From model proxy to action control plane
Traditional gateways authenticate a request and forward it. Agentic systems need more context: who initiated the action, which workspace owns it, what data it carries and whether a tool is allowed to act on the requested resource.
That context must survive an entire workflow. Otherwise a safe first model call can still lead to an unsafe tool invocation three steps later.
Policy belongs in the path
Budgets, data classification, regional restrictions and human approval rules should be evaluated before a destination is invoked. The gateway becomes the enforcement point rather than another dashboard that explains a failure after it happened.
For operators, a unified trace connects model reasoning, memory retrieval and tool execution. For developers, the same trace makes complex multi-step failures debuggable.
Test the route before production
A gateway should include a playground where teams can simulate policy outcomes, inspect the selected path and export the exact integration code. Governance becomes understandable when the system shows its decision, not just its configuration.
