Description

**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 safeguard interrupted a session coordinating seven subagents executing unit tests and component helper validation. The triggering user input was a short status inquiry containing no exploit payloads, network requests, or system commands. Halting the entire session for a benign user query creates a false positive that breaks active background agent workflows.

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 2026-08-31T15:03:58.926Z.

### Request IDs (lookup-able server-side)
- `req_011Ceb2jXkW8aJKgqka1axbt` (2026-08-31T15:03:58.926Z)

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

### Block message
> API Error: Opus 4.8's safeguards flagged this message. Our intentionally broad safeguards allow us to deliver more capabilities faster, but can sometimes flag legitimate cybersecurity work.
