SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Evaluations are critical for robust AI development. This framework provides a structured approach to define, run, and report evals for Claude Code sessions, enabling consistent quality checks across models and prompts.

Core Features & Use Cases

  • Capability and Regression Evals definitions with reusable templates
  • Multi-grader support: code, model, and human evaluators
  • Metrics collection and reporting (pass@k, pass^k)
  • Integration with the /eval workflow and local storage under .claude/evals
  • Use Case: establish regression tests for agent behaviors and measure impact of updates

Quick Start

Define an eval with /eval, implement it, run /eval check, and generate a final evaluation report.

FAQPage Schema
How do I set up regression evals for AI agent behaviors?

Regression evals for AI agent behaviors are defined using the /eval command, implemented, checked with /eval check, and stored as runnable workflows under .claude/evals to measure the impact of updates.

What metrics are used for tracking AI evaluation reliability?

For tracking AI evaluation reliability, the framework collects pass@k and pass^k metrics across projects to enforce consistent quality checks across models and prompts.

What grader types are supported for AI evaluation workflows?

Supported grader types for AI evaluation workflows include code, model, and human evaluators, enabling consistent quality checks across different models and prompts.

Do I need external dependencies to run capability evaluations?

No external dependencies are required to run capability evaluations. The framework integrates directly with the /eval workflow and stores definitions, implementations, and reports locally under .claude/evals.

When do I need a formal evaluation framework for AI development?

A formal evaluation framework for AI development is needed when establishing regression tests for agent behaviors and measuring the impact of prompt or model updates across multiple projects.
