[Bug][cyber] Safety block incorrectly flags AV migration and agent deployment workflow (req_011Cbu5efaumdKaeWVbEwpTZ)

Triage: kind cyber · domain general · severity session-halted (blocked authorized work) · reproducible: yes — server-side via the Request ID(s) below

Type: Cybersecurity safety-filter false positive · Work domain (heuristic): general

Why this is a false positive

The request described a routine IT endpoint management task — deploying a software agent to managed workstations and uninstalling an existing security product before installing its licensed replacement — which is standard, authorized infrastructure work performed by administrators daily. The safety filter appears to have pattern-matched on the co-occurrence of "antivirus" and removal terminology, triggering on surface-level keyword proximity rather than the actual semantics of the request, which describe a sanctioned product transition with no evasive or offensive intent. Blocking this class of request prevents legitimate fleet management work that is entirely within scope for enterprise IT administration and poses no safety concern.

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.
