As agents take on consequential work — financial transactions, external communication, enterprise workflows — the question stops being whether a model can produce a good answer and becomes whether a particular action should be executed at all: on whose authority, and under what conditions.
Existing agent infrastructure authenticates workloads and controls resource access through identity federation and delegated authorization. That establishes whether an action is permitted in principle. It does not establish whether an authorised action should execute given the current behavioural and operational context.
AgentBound is a runtime governance framework that evaluates each proposed action against three independent authorities — delegated authorization, owner-signed behavioural constitutions, and site action contracts — and composes their judgments conservatively into a decision to permit, review, or deny before execution.
For accountability, it produces cryptographically verifiable governance receipts that bind an action to the exact delegation, policy, and semantic artifacts that governed it, so decisions can be independently replayed and verified. The paper also introduces standing delegation for long-running agents, and AgentBound-Bench, a benchmark for evaluating governance correctness, authority composition, and accountability.
AgentBound is not a substitute for model alignment. It is a deterministic layer between authorization and execution — an attempt to turn governance from something that must be trusted into something that can be checked.
