SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

Brings rigor to prompt design by providing a framework for validating prompts with blank-slate subagents and automated CI regression, reducing bias and hidden errors in instruction.

Core Features & Use Cases

  • Empirical Subagent Validation: run prompts against blank-slate subagents to measure requirement achievement, enabling data-driven improvements.
  • Declarative CI Regression: set up a promptfoo pipeline that automatically evaluates prompt behavior against a matrix of tests.
  • Reusable guidance: apply to AGENTS.md, CLAUDE.md, and Wiki procedures for consistent prompt quality across teams.

Quick Start

Run the empirical validation workflow by configuring scenarios, dispatching blank-slate subagents, and reviewing results using the promptfoo CI pipeline.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I set up CI regression testing for prompt engineering?

You set up CI regression testing for prompt engineering by configuring a declarative promptfoo pipeline that automatically evaluates prompt behavior against a matrix of tests. This framework validates prompts with blank-slate subagents and generates artifact documentation including traces and evidence.

What is empirical subagent validation for prompt evaluation?

Empirical subagent validation is a prompt evaluation method that runs prompts against blank-slate subagents to measure requirement achievement. It enables data-driven improvements by reducing bias and hidden errors in instruction design.

Can I use promptfoo with CI-CD pipelines to test prompts automatically?

Yes, you can use promptfoo with CI-CD pipelines to test prompts automatically. The framework sets up a declarative CI regression pipeline that evaluates prompt behavior against a matrix of tests, ensuring reproducible testing and structured evaluation.

How do I evaluate prompts for subagents in Hermes workflows?

You evaluate prompts for subagents in Hermes workflows by applying empirical subagent validation and declarative CI testing. This involves dispatching blank-slate subagents to measure requirement achievement and running promptfoo pipelines for regression testing.

Does prompt evaluation work with AGENTS.md and CLAUDE.md files?

Yes, prompt evaluation works with AGENTS.md and CLAUDE.md files. The framework provides reusable guidance that applies prompt quality validation and regression testing to these files, ensuring consistent instruction correctness across teams.

What's the best way to prevent hidden errors in prompt design?

The best way to prevent hidden errors in prompt design is to use empirical subagent validation and automated CI regression testing. This framework brings rigor to prompt design by reducing bias and validating instruction correctness with blank-slate subagents.
