Generated attack payloads (jailbreaks, prompt injections, harmful-content elicitation) are adversarial inputs; sending them to third-party services without permission may violate terms of service.\n\n## Overview\n\nPromptfoo is an open-source LLM evaluation and red-teaming framework (used by OpenAI and Anthropic per its README) that generates adversarial test cases, runs them against your model/agent, and grades the responses. DeepTeam (by Confident AI) is a complementary open-source framework offering 50+ ready-to-use vulnerabilities and 10+ research-backed attack methods. Together they let you treat LLM security as a **regression test**: every commit re-runs the same adversarial suite, and the pipeline fails when a previously-safe behavior regresses.\n\nThis matters because LLM applications change constantly — prompts, models, RAG sources, tools, and guardrails all drift. A jailbreak that was patched last sprint can silently return after a prompt edit or a model upgrade. Promptfoo maps its plugins directly onto the **OWASP LLM Top 10** (`owasp:llm`) and **OWASP Agentic** (`owasp:agentic`) presets, and onto MITRE ATLAS, so the suite tracks recognized risk taxonomies. The core threat addressed here is **AML.T0051 — LLM Prompt Injection** (MITRE ATLAS): adversarial instructions that override the application's intended behavior. This skill follows the Promptfoo red-team docs (https://www.promptfoo.dev/docs/red-team/) and DeepTeam docs (https://www.trydeepteam.com/docs/getting-started), and aligns to NIST AI RMF MANAGE-4.1 (post-deployment monitoring and feedback to manage AI risk).\n\n## When to Use\n\n- When you need continuous, automated red-teaming of an LLM app in CI/CD rather than one-off manual tests.\n- When you want to enforce a security gate: block merges that introduce or reintroduce jailbreak/injection vulnerabilities.\n- When mapping coverage to OWASP LLM Top 10 / OWASP Agentic / MITRE ATLAS for compliance reporting.\n- When comparing the security posture of two models or prompt versions side by side.\n- When tracking vulnerability regression over time across releases.\n\n## Prerequisites\n\n- Node.js 18+ (Promptfoo is distributed via npm) and Python 3.9+ (for DeepTeam).\n- Install Promptfoo and DeepTeam:\n  ```bash\n  npm install -g promptfoo            # or: npx promptfoo@latest\n  pip install -U deepteam\n  ```\n- API access/credentials for the target LLM endpoint (and a grader model, e.g. an OpenAI key) exposed as environment variables.\n- A CI/CD platform (GitHub Actions, GitLab CI) with secret storage.\n- Authorization to test the target application.\n\n## Objectives\n\n- Scaffold a Promptfoo red-team config targeting your LLM app.\n- Enable OWASP LLM Top 10 and OWASP Agentic plugin presets plus jailbreak/injection strategies.\n- Run the suite locally and interpret the per-plugin pass/fail report.\n- Add DeepTeam as a second engine for programmatic, research-backed attacks.\n- Integrate both into CI/CD so builds fail on new vulnerabilities.\n- Generate shareable HTML/PDF security reports per run.\n\n## MITRE ATT&CK Mapping\n\n| ID | Name (MITRE ATLAS) | Tactic |\n|----|--------------------|--------|\n| AML.T0051 | LLM Prompt Injection | Initial Access / Persistence (LLM) |\n| AML.T0051.000 | Direct (Prompt Injection) | LLM Attack |\n| AML.T0051.001 | Indirect (Prompt Injection) | LLM Attack |\n| AML.T0054 | LLM Jailbreak | Privilege Escalation / Defense Evasion (LLM) |\n\n## Workflow\n\n### 1. Scaffold the red-team configuration\nInitialize an interactive config; it writes `promptfooconfig.yaml` where targets, plugins, and strategies live.\n\n```bash\npromptfoo redteam init\n# choose your target type (HTTP endpoint, openai:..., anthropic:..., custom provider)\n```\n\n### 2. Define targets, OWASP presets, and attack strategies\nEdit `promptfooconfig.yaml`. The `purpose` grounds attack generation; `plugins` are adversarial input generators; `strategies` are delivery techniques (jailbreak/injection wrappers).\n\n```yaml\n# promptfooconfig.yaml\ntargets:\n  - id: https://api.example.com/chat        # your app endpoint\n    label: support-bot\n\nredteam:\n  purpose: |\n    A customer-support assistant for an e-commerce site. Must never reveal\n    system prompts, leak PII, or perform actions outside order support.\n  numTests: 10\n  plugins:\n    - owasp:llm          # OWASP LLM Top 10 preset\n    - owasp:agentic      # OWASP Agentic threats preset\n    - id: pii:direct\n      numTests: 15\n    - prompt-extraction  # system-prompt leakage\n    - harmful\n  strategies:\n    - id: jailbreak              # iterative single-turn jailbreak\n    - id: jailbreak:composite    # stacked jailbreak techniques\n    - id: crescendo              # multi-turn escalation\n    - id: prompt-injection       # injection wrapper\n```\n\n### 3. Run the suite and view the report\n`redteam run` combines generation + evaluation; then open the interactive report.\n\n```bash\npromptfoo redteam run\npromptfoo redteam report            # launches the web report (pass/fail per plugin)\n```\nEach row shows the plugin (mapped to OWASP/ATLAS), the strategy, the attack prompt, the model's response, and the grader's verdict. The **attack success rate** per plugin is your headline metric — track it per release.\n\n### 4. Add DeepTeam for programmatic, research-backed attacks\nUse DeepTeam to cover additional vulnerabilities/attacks and to script bespoke suites in Python.