# 🧬 Glue Coding

> **The holy grail and silver bullet of software engineering - finally here.**

---

## 🚀 Disruptive Manifesto

**Glue Coding is not a technology, but a revolution.**

It might perfectly solve the three fatal flaws of Vibe Coding:

| Traditional Vibe Coding Pain Points | Glue Coding Solution |
|:---|:---|
| 🎭 **AI Hallucinations** - Generates non-existent APIs, incorrect logic | ✅ **Zero Hallucinations** - Uses only validated, mature code |
| 🧩 **Complexity Explosion** - The larger the project, the more out of control | ✅ **Zero Complexity** - Each module is a battle-tested wheel |
| 🎓 **High Barrier** - Requires deep programming skills to master AI | ✅ **No Barrier** - You only need to describe "how to connect" |

---

## 💡 Core Concept

```
Traditional Programming: Humans write code
Vibe Coding: AI writes code, humans review code
Glue Coding: AI connects code, humans review connections
```

### Paradigm Shift

**A fundamental shift from "generation" to "connection":**

- ❌ No longer letting AI generate code from scratch (source of hallucinations)
- ❌ No longer reinventing the wheel (source of complexity)
- ❌ No longer requiring you to understand every line of code (source of high barrier)

- ✅ Only reusing mature, production-validated open-source projects
- ✅ AI's sole responsibility: understand your intent, connect modules
- ✅ Your sole responsibility: clearly describe "what is the input, what is the desired output"

## 🎯 Why is this a Silver Bullet?

### 1. Hallucination Issue → Completely Disappears

AI no longer needs to "invent" anything. It only needs to:
- Read Module A's documentation
- Read Module B's documentation
- Write the data transformation from A → B

**This is what AI excels at, and what is least prone to errors.**

### 2. Complexity Issue → Transferred to the Community

Behind each module are:
- Discussions from thousands of Issues
- Wisdom from hundreds of contributors
- Years of production environment refinement

**You are not managing complexity; you are standing on the shoulders of giants.**

### 3. Barrier Issue → Reduced to a Minimum

You don't need to understand:
- Underlying implementation principles
- Best practice details
- Edge case handling

You only need to speak plain language:
> "I want to take messages from Telegram, process them with GPT, and store them in PostgreSQL"

**AI will help you find the most suitable wheels and glue them together.**

## 📋 Practice Flow

```
1. Define the Goal
   └─→ "I want to implement XXX functionality"

2. Find the Wheels
   └─→ "Are there any mature libraries/projects that have done something similar?"
   └─→ Let AI help you search, evaluate, and recommend

3. Understand the Interfaces
   └─→ Feed the official documentation to AI
   └─→ AI summarizes: what is the input, what is the output

4. Describe the Connection
   └─→ "The output of A should become the input of B"
   └─→ AI generates glue code

5. Validate and Run
   └─→ Runs successfully → Done
   └─→ Errors → Give the errors to AI, continue gluing
```

## 🔥 Classic Case Study

### Case: Polymarket Data Analysis Bot

**Requirement**: Real-time acquisition of Polymarket data, analysis, and push to Telegram

**Traditional Approach**: Write a crawler, analysis logic, and bot from scratch → 3000 lines of code, 2 weeks

**Glue Approach**:
```
Wheel 1: polymarket-py (Official SDK)
Wheel 2: pandas (Data Analysis)
Wheel 3: python-telegram-bot (Message Push)

Glue Code: 50 lines
Development Time: 2 hours
```

## 🎖️ Summary

> **If you can copy, don't write. If you can connect, don't build. If you can reuse, don't originate.**

Glue Coding is the ultimate evolution of Vibe Coding.

It's not laziness; it's the **highest embodiment of engineering wisdom** —

Leveraging maximum productivity with minimal original code.

**This is the silver bullet software engineering has been waiting for for 50 years.**

*"The best code is no code at all. The second best is glue code."*

# Glue Coding Methodology

## **1. Definition of Glue Coding**

**Glue Coding** is a new software construction approach, with its core philosophy being:

> **Almost entirely reusing mature open-source components, combining them into a complete system with minimal "glue code"**

It emphasizes "connecting" rather than "creating," and is especially efficient in the AI era.

## **2. Background**

Traditional software engineering often requires developers to:

* Design architecture
* Write logic themselves
* Manually handle various details
* Reinvent the wheel repeatedly

This leads to high development costs, long cycles, and low success rates.

However, the current ecosystem has fundamentally changed:

* There are countless mature open-source libraries on GitHub
* Frameworks cover various scenarios (Web, AI, distributed, model inference…)
* GPT / Grok can help search, analyze, and combine these projects

In this environment, writing code from scratch is no longer the most efficient way.

