Why this is a false positive

The assistant was merely listing the contents of an empty local project folder and reporting back that it contained no files — no security-related code, commands, or topics were involved. The cybersecurity safeguard appears to have misfired on a routine directory-listing task with zero cyber content, halting a benign file-navigation workflow and requiring the user to restart the session.

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 2026-07-07T01:26:53.511Z.
