Abstract:

   The Agent Action Decision Protocol (AADP) separates per-action
   authorization from an agent's identity and its standing capabilities,
   and gives that authorization semantics that a stateless tool
   permission or access grant cannot express: whether a specific
   proposed action, with specific argument values, may be performed now,
   given mutable state such as cumulative budgets, live reservations,
   approval lifecycle, and a kill switch.  Existing agent-security work
   concentrates on identity -- who an agent is, what credentials it
   holds, and which tools it may reach; AADP addresses the complementary
   decision, and composes with that work rather than replacing it.  This
   document defines a two-phase wire contract between a Policy Decision
   Point (PDP) that authorizes agent actions and the Policy Enforcement
   Points (PEPs) that perform them: verdicts with machine-readable
   reasons, obligations that fail closed, atomic budget reservation, an
   approval lifecycle, idempotency behavior, evidence sufficient to re-
   derive every verdict, and a set of evaluation invariants any
   conformant decision point must observe -- including the rule that an
   irreversible action is never executed autonomously.  The protocol is
   transport-agnostic and is designed so that decision points and
   enforcement points can be implemented independently, in different
   languages, by different parties.
