Type of Behavior Issue

Claude refused a reasonable request

What You Asked Claude to Do

I currently do work that is explicitly related to biological threat agents - working on surviellance and monitoring tools - and I can see how this would be difficult to allow, but right now I'm just trying to work on basic human genomic annotation tools and I can't even do that? Surely you aren't restricting Fable from doing anything remotely related to bioinformatics, are you? This renders Fable basically useless for me.

What Claude Actually Did

Demoted me to Opus

Expected Behavior

Fable not even being able to touch anything related to biology is kind of ridiculous
