evals

Use when authoring evaluations with strands-agents-evals. Activates on tasks involving Case/Experiment construction, picking evaluators (Output, Trajectory, Helpfulness, Faithfulness, Coherence, Conciseness, ResponseRelevance, Harmfulness, Refusal, Stereotyping, InstructionFollowing, GoalSuccessRate, ToolSelection/ParameterAccuracy, Multimodal*), trace-based evaluation with mappers (CloudWatch, OpenSearch, OpenInference, LangChain OTel, Strands in-memory), simulators (ActorSimulator, ToolSimulator), failure detection and root-cause analysis (detect_failures, analyze_root_cause, diagnose_session), chaos / fault-injection testing (ChaosCase, ChaosExperiment, ChaosPlugin), red-team evaluation (RedTeamExperiment, AdversarialCaseGenerator, AttackSuccessEvaluator, attack strategies), or auto test-case generation (ExperimentGenerator). Trigger phrases include "evaluate this agent", "score the trajectory", "simulate a user", "diagnose the session", "generate test cases", "LLM-as-a-Judge", "inject tool failures", "cha
