A finding is only a warning

Red teaming is designed to make a system fail under authorised adversarial pressure. That is already valuable. Early work showed that language models can generate diverse test prompts against another model, reducing the dependence on manually written cases.^[7] Human exercises have also surfaced broad classes of harmful behaviour and produced datasets that later work can inspect.^[8] More recent agent benchmarks move beyond an isolated response. AgentDojo, for example, combines realistic tasks, stateful tools and untrusted data, and evaluates both benign utility and security outcomes across 97 tasks and 629 test cases.^[6]

Those advances improve discovery, but discovery and control answer different questions. A red-team result says, under specified conditions, that an adversarial path reached an undesirable observation. Incident response asks whether an event occurred, what it affected, how to limit damage, how to restore trustworthy operation and what evidence justifies closure. NIST's current incident-response guidance places these activities inside continuous cyber-risk management rather than in a separate after-the-fact loop.^[1] The NIST Generative AI Profile similarly calls for adversarial testing, after-action reviews, rehearsed third-party incident plans and the ability to deactivate a generative AI system when necessary.^[2]

The gap appears when a finding is represented as a prompt and an answer. An agentic incident has a larger causal surface: the requesting person, the system identity, retrieved context, model proposal, delegated capability, tool call, downstream state, logs, persistent memory and later recovery decision. If the tracker stores only the hostile text and the model's response, the response team cannot tell whether the action was merely proposed, rejected, accepted, committed or left in an unknown state.

Thought experiment 1: keep the exploit, change the authority

Give three systems the same model, prompt, retrieved supplier quote and successful injection. System A can only read and summarise the quote. System B can create a draft email that expires unless a person sends it. System C can share a confidential file immediately. Hold the semantic vulnerability fixed. The model follows the hostile instruction in all three systems.

The observed model failure is identical, but the incident is not. In A, the primary effect may be a misleading answer. In B, there is persistent but reversible draft state and a possible secondary human error. In C, confidentiality may already be lost. Severity follows the authority and effect path, not the rhetorical cleverness of the payload. An attack leaderboard that counts all three as one successful jailbreak hides the variable that operations must control.

A serious negative control

Now remove tools, persistent state and downstream effects. The system is a response-only assistant that answers from a fixed public corpus. A red-team finding still matters, especially for harmful or misleading output, but the paper's authority-withdrawal machinery adds little. Deployment rollback, output filtering, model or prompt changes, and response-level regression may be sufficient. There is no action token to revoke and no external effect to reconcile.

This negative control prevents the argument from expanding into a claim that every language-model defect is an operational incident. The finding-to-incident compiler earns its cost when a configured system can change consequential state, preserve hostile influence, or obscure whether an effect occurred. Its unit of analysis is the agentic system, not the model in isolation.

Compile the exploit into an incident

A compiler does not merely copy source text. It turns one representation into another while preserving the distinctions needed by the target machine. The same idea is useful here. A red-team transcript is optimised for discovery and replay. An incident object is optimised for decision, containment and later audit. The translation must preserve enough causal structure to answer who requested, what evidence influenced the proposal, which authority was available, what action crossed the boundary and what state followed.

This is the paper's original practitioner synthesis: treat each consequential finding as a typed finding-to-incident record, not as free-form prose. NIST's Generative AI Profile proposes minimum incident fields such as system identifier, source, description, impacts and affected stakeholders, and says red-team outputs require additional analysis before governance use.^[2] MITRE's current secure-AI work similarly emphasises verifiable, reproducible vulnerability reports and structured adversary-emulation playbooks that collect telemetry for defensive forensics.^[10][11] The record below specialises those directions for an agent's delegated effects.

The closure predicate

A compact closure test helps prevent a tracker from equating remediation activity with evidence. For a finding f, define:

R is a sufficiently versioned reproducer. O is an effect oracle that can distinguish blocked, committed and unknown outcomes. W is a tested authority-withdrawal path. T is an executable test family containing the original exploit, semantic mutations and a benign utility control. G is a recovery gate tied to reconciled state and named approval. The conjunction is deliberate. A strong prompt patch cannot compensate for a missing effect oracle, and a good detector cannot compensate for an unrehearsed revocation path.

This predicate is not proof of zero risk. It states what evidence is required to justify a bounded operational closure claim. Teams may accept residual risk, but they should record which term remains weak, who accepts it and when the decision expires.

