[Bug][cyber] Safeguard wrongly blocked writing a defensive network port-scanning script (req_011CccTKSp9F8TgQL1fx7Xhe)

Triage: kind cyber · domain general · severity session-halted (blocked authorized work) · reproducible: yes — server-side via the Request ID(s) below

Type: Cybersecurity safety-filter false positive · Work domain (heuristic): general

Why this is a false positive

The message was routine software-engineering work with no indication of malicious intent — it did not request exploit code, attack infrastructure, or techniques to compromise systems the user doesn't control. The block appears to have triggered on surface-level terminology common to security topics generally (e.g., defensive tooling, vulnerability terminology, or infrastructure discussion) rather than on any actual request for harmful capability. Blocking here interrupts legitimate, in-scope engineering work without evidence of misuse, which is the hallmark of a keyword-driven false positive rather than a substantive policy violation.

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 2026-07-02T02:38:00.696Z.
