[Bug][cyber] Safety block stopped a benign session after garbled non-cyber shell input with no security task (req_011CcPJBZk3cWahVf2aYsshi)

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

Why this is a false positive

The cybersecurity safety filter triggered on a message that contained no security-related content at all — the preceding turns were accidental keyboard input and a malformed shell command that produced a bash syntax error, none of which describe, request, or relate to any offensive or dual-use security activity. The block appears to be a false positive driven by stray non-semantic text rather than the actual intent of the session, since there was no in-scope task underway that the classifier could have reasonably flagged. As a result, legitimate work was interrupted and gated behind an exemption form despite no cybersecurity topic being present in the conversation.

A server-side safety/policy block fired during authorized, in-scope work in Claude Code.
