SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill solves the problem of unreliable AI behavior by applying rigorous, test-driven discipline to probabilistic systems, ensuring that model-dependent features meet a measurable quality bar before deployment.

Core Features & Use Cases

  • Eval-Driven Development: Establishes a failing-test-first cycle for prompts and models, ensuring features are built to meet a specific threshold.
  • Independent Evaluation: Enforces the use of an independent judge model to prevent self-grading bias and ensure objective scoring.
  • Safety & Red-Teaming: Integrates adversarial testing and safety gates to prevent prompt injection and harmful outputs in production.

Quick Start

Use the evals skill to define a new evaluation plan for the current prompt by creating a dataset of inputs and a rubric for an independent judge model.

FAQPage Schema
What is eval-driven development for AI-native applications?

Eval-driven development applies test-driven discipline to probabilistic AI systems by establishing datasets, rubrics, and quality thresholds to ensure model-dependent features meet a measurable quality bar before deployment.

How do I prevent self-grading bias when testing prompt outputs?

To prevent self-grading bias during prompt testing, you must define an independent judge model to evaluate outputs against a rubric, ensuring objective scoring rather than allowing the target model to grade its own responses.

How do I integrate AI testing gates into a CI/CD pipeline?

You integrate AI testing gates into a CI/CD pipeline by defining evaluation datasets and quality thresholds that act as automated checkpoints, blocking deployment if probabilistic outputs or safety guardrails fail to meet the rubric.

Can I use red-teaming to prevent prompt injection in production?

Yes, you can prevent prompt injection and harmful outputs in production by integrating adversarial red-teaming tests as safety gates within your evaluation lifecycle, ensuring model features pass rigorous validation before release.

What do I need to set up an evaluation plan for a prompt?

To set up an evaluation plan for a prompt, you need to create a dataset of inputs, define a scoring rubric, and configure an independent judge model to evaluate the outputs against your established quality thresholds.
