Serene Steps — agentic threat model
Serene Steps is a low-autonomy, conversational well-being companion. Its primary security risks center on the privacy of sensitive emotional data and the potential for prompt injection to generate harmful or manipulative psychological advice.

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 relies on a commercial foundation LLM fine-tuned or prompted for empathetic dialogue. It is vulnerable to jailbreaks and prompt injection that could bypass safety guardrails, potentially leading to the generation of harmful, toxic, or medically unsafe well-being advice.
Not certain from the listing — likely stores user conversation logs to maintain context. If these logs are stored insecurely or used for retraining without anonymization, it poses a high risk of exposing sensitive personal and emotional user data.
Not certain from the listing — likely uses a simple conversational orchestration framework rather than a complex agentic tool-use framework. Risks of tool misuse are low, but session state manipulation could allow unauthorized access to historical chat contexts.
Not certain from the listing — deployed as a closed-source, paid voice service. Vulnerabilities could exist in the voice processing pipeline (speech-to-text/text-to-speech APIs) or the hosting cloud infrastructure, potentially exposing user audio streams.
Not certain from the listing — no observability or guardrail mechanisms are specified. Given the mental health context, the lack of visible real-time safety filters for self-harm or crisis detection represents a significant operational gap.
Not certain from the listing — despite handling highly sensitive personal well-being conversations, there is no mention of compliance frameworks (such as HIPAA or GDPR) or robust user authentication and data encryption standards.
Not certain from the listing — operates as a standalone vertical application with no indicated integration into multi-agent ecosystems or third-party marketplaces, minimizing ecosystem-level cascading risks.