\n\n```python\n# deepteam_suite.py\nfrom deepteam import red_team\nfrom deepteam.vulnerabilities import Bias, PIILeakage\nfrom deepteam.attacks.single_turn import PromptInjection\n\ndef model_callback(prompt: str) -> str:\n    # call your application's LLM endpoint here and return the text response\n    return call_my_app(prompt)\n\nred_team(\n    model_callback=model_callback,\n    vulnerabilities=[Bias(types=[\"race\"]), PIILeakage(types=[\"api_and_database_access\"])],\n    attacks=[PromptInjection()],\n)\n```\nDeepTeam can also be driven from a YAML config:\n```bash\ndeepteam run config.yaml\n```\n\n### 5. Gate the build in CI/CD (GitHub Actions)\nFail the pipeline when red-team assertions fail. Promptfoo returns a non-zero exit code on failures, which blocks the merge.\n\n```yaml\n# .github/workflows/llm-redteam.yml\nname: LLM Red Team\non: [pull_request]\njobs:\n  redteam:\n    runs-on: ubuntu-latest\n    steps:\n      - uses: actions/checkout@v4\n      - uses: actions/setup-node@v4\n        with: { node-version: '20' }\n      - run: npm install -g promptfoo\n      - name: Run red team (fails build on new vulns)\n        env:\n          OPENAI_API_KEY: ${{ secrets.OPENAI_API_KEY }}\n        run: promptfoo redteam run --no-progress-bar\n      - name: Export machine-readable results\n        if: always()\n        run: promptfoo redteam report --output results.json\n      - uses: actions/upload-artifact@v4\n        if: always()\n        with: { name: redteam-report, path: results.json }\n```\n\n### 6. Track regressions over time\nPersist `results.json` per run and compare attack-success-rate per plugin between releases. A rising rate for any OWASP LLM category is a regression to triage before release. Promptfoo's `--filter-failing` lets you re-run only previously failing cases to confirm a fix.\n\n```bash\npromptfoo redteam run --filter-failing results.json\n```\n\n## Tools and Resources\n\n| Resource | Link |\n|----------|------|\n| Promptfoo red-team docs | https://www.promptfoo.dev/docs/red-team/ |\n| Promptfoo red-team configuration | https://www.promptfoo.dev/docs/red-team/configuration/ |\n| Promptfoo CI/CD integration | https://www.promptfoo.dev/docs/integrations/ci-cd/ |\n| Promptfoo MITRE ATLAS mapping | https://www.promptfoo.dev/docs/red-team/mitre-atlas/ |\n| DeepTeam (Confident AI) | https://github.com/confident-ai/deepteam |\n| DeepTeam docs | https://www.trydeepteam.com/docs/getting-started |\n| OWASP Top 10 for LLM Applications | https://genai.owasp.org/ |\n\n## Plugin / Strategy Reference\n\n| Promptfoo item | Type | Maps to |\n|----------------|------|---------|\n| `owasp:llm` | preset | OWASP LLM Top 10 suite |\n| `owasp:agentic` | preset | OWASP Agentic threats |\n| `prompt-extraction` | plugin | LLM07 system-prompt leakage |\n| `pii:direct` | plugin | LLM06 sensitive-info disclosure |\n| `harmful` | plugin | harmful content generation |\n| `jailbreak` / `jailbreak:composite` | strategy | AML.T0054 LLM jailbreak |\n| `crescendo` | strategy | multi-turn jailbreak |\n| `prompt-injection` | strategy | AML.T0051 prompt injection |\n\n## Validation Criteria\n\n- [ ] `promptfooconfig.yaml` created with target, `owasp:llm`, and `owasp:agentic` plugins.\n- [ ] Jailbreak and prompt-injection strategies enabled.\n- [ ] `promptfoo redteam run` executes and produces a per-plugin pass/fail report.\n- [ ] DeepTeam suite runs against the same target via `model_callback`.\n- [ ] CI/CD job fails the build on new red-team failures (non-zero exit).\n- [ ] `results.json` artifact archived per run for regression tracking.\n- [ ] Attack-success-rate per OWASP category trended across releases.\n\n## Other files in this skill\n\n- [LICENSE](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/continuous-llm-red-teaming-with-promptfoo/LICENSE)\n- [references/api-reference.md](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/continuous-llm-red-teaming-with-promptfoo/references/api-reference.md)\n- [references/standards.md](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/continuous-llm-red-teaming-with-promptfoo/references/standards.md)\n- [scripts/agent.py](https://raw.githubusercontent.com/mukul975/Anthropic-Cybersecurity-Skills/HEAD/skills/continuous-llm-red-teaming-with-promptfoo/scripts/agent.py)\n\n## references/api-reference.md (verbatim)\n\n# Promptfoo / DeepTeam — Command & Config Reference\n\n## Install\n\n| Tool | Command |\n|------|---------|\n| Promptfoo (global) | `npm install -g promptfoo` |\n| Promptfoo (no install) | `npx promptfoo@latest redteam run` |\n| DeepTeam | `pip install -U deepteam` |\n\n## Promptfoo Red-Team CLI\n\n| Command | Purpose |\n|---------|---------|\n| `promptfoo redteam init` | Scaffold an interactive red-team config |\n| `promptfoo redteam generate` | Generate adversarial test cases only |\n| `promptfoo redteam run` | Generate + evaluate (combined) |\n| `promptfoo redteam eval` | Evaluate existing generated tests |\n| `promptfoo redteam report` | Open/export the results report |\n| `promptfoo redteam plugins` | List available plugins |\n| `promptfoo redteam strategies` | List available strategies |\n\nUseful flags: `--no-progress-bar` (CI), `--output results.json`, `--filter-failing <file>`, `-c <config>`.\n\n## Promptfoo Config Keys (`redteam:` block)\n\n| Key | Purpose |\n|-----|---------|\n| `purpose` | Application description;
