SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This skill provides a structured framework to measure agent performance and validate context engineering decisions, enabling teams to quantify quality, track improvements, and detect regressions.

Core Features & Use Cases

  • Multi-dimensional rubrics for factual accuracy, completeness, citation accuracy, source quality, and tool efficiency.
  • LLM-based judgment combined with human evaluation to scale validation across large test sets.
  • Design and manage test sets, evaluation pipelines, and continuous monitoring for production quality.
  • Production monitoring dashboards and alerting to surface quality issues in real time.

Quick Start

Prepare a task, expected ground truth, and an agent output, then run the evaluation to obtain an overall score and per-dimension scores.

FAQPage Schema
How do I measure agent performance with evaluation rubrics?

Evaluation rubrics define scoring dimensions like factual accuracy, completeness, and citation quality. Create structured rubrics that score each dimension, then apply them to agent outputs against ground truth to obtain per-dimension and overall performance scores.

What's the best way to design test sets for LLM agent evaluation?

Test-set design involves preparing tasks with expected ground-truth outputs and corresponding agent responses. Structure test sets to cover diverse scenarios, then run evaluations across the full set to identify performance patterns and regressions.

Can I use LLM-as-judge for scaling evaluation across large datasets?

LLM-based judgment combined with human evaluation scales validation across large test sets. LLMs score outputs against rubrics while humans validate critical or ambiguous cases, reducing manual effort while maintaining quality assurance.

How do I set up production monitoring to detect quality regressions?

Production monitoring uses dashboards and alerting to track agent performance metrics in real time. Continuous evaluation pipelines surface quality issues automatically, enabling rapid detection and response to performance drops.

What dimensions should I include when evaluating context-engineering outcomes?

Multi-dimensional rubrics assess factual accuracy, completeness, citation accuracy, source quality, and tool efficiency. These dimensions collectively measure whether context engineering decisions improve agent output quality and user trust.

Do I need ground truth data to run agent performance evaluation?

Yes, evaluation requires expected ground-truth outputs to compare against agent responses. Ground truth provides the benchmark for scoring each dimension, enabling objective measurement of agent performance and context-engineering decisions.
