, boilerplate. The DTO, its validation rules, a test with fixtures. The assistant writes this faster than I type, and the result needs only a quick read. Same for converting an array-shaped legacy structure into typed classes. This is honest time saved, maybe an hour a day. The code is the kind where being generic is correct.</p>
