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`
Output is nondeterministic and exact-match keeps flaking	Nondeterminism Strategies
AI states facts / cites sources / runs over RAG	Hallucination & Grounding
Pre-launch jailbreak, injection, PII, system-prompt leak	AI Safety Testing → `references/tooling-evals.md`
An AGENT (test harness, coding agent) reads tool output / RAG / scan reports / logs	Agent-as-Target Injection → `references/injection-detector.md`
