You can still read the code, ask the AI questions about it, and ask it to fix things. Coding agents are a power tool for cleaning up codebases, but you have to ask for the right cleanups, which means figuring out what it is based on your understanding. (You can also ask the AI to suggest ideas.)
This takes time away from implementing new features, but that’s true of all code health maintenance.

This only works in small projects. For large projects, it is close to impossible. Everybody talks about how new models appear all the time and nobody comments on the fact that context size has almost stalled.
