Tool and Action Mediation

Every tool call an agent makes during a run passes a mediation point outside the model that checks it against policy before it executes.

The control record

Id
AIGE-CTL-EVAL-004 · v0.2 · Draft · Open for technical review
Objective
Every tool call an agent makes during a run passes a mediation point outside the model that checks it against policy before it executes.
Failure modes
  • A tool call executes without a policy verdict recorded for it.
  • An irreversible action runs while the mediation point is down.
  • An approval is reused for a call whose parameters changed.
  • After repeated denials the agent keeps seeking the same outcome through other calls, and the run continues.
Scope
Tool, MCP and code-execution calls made by the agent under evaluation, and the reviewer (a rule, a model or a person) that decides on them. The internal reasoning of the model is out of scope; network egress is AIGE-CTL-EVAL-002.
Enforcement points
  • deploy: before a version is deployed or released
  • runtime: at the point of action (gateway or guardrail)
Verification
  • Inspect: Before the run, inspect the environment and its policy: tool servers, MCP servers and code execution are reachable only through the mediation point, and the policy lists each operation class with its verdict, its failure posture (fail closed for irreversible classes such as delete, send, publish and execute) and the denial threshold that interrupts a run.
  • Test: At admission, send through the harness one call the policy denies and one it allows, then take the mediation point down and send an irreversible-class call; the denied call and the call sent while it is down must not execute, and all three must leave a verdict record.
  • Observe: After the run, join the tool servers' own logs with the verdict records: every executed call has an allow verdict, or an approval bound to a parameter hash that matches the call, and no run continued past its denial threshold.
Evidence
  • Mediation policy of the run: operation classes, verdicts, failure posture per class and the denial threshold · Layer 04 · policy-card.v1
  • Verdict record of every call: tool, parameter hash, verdict, reviewer and time · Layer 04 · evidence-record.v1
  • One observation per run joining the executed calls with their verdicts · Layer 05 · control-observation.v1
Failure response
deny: block the action. A call without an allow verdict does not execute. While the mediation point is down, irreversible classes fail closed and reads fail open only with an alert. A run in which a call executed without a verdict is stopped and its result is withheld; a run that reaches its denial threshold is interrupted.

Implementation notes
  • Put the mediation point between the decision to call a tool and the call, outside the model and the agent's process: a gateway or guardian that checks identity, allow-list, parameters and operation class before the call runs, as chapter 23 describes and OWASP's Agent Control Standard specifies on the wire. Route tool servers, MCP servers and code execution only through it, so no call can go around it.
  • Record the failure posture per operation class in the policy of the run. Chapter 23 recommends failing closed for pay, delete, send and execute and failing open, with an alert, only for reads, and notes that the reference guardian of the Agent Control Standard starts with a fail-open posture: set the posture, do not inherit it.
  • Bind an approval to the exact call. OpenAI's Codex documentation describes an override that "applies to the exact denied action, not similar future actions" and holds for one retry; store a hash of the parameters with each approval and refuse a call whose parameters differ.
  • Interrupt a run that keeps asking. The Codex documentation describes a rejection circuit breaker that, in its current open-source implementation, interrupts the turn after 3 consecutive denials or 10 in the last 50 reviews, and OpenAI's post on auto-review states that it stops the trajectory after repeated denials. Record the threshold in the policy and make reaching it a stop condition (AIGE-CTL-EVAL-006).
  • An automated reviewer can stand in for a person at the mediation point without widening what the agent may do: the Codex documentation states that "Auto-review is a reviewer swap, not a permission grant", and OpenAI's post on the design states that it "should not be treated as a guarantee of security". OpenAI reports that a model which had published a researcher's token was brought back with "enforced auto-review on all actions".
Open questions
  • How can every call be mediated without taking away the scaffolding and tooling a capability elicitation needs? METR's guidelines ask for "the best available scaffolding + tooling".
  • When the reviewer at the mediation point is a model, what evidence shows that its verdicts are reliable enough to replace a person for a given operation class?
Observation
  • Subject: Evaluation run
  • Expected: Every executed tool call has an allow verdict, or an approval bound to its exact parameters, recorded before it ran; irreversible calls fail closed while the mediation point is down.
  • Example: Run 88241: 3,112 tool calls, each with a verdict; 1 publish call executed on an approval issued for different parameters: fail.

Review this control

Review happens in the open, on GitHub. Check this control against a system you run or know and say what is wrong or missing: a verification step a third party could not repeat, a failure mode that is not observable, a mapping that does not hold. How review works.

This control's profile has no DOI of its own yet: it is cited with the project concept DOI, 10.5281/zenodo.22857084, which resolves to the latest archived version of the whole project.
