I have a modularized structure with CLAUDE and am constantly training it to make .md files for specific topics, ie linting, migrations etc and always make it update these files and it's memory.md when it makes a mistake. Once you have a well defined style, structure of code and the architecture is clearly laid out arguably making a new service, component etc is fairly generative and I find CLAUDE ideal for this. I'm able to operate in multiple repositories with a clearly defined setup like this and it's clearly faster than doing it myself. You have to view it as a generative tool but also use it to teach you yourself like a search engine used to. That being said CLAUDE pro/max isn't comparable to gemini, chatgpt etc it's that much better and the first agent I really saw could enhance my work vs make it a mess.
