## 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.

## Disconnect or uninstall

1. **In ChatGPT** Disconnect an account in Settings → Apps or Plugins. To remove the plugin itself, open Prompt Engineer in the Plugin Directory and select Uninstall plugin. Uninstalling can disconnect every account connected through it, and plugins your workspace installs may not offer the option.

2. **In Codex** Run /plugins in the Codex CLI, select the plugin and uninstall it, or press Space to turn it off.

## Skills

- **prompt-design**: Design clear, testable prompts from a user's task and constraints.

- **prompt-refinement**: Diagnose and improve an existing prompt without changing its purpose.
