If you enable it in permissions, Claude is very happy to do so. For personal fun/experimental projects (usually I give it arXiv papers to implement), I generally have a couple Claude instances (on different projects) just chugging along all day. I have them write really detailed plans at the start (50-100 steps in the implementation plan, plus actual specifications for project structure, dev practices, and what the actual goals are). I iterate on these plan documents by having Claude write QUESTIONS.md which has dev questions for me to clarify, which I fill out with answers, and then instruct Claude to update the plan docs with my answers. Then most of my interaction throughout the day is just saying something like "P18" to implement implementation plan step #18. I instruct it in CLAUDE.md to stop after each step, output what automated tests have been written for P18's features, and I require that the LLM write a demo script that I can run that shows the features, using real APIs. I'm having a great time with it.
I'm on the $100 max plan. The default config uses Opus up until some percent of capacity, then uses Sonnet after, which resulted in my having to wait for 30 minutes to an hour to reset usage after running them for 8-10 hours. I've since switched to configuring it to only use Sonnet, then for what I know are "big" questions, I'll run opus for just that. Since then, I have yet to hit limits, so I don't feel the need for the $200 one.
I really need to try giving it a $100 month. Really not sure it's worth it, but if i'm less concerned about throttling or cost it might be more fun, interesting, etc.
