Resource details

For beginners improving chat prompts. This is reading material, not software to install. Start with concrete behavior and examples; a long character description is not an automatic memory system.

Before you start

Platforms
Web browser
Content updated
  • Read the pinned guide in a browser. Use your existing chat tool only if you want to compare responses.
  • Use the site’s fictional exercise and ordinary updates, without private information about other people.

Common pitfalls

  • The pinned guide is older; its model names, APIs, and prices are not current specifications.
  • The main MIT license permits commercial use, modification, and redistribution subject to retaining copyright and the full license. Linked third-party content and model services have separate terms.
  • The exercise is original and does not copy lengthy examples or impersonate a real person or an anime character.
  • Prompt text alone does not store persistent memory, maintain a life clock, or send WeChat messages.

Complete resource

[Small goal] One observable, editable conversation rule and a comparison you perform yourself. Different models may respond differently. [Before you start] Read the pinned guide in a browser. Use your existing chat tool only if you want to compare responses. Use the site’s fictional exercise and ordinary updates, without private information about other people. [Three steps] 1. Read three concepts: Understand the difference between roles, context, and output requirements in the official guide. This entry summarizes those ideas without copying the article or its examples. 2. Replace adjectives with behavior: Write an original rule such as: answer the current topic first, use one to three sentences for casual chat, and give one concrete reason when disagreeing. Add your current topic. 3. Compare the same message: Ask your existing chat tool to answer the same ordinary greeting with the old and revised short instructions. Compare length, relevance, and unearned intimacy. Adjust one rule at a time. [Scope] The pinned guide is older; its model names, APIs, and prices are not current specifications. The main MIT license permits commercial use, modification, and redistribution subject to retaining copyright and the full license. Linked third-party content and model services have separate terms. The exercise is original and does not copy lengthy examples or impersonate a real person or an anime character.

Original guide (Chinese)
【小目标】一条自己能观察和修改的角色说话规则,以及一次由自己完成的对照记录;不保证所有模型都产生相同效果。

【开始前准备】用浏览器阅读固定版本指南;想比较回答时再使用自己已有的聊天工具。
只使用本站自编的虚构练习和普通近况,不提交真实他人隐私。

【三步尝试】1. 先读三个概念:在官方指南里理解角色、上下文和输出要求的区别;本条只概述这些概念,不复制整篇文章或原有示例。
2. 把形容词改成行为:自写一句规则,例如“初次聊天先回应当前话题,普通闲聊一到三句,有不同意见时说一个具体理由”,再加一句自己的当前话题。
3. 用同一句话比较:让已有聊天工具分别按修改前后两份短设定回答同一句普通问候,比较长度、是否接住话题及是否无端亲密;一次调整一个规则。

【适用边界】这份固定指南提交较早,不能把其中模型名称、接口或费用当成当前规格。
主许可MIT允许在条件下商用、修改和再分发,仍需保留版权与完整许可;第三方链接和模型服务另适用自己的条款。
本站练习为原创,不照搬指南中的大段示例或任何真人、动漫人物身份设定。
提示词可约束表达,但不能独自保存长期记忆、设置生活时钟或自动发送微信消息。
