Start by reviewing the reported Feedback ID and reproducing the insufficient-credit error in Claude Code on macOS using the stated account balance and iTerm environment. Done means identifying whether the failure is client-side or account-side and confirming that valid available funds no longer trigger this error, or documenting the external cause.
