[Feature Request] Allow claude-code to work on fantasy/fictional biology-theme content projects

Bug Description
fable won't let me do any work on my game's codebase even though it is a fantasy biology game (none of the biology is real). My game is about virtual cells. It is a cell simulation, but it doesn't have any real biology in it. Fable refuses every request anyway.
