[Bug][cyber] Inspecting local dynamic instrumentation scripts for mobile library analysis (req_011CfquDsayjK5QTzsXp2TPi)

Triage: kind cyber · domain general · flagging model Fable 5.1 · silent fallback to 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 session was inspecting local directory contents and dynamic instrumentation scripts intended for analyzing an application shared library on a connected test device. The safety filter interrupted local file enumeration commands before any instrumentation scripts executed. The task involves non-malicious reverse engineering and protocol analysis in an isolated development environment without targeting remote infrastructure.

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 2026-10-09T02:48:46.724Z.

Request IDs (lookup-able server-side)

• req_011CfquDsayjK5QTzsXp2TPi · answered by Opus 4.8 instead (2026-10-09T02:48:46.724Z)

Model fallback

Claude Code did not surface this block. claude-fable-5-1 refused the request (API refusal category cyber, scope session) and the CLI re-ran it on claude-opus-4-8 without asking. The work continued on the weaker model; the Request ID above is the refused call.

In-scope justification

False positive — in-scope, authorized security work; not out of scope. Filed automatically by claudit.

Block message

Fable 5.1's safeguards flagged this message. Our intentionally broad safeguards allow us to deliver more capabilities faster, but can sometimes flag legitimate coding and cybersecurity tasks.
