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

Why this is a false positive

The real-time cyber safeguard triggered on a frustrated exclamation directed at the assistant mid-session during a custom VPN multiplexer setup. The prompt addressed no external person or entity and contained no actionable exploitation instructions. Halting the session during network configuration due to non-targeted user frustration creates a false positive on routine system administration 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 2026-08-30T03:32:34.166Z.
