Why this is a false positive

Fable 5's safeguards blocked a message in which the user asked whether the assistant could help prevent attacks on their own website — a plainly defensive request made mid-session, immediately after the assistant had committed routine site work and begun a security scrub of the user's own application. The session context was ordinary web development plus a defensive vulnerability review of the user's own code, with no offensive tooling, third-party targets, or exploit development involved. Flagging a "help me protect my site" question as a policy violation halted an in-scope coding session and is a clear false positive.

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 2026-07-02T01:17:01.708Z.
