SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires @ai-sdk/anthropic, @langwatch/scenario, yaml, ai.

What problem does it solve?

Evals provides a structured framework to evaluate AI agents across complex workflows by uniting deterministic code-based checks, model-based rubrics, and human review into a single, repeatable process.

Core Features & Use Cases

  • Deterministic codified graders for fast, repeatable checks
  • Model-based rubrics for nuanced evaluation of outputs
  • Workflow orchestration for RunEval, CompareModels, ComparePrompts, CreateJudge, CreateUseCase, RunScenario, CreateScenario, ViewResults
  • Scenario-driven multi-turn evaluation with transcripts and tool-calls
  • Saturation and regression monitoring to guide suite maturation

Use cases: Benchmark agent behavior across coding, conversational, research, and GUI domains; compare models and prompts; build custom judges and evaluation pipelines.

Quick Start

Run a single evaluation to bootstrap a basic use case with prompts, test cases, and rubrics.

FAQPage Schema
How do I evaluate AI agent workflows with deterministic graders and model-based rubrics?

Evaluating AI agent workflows involves combining fast deterministic graders, nuanced model-based rubrics, and human review into a single repeatable pipeline. This validates agent behavior across coding, conversational, research, and GUI domains.

What is the best way to compare prompts and models for AI regression testing?

Comparing prompts and models for regression testing requires orchestrated workflows like ComparePrompts and CompareModels. These generate transcripts, tool-call tracking, and saturation analysis to establish reliable quality gates.

Does the AI evaluation pipeline support scenario-driven multi-turn conversations?

Yes, scenario-driven multi-turn evaluation is supported through CreateScenario and RunScenario workflows. They generate detailed transcripts and track tool-calls to benchmark agent behavior across complex conversational flows.

Can I use custom judges for nuanced evaluation of AI outputs?

Yes, you can build custom judges using the CreateJudge workflow. This allows you to define model-based rubrics for nuanced evaluation of AI outputs within your specific coding, research, or GUI domain.

How do I bootstrap a basic AI evaluation use case with test cases and rubrics?

Bootstrapping a basic use case requires running a single evaluation via RunEval. This quickly sets up your prompts, test cases, and rubrics to validate your AI agent workflow.
