Synthetic Scenario Generator

Software componentObservability & EvaluationObservability & Evaluationarc:SyntheticScenarioGenerator

An evaluation-data component that uses an LLM to generate diverse test scenarios within expert-defined database schemas and policy documents.

Responsibility. Generates diverse synthetic evaluation scenarios constrained by domain structure.

Also known as: LLM-guided scenario generation

Design guidance

SHOULD avoid deterministic templates so agents cannot succeed by pattern matching.
SHOULD validate that synthetic evaluation yields conclusions similar to evaluation on real data.

Classification

Patterns: Hybrid expert-structure plus generative synthesis
Technologies: GPT-4tau-bench
Quality attributes: Functional suitability: correctness and validity (ISO/IEC 25010 | NIST AI RMF: valid)
Risks mitigated: Template artifacts agents can memorizePrivacy-restricted real data
