Delegated authority is the assignment that lets an AI agent act on an originator’s behalf. It sets the agent’s delegated scope: the work it may undertake and the constraints attached to that work. The originator may be a person, service account, workload or another agent.
Handing work to an agent doesn’t hand over the originator’s permissions, and it doesn’t authorize every operation the agent might attempt. Runtime policy evaluates each sensitive request using the identities involved, the delegation, the purpose, the tool, the target resource and current conditions. Connected controls then activate any access the task requires and enforce the decision.
Key takeaways
- Delegation defines what an agent may undertake on another identity’s behalf and within which constraints.
- Delegated scope, available permissions and current authorization are related but distinct.
- A workflow may draw on permissions held by the originator, the agent, service accounts or downstream tools. None of those permissions, on their own, establish that an action is authorized.
- Bounded delegation defines the task, resources, permitted actions, duration and limits on further delegation.
- Multi-agent workflows must preserve every participating agent and the delegation relationships between them.
- Enforcement and evidence are what show that actions stayed within the authorized scope.
Why does delegated authority matter?
An agent can receive a narrow assignment while holding credentials that allow far broader operations. A support employee might ask for one customer’s order history while the agent’s service account can read the entire customer database.
The delegation says what the agent may undertake. Existing permissions say what the workflow can technically reach. Runtime authorization decides whether a particular action is permitted under current policy and context.
Keeping those three ideas separate helps address three recurring access-control failures.
Incorrect attribution
A target-system log may name the service account that performed an operation without identifying the originator or the agents involved. Trusted identity and delegation records can tie that operation back to the task behind it.
That evidence doesn’t appear on its own because work was delegated. The workflow needs records that preserve the relationships and can be correlated with the observed action.
Rogue actions
An agent may have tools or permissions that are inappropriate for a particular user or task. A tool meant for account maintenance might also support bulk exports or destructive changes.
The risk is access that exceeds what the current request is permitted to do. Policy needs originator, delegation and task context to tell appropriate actions from those outside that scope.
Standing privileges and static credentials
Long-lived credentials can leave sensitive permissions available between tasks. Task-scoped access reduces that exposure when provisioning and revocation controls support it.
A bounded delegation doesn’t remove standing privilege by itself. The workflow still has to establish the right access scope and verify how that access ends.
Delegated authority, available permissions and current authorization
Three questions separate the concepts.
| Concept | Question it answers | Example |
| Delegated authority (delegated scope) | What may the agent undertake on the originator’s behalf, and within which constraints? | Retrieve the order history needed to resolve one customer’s support ticket |
| Available permissions | What operations can the identities and credentials technically perform? | The agent’s service account can read many customer accounts |
| Current authorization | Is this requested action permitted for these identities, this task and these conditions? | Policy allows the requested customer lookup and denies unrelated account queries |
Sometimes an agent needs access it doesn’t already have. Policy can authorize narrowly scoped access, which supported access-management controls then create or activate. The decision doesn’t have to be limited to permissions the originator and agent already share.
The reverse also holds. Holding a credential that permits an operation doesn’t place that operation inside the delegated task.
Where does delegated authority come from?
It starts with an assignment to act on another identity’s behalf. A person can assign work to an agent, a service can start an automated task or an orchestrator agent can hand off a subtask.
The assignment should state the purpose and the constraints the agent works within. A request on its own doesn’t override organizational policy, and it doesn’t establish that the originator is allowed to delegate that work.
Delegation and access sources are different
The credentials used to carry out a task can come from several places.
| Access source | Role in the workflow | What policy still needs to establish |
| Delegated user access | An application or agent uses access granted on a user’s behalf | Whether the requested action fits the task and applicable constraints |
| Agent identity | The agent has its own identity and assigned permissions | Whether those permissions may be exercised for this request |
| Service account | An automated component accesses a target through a service identity | Which task and participants are behind the operation |
| Tool or integration credential | A downstream tool uses its own credential to reach a resource | Whether the downstream operation stays within the authorized scope |
| Task-specific access | Supported controls activate temporary, scoped permissions | Whether the scope is enforced and access ends when required |
These sources often coexist. A developer can start a coding task, an agent can call a repository integration and a pipeline can run under a deployment service account.
