## About

Turn goals and constraints into clear, model-aware prompts; improve existing prompts while preserving intent; and design practical evaluation cases to compare quality, reliability, and safety. Distinguish prompt-only behavior from capabilities that require tools or application code. Treat prompt results as empirical, model-dependent—not guaranteed.

## Install

1. **Add it in ChatGPT** Open Plugins in the ChatGPT sidebar (web or desktop), search for “Prompt Engineer” and select +. You'll be asked to sign in to any connected service on first use. Then type @ in a chat to call it.

## Skills

- **prompt-design**: Design clear, testable prompts from a user's task and constraints.
- **prompt-evaluation**: Build practical tests and rubrics for comparing prompt behavior.
- **prompt-refinement**: Diagnose and improve an existing prompt without changing its purpose.
- **prompt-router**: Route prompt requests into drafting, refinement, evaluation, or safety review.
- **prompt-safety**: Review prompt behavior for privacy, injection, deception, and misuse risks.

- "Help me design a prompt for this task and ask only for essential missing context."
- "Improve this prompt while preserving my intent; explain the important changes."
- "Create a small test set and rubric to evaluate these prompt versions."
