Dev finds Claude subscription limits reject any prompt outside Claude Code, contradicting docs

lucasmeijer · x · 2026-10-20

Developer lucasmeijer publicly challenged Anthropic's subscription policy: an Oct 7 update stated "You can still use the Claude Agent SDK, claude -p, and third-party apps with your subscription limits," but he found that any subscription-powered prompt not starting with "You are Claude Code, Anthropic's official CLI for Claude." gets rejected.

His question to Anthropic: "Should I believe docs or api?" The discrepancy suggests third-party tool access to Claude subscription quotas is far more restricted than officially documented — directly affecting paying users relying on the SDK and third-party clients.
