Agent Capability Analysis
The eval-harness skill by affaan-m is an open-source official AI agent skill for Claude Code and other IDE workflows, helping agents execute tasks with better context, repeatability, and domain-specific guidance. Optimized for ai-agents, anthropic, claude-code.
Ideal Agent Persona
Ideal for AI Agents like Claude Code, AutoGPT, and LangChain needing a formal evaluation framework for implementing eval-driven development principles
Core Value
Empowers agents to implement eval-driven development (EDD) principles, utilizing pass@k metrics for reliability measurement, and creating regression test suites for prompt or agent changes, all while ensuring continuous evaluation and tracking of regressions with each change using code-based, model-based, or human graders
↓ Capabilities Granted for eval-harness
! Prerequisites & Limits
- Requires definition of expected behavior and success criteria before implementation
