## What is LangGPT?

LangGPT is a structured prompt design framework proposed by Yunzhong Jiangshu in 2023, empowering everyone to become a prompt expert.Regarded as the 'programming language for prompts,' it transforms traditional trial-and-error prompt engineering into a systematic, template-based, and modular methodology.

As the most popular structured prompt paradigm in the Chinese AI community, LangGPT has garnered over 12,700 stars on GitHub and is battle-tested by thousands of users worldwide.Its core philosophy uses hierarchical structures—such as Role, Goal, Rules, and Workflow—to standardize LLM outputs, becoming so deeply integrated into major models that they often recognize the pattern natively.

Users can trigger high-quality structured prompts in models like ChatGPT, Claude, DeepSeek, or Qwen simply by using keywords like 'LangGPT way' or 'Yunzhong Jiangshu.' The project also offers specialized skills for Claude Code and an extensive library of examples, enabling rapid conversion of ideas into reusable prompt modules.

## Key features

- **Structured Templ**：Offers hierarchical organization inspired by programming paradigms, including standard modules like Role, Profile, Goal, Skills, Rules, and Workflow.
- **High Reusability**：Create once and adapt infinitely like code modules; supports variables and conditional logic to significantly improve efficiency.
- **Native Model Sup**：Due to its widespread adoption, major LLMs (such as GPT-4, Claude, Qwen) have implicitly learned the structure, allowing activation via simple keywords.
- **Claude Code Skil**：Provides an official marketplace plugin that enables direct generation of structured prompts using the /langgpt command within Claude Code.
- **Academic Foundat**：Backed by published research on arXiv (arXiv:2402.16929), offering a theoretical basis rather than just empirical tips.
- **Rich Example Lib**：Includes a vast collection of battle-tested prompt templates across design, coding, and writing domains for easy adaptation.

## How to use it

1. Method 1: Direct Trigger.Simply type 'Write a prompt the LangGPT way' or mention 'Yunzhong Jiangshu' in any mainstream LLM chat.
2. Method 2: Use Automated Tools.Leverage tools like LangGPT GPTs, Kimi+ LangGPT, or PromptGPT to assist in generation.
3. Method 3: Master the Template.Learn basic Markdown formatting and manually write prompts following the #Role, ##Profile, ##Goal structure.
4. Method 4: Reference Examples.Browse the Prompts folder in the GitHub repository to copy and adapt existing templates to your needs.
5. Method 5: Install Skill.In Claude Code, install the langgptai/claude_marketplace plugin and use the /langgpt command to invoke capabilities.

## Where it fits

- **Complex Task Bre**：Use LangGPT to clearly define workflows and boundaries when requiring models to perform multi-step, long-logic analysis or creation tasks.
- **Team Prompt Stan**：Establish unified prompt specifications for enterprises or teams to ensure stable and consistent output quality across different members.
- **Vertical Domain**：Define detailed Role and Skill modules to enable general LLMs to act as senior experts in specific fields, providing more professional advice.

## FAQ

### Is LangGPT free to use?

Yes.LangGPT is an open-source project hosted on GitHub under the Apache-2.0 license, allowing anyone to view, download, and use its templates and methodology for free.

### Do I need to memorize the complex template structure?

No.Due to its widespread adoption, most mainstream LLMs have already 'learned' this structure.You can simply mention 'LangGPT' or 'Yunzhong Jiangshu' in your chat, and the model will typically generate a compliant prompt automatically.

### Which LLMs does LangGPT support?

It is compatible with almost all major large language models, including ChatGPT (GPT-4/3.5), Claude, DeepSeek, Gemini, Kimi, Doubao, and Qwen.

### How do I use LangGPT in Claude Code?

You can install the plugin via the official marketplace (/plugin marketplace add langgptai/claude_marketplace) or manually place the langgpt.skill file in the ~/.claude/skills/ directory, then type /langgpt to use it.