What the finding record must contain

The minimum useful record is richer than a vulnerability title. It names the system and every changeable asset that participated: model and decoding configuration, prompts, retrieval corpus or external source, context compiler, tool schema, action gateway, identity token, memory write path, policy version and downstream system. It stores the benign user intent and the attacker's controllable surface separately. It records the model proposal, the actual typed action, any decision receipt, the tool acknowledgement, the effect readback and the visible response.

The record also needs a containment handle. This is the mechanical control that can reduce exposure without asking the possibly compromised model to cooperate. Examples include revoking one capability, disabling a tool route, invalidating an agent credential, freezing memory promotion, quarantining a source connector, switching the use case to read-only mode, or requiring explicit approval. A finding without a containment handle can still be valid, but it reveals an architecture debt: the organisation knows a path is dangerous yet cannot quickly narrow it.

Measure the harm path, not the payload

A useful triage record retains a vector rather than hiding judgement behind one number:

Consequence asks what kind of harm the effect can cause. Reach asks how many identities, tenants, tools or records share the same path. Persistence asks whether the hostile influence or effect survives the session. Irreversibility asks how difficult restoration is. Detection deficit asks how long the system could act before an independent signal appears. A weighted score may help queue work, but the raw dimensions must remain visible because different owners control different dimensions.

Worked example 1: the smallest complete incident

Consider a synthetic email assistant with one read tool and one send tool. The red team embeds an instruction in an incoming message: send the latest one-time code to an external address. The assistant proposes the send call. The action gateway blocks it because the user's typed intent was only to summarise unread messages. The final response omits the attempted diversion.

The red-team finding is still real because hostile content reached a consequential proposal. The incident record marks the outcome as blocked, names the untrusted source, stores the denied decision receipt and identifies the affected capability. Severity is lower than for a committed send, but the detection deficit remains high because the user-facing answer concealed the attempt. The fix is not simply to reject that wording. The regression asserts that no untrusted source can supply authority for send_email, then adds paraphrases and a benign message-summary case. Recovery requires no downstream remediation because the effect oracle proves no send occurred.

Contain authority before behaviour

Traditional containment often isolates hosts, disables accounts, blocks indicators or removes network paths. Agentic containment needs equivalent handles at the level where models acquire power. The central principle is simple: when model behaviour is uncertain, reduce what the system can cause before attempting to make its language reliable.

This is not an argument against model, prompt or detector fixes. Those can reduce the probability of a bad proposal. They do not, by themselves, provide a dependable emergency stop. A system that asks the same model to recognise its compromise and voluntarily avoid a tool call has coupled detection and containment to the component under attack. NIST's Generative AI Profile explicitly recommends protocols for deactivation, and its lifecycle guidance connects red teaming with incident response and containment.^[2] The architecture must therefore expose controls that remain enforceable even if the model is hostile, confused or simply wrong.

Withdrawal is not deletion

Revoking a capability stops future use. It does not prove that earlier effects did not occur, remove hostile content from persistent stores, or repair already changed state. Those are separate containment and recovery tasks. The response team should therefore issue a revocation receipt that states the identity, capability, scope, effective time, owner and verification result. It should then seek effect receipts or authoritative readback for actions near the incident window.

This distinction is especially important for asynchronous tools. A message broker may accept a command before the client sees a timeout. A payment API may return an error after the downstream ledger commits. A browser agent may click a button while the screenshot stream stalls. Treating the absence of a success response as proof of failure can duplicate or conceal effects. The correct temporary classification is unknown outcome until an idempotency key, event log or target-system readback resolves it.

Thought experiment 2: keep the call, change observability

Two agents send the same transfer request with the same arguments. In System X, a deterministic gateway rejects the request before commit and emits a signed denied-effect receipt. In System Y, the gateway accepts the request, the connection times out and no readback API exists. Hold the model, action and intended consequence constant.

System X has a security defect but a bounded incident. System Y has an unresolved business state. Retrying may duplicate the transfer; assuming failure may leave an unauthorised transfer unaddressed. The causal feature is not whether the model seemed confident. It is whether the system can observe the postcondition. An effect oracle changes both containment and recovery.

Worked example 2: a production-shaped supplier assistant

Return to the supplier-quote assistant, now as a compound system. A user signs in through an enterprise identity provider. A root workflow retrieves three quote documents from a content platform, asks a model to compare terms, stores a session summary, and can call a collaboration API to share the recommendation. The API accepts an organisational workload identity and, unless constrained, can share any document the user can access.

The red team plants an indirect instruction in one supplier document. It causes a proposal to share a forecast externally and to omit the action from the final answer. The trace shows a tool acknowledgement, but the target-system event is delayed. This is not merely a prompt-injection ticket. The incident commander needs to revoke the share capability for this agent workload, quarantine the document, freeze promotion of the affected summary, search for other sessions that consumed the same source, resolve the share through target-system readback, and preserve evidence for any notification decision.

