Claude Code usage limits using agentic coding

I just used Claude Code for a second day using my $20/month Pro plan - very happy! The agentic workflow, which didn't click with me using Windsurf or Amp previously, really worked its magic here.

But, to my surprise, I already hit the usage limit towards the end of the day. The application told me I had to wait an hour before continuing.

Is this how a service for $20/month is supposed to work? This is somewhat strange and disappointing.
