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.
