## What I'd like help with

I watched this video and want to try it. Walk me through it one step at a time, and check the official links below before giving exact commands, since they change.

## In plain English

Claude just got 90% cheaper: Haiku 5.5 is Anthropic's fastest model, $0.10 per million tokens in and $0.50 out, and Max plans get monthly API credits this week ($100 on Max 5x, $200 on Max 20x). The 90% is for requests up to 100K tokens. Would you switch your agents to it?
