FAQPage Schema
What is eval-driven development for AI coding sessions?

Eval-driven development integrates formal evaluation frameworks directly into AI coding sessions to ensure reliability. It uses capability and regression evaluations alongside pass@k metrics to verify AI-assisted workflows meet defined criteria.

How do I create an evaluation for a Claude Code task?

To create an evaluation for a Claude Code task, use the /eval define command. This initiates the formal evaluation framework to assess your specific AI-driven development workflow.

What grading methods are available for AI code regression testing?

AI code regression testing supports code-based, model-based, and human graders. These grading methods assess capability and regression evaluations to measure workflow reliability using pass@k metrics.

Can I measure AI coding reliability using pass@k metrics in Claude Code?

Yes, you can measure AI coding reliability using pass@k metrics in Claude Code. The evaluation framework calculates these metrics to formally assess whether your AI-assisted workflows meet defined reliability criteria.

Does Claude Code evaluation support both capability and regression testing?

Yes, Claude Code evaluation supports both capability and regression testing. The framework handles both evaluation types to ensure your AI-assisted workflows maintain reliability and meet defined criteria across sessions.