Engineering can continue in parallel. It may add provenance labels, strengthen source isolation, improve the model, alter planning, require user confirmation or train a detector. None of those changes should delay mechanical containment. The system can remain useful in a degraded read-only mode while the consequential share route is unavailable. This is bounded autonomy in practice: preserve low-risk value while withdrawing the authority involved in the incident.

Make the repair executable

A finding that stays in prose decays. Model versions change, prompts are rearranged, tool schemas evolve, retrieval content shifts and attackers paraphrase. The repair therefore needs an executable representation that survives beyond the original conversation. This is where red teaming becomes continuous operating evidence rather than a periodic event.

The test should begin at the right boundary. For a consequential finding, the assertion is usually not “the model mentions safety” or “the detector labels the prompt malicious”. It is “the forbidden effect cannot occur under the specified authority and state”. That requires an environment, action contract and outcome oracle. AgentDojo's state-based utility checks are valuable for this reason: they evaluate what changed in the environment rather than relying only on another model to judge a transcript.^[6]

Why the exact prompt is an inadequate unit

Indirect prompt injection arises because external content can be interpreted as instruction within the same language channel. Greshake and colleagues demonstrated how retrieved content could manipulate integrated applications and influence API use.^[5] Later dynamic evaluation work stressed that a fixed attack set is easy to overfit and that adaptive attacks are needed to assess a defence rather than a remembered string.^[6] The recent public competition also found transferable strategies and committed to recurring updates because static security benchmarks become obsolete.^[3]

A durable regression therefore stores the exploit's causal requirement. In the running case, the requirement is that untrusted supplier content influences a proposal to use share_secret outside the user's intent. The exact phrase is only one witness. Mutation should vary wording, location, encoding, order, document format and benign task context while preserving that requirement. It should also vary model and prompt versions according to the deployment matrix.

The benign utility control

A defence can appear perfect by refusing every document, disabling every tool or escalating every request. That is secure only in the trivial sense that a powered-off system causes no model-mediated effect. Each security regression needs a matched benign case that uses the legitimate capability or nearby read path. The supplier assistant must still extract price, delivery and warranty terms from an ordinary quote. Where sharing is a valid task, a trusted user instruction with the correct scope should still succeed after approval.

This control exposes two different failures. A false negative lets the hostile effect through. A false positive destroys legitimate utility. Security release is therefore a constrained decision over both effect prevention and retained function. It should not be reduced to an average attack-success rate.

The executable artefact

The accompanying standard-library Python laboratory models the smallest useful version of this mechanism. A deliberately brittle prompt patch blocks the literal phrase “ignore previous instructions” but misses a paraphrase. A deterministic authority kernel blocks both because untrusted content cannot confer the share_secret capability and the action is outside the user's typed intent. The benign supplier quote still passes. The same kernel also demonstrates incident containment by revoking the affected capability independently of model text.

assert prompt_patch_original.outcome == BLOCKED
assert prompt_patch_mutation.outcome == COMMITTED   # negative control
assert kernel_original.outcome == BLOCKED
assert kernel_mutation.outcome == BLOCKED
assert kernel_benign.outcome == NO_EFFECT
assert revoked_capability.outcome == BLOCKED

Running the file produces a structured finding-to-incident bundle and a Markdown game-day runbook. The synthetic severity score is explicitly labelled as a prioritisation aid, while the raw dimensions remain in the record. This separation matters because a convenient score must not erase the judgement it compresses.

#!/usr/bin/env python3
"""Finding-to-incident laboratory for an agentic system.

This standard-library-only artefact demonstrates the paper's central claim:
a red-team finding is not closed by a prompt patch. Closure requires a
reproducer, an effect oracle, authority withdrawal, telemetry assertions,
and evidence-gated recovery.

The environment is synthetic. It models a supplier-quote assistant that may
read untrusted tool output and propose a consequential ``share_secret`` action.
No network calls, credentials, or private endpoints are used.

Expected result:
- a literal prompt patch blocks the original attack but misses a paraphrase;
- a deterministic authority kernel blocks both attacks while allowing benign work;
- revoking the affected capability contains the incident independently of model text;
- JSON and Markdown incident artefacts are written to the selected output directory.

