SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Eval Designer enables teams to design and implement robust evaluation frameworks for LLM systems to measure quality, safety, accuracy, and alignment across prompts, models, and deployments.

Core Features & Use Cases

  • Define evaluation goals and scope for end-to-end LLM evaluation.
  • Build test suites, rubrics, and automated evaluation pipelines; support human calibration and versioned runs.
  • Apply to CI/CD pipelines for model or prompt changes, safety audits, and regression testing.

Quick Start

Define an evaluation brief for a new LLM feature and generate an accompanying rubric and automated test plan.

Frequently Asked Questions about eval-designer

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I design an LLM evaluation rubric for safety and alignment?

Design an LLM evaluation rubric by defining scope for safety and alignment, generating test case categories, and establishing thresholds calibrated with human labels to measure system quality.

What is the best way to automate LLM evaluation pipelines in CI/CD?

Automate LLM evaluation pipelines in CI/CD by building test suites and rubrics that run automatically across model changes, capturing versioned run metadata to ensure reproducible safety and regression testing results.

How do I calibrate LLM evaluation thresholds with human labels?

Calibrate LLM evaluation thresholds with human labels by documenting versioned run metadata and comparing automated rubric scores against human-labeled test cases to ensure alignment and measurement accuracy.

Can I use automated evaluation pipelines for prompt regression testing?

You can use automated evaluation pipelines for prompt regression testing by applying defined rubrics and test case categories to CI/CD workflows, measuring safety and accuracy across prompt changes.

Why do I need versioned run metadata for LLM benchmarking?

Versioned run metadata is needed for LLM benchmarking to document thresholds, track calibration with human labels, and ensure reproducible results across model changes and safety scenarios.

What is an LLM evaluation brief and when do I need one?

An LLM evaluation brief defines evaluation goals and scope for measuring quality, safety, and accuracy, needed when building automated test plans and rubrics for new LLM features or deployments.
