ARTE — agentic threat model
ARTE is a low-risk, information-retrieval agent focused on tax research, presenting minimal direct operational risk but carrying potential financial and legal liabilities if poisoned data or hallucinations lead to incorrect tax filings.

MAESTRO 7-layer threat model
Per-layer threats for this agent. Layers tagged “not certain from listing” are general, caveated commentary where the public description didn’t pin that layer.
Not certain from the listing — likely utilizes a commercial or open-source LLM fine-tuned or prompted for tax accounting. Primary threats include adversarial prompt injection to bypass tax guardrails or generate fraudulent financial advice.
Highly critical layer as ARTE relies on a RAG pipeline with over 8,000 tax documents. Threats include knowledge-base poisoning (injecting incorrect tax codes or malicious advice into the vector store) and data exfiltration of sensitive user tax scenarios.
Not certain from the listing — likely uses a standard orchestration framework (e.g., LangChain) to manage the RAG query flow. Threats include insecure tool integration if the document retriever can be manipulated via prompt injection.
Not certain from the listing — hosted by Deferred.com or self-hosted (given its open-source tag). Threats include standard web application vulnerabilities, insecure API endpoints, and lack of sandboxing for user-uploaded documents if supported.
Not certain from the listing — while it has been evaluated against the CPA exam, there is no mention of real-time observability, drift detection for changing tax laws, or hallucination guardrails.
Not certain from the listing — no compliance certifications (e.g., SOC2) or specific data privacy controls (e.g., GDPR/CCPA for financial data) are mentioned, which is critical given the sensitive nature of tax inquiries.
ARTE operates as a standalone research assistant with no multi-agent coordination or marketplace integrations described, making ecosystem-level threats (like cascading agent failures) negligible.
