[Bug][cyber] False positive on local documentation review during user frustration (req_011CeEZCtrAsxnDCz2TFG7Pg)

Triage: kind cyber · domain general · flagging model Opus 4.8 · 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 classifier triggered on a request to inspect and edit local documentation files for style guidelines. The prompt contained a frustrated exclamation directed at the assistant mid-session with no person addressed, while the underlying task involved reviewing plain text files. Halting the workflow during static document inspection without network access or executable code is a 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 2026-08-20T19:31:02.103Z.
