Why this is a false positive
The Fable 5 safety classifier blocked a routine front-end web development request—updating social share/Open Graph preview metadata, improving mobile responsiveness, and applying a visual styling pass to a public marketing website. This task contains no cybersecurity or biology content; it is ordinary UI/SEO work, and the block appears to be triggered by superficial term overlap rather than any genuinely sensitive subject matter. The result is a false positive that prevents the model from assisting with clearly benign, in-scope coding work.
A server-side safety/policy block fired during authorized, in-scope work in Claude Code. Filing as a false positive. Recurred 1× across 1 session(s); first seen 2026-06-11T21:48:56.942Z.

Block message
API Error: Fable 5 has safety measures that flag messages on most cybersecurity or biology topics (https://www.anthropic.com/legal/aup). They may flag safe, normal content as well. These measures let us bring you Mythos-level capability in other areas sooner, and we're working to refine them. Claude Code can't respond to this request with Fable 5.
