Test AI/LLM features that ship in your product. Covers prompt regression testing, response quality evaluation, tool-call validation, hallucination and RAG grounding checks, nondeterministic-output strategies, red-team/safety scans, eval frameworks, and agent-as-target injection (indirect injection via tool output / RAG / scan reports, self-propagating payloads, data exfiltration via an agent) plus a bundled detector for untrusted content. Use when: "test our LLM feature…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
<objective> AI features fail differently from deterministic software. The same input produces different outputs, correctness is subjective, and failure modes include hallucination, prompt injection, and silent quality decay. A chatbot that confidently cites a fabricated URL passes every `toBeDefined()` check. This skill covers how to test AI features rigorously despite nondeterminism: versioned prompts, eval suites scored against golden datasets, statistical and property-based assertions, tool-call validation, grounding checks, and red-team safety scans. </objective> --- ## Quick Route | Situation | Go to | |-----------|-------| | Prompt changed, need to catch quality regressions | Prompt Regression Testing → `references/prompt-regression.md` | | Run the same prompt across providers/models and compare | Cross-Provider Regression → `references/tooling-evals.md` | | Score open-ended output (relevance/completeness/safety) | Response Quality Evaluation → `references/eval-framework.md` | | Agent calls tools/functions — verify selection and args | Tool-Call Validation → `references/tooling-evals.md` | …

How to install
mdr add petrkindlmann/qa-skills/ai-system-testing@sha256:3cdbccd0380f2387The line at the top of this page pins the label v2.2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
