Could you build this?
Partial Creating a basic policy engine or JSON-schema validator for agent tool calls is easy, but robustly modeling side effects, safety invariants, and stateful multi-step agent validation requires formal verification or specialized security mechanics.
What it would actually take: The platform needs a proxy/middleware engine intercepting tool calls (like bash, SQL, or API calls) with symbolic execution or dynamic policy evaluation (e.g., using OPA/Rego or eBPF/container sandboxing). The challenging component is static and dynamic analysis to accurately predict side-effects of chained LLM tool actions before execution without introducing massive latency or false positives.

Same idea, different domain
Nobody's really built a agent / copilot tool for Agriculture yet.
