Is that still needed now that Agent SDK usage is included in subscriptions?

Update October 7, 2026: Claude Max, Ultra, and Team plans now include monthly API credits. They cover the Claude API, Claude Managed Agents, and the Claude Agent SDK and claude -p when you run them with an API key from your linked Claude Console organization. Nothing changes for your plan: when you’re signed in with your Claude plan, the Claude Agent SDK and claude -p still draw from your subscription limits.
EDIT: I was mistaken. pi uses @anthropic-ai/sdk (the client for the Messages API), not @anthropic-ai/claude-agent-sdk (the Agent SDK).
