Why this is a false positive

The conversation leadup consisted only of short repeated placeholder-style messages with no security, exploit, or hacking terminology present. The cybersecurity safeguard nonetheless fired and halted the entire session, requiring the user to edit or restart rather than continue benign work. This indicates the classifier is triggering on low-information/repetitive input patterns rather than actual cyber-related content, producing a disruptive false positive.

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 2026-07-06T22:19:30.773Z.
