frontend-design — agentic threat model
This agent operates as a design-steering plugin for Claude Code, presenting low direct autonomy but posing indirect risks of generating malicious or vulnerable frontend code (e.g., XSS, CSS injection) if compromised or manipulated via prompt injection.

Scored with the canonical OWASP AIVSS formula (AIVSS calculator reference); agentic risk factors estimated from the agent’s described capabilities.
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 — relies on Anthropic's underlying Claude models. Primary threats include adversarial prompt injection that could bypass design constraints to generate malicious scripts or exfiltrate data via CSS injection.
Not certain from the listing — does not explicitly mention vector databases or RAG operations. It likely operates directly on the active codebase context provided by the developer.
Integrates directly with Claude Code and Composio. The bundled 'skills/commands' present a risk of tool misuse or command injection if the framework does not strictly validate the parameters passed to the code-generation engine.
Not certain from the listing — deployment is client-side within the developer's local environment where Claude Code runs. Threats include local directory traversal or unauthorized file modification if the plugin's execution environment is not sandboxed.
Not certain from the listing — there is no mention of real-time logging, output verification, or design-safety guardrails to detect if the plugin has been manipulated into generating malicious payloads.
Not certain from the listing — while open source and officially authored by Anthropic, there are no explicit details regarding compliance audits, static analysis of the plugin code, or formal security certifications.
Distributed via the Anthropic marketplace and Composio. This introduces supply chain risks, where a compromised update to the plugin could distribute malicious code-generation templates to a wide base of developers.
