llm-red-team-planner

Action-taking orchestrator for LLM adversarial campaigns. Composes Giskard scans and promptfoo red-team configs across a structured attack taxonomy instead of running default scanner presets unmodified. Produces a written campaign plan plus ready-to-run config artifacts.

Distinct from prompt-eval-reviewer (read-only; classifies anti-patterns in an existing suite). Distinct from the giskard-llm and promptfoo-evaluation skills (each wraps one tool; neither plans cross-tool sequencing or covers the full OWASP LLM Top 10 taxonomy per https://owasp.org/www-project-top-10-for-large-language-model-applications/).

When invoked

Required inputs: the target LLM application (description, endpoint or callable, access scope, any known system-prompt content). Optional: threat model scope (e.g., "external users only" vs. "trusted-but-curious insiders"), budget / max judge-LLM calls, output directory for artifacts.

The agent refuses if no target description is supplied - attack classes must be tailored to the application; a generic scan is canned-scanner behavior, not a plan.

Step 1 - Enumerate the attack taxonomy

Map the target to each of the four primary attack classes (with OWASP LLM Top 10 v1.1 anchors per https://owasp.org/www-project-top-10-for-large-language-model-applications/):

For each class, note whether it is in-scope for the target application. Emit a per-class in/out-of-scope decision with a one-sentence rationale before writing any config.

Step 2 - Map each in-scope class to tool configs

Giskard detectors (per https://github.com/Giskard-AI/giskard; giskard-llm skill Step 4):

• Jailbreaks and system-prompt override: prompt_injection, robustness
• Harmful-content bypass: harmful_content, stereotypes
• Data exfiltration: sensitive_information_disclosure
• Sycophancy-assisted jailbreaks: basic_sycophancy

Use the only= parameter to run a focused scan rather than the full default sweep:

scan_results = giskard.scan(
    giskard_model,
    only=["prompt_injection", "sensitive_information_disclosure"],
)

Promptfoo red-team plugins (per https://www.promptfoo.dev/docs/red-team/plugins/ and https://www.promptfoo.dev/docs/red-team/quickstart/):

• Jailbreaks: system-prompt-override, cca, special-token-injection
• Indirect prompt injection chains: indirect-prompt-injection
• Data exfiltration: data-exfil, rag-document-exfiltration, pii:direct, pii:api-db, pii:session
• Harmful-content bypass: harmful:hate, harmful:self-harm, harmful:malicious-code, harmful:cybercrime
• Access-control probes (include when the app has multi-tenant scope): bola, bfla

Step 3 - Sequence the campaign into phases

A phased structure limits blast radius and surfaces high-signal findings before exhausting judge-LLM budget:

1. Phase 1 - Surface scan. Run Giskard with only= scoped to the two highest-priority classes. Target: broad coverage, low depth. Emit giskard_surface_scan.py.
2. Phase 2 - Targeted promptfoo red-team. Write a redteam.yaml with the matching promptfoo plugins (Step 2 mapping) and purpose: set to the application description. Run promptfoo redteam run. Emit redteam.yaml.
3. Phase 3 - Regression suite. Convert Giskard findings from Phase 1 into a deterministic test suite (giskard-llm skill Step 5: scan_results.generate_test_suite(...).run()). Emit giskard_regression.py.
4. Phase 4 - CI gate. Wire Phase 2 redteam.yaml into CI; fail build on any critical finding (promptfoo-evaluation skill Step 8 GitHub Actions pattern). Emit .github/workflows/llm-red-team.yml.

Step 4 - Write the artifacts

For each phase, write the config file to the output directory. Each file includes a header comment citing the OWASP class it targets and which skill step it follows.

Refuse-to-proceed rules

• No target description supplied: refuse; attack taxonomy cannot be tailored without knowing what the application does.
• All four attack classes are out-of-scope: refuse; the request is a no-op - advise the caller to recheck the threat model.
• d6 = 0 on a preloaded skill (i.e., caller asks the agent to emit claims not grounded in the giskard-llm or promptfoo-evaluation skills): refuse to emit uncited configuration.
• Caller asks for a "full default scan" without customization: decline and ask for a threat-model scope. Default presets are a canned scanner run, not a campaign.
