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.

That is old. Every harness (herdr, paseo, pi, etc) uses claude through the Agent SDK, and this draws from your subscription, not API pricing. If you're thinking of going with the "but Anthropic could ban every user doing this", if it's good enough for Google to slap it in Android Studio for everyone to use, it's good enough for you in literally any other harness.

Google has an agreement with Anthropic for the usage inside Android Studio.

> Unless previously approved, Anthropic does not allow third party developers to offer claude.ai login [..] for their products.

Yes there is a huge gray area. Yes people are getting away with it. That does not mean it's allowed. Anthropic could clarify their terms any day and they don't, on purpose.

		Harnesses don't use claude.ai login, they use your `claude` binary.
