Fable 5 in Agent mode

Where does the bug appear (feature/product)?

Cursor CLI

Describe the Bug

Pro+, API pool 0% of $70. No BYOK (confirmed: no Anthropic key in Settings, no Windows env vars).
Fable 5 fails immediately with Anthropic error: “Your credit balance is too low to access the Anthropic API”.

Looks like Fable routes to Anthropic direct billing instead of Cursor included API pool.
