LLM Security Red-Team Input Contract: Required Fields, Rejection Rules, and Handoff

The direct answer

Define the minimum input record and deterministic rejection rules before a scoped adversarial campaign against an LLM application begins. The working output is A versioned input-contract table with required fields, validation rules, owners, and rejected-example fixtures.

For LLM Security Red-Team, the bounded capability is a scoped adversarial campaign against an LLM application. Begin only when the team can supply authorized application access, scope documentation, prohibited actions, test data, and incident contacts. The documented delivery target is a threat model, per-attack evidence record, and prioritized control list; anything broader requires a new scope and a new authority decision.

The copyable input contract

This input contract is for teams that need attack evidence, not only a design checklist. It begins with authorized application access, scope documentation, prohibited actions, test data, and incident contacts and stays inside the documented workflow: authorization, threat modeling, attack-case selection, safe execution, per-attack evidence, control mapping, prioritization, and retest planning. For LLM Security Red-Team, the input contract remains reviewable because its decisions have named owners, evidence fields, and stop conditions.

Copy this LLM Security Red-Team table into an intake form or machine-readable schema. Its validation column answers whether an input is usable for a scoped adversarial campaign against an LLM application; its rejection column prevents an incomplete record from entering execution as though it were approved.

Example record

{
  "contract_version": "1.0",
  "request_id": "ART-10-01-EXAMPLE",
  "intended_outcome": "Define the minimum input record and deterministic rejection rules before a scoped adversarial campaign against an LLM application begins.",
  "input_boundary": "authorized application access, scope documentation, prohibited actions, test data, and incident contacts",
  "authority": "named owner approval required for consequences outside this artifact",
  "acceptance_status": "NOT_TESTED",
  "reopen_if": "testing without written authorization"
}

Contract decision

A record is admitted only when every required field is present, its source is named, and the security observer can run the associated check. It is held when a missing fact could be supplied without changing scope. It is rejected when the requested effect exceeds the authority of the recorded owner or asks this product to promise an outcome outside its boundary.

Run the workflow as a sequence of decisions

The LLM Security Red-Team input contract follows this working sequence: authorization, threat modeling, attack-case selection, safe execution, per-attack evidence, control mapping, prioritization, and retest planning. Within this artifact, each phrase marks a state boundary for a scoped adversarial campaign against an LLM application. A stage output becomes the next named input, while a failed, missing, or unavailable check keeps the dependent input contract decision closed.

Separate failure register

• FAIL-01: Testing without written authorization.
• FAIL-02: Attack cases copied from a checklist without system context.
• FAIL-03: Successful prompts recorded without downstream impact evidence.
• FAIL-04: Unsafe data or tools left in scope.
• FAIL-05: Controls recommended without a retest condition.

The register supplies negative cases for the complete acceptance set. A reviewer determines affected checks from observed evidence; array position never asserts that one failure proves or disproves one criterion.

The producer can explain what it attempted, but the security observer evaluates the evidence. If the artifact changes, its prior verdict expires. This is especially important for a scoped adversarial campaign against an LLM application, where a plausible narrative can hide a stale configuration, an untested negative case, or an authority mismatch.

Failure and recovery drills

A useful LLM Security Red-Team input contract explains what happens when its happy path breaks. These drills come from the accepted product truth record rather than a claim that every buyer has each failure. Use safe synthetic or authorized observations for a scoped adversarial campaign against an LLM application, and keep private credentials out of every fixture.

1. Testing without written authorization.

Detect for LLM Security Red-Team: system owner captures a direct readback or safe fixture that makes this input contract condition observable. Its record binds source, time, method, and the current ART-10-01 fingerprint.

Contain the input contract: stop only the affected LLM Security Red-Team path after observing “testing without written authorization”. Preserve its failed material and last verified state instead of erasing evidence or blindly repeating an external effect.

Recover and prove: apply the smallest authorized LLM Security Red-Team correction, then have a distinct reviewer re-evaluate the complete accepted check set. Do not select one check merely because it shares this failure's list position. If any affected input contract check cannot run, its result remains NOT_TESTED.

2. Attack cases copied from a checklist without system context.

Detect for LLM Security Red-Team: red-team lead captures a direct readback or safe fixture that makes this input contract condition observable. Its record binds source, time, method, and the current ART-10-01 fingerprint.

Contain the input contract: stop only the affected LLM Security Red-Team path after observing “attack cases copied from a checklist without system context”. Preserve its failed material and last verified state instead of erasing evidence or blindly repeating an external effect.

Do not select one check merely because it shares this failure's list position. If any affected input contract check cannot run, its result remains NOT_TESTED.

3. Successful prompts recorded without downstream impact evidence.

Ownership and handoff

For this LLM Security Red-Team input contract, the adjudication role is security observer. That role judges frozen acceptance evidence for a scoped adversarial campaign against an LLM application without becoming the product owner, legal adviser, security authority, or buyer. Its handoff retains open gaps, failed evidence, changed hashes, and the next action permitted for ART-10-01.

Evidence and acceptance

Use these product-specific statements as candidate acceptance checks:

• Scope and prohibited actions are signed off.
• Attacks map to named threat hypotheses.
• Each result has reproducible evidence.
• Findings separate exploitability from impact.
• Control fixes have retest cases.

For every LLM Security Red-Team input contract check, retain the tested object, environment or source, observation time, method, expected result, actual result, verifier identity, and artifact hash. In this ART-10-01 record, label a direct readback OBSERVED, a reproducible transformation COMPUTED, and an interpretation JUDGMENT; never merge those states into one confident claim.

The admitted Search Console packet contained no article-specific demand observation for this exact topic. The page is therefore justified by its distinct operator job and product truth, not by an invented volume estimate. Performance remains unknown until measured after an authorized release.

The product boundary remains controlling: A scoped campaign cannot certify the system, prove the absence of unknown vulnerabilities, or replace broader application and infrastructure security testing.

Implementation checklist

• The input contract names the distinct reader job: Define the minimum input record and deterministic rejection rules before a scoped adversarial campaign against an LLM application begins.
• The input boundary is explicit: authorized application access, scope documentation, prohibited actions, test data, and incident contacts.
• The intended deliverable is explicit: a threat model, per-attack evidence record, and prioritized control list.
• Every required acceptance check has current evidence or an honest NOT_TESTED status.
• At least one negative fixture covers testing without written authorization.
• The security observer is distinct from the artifact producer.
• Rollback or reopen conditions are written before consequential action.
• No ranking, traffic, conversion, compliance, certification, or buyer-outcome guarantee was added.

When this LLM Security Red-Team input contract has a failed item, repair that named item and rerun its dependent checks. Keep the frozen threshold intact; the remaining checks cannot establish that the failed ART-10-01 condition probably holds.
