before-you-build — agentic threat model
The agent acts as a local planning-stage gate within Claude Code, presenting low direct operational risk but high supply-chain risk; a compromise of this open-source plugin could allow arbitrary command execution on a developer's workstation.

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 Anthropic's Claude models via the Claude Code CLI. Primary threats include prompt injection that could manipulate the risk assessment or bypass the planning gate entirely.
Not certain from the listing — likely accesses local repository files and developer inputs to analyze product assumptions. Risks include exposure to malicious codebase files designed to poison the risk review process.
As a Claude Code plugin, it orchestrates custom commands and sub-agents. Vulnerabilities in how these commands are parsed or how the sub-agents are orchestrated could lead to insecure tool execution or logic bypasses.
Not certain from the listing — likely runs locally within the user's terminal as part of Claude Code. If the host environment is not sandboxed, a compromised plugin could achieve local code execution on the developer's machine.
Not certain from the listing — no built-in evaluation, guardrails, or logging mechanisms are described. This creates a blind spot where manipulated or bypassed risk reviews go undetected.
Not certain from the listing — as a free, open-source plugin, it likely lacks formal compliance certifications (e.g., SOC2) and relies entirely on the user's local security controls and policy enforcement.
The plugin explicitly introduces multiple 'agents' to interrogate assumptions. This multi-agent setup is vulnerable to trust abuse, where one sub-agent is manipulated to falsely validate a risky or malicious plan.
