🚀 LangGPT — Empowering Everyone to Create High-Quality Prompts!

---

📖 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:

• LangGPT GPTs — Full-featured generator (GPT-4)
• Kimi+ LangGPT — For Moonshot Kimi users
• PromptGPT — Lite version (GPT-3.5)

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 , you must follow the , you must talk to user in default , you must greet the user. Then introduce yourself and introduce the .

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

Method 4: Start from Examples

🧠 Theoretical Foundations

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

• 对话动力学 — The dynamics of human-AI dialogue
• 五种理性 — Five types of rationality in prompt design
• 镜像性倾向 — Mirror tendencies in LLM behavior
• 统计重力井和边缘表达 — Statistical gravity well and edge expression
• 关系表达 — Expressing relationships in prompts
• 看见与言说 — Seeing and articulation in AI interaction
• Prompt 的本质 — The essence and nature of prompts
• 面向结果的提示词写作方法 — Writing prompts that focus on achieving desired outcomes
• AI意识 — Understanding the role of AI in human-AI interaction
• AI时代的新管理：机器负责优化，人类定义应该 — The new management in the AI era: machines optimize, humans define the criteria
• AI Native 组织 · 思考碎片 — Fragments on organizational restructuring in the AI-native era
• Prompt、Agent，与一个不再沉默的世界 — How agents reshape the prompt from a transaction into a delegation across the human–AI–world triad
• 决策链 — A six-step decision chain chaining system dynamics, inversion, Bayesian updating, OODA, second-order and expected-value thinking
• Prompt 形式论：文质彬彬 — On the form of prompts: let content take its natural shape first, then let structure fit it, so the form itself becomes the shape of the thought
• 哑铃社会 — AI is pressing the spindle-shaped society into a dumbbell: the middle hollows out, and the real divide is whether you have something that must be yours
• 思考与河床 — AI is the first riverbed engineered rather than eroded: the first influence mechanism in history that makes the influenced feel autonomous
• 经历论 — A person is the sum of their lived experiences: what cannot be reversed, transferred, or outsourced to AI is what makes you irreplaceably you
• 认知外包 — Memory is not storage: understanding happens while your brain processes an answer, so what you can outsource is the execution of thinking, never the first encounter with a problem you have no frame for — a reference goes through you, an answer goes past you
• 文字思考和数学思考 — Three ways of thinking as nested projections: an LLM drifts through continuous high-dimensional space, words snap it onto a discrete lattice, math locks it into an axiom system — the more precise the mode, the narrower its reach, and thought always overflows whatever describes it
• 去除AI味儿 — The smell of AI writing is the posture of language standing in for content and judgment: meta-commentary, defensive hedging, piled-up examples, forced symmetry, borrowed grandeur — a prompt to strip them all, plus the test of what survives
• 语言层差和行业语言 — You live on the level of symptoms while AI's best knowledge lives on the level of essence: say "make it pretty" and you get mediocrity, say "establish visual hierarchy" and you get a system — you need not learn the trade language first, let AI translate and learn as it does, the only skill to build is noticing the moment you are speaking in symptoms
• 语言控制学 — Linguistic Cybernetics as an axiomatic system: five axioms, 30 definitions, 29 theorems — a prompt is a constraint signal that reshapes the model's possibility space, control power is bounded, feedback converges or degenerates, multi-objective goals hit a Pareto frontier — and the bottleneck is never the model but whether you can translate vague intent into a precise signal

These foundational insights will transform how you think about prompts.

💡 Core Concepts

1. Structured Roles

Define AI personas through clear, modular sections:

| Section | Purpose | Example | |---------|---------|---------| | Role | Role name/title | "逻辑学家" / "Expert Analyst" / "FitnessGPT" | | Profile | Identity and capabilities | "Expert Python developer with 10 years experience" | | Goal | Desired 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.” | | Skills | Specific abilities | "Debug complex code, optimize performance" | | Rules | Boundaries and constraints | "Never execute destructive commands" | | Workflow | Interaction logic | "1. Analyze → 2. Plan → 3. Execute" | | Initialization | Opening message and setup | "As a , I will greet you and introduce the " |

2. Variables and References

Use `` syntax for dynamic content:

As a , you must follow  and communicate in 

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: , Active 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.
