## About

Class Key retrieves teacher-prepared English lesson settings using a six-character class code. Learners can confirm the lesson title and version, then use the returned scenario, AI role, optional English level, and feedback settings for practice in ChatGPT. The tool does not receive student identities, answers, or chat transcripts. It records usage counts and enforces request limits. Teacher sign-in and in-app reporting on the companion website are not yet available; a public sample lesson is available with code CKTEST.

## How to use

1. **Add it in ChatGPT** Open Class Key in ChatGPT's Plugin directory (button above), select + to add it and sign in if asked.

2. **Use it in a chat** Type @ in the composer and pick Class Key, or start your message with its name. ChatGPT may also suggest it when it fits what you ask.

## Skills

- **lesson-player**: Start or continue a teacher-prepared Class Key English lesson when the learner provides a lesson code or asks to practice with Class Key. Retrieve its fixed-schema settings using get_lesson and follow the activity workflow below.

## Example prompts

- "先生からもらった授業コードで、英語の練習を始めたいです。"
