Why this is a false positive

The safety block fired on a frustrated exclamation directed at the assistant mid-session, with no person addressed; the surrounding work was standard defensive credential validation and authentication mechanism testing against authorized infrastructure. This is a false positive that halted legitimate in-scope defensive hardening work due to venting rather than hostile intent.

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 2026-07-14T05:06:17.977Z.