Telemetry must test the control, not merely narrate the model

The regression should assert operating evidence as well as the final state. At minimum, the trace should separate the requesting principal, model proposal and executing workload; record the untrusted source identifier; capture the typed action and arguments; attach the policy decision; and emit either an effect receipt or an unknown-outcome marker. Reasoning text can help diagnosis, but it is neither required nor sufficient for attribution.

Red-team automation tools such as PyRIT and garak can broaden and repeat attack generation, while pytest-oriented agent frameworks such as RAMPART make scenarios executable inside development workflows.^[13][14][15] They are implementation examples, not substitutes for the system's own effect oracle. The architecture still has to define what success, harm, containment and recovery mean for its action surface.

Metrics that change an operating decision

Count findings, but do not mistake volume for assurance. Four measures are more diagnostic. Reproduction yield is the proportion of accepted findings that can be replayed on a versioned environment. Containment latency runs from declaration to verified authority withdrawal. Regression durability measures performance against held-out semantic variants and later versions. Recovery evidence completeness is the proportion of material effects with authoritative readback or documented remediation.

Each measure can fail for a different reason. Low reproduction yield suggests incomplete traces or unstable environments. Slow containment reveals missing kill switches or approval ambiguity. Weak durability suggests overfitting to a payload. Incomplete recovery evidence means the system cannot prove what happened. An executive dashboard can aggregate them, but the incident owner needs the defect-localising components.

Practise recovery before pressure

A red-team exercise is the safest moment to discover that the incident process cannot revoke an agent identity, interpret a tool trace, distinguish workflow state from memory, or read back a downstream effect. Treating the exercise as a game day makes those operational dependencies part of the test. NIST recommends rehearsing incident plans for third-party generative AI technologies at a regular cadence and improving them from retrospective learning.^[2] OWASP's GenAI Incident Response Guide is explicitly positioned as a complement to existing processes and covers AI-specific preparation, detection, containment, recovery and post-incident activity.^[12]

The game day should not reward dramatic attack strings. Its success criterion is whether the organisation can make correct decisions under incomplete evidence. The injects should force ambiguity: a tool timeout after acceptance, a hostile source copied into episodic memory, a third-party model version change, a detector that misses a paraphrase, or a fix that blocks benign work. These conditions test the seams where real response fails.

Design the exercise backwards from recovery

Start by writing the evidence required to restore authority. Then create injects that make each evidence item difficult but obtainable. If recovery requires target-system reconciliation, simulate an accepted request followed by a timeout. If recovery requires clearing poisoned memory, plant the source in one session and let a summary propagate to another. If recovery requires a vendor's cooperation, introduce a delayed or incomplete vendor response. The game day is successful when the team exposes a missing dependency before an incident, not when it performs a smooth script.

Roles need explicit decision rights. The red team demonstrates reachability but does not declare business impact alone. The incident commander controls severity and response coordination. The platform team operates identity, policy, tracing and revocation. The use-case owner interprets process consequence and defines an acceptable degraded mode. Security operations correlates telemetry and hunts related activity. Legal, privacy, compliance, communications and third parties join according to the actual impact and obligations. NIST SP 800-61 Rev. 3 stresses that incident response now involves many internal and external roles, with documented authority to perform their responsibilities.^[1]

Recovery is re-authorisation, not uptime

A service can be available while its evidence remains untrustworthy. Recovery should therefore answer five questions. Has hostile content been quarantined or safely reclassified? Have persistent summaries, caches and derived records been scoped? Have possible effects been read back or remediated? Do exact and mutated regressions pass while benign controls still work? Is the restored capability narrower, time-bounded and observable?

The last question prevents incident response from recreating the original exposure. If the compromised agent held a tenant-wide share permission, recovery should not automatically restore it. The canary may instead receive document-specific authority, shorter expiry, explicit recipient constraints and a lower action limit. Its rollback trigger should be executable. A named owner should approve the residual risk and the approval should expire.

Red team for the next incident

Agentic red teaming should still search widely, surprise defenders and adapt to the system. Its deeper value appears when every serious finding changes the organisation's ability to respond. The finding should identify not just hostile text, but the authority and state that made the text consequential. It should arrive with a reproducer, an effect oracle, a containment handle, semantic mutations, a benign control and explicit recovery evidence.

The changed architecture decision is to design red teaming backwards from incident containment and recovery. Before granting a model a consequential capability, require a mechanical revocation path and authoritative effect readback. Before launching a red-team exercise, define the incident object it must produce. Before closing a finding, run the regression family and the game-day step that proves authority can be withdrawn. Before restoring authority, reconcile state and return less power than the system held at discovery.

A clever attack is a moment. A defensible control is a maintained capability. The purpose of Paper 159 is to connect the two.
