A/B Equivalence Tester for LLM Documents

A/B Equivalence Tester for LLM Documents

The A/B Equivalence Tester for LLM Documents is a specialized tool designed to compare two versions of a document directed by a Language Model (LLM). It evaluates the original, known as the 'teacher', against the candidate, referred to as the 'student', across a set of inputs, returning a verdict on behavioral equivalence and an efficiency signal.

What this skill does

• Triggers when tasked to A/B test two document versions to ensure that a rewritten or compressed document retains the behavioral characteristics of the original.
• Validates behavioral equivalence between the teacher and the student documents by assessing actions across a transfer set.
• Serves as a transform-agnostic capability, meaning it is independent of the method used to produce the candidate document.
• Supports other optimization transforms by gating processes like compression and directive-clarity to ensure behavioral sameness.
• Integrates as a library capability within agent-skills to facilitate skills that require equivalence testing to function effectively.

Who it is for

This skill is intended for developers and teams utilizing AI coding agents such as Claude Code, Cursor, or Codex. It is particularly beneficial for those looking to ensure consistency and reliability in LLM-directed documents when implementing modifications or optimizations.

Use cases

• Conduct A/B testing of modified prompts or instructions to validate equivalence with the original document.
• Integrate with workflow pipelines to automatically check behavioral parity when documents are compressed or directives clarified.
• Used by teams focusing on document transformation processes where preserving original behavior is critical to operations.

Technical details

• Integrates with capabilities such as agent-skills, aiapplication, and ab-equivalence tools.
• Designed to support usage within AI agent ecosystems, including but not limited to Claude Code, Cursor, and Codex.
• Operates as a modular library feature that can be composed with other skills to enhance document processing reliability.
