That's true for new projects, I've found that as a bootstrap mechanism it is not ideal, takes away your hard earned preferences/know-how abs leaves you barely engaged on the technical path. On the other side I already have quite big codebases, some legacy and inherited, there exist vast amount of context to work on and figure out stuff/fixes/bugs/improvements and Claude Code excels 95% of the time in figuring the existing flows and functionality, if a vague or precise issue is known that's facing some files elaborations or user work flows it can do a good job in pointing out what are, with a high chance, the issues.
