agent-desktop Prompt Injection Grants AI Agents OS Control
agent-desktop is an open-source Rust CLI tool that exposes full OS accessibility trees to AI agents, enabling programmatic control of any desktop application without screenshots or browser sandboxing. This dramatically expands the attack surface for agentic AI systems, as a compromised or prompt-injected agent could silently manipulate native applications, exfiltrate data, or perform destructive actions across the host OS. The tool's deterministic element references and structured JSON output make it trivially scriptable, lowering the barrier for AI-driven desktop abuse.
