From 4d55a7dcecc3ec2c835e5c9dac4a627084fd348a Mon Sep 17 00:00:00 2001 From: Adam Lin Date: Wed, 3 Jun 2026 04:36:21 +0800 Subject: [PATCH 1/5] FEAT add AgentThreatRulesScorer (ATR taxonomy scorer) Add a deterministic TrueFalseScorer that evaluates text against the open Agent Threat Rules (ATR) ruleset via the pyatr engine and returns True when a rule at or above a configurable min_severity matches, attaching matched rule ids / ATR category / max severity as score metadata. Mirrors SubStringScorer; pyatr (>=0.2.6) is an optional dependency.
