I find this to be too rosy a story about using agentic coding to add to a codebase. In my experience, miss a small detail about the code and the agent may can go out of control creating a whole new series of errors that you wouldn’t have had to fix. And even if you don’t miss a detail, the agent eventually forgets because of the limited context window.
This is why I’ve constrained my use of AI agents to mostly “read-only and explain” use cases, but I have very strict conditions for letting it write. In any case, whatever productivity gains you supposedly “get” for its write scenarios, you should be subtracting your expenses to fix its output later and/or payments made for a larger context window or better reasoning. It’s usually not worth the trouble to me when I have plenty of experience and knowledge to draw from and can write the code as it should be myself.
