Your AI Agents Can Execute Every Tool Call Correctly and Still Break Every Enterprise Rule
VentureBeat, Monday, October 12th, 2026
Tool calling makes single actions deterministic but leaves the agent's decision layer probabilistic and the tool boundary ungoverned.
The author challenges the assumption that agents plus tools plus data deliver enterprise agility.
While tool calling makes each action deterministic, the agent still probabilistically decides which tool to call, when and with what arguments.
Because generic tools execute whatever they are handed, governance shifts to an exposed tool boundary.
In domains touching employees, customers and finance, the author argues there is zero tolerance for drift, so business rules must be enforced at the tool layer rather than trusted to the model.
