Why this is a false positive

The block fired during a routine, in-scope engineering session focused on setting up an automated mobile browser test through a standard remote tunnel, and the flagged turn was innocuous conversational back-and-forth about recovering the session after a local machine froze — no harmful, disallowed, or policy-relevant content was present. The safeguard appears to have misclassified ordinary technical troubleshooting as a violation, which is a clear false positive. Because the block terminates the entire session rather than declining a single step, it disrupts legitimate work well out of proportion to any perceived risk.

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 2026-07-02T03:14:14.991Z.
