SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Defines a disciplined framework to evaluate LLM and agent outputs by establishing explicit specs, binary tests, and graded evaluation. It helps teams design clear evaluation rubrics, compare models, and align judgments across evaluators.

Core Features & Use Cases

  • Three-layer structure: Spec (upstream truth), Test Functions (pass/fail gates), and Evaluation Functions (quality scoring).
  • Supports calibration across multiple evaluators and iterative prompt/agent improvement.
  • Use cases include evaluating response quality, grading outputs, and benchmarking different agents or models.

Quick Start

Define your spec, derive tests from it, and apply evaluation functions to score outputs.

FAQPage Schema
How do I design an evaluation rubric for LLM and agent outputs?

To design an evaluation rubric for LLM and agent outputs, define an explicit three-layer structure: establish the upstream spec, derive binary test functions for pass/fail gating, and apply evaluation functions for graded quality scoring.

What is the best way to compare multiple AI models and calibrate judgments across evaluators?

The best way to compare multiple AI models and calibrate judgments across evaluators is to apply an anchored scoring scale within a structured spec-test-eval framework, ensuring consistent grading and clear pass/fail gating mechanisms.

How do I set up pass/fail gating mechanisms for evaluating AI responses?

Set up pass/fail gating mechanisms for evaluating AI responses by deriving binary test functions directly from your upstream spec, ensuring outputs meet explicit baseline requirements before undergoing graded quality scoring.

Can I use this three-layer framework to benchmark different agents iteratively?

Yes, you can use this three-layer framework to benchmark different agents iteratively. It supports calibrating judgments across multiple evaluators and refining prompts or agent logic by anchoring scores against a consistent spec.

Why do I need an upstream spec before writing test functions for AI evaluation?

You need an upstream spec before writing test functions for AI evaluation because the spec serves as the source of truth. Test functions and graded evaluation scales are derived directly from this spec to ensure disciplined, aligned judgments.
