Authorization
May this actor perform this action?
Reference notes by Min · Reviewed October 11, 2026
Definition
Authorization determines whether an identified actor may perform a particular action on a resource under applicable rules.
An authorization decision is specific to an actor, operation, resource and relevant context. Access to a tool does not necessarily authorize every parameter combination that tool accepts. A valid request can still need a narrower resource or task scope.
What it covers
- Action
- Read, write, export, send or execute.
- Resource
- The record, service or system affected.
- Context
- Task, requester, approval and current restrictions.
Define permissions at the meaningful operation boundary: reading one case, drafting a reply and committing a refund are different actions. Consider target ownership, tenant boundaries, task expiry and required approval when designing that decision.
In practice
Practical design patterns by Min.
- Evaluate permission at the tool boundary.
- Scope decisions to the actual resource and operation.
- Recheck after scope or authority changes.
Translate business authority into explicit service rules. Keep those rules outside model-generated text and apply them to the exact submitted parameters.
Evaluate negative cases such as another customer’s record, an expired task or a write operation requested through a read-only workflow. Retain the reason for denial without leaking protected data.
Working example
Reading is allowed; exporting is not
An agent can view an assigned support case.
- Authenticate the actor.
- Check the requested operation against case permissions.
- Deny a bulk export even if viewing one case is allowed.
Why the controls matter
The same authenticated support agent may read its assigned case while being denied another customer’s file. Both outcomes are consistent with one workload identity and different resource scopes.
Common pitfalls
- Using authentication as the entire access decision.
- Checking permission only when the task starts.
A successful check at the beginning of a long task may become stale. Identify actions that require a fresh decision when they are actually committed.
Questions for operational review
Use these questions to decide what evidence your team needs. They are editorial prompts, not a compliance checklist.
- What exact action is authorized?
- For which resource and requester?
- When must the decision be reevaluated?
