Thesis
Technical guides, architecture and operational references for Hermes Shield.
Overview
Prompt injection is not just a prompt problem. It is an action-control problem. The model can fail. The action must not.
Hermes Shield sits between the agent and the world. The interesting question is never what the model said — it is what the system was about to do. Control the action and a compromised model becomes a contained failure instead of a live incident.
