AuctraAuthority & delegation foundations
Multi-agent delegation chains explained
When Agent A delegates to Agent B, permissions must narrow—not widen—and the full chain from human sponsor to sub-agent action must be reconstructable. How Auctra models delegation chains.

Why delegation chains matter
Multi-agent systems spread work across planners, executors, and specialists. Regulators and incident reviewers ask one question: who authorized this action at the root?
Delegation chains record the human sponsor, each delegating agent, narrowing scopes, and the evaluating agent at execution time. Without chains, accountability diffuses across hops.
Industry guidance—from IETF audit drafts to enterprise governance frameworks—converges on traceable provenance. Auctra preserves sponsor and delegator identity on every evaluateAction decision.
Rules that keep chains safe
Root human never disappears: every chain traces to a named sponsor registered on the originating agent or parent workflow.
Permissions only narrow: a sub-agent delegation must be a subset of its parent's grant—never broader API access or higher spending limits.
Expiration propagates: child delegations cannot outlive parent grants; renewal is a deliberate sponsor-visible event.
Cycles are blocked: agents must not delegate back to ancestors in ways that re-expand authority without human review.
What to log at every hop
Minimum evidence per hop: trace ID, parent agent, child agent, action type, active scope, evaluation outcome, and timestamp.
Auctra decision records capture agent, sponsor, delegation ID, structured intent, and allow/block/approve result—queryable without manual log stitching.
For deep hierarchies, cap maximum delegation depth and alert when chains exceed policy. Shallow, well-audited chains beat opaque orchestration graphs.
Deploy chain governance with Auctra
Register orchestrator and worker agents separately, each with sponsors. Issue parent delegations first; child grants only within parent limits.
Call evaluateAction at worker execution boundaries—even when the planner already evaluated—so the accountability record reflects the acting agent.
Business plan hash-chained audit supports auditor requests to reconstruct full chains within retention SLAs.
Key takeaways
- Multi-agent accountability requires chain instrumentation in real time—not post-hoc forensics.
- Narrowing permissions at each hop prevents privilege expansion through orchestration.
- evaluateAction at execution boundaries produces defensible provenance per acting agent.
Implementation checklist
- Document agent topology: orchestrators, workers, and human entry points.
- Register every production agent with a sponsor in Auctra.
- Enforce child delegations as subsets of parent grants.
- Evaluate at worker boundaries with shared trace IDs across hops.
- Set max delegation depth and alert on violations.
People also ask
- What is a delegation chain in AI agents?
- A recorded path from human sponsor through each delegating agent to the agent that executed an action, including scopes active at every hop.
- Should sub-agents inherit parent API keys?
- No—use scoped delegations and evaluateAction per acting agent. Standing credentials without delegation records break accountability.
- How deep should delegation chains go?
- Most teams cap at two to four hops with explicit policy; deeper chains require stronger automated narrowing and audit SLAs.
