Just pasting code snippets, and occasionally an entire file or two into the main claude.com site. I usually already know what I want and need, but just want to speed up the process on how to get there, and perhaps I missed something in the process.

Aider is pretty good way to automate that. You can use it with Claude models. It lets you be completely precise down to a single file, and sit in chat/code/review loop - but it does a lot of the chores, like generating commit messages etc while saving you the copy paste effort.
