From deb031f9ca3587dd1f2699fff64e4a90d0e2a79b Mon Sep 17 00:00:00 2001 From: Nathan Walston Date: Mon, 10 Aug 2026 14:29:30 -0700 Subject: [PATCH 1/4] feat(nemo-agents): add specialist subagents to the email-phishing example The orchestrator now fans out to specialist subagents before the verdict, so the analysis is a traced, tunable chain instead of one opaque classification: - url-brand-analyst - lookalike / brand-impersonation judgement on the domains extract_iocs harvested (tool -> subagent composition) - attack-attributor - names the attack category (bec/credential/malware/spam/benign) - header-auth-analyst - SPF/DKIM/DMARC reading, gated on the email actually carrying Authentication-Results:/Received: headers phishing-analyzer stays the verdict owner and folds the findings in, adding `attack_type` and `impersonated_brand` to the YAML verdict. Prompts are ported from the email-security-analyst NAT example (they were removed from it in #1135 as more protocol than that sample needed). There they were LLM capability tools behind a router; here each is a declarative subagent, so its reasoning gets its own trace span and its prompt is tunable in agent.yaml. The prompt-injection guardrails are ported with them. analyze_headers is demo-only: the scored dataset has no SMTP headers, and synthesizing them per row would leak the phishing/benign label into the input and inflate the eval. README shows a header-bearing email to exercise it by hand. Verified live (--mode subprocess, real NVIDIA_API_KEY): 3/3 invocations return the correct schema - phishing (plain + header-bearing) true, benign false - with attack_type and impersonated_brand populated. The runtime checkpointer shows all four subagent tasks plus the extract_iocs tool call. AgentConfig validate + Fabric translate OK; ruff clean; 8/8 tool tests.
