A library of shared system prompts for creating customized educational GPT agents.

About ncwilson78/System-Prompt-Library
The System Prompt Library is an open source GitHub repository of shared system prompts for creating customized educational GPT agents. It is intended for educators and is organized into prompts for educators and prompts for learners. Each prompt includes a summary of its purpose, learning or instructional goals, a basic structure of the interaction it supports, and related materials. The examples were created and shared by Harvard-affiliated educators and by experts in generative AI and education. The repository also describes strategies for designing effective system prompts for education, including incorporating examples, character creation, narrative engagement, self-generated prompts, and sequential reasoning. To use a prompt, users copy it from the code block labeled "Copy This Prompt" and paste it into a custom GPT tool. Each prompt is licensed for reuse, but licensing requirements differ, so users should check them before copying, adapting, or sharing a prompt. The maintainers note that large language models can respond in unexpected or inaccurate ways, so users should review responses and adapt prompts to their learners and teaching context.
