Advanced AI Agent for Prompt Evaluation & Model Testing

Advanced AI Agent for Prompt Evaluation & Model Testing

This AI agent skill is designed to facilitate prompt evaluation and model testing for developers utilizing Claude Code, Cursor, or Codex. It supports systematic testing of AI prompts, evaluation of large language model (LLM) outputs, and the execution of red-team vulnerability scans. The skill integrates with local evaluation configurations, ensuring safe control over providers and costs.

What this skill does

• Evaluates LLM applications and AI prompts through systematic testing.
• Performs red-team/vulnerability testing on target models or applications.
• Utilizes existing evaluation tools defined in project dependencies, scripts, or toolchains, such as promptfoo, evals, or braintrust.
• Provides cost, provider, API key, and network target confirmations before execution.
• Supports a workflow that includes defining risk, choosing assertion types, and establishing evaluation criteria.

Who it is for

This skill is particularly useful for developers and teams working with AI coding agents like Claude Code, Cursor, and Codex, who need reliable tools for prompt evaluation and model testing.

Use cases

• Systematic testing of prompts in AI applications to ensure expected behavior.
• Conducting vulnerability assessments on models to identify potential weaknesses.
• Ensuring model outputs conform to predetermined assertions such as text inclusion/exclusion, schema compliance, or performance metrics like cost and latency.

Technical details

• Integrates with prompt evaluation runners available in local toolchains.
• Employs deterministic checks including contains, regex, json-schema, cost, and latency.
• Allows for custom logic implementation using javascript or python where applicable.
• For authorized security testing, defensive research, and educational use only.
