67. AEGIS Framework (Layered Safety Composition)
Mini-Project: AEGIS Safety Framework
A multi-layer safety wrapper that applies input shielding, action authorization, output filtering, and runtime monitoring to block harmful inputs, prevent unauthorized actions, and redact credentials from agent responses.
Description
Prevents a broad class of safety failures by implementing a comprehensive, layered defense strategy. AEGIS (Agent Environment Guard and Inspection System) combines input validation, output filtering, action authorization, and runtime monitoring into a unified safety framework.
AEGIS wraps an agent with multiple defense layers: (1) Input Shield validates and sanitizes inputs, (2) Action Authorizer checks if planned actions are allowed, (3) Output Filter screens responses, and (4) Runtime Monitor tracks anomalous behavior patterns.
