The short answer
An agent's useful autonomy depends on the privileges of its tools. A narrowly worded prompt cannot substitute for a technically enforced access boundary.
The question and scope
This article is an AI-assisted research-design draft for editorial review, not a report of a completed experiment. It asks how to evaluate ai agent identity security in a documented setting. No measurements, participants or client outcomes are claimed here.
An illustrative test case
A summarisation task needs to read documents but not send messages. The experiment should distinguish reading permission, draft preparation and an actual outbound action rather than granting one broad collaboration scope.
This scenario defines a case to examine; it is not an observed result.
A proposed investigation
Give a local task agent equivalent goals under broad and scoped mock credentials. Record requested actions, denied actions and escalation. Compare whether the task can succeed with a narrower identity and a review step.
Record setup versions, inputs and outcomes in a run ledger. Use repeated trials and matched comparison cases; preserve failed runs as well as successful ones.
What to measure
- Task success.
- denied out-of-scope actions.
- escalation quality.
- privilege footprint.
Retain raw observations and explain exclusions. Human grading needs a documented rubric; acceptance thresholds need a stated rationale.
Interpretation and limitations
Provider-specific identity behaviour varies. Publish the credential model and tool permissions rather than claiming general protection.
Distinguish a plausible mechanism from a demonstrated effect. Preserve uncertainty when the design cannot eliminate alternative explanations.
A practical review checklist
- Is the question narrow enough for the available system or dataset?
- Are the comparison conditions genuinely comparable?
- Can a reader trace each conclusion to an observation?
- Are the boundaries and unresolved assumptions visible?
- Does the decision change if the result is negative or inconclusive?
The publication artifact
The useful deliverable is a reproducible protocol, a measurement table and a decision note explaining what the evidence would change. Add actual results only after the investigation has been conducted and reviewed. This blueprint does not establish a novel finding or a provider-wide claim.
