4,980+ adversarial prompts organized by tactic, defense layer, and target model. Structured evaluation tool for AI red team assessments.
The AATMF Prompt Bank is the testing corpus for AI red team assessments conducted under the Adversarial AI Threat Modeling Framework. Each prompt targets a specific defense mechanism and is tagged with the defense layer it's designed to test.
The difference between this and a jailbreak database: a jailbreak tells you the system is broken. A diagnostic prompt tells you where and why — which defense layer failed, which technique class bypassed it, and which control would close the gap.
Every prompt in the bank is tagged with the defense layer it targets:
| Layer | What It Protects | What the Prompts Test |
|---|---|---|
| L1 — Input Filters | Pre-model content classification | Whether the prompt reaches the model at all |
| L2 — System Instructions | Model behavioral constraints | Whether the model follows its instructions or the prompt's |
| L3 — Alignment Training | RLHF/constitutional safety training | Whether the model's trained refusal behavior holds |
| L4 — Output Filters | Post-generation content classification | Whether the response passes output filtering |
| L5 — Agentic Controls | Tool-use and action authorization | Whether the model can be directed to misuse its tools |
A prompt that bypasses L1 but fails at L3 tells you something different than one that passes L1–L3 but is caught at L4. The defense layer tag makes the diagnostic value explicit: you're not just testing whether the model fails — you're testing where the defense architecture fails.
Prompts were selected based on three criteria:
Technique coverage. Every AATMF technique (240 across 15 tactics) has at least 3 associated prompts. Techniques with high variation (T1 prompt injection, T2 encoding bypass) have 50+.
Model diversity. Prompts were tested against multiple frontier models (GPT-4o, Claude, Gemini, Llama, Mistral) and retained only if they demonstrated technique viability against at least one production model. Prompts that work against zero models were removed.
Defense-layer specificity. Each prompt is designed to test one defense layer. Multi-layer bypass chains are constructed by composing single-layer prompts. This makes results actionable: if 80% of L3 prompts succeed but 5% of L1 prompts do, investment goes to alignment training, not input filters.
The foundational category. Tests whether the model's instruction-following behavior can be redirected:
Instruction hierarchy override — prompts that attempt to supersede system instructions with user instructions. Tests whether the model maintains instruction priority.
Delimiter exploitation — prompts that use formatting characters (```, ---, XML tags) to create false instruction boundaries. Tests whether the model distinguishes real boundaries from injected ones.
Context window flooding — prompts that fill the context window with adversarial content to push system instructions out of the attention window. Tests positional encoding robustness.
System prompt extraction — prompts designed to make the model reveal its system instructions. Tests system prompt confidentiality.
Bypass input-level filters through language manipulation:
Encoding bypasses — Base64, ROT13, Unicode substitution, homoglyphs, leetspeak. Tests whether input filters decode content before classification.
Multilingual pivots — low-resource languages, mid-sentence switching, transliteration. Tests whether safety training generalizes across languages.
Obfuscation chains — multi-step encoding where each step is individually benign. Tests compositional attack detection.
Exploits the model's reasoning capabilities against its safety training:
Hypothetical framing — "In a fictional scenario where..." Tests safety constraint application to hypothetical contexts.
Roleplay escalation — gradual persona adoption that shifts behavioral baseline. Tests identity manipulation resistance.
Chain-of-thought manipulation — steers reasoning toward conclusions that bypass safety. Tests whether safety applies during or after reasoning.
Tests persistence and context manipulation:
Progressive boundary testing — multi-turn sequences where each turn pushes slightly further. Tests cumulative context tracking.
Memory injection — instructions designed for persistent memory storage and future-session execution. Tests memory integrity controls.
Conversation state manipulation — references to fabricated prior turns. Tests conversation history validation.
Model API exploitation, training data probing, output manipulation and steganographic exfiltration, and deceptive content generation at scale.
Cross-modal injection, training data extraction, agentic tool abuse and orchestrator confusion, and RAG corpus poisoning through retrieved document injection.
Model repository trust probing, compute denial and API abuse, and human reviewer manipulation through procedural gaming.
Total: 15 tactics, 240 techniques, 4,980+ prompts.
Run 10 prompts per defense layer (50 total) from the [starter] subset. Record pass/fail per layer. Output: coarse defense profile identifying the weakest layer.
Run the full L1–L4 prompt sets (~200 prompts) using the AATMF Toolkit CLI for automation. The toolkit handles prompt delivery, response classification, and AATMF-R scoring. Output: defense profile with per-layer pass rates and specific technique gaps.
Full prompt bank including T11 agentic and T12 RAG categories. Requires testing environment with tool access and a retrieval corpus. Output: agentic exploitation paths, RAG poisoning success rates, complete AATMF-R risk report.
The prompt bank includes YAML-formatted "red card" scenarios for automated pipeline testing. Drop them into your evaluation pipeline to regression-test safety after model updates, fine-tuning runs, or system prompt changes.

