[Bug][aup] Safeguards block fired on a frustrated exclamation while hardening API error handling (req_011CccMah86E4MUwi4Gpjgn1)

Triage: kind aup · domain general · flagging model Fable 5 · severity session-halted (blocked authorized work) · reproducible: yes — server-side via the Request ID(s) below

Type: AUP / Usage-Policy block (false positive) · Work domain (heuristic): general

Why this is a false positive

The safeguard fired on a frustrated exclamation the user directed at the assistant mid-session after repeated blocks; no person was addressed and the message contained no request for harmful content. The surrounding session was legitimate, in-scope defensive work — hardening a web application by removing raw error-message leakage to clients and verifying parameterized database queries. Blocking the entire coding session over a user venting at the tool is a disruptive false positive that interrupts routine security-hardening work.

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 2026-07-02T01:22:50.257Z.
