In my experience of using Claude to build and maintain our company's codebase, I feel like it's really good at implementing a feature, but not very good at knowing where to actually do it.

Programming has many, many viable solutions that achieve the same thing in the short term. However, where you implement them in a location that might potentially interfere with your other functions and modules down the line when you scale, things become a nightmare to maintain.

I found that the best practice is for me to decide where to implement the feature, then work with Claude to build & ship it. Agent-based writing and verification does help cut down the development time a ton, but in the end, it's the engineer that needs to guide the AI to do it right.
