Claude Agent SDK now bills

Short summary

The Claude Agent SDK (Python and TypeScript) can bill against your Pro/Max subscription instead of API credits—just use an OAuth token from `claude setup-token` instead of API keys. Setup takes ~5 minutes: generate the token, export CLAUDE_CODE_OAUTH_TOKEN, and use it with the SDK. Includes worked examples and a reference repo showing both languages, plus auth precedence rules to avoid accidentally double-billing.
