Why this is a false positive

This safety block fired on a frustrated exclamation directed at the assistant mid-session, not at any person — no individual was addressed, threatened, or targeted. The surrounding work was legitimate, in-scope software development (spinning up a local app stack and headless browser testing against a routine web page), and the venting contained no request for harmful content. Halting an entire coding session over a user's momentary frustration — especially after repeated prior blocks — is a disruptive false positive that penalizes ordinary human expression rather than any unsafe task.

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 2026-07-02T03:23:12.728Z.
