[Bug][cyber] False-positive safeguard block stops legitimate cybersecurity assistance mid-session (req_011CcY1kC1p5G4SvH8vm5s6P)

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 blocked message was part of a legitimate defensive-security or security-audit workflow — a class of work explicitly listed as supported in Claude Code's documentation — not a request for offensive or harmful content. The safety filter appears to have triggered on cybersecurity terminology present in the context without evaluating whether the intent and output were defensive, educational, or within an authorized engagement. This pattern produces false positives for security practitioners doing exactly the kind of work Claude Code is documented to assist with, degrading reliability for a clearly in-scope use case.

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 2026-06-29T18:20:14.708Z.
