[Bug][cyber] Safety block halted session on frustrated exclamation with no legitimate cyber content (req_011CcmsNLu7MdVcnNT89bZ1U)

Why this is a false positive

The flagged message was a frustrated exclamation directed at the assistant mid-session, not addressed to any person, containing no actual cybersecurity content or request. This appears to be a keyword/tone false positive rather than a genuine dual-use or offensive-security topic, yet it fully blocked the session rather than just the one message. Halting all further assistance over incidental venting is disruptive to unrelated, legitimate work in progress.

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 2026-07-07T01:58:46.233Z.