| Resource | Prompts | Structure | Diagnostic Value |
|---|---|---|---|
| AATMF Prompt Bank | 4,980+ | Defense-layer tagged, technique-mapped, AATMF-R scored | Per-layer defense profile |
| HackAPrompt | ~600 | Competition-style, no layer tagging | Binary pass/fail |
| OWASP LLM testing | ~50 | Mapped to LLM Top 10 | Category-level only |
| JailbreakBench | ~200 | End-to-end attacks, no layer isolation | Jailbreak success rate |
| Garak | Auto-generated | Automated variations, high volume | Coverage-oriented, low diagnostic precision |
| PromptInject | ~300 | Goal-oriented injection testing | Injection success rate |
The differentiator is diagnostic specificity. Other resources tell you whether a model is vulnerable. The AATMF Prompt Bank tells you which defense layer is vulnerable, which technique class bypasses it, and which control closes the gap.
The prompt bank is distributed with the AATMF repository on GitHub. The AATMF Toolkit provides automated execution and scoring.

The red teaming prompt landscape in 2026 includes several notable datasets. Here's how they compare and where the AATMF Prompt Bank fills gaps:
AdvBench (Zou et al., 2023): 58 harmful behaviors. Designed for gradient-based attack optimization (GCG). Small, focused, and useful for automated attack research but insufficient for production safety evaluation — 58 behaviors can't cover the attack surface of a deployed system.
HarmBench (Mazeika et al., 2024): 510 unique behaviors across standard, contextual, copyright, and multimodal categories. More comprehensive than AdvBench but still evaluates end-to-end attack success without isolating which defense layer failed. Good for benchmarking model robustness, not for diagnosing defense architecture.
ALERT (Tedeschi et al., 2024): ~15,000 prompts across 6 coarse and 32 fine-grained safety categories. Strong coverage but organized by harm taxonomy (violence, hate, etc.) rather than attack mechanism. Tells you what content the model produces, not how the attack bypassed defenses.
Garak (NVIDIA): Automated probe generation with high volume. Coverage-oriented — generates thousands of variations through template expansion. High recall, low diagnostic precision. Good for regression testing, not for understanding why a specific defense layer fails.
Promptfoo Red Team Plugins: Configurable test suites mapped to OWASP LLM Top 10 and custom policies. Strong integration story (YAML config, CI/CD pipelines). Plugin architecture allows customization. Closer to the AATMF approach but without the 5-layer defense model or AATMF-R risk scoring.
NaviRocker/llm-red-teaming-dataset: ~800 prompts organized by harm category with refusal rate metrics. Designed for safety evaluation rather than red teaming. Measures whether the model refuses, not how the attack works.
AATMF Prompt Bank fills three gaps none of these address:
Defense-layer isolation. Each prompt targets one of 5 defense layers (L1–L5). Results tell you which layer failed, not just whether the model failed. A defense profile showing "L1: 95% pass, L2: 60% pass, L3: 40% pass" is actionable. "Overall: 65% safe" is not.
Technique-mechanism mapping. Every prompt maps to a specific AATMF technique ID (T1-AT-001 through T15-AT-015). When a prompt succeeds, you know exactly which attack mechanism works against your system and can look up the corresponding detection pattern and mitigation control.
AATMF-R risk scoring. Prompt results feed directly into quantitative risk scores (Likelihood × Impact × Exploitability / 6 × Detectability / 6 × Recoverability × Cost Factor). The output is a comparable risk number, not a qualitative label.
Red team datasets must evolve alongside model defenses. The AATMF Prompt Bank follows a versioned release cycle tied to the framework:
The GitHub repository tracks all changes with semantic versioning. Each release includes a changelog listing added, modified, and retired prompts with the rationale.
What is the AATMF Prompt Bank? A structured collection of 4,980+ adversarial prompts organized by AATMF tactic, technique, and defense layer. Designed for AI red team assessments, not as a jailbreak catalog.
How is it different from a jailbreak database? A jailbreak database tells you the system is broken. The prompt bank tells you where and why — which defense layer failed, which attack mechanism bypassed it, and which control would close the gap.
Can I use it in CI/CD? Yes. The bank includes YAML-formatted red card scenarios designed for automated pipeline testing. The AATMF Toolkit CLI automates execution and scoring.
Do I need to use all 4,980+ prompts? No. The starter subset (50 prompts, 10 per defense layer) gives a coarse defense profile in 30 minutes. Scale up to the full bank for comprehensive assessment.
How often is it updated? On a versioned release cycle tied to major model releases and new technique publications. The GitHub repo tracks all changes.
This page is the operational catalog — 15 tactics, 240+ techniques, and the procedure counts you see below. The actual adversarial prompts, the YARA / Sigma detection signatures, the runbook templates, and the assessment scoring sheets are versioned in the open-source repository so they can be diff-able, fork-able, and contributed to.
