[Bug][cyber] Safety filter halted session on a frustrated exclamation aimed at the assistant, not a security t (req_011Ccmabg7tJKbFLXJuhMWEF)

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 block fired on a brief frustrated exclamation directed at the assistant mid-session (following a session clear), with no cybersecurity content, target, or intent present in the message. This appears to be a false positive where profanity/venting alone triggered the cyber-topic safety classifier, halting an otherwise legitimate session over non-security conversational content rather than any actual security-sensitive request.

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 2026-07-06T22:18:48.277Z.