That chain of events doesn’t mean the developer handed every downstream permission to the agent. The authorization model has to account for the access path the work actually takes and constrain how it is used.
How does delegation pass between agents and systems?
A delegation happens when one participant assigns work to another on its behalf, with a purpose and scope attached. An orchestrator agent might hand a record lookup to a sub-agent while it coordinates the wider workflow.
Other steps are technical execution. Calling a tool, forwarding a request or exchanging a credential doesn’t necessarily create a new delegation or transfer permissions.
Both kinds of step matter. Trace the workflow from the originator through participating agents and delegation to the tool, target resource, requested action and outcome, and preserve enough context to show who assigned the work, who executed it and which credentials reached the target.
In multi-agent workflows, each subtask should stay connected to the original purpose and its constraints. A new agent or credential must not quietly expand the authorized scope; broader work needs its own evaluation under policy and any approval requirements.
The originator isn’t always a person. A scheduled job may launch an orchestrator that delegates to a sub-agent, and the evidence should trace the action to that workload instead of assuming a human started it.
What keeps delegation bounded?
Bounded delegation spells out what the agent may undertake and the limits it works within.
| Boundary | What to define | Example |
| Task | Approved purpose or subtask | Retrieve the order history needed to resolve a support ticket |
| Resource | Systems, records or fields in scope | The customer account associated with that ticket |
| Action | Permitted operations | Read order history; deny bulk export and account deletion |
| Time and task state | Conditions under which the delegation and access remain valid | The task closes or its authorization expires |
| Further delegation | Whether another agent may receive work and under which constraints | A sub-agent may retrieve designated records without expanding the task |
Each boundary has to connect to a control that can enforce it. A task identifier in a request doesn’t restrict which records a downstream service account can read.
Evaluate each sensitive request
When a sensitive action is attempted, runtime authorization evaluates the identities, delegation, purpose, tool, target resource, requested action and current conditions against policy.
The decision may allow the action, limit it, require review, deny it or direct access to end. Human review happens when policy calls for it; routine actions that satisfy policy can proceed automatically.
For the underlying mechanics, see how runtime authorization works within runtime access control for AI agents.
Connect the decision to access and enforcement
An authorization decision determines what should be permitted. Where supported, access-management controls create or activate the permissions it requires.
Action-level enforcement governs the requested operation along a protected path. Where native target-system enforcement is supported, the target authorizes the action through its own access controls using the resulting identity and scoped permissions.
Enforcement sits outside the agent’s decision logic. However the agent interprets its task, that interpretation is no substitute for authorization.
Verify how access ends
Decide whether ending access means blocking further requests, removing target-system permissions, invalidating credentials or terminating sessions. Each has different effects and different support limitations.
After the task ends, test the access paths, credentials and sessions in scope. A successful revocation request doesn’t prove that every remaining path is unusable or that an operation already underway has stopped.
Task-scoped access can support Zero Standing Privilege when the controls keep sensitive privileges from staying available outside their justified use.
How delegated authority relates to blended identity context
Delegation describes what a participant may undertake on another identity’s behalf and the constraints attached to that assignment. Blended identity context preserves the identities and facts needed to evaluate the requests that follow.
P0 Security’s blended identity context keeps the originator, every participating agent and the delegation distinguishable through evaluation and enforcement, without copying or intersecting their permissions. In supported systems, that context can also shape the ephemeral target identity and task-scoped permissions.
All of this sits within the broader runtime access control for AI agents model: context informs authorization, connected controls enforce permitted access and evidence records what happened.
