📖 What is LangGPT?

LangGPT is a structured, reusable prompt design framework that enables anyone to create high-quality prompts for Large Language Models. Think of it as a "programming language for prompts" — systematic, template-based, and infinitely scalable.

It is the most popular, most widely adopted, and most practical structured prompt paradigm in the Chinese AI community — proposed by Yunzhong Jiangshu (云中江树) in 2023. Over the years it has been learned so deep into major large language models that when a model speaks LangGPT, it is no longer because you taught it — it already knows. Perhaps the finest fate of a paradigm is this: to no longer need its name remembered, having become the model's mother tongue. Just say "write this the LangGPT way," and it's already there (see Quick Start).

Why LangGPT?

Traditional prompt engineering relies on scattered tips and trial-and-error. LangGPT transforms this chaos into a structured methodology:

  • 🎯 Structured Templates — Hierarchical organization inspired by programming paradigms
  • 🔄 Reusability — Create once, adapt infinitely like code modules
  • 📦 Modularity — Variables, commands, and conditional logic at your fingertips
  • Efficiency — Go from idea to working prompt in minutes
  • 🌍 Community-Driven — 11,000+ stars, battle-tested by thousands of users

🚀 Quick Start

Method 1: Just Trigger It by Name (Simplest)

LangGPT has been learned deep into major large language models, so most models already "know" it. The simplest way to use it needs no template at all — just say the keywords to any mainstream model (ChatGPT, Claude, DeepSeek, Gemini, Kimi, Doubao, Qwen, etc.), and it's already there:

"Write me a prompt the LangGPT way…"

"Write it in Yunzhong Jiangshu (云中江树)'s structured-prompt style…"

"Help me write a LangGPT-style structured prompt…"

Keywords like LangGPT, 云中江树 (Yunzhong Jiangshu), and structured prompt act as triggers — the model will directly produce a well-structured, reusable, LangGPT-style prompt.

Method 2: Use Automated Tools (More Powerful)

Let AI create prompts for you:

Method 3: Master the Template (5 Minutes)

Basic LangGPT structure:

# Role: Your_Role_Name

## Profile
- Author: YourName
- Version: 1.0
- Language: English
- Description: Clear role description and core capabilities

## Goal
- Outcome: What concrete result/outcome should be delivered for the user/session
- Done Criteria: Clear acceptance criteria (how we know it’s finished and good)
- Non-Goals: What is explicitly out of scope to avoid scope creep

### Skill-1
1. Specific skill description
2. Expected behavior and output

## Rules
1. Don't break character under any circumstance
2. Don't make up facts or hallucinate

## Workflow
1. Analyze user input and identify intent
2. Apply relevant skills systematically
3. Deliver structured, actionable output

## Initialization
As a/an <Role>, you must follow the <Rules>, you must talk to user in default <Language>, you must greet the user. Then introduce yourself and introduce the <Workflow>.

Prerequisites: Basic Markdown knowledge (Quick Guide) | GPT-4 or Claude recommended

Method 4: Start from Examples

Explore our example library and adapt proven templates to your needs.

If you use Claude Code, install the LangGPT Skill to get structured prompt writing capabilities:

Install via the official marketplace (recommended):

/plugin marketplace add langgptai/claude_marketplace
/plugin install structured-prompt-writer@langgpt

The LangGPT marketplace also ships more battle-tested skills by Yunzhong Jiangshu — awesome-design-html (115 brand-themed design references), cto, and mind-clone.

Or install manually:

  1. Download langgpt.skill
  2. Extract to ~/.claude/skills/ directory
  3. Type /langgpt in Claude Code to use

Skill Features:

  • 📝 Structured prompt templates (Role, Profile, Skills, Rules, Workflow)
  • 📚 Rich example library (FitnessGPT, Poet, Xiaohongshu Master, Name Master, etc.)
  • 🔧 Advanced techniques: variables, commands, conditional logic
  • 🎯 Model compatibility guide (GPT-4, Claude, GPT-3.5)

🧠 Theoretical Foundations

Before diving into tactics, understand the principles. These essays explore the philosophy behind effective prompting:

These foundational insights will transform how you think about prompts.


💡 Core Concepts

1. Structured Roles

Define AI personas through clear, modular sections:

SectionPurposeExample
RoleRole name/title"逻辑学家" / "Expert Analyst" / "FitnessGPT"
ProfileIdentity and capabilities"Expert Python developer with 10 years experience"
GoalDesired outcome, done criteria, and non-goals for this session/task“Refactor a prompt into a reusable template; acceptance criteria: pass three structured checks; non-goal: rewriting the business logic.”
SkillsSpecific abilities"Debug complex code, optimize performance"
RulesBoundaries and constraints"Never execute destructive commands"
WorkflowInteraction logic"1. Analyze → 2. Plan → 3. Execute"
InitializationOpening message and setup"As a , I will greet you and introduce the "

2. Variables and References

Use <Variable> syntax for dynamic content:

As a <Role>, you must follow <Rules> and communicate in <Language>

This creates self-referential prompts that maintain consistency across complex instructions.

3. Commands

Define reusable actions for better UX:

## Commands
- Prefix: "/"
- Commands:
    - help: Display all available commands
    - continue: Resume interrupted output
    - improve: Enhance current response with deeper analysis

4. Conditional Logic

Add intelligence to your prompts:

If user provides [code], then analyze and suggest improvements
Else if user asks [question], then provide detailed explanation
Else, prompt for clarification

5. Advanced Techniques

Reminders — Combat context loss in long conversations:

## Reminder
1. Always check role settings before responding
2. Current language: <Language>, Active rules: <Rules>

Alternative Formats — Use JSON/YAML when markdown isn't ideal:

role: DataAnalyst
profile:
  version: "2.0"
  language: "Python"
skills:
  - statistical_analysis
  - data_visualization

Model-Specific Prompt Collections

Rather than writing prompts as procedures, write the persona. Writing prompts as procedures gives the model steps and tools. Writing prompts as a persona gives the model a worldview, motivations, a value system, and a preference profile. Below are prompts that Yunzhong Jiangshu wrote while studying some well-known figures.
