Claude Code is very good; good enough that I upgraded to the Max plan this week. However, it has a long way to go. It's great at one-shotting (with iterations) most ideas. However, it doesn't do as well when the task is complicated in an existing codebase. This weekend I migrated the backend for the SaaS I am building from Python to .NET Core. It did the migration but completely missed the conventions that the frontend was using to call the backend. While the converion itself went OK, every user journey was broken. I am still manually testing every code path and feeding in the errors to get Claude to fix it. My instructions were fairly comprehensive but Claude still missed most of it. My fault that I didn't generate tests first, but after this migration that's my first task.
