ARK runtime supervisor intercepts LangGraph agent tool calls
Aromatic-Ad-6711 · reddit · 2026-08-29
The author built ARK, a runtime supervision layer for tool-calling AI agents. It wraps the runtime to intercept non-compliant operations without taking control of the agent. In a test with LangGraph, ARK successfully blocked a flight booking (option A) that violated policy, forcing the model to replan and execute a compliant option (B). ARK also supports an observe-only mode for telemetry. The author is fixing a model-pricing resolution bug found during live testing before the SDK release.
