> (You can’t use your Claude subscription.)
How come?
The Claude subscription does not include Claude API usage.
Claude behaves in Claude Code somewhat differently vs other coding harnesses (sometimes it's a remarkable improvement) connected directly via api. Also, it cost more than the subscription. There's quite a bit of baked in tooling and assumptions in Claude code that may be good for you, or unhelpful based on what you are doing.
You’d need to use Claude API pricing (pay as you go, not a subscription).

Anthropic only authorizes their own Claude code to be used with a subsidized subscription.
They want you to use and get accustomed to only their own tools. If other coding harnesses were allowed, it's far too easy to switch providers.
They can't allow that, because they only have a few months of head start.
So everyone accepts Claude code which is required for these sweet subsidized tokens.