Bounded delegation vs. copying existing permissions
Copying existing permissions can expose access that has nothing to do with the task. Delegated workflows can use scoped grants, temporary credentials and runtime checks, but the implementation decides which safeguards actually apply.
| Dimension | Bounded delegation | Copying an existing permission set without task constraints |
| Starting point | An assignment to act on another identity’s behalf within defined limits | Permissions already available to another identity |
| Access selection | Access justified for the task under policy | Access carried over regardless of task relevance |
| Further delegation | Explicit constraints on assigned subtasks | Downstream delegation limits may remain undefined |
| Lifetime | Defined end conditions connected to lifecycle controls | Depends on the copied grant, credential and surrounding controls |
| Enforcement | Controls must apply the authorized scope | Copied permissions alone provide no task-specific restriction |
| Evidence | Records must connect delegation, decision, enforcement and outcome | Permission copying alone does not establish that traceability |
Bounded delegation is a design requirement. No token or task description supplies it for you; it has to be implemented and tested.
Examples of delegation in AI agent workflows
These examples show the intended policy and control behavior. They don’t describe support for particular product integrations.
Coding agent acting for a developer
A developer asks an agent to fix a failing test in one repository.
The delegated task allows changes to a feature branch. Policy requires review before anything merges to the main branch and denies production deployment for this task. The developer’s own production privileges don’t become part of the agent’s delegated scope.
If the agent hands test analysis to a sub-agent, that subtask stays tied to the same repository, task and restrictions.
Orchestrator delegating to a sub-agent
A scheduled reconciliation job launches an orchestrator agent, which assigns a data lookup to a sub-agent.
The workload that started the job remains the originator. The context also keeps the orchestrator, the sub-agent, the purpose of the lookup and its constraints.
The sub-agent’s request for designated records is evaluated within that scope. A request to export an unrelated data set gets its own evaluation and is denied if policy doesn’t permit it.
How P0 Security keeps delegation bounded
The P0 Runtime Access platform provides runtime access control across agents, users and machines. For agent workflows, P0 Runtime Access for AI evaluates each sensitive request with the originator, participating agents, delegation and task in view. Where native target-system enforcement is supported, P0 maps the session to ephemeral identities and task-scoped permissions so the target authorizes the action through its own controls, and removes that access when the task ends. P0 works alongside existing identity and access management (IAM) and privileged access management (PAM) systems. Supported workflows, integrations and deployment options vary.
P0 does not evaluate whether a prompt is malicious, whether model output is safe or how sensitive data should be classified. P0 determines whether the identities involved are authorized to take the requested action and enforces that decision before the action reaches the sensitive resource.
Frequently asked questions
Does delegated authority give the agent the user’s permissions?
No. Delegating work does not automatically copy permissions. The workflow may use delegated user access, agent permissions, service-account access or temporary grants, but policy still needs to determine whether the requested action is authorized for the task.
How is delegated authority different from delegated access?
Delegated authority refers to the assignment itself: what an agent may undertake on another identity’s behalf and within which constraints. Delegated access describes access to resources provided through delegation.
An agent can receive an assignment without receiving the originator’s credentials or permission set. Access needed to carry out that assignment must still be authorized and enforced.
How does delegated authority relate to OAuth scopes?
OAuth scopes express access ranges defined by the authorization server. They can be broad or narrow. Scopes alone may not express the task, participating agents, delegation relationships and current resource context needed for a particular agent workflow.
OAuth-based access can contribute to the design. Runtime policy and enforcement must still address requirements that the token and scopes do not establish.
Is every tool call a new delegation?
No. A tool call may execute part of an already delegated task. Assigning a subtask to another agent is a delegation event; forwarding a request or using a downstream credential is not necessarily one.
The workflow should preserve both delegation relationships and technical execution paths.
What happens when the delegated task ends?
The delegation should no longer justify further actions, and task-specific access should end according to policy. Depending on supported controls, that may involve removing permissions, invalidating credentials, ending sessions or blocking further protected requests.
Verify the actual result, including residual access and operations already underway.
Summary
Delegation defines what an agent may undertake on an originator’s behalf, with limits on purpose, resources, actions, duration and further delegation. It is separate from the permissions available through a user, agent, service account or tool credential.
Runtime authorization evaluates each sensitive request in context. Access-management and enforcement controls carry out the decision, and evidence records who delegated, which agents took part, what was permitted and what happened.