Thus, "Glue Coding" has emerged as a new paradigm.

## **3. Core Principles of Glue Coding**

### **3.1 Don't write what can be avoided, write as little as possible**

Any functionality with an existing mature implementation should not be reinvented.

### **3.2 Copy-paste whenever possible**

Directly copying and using community-validated code is a normal engineering process, not laziness.

### **3.3 Stand on the shoulders of giants, rather than trying to become one**

Utilize existing frameworks instead of trying to write a "better wheel" yourself.

### **3.4 Do not modify the original repository code**

All open-source libraries should ideally remain immutable and be used as black boxes.

### **3.5 Minimize custom code**

The code you write should only be responsible for:

* Combination
* Invocation
* Encapsulation
* Adaptation

This is what is called the **glue layer**.

## **4. Standard Process of Glue Coding**

### **4.1 Clarify Requirements**

Break down the system's desired functionalities into individual requirements.

### **4.2 Use GPT/Grok to Deconstruct Requirements**

Let AI refine requirements into reusable modules, capabilities, and corresponding subtasks.

### **4.3 Search for Existing Open-Source Implementations**

Utilize GPT's web browsing capabilities (e.g., Grok):

* Search for corresponding GitHub repositories for each sub-requirement
* Check for existing reusable components
* Compare quality, implementation methods, licenses, etc.

#### 🔍 Use GitHub Topics to Precisely Find Wheels

**Method**: Let AI help you find GitHub Topics corresponding to your needs, then browse popular repositories under that topic.

**Example Prompt**:
```
I need to implement [Your Requirement]. Please help me:
1. Analyze which technical fields this requirement might involve
2. Recommend corresponding GitHub Topics keywords
3. Provide GitHub Topics links (format: https://github.com/topics/xxx)
```

**Common Topics Examples**:
| Requirement | Recommended Topic |
|:---|:---|
| Telegram Bot | [telegram-bot](https://github.com/topics/telegram-bot) |
| Data Analysis | [data-analysis](https://github.com/topics/data-analysis) |
| AI Agent | [ai-agent](https://github.com/topics/ai-agent) |
| CLI Tool | [cli](https://github.com/topics/cli) |
| Web Scraper | [web-scraping](https://github.com/topics/web-scraping) |

**Advanced Tips**:
- [GitHub Topics Homepage](https://github.com/topics) - Browse all topics
- [GitHub Trending](https://github.com/trending) - Discover popular new projects
- Combine multiple Topic filters: `https://github.com/topics/python?q=telegram`

### **4.4 Download and Organize Repositories**

Pull the selected repositories locally and organize them by category.

### **4.5 Organize by Architectural System**

Place these repositories within the project structure, for example:

```
/services
/libs
/third_party
/glue
```

And emphasize: **Open-source repositories, as third-party dependencies, must absolutely not be modified.**

### **4.6 Write Glue Layer Code**

The role of glue code includes:

* Encapsulating interfaces
* Unifying input and output
* Connecting different components
* Implementing minimal business logic

The final system is composed of multiple mature modules.

## **5. Value of Glue Coding**

### **5.1 Extremely High Success Rate**

Because it uses community-validated, mature code.

### **5.2 Extremely Fast Development Speed**

A large amount of functionality can be directly reused.

### **5.3 Reduced Costs**

Time costs, maintenance costs, and learning costs are significantly reduced.

### **5.4 More Stable Systems**

Relies on mature frameworks rather than individual implementations.

### **5.5 Easy to Extend**

Capabilities can be easily upgraded by replacing components.

### **5.6 Strong Synergy with AI**

GPT can assist in searching, deconstructing, and integrating, making it a natural enhancer for glue engineering.

## **6. Glue Coding vs. Traditional Development**

| Project | Traditional Development | Glue Coding |
| ------ | ----- | ------ |
| Feature Implementation | Write yourself | Reuse open-source |
| Workload | Large | Much smaller |
| Success Rate | Uncertain | High |
| Speed | Slow | Extremely fast |
| Error Rate | Prone to pitfalls | Uses mature solutions |
| Focus | "Building wheels" | "Combining wheels" |

## **7. Typical Application Scenarios for Glue Coding**

* Rapid prototype development
* Small teams building large systems
* AI applications/model inference platforms
* Data processing pipelines
* Internal tool development
* System Integration

## **8. Future: Glue Engineering will Become the New Mainstream Programming Paradigm**

As AI capabilities continue to strengthen, future developers will no longer need to write large amounts of code themselves, but rather:

* Find wheels
* Combine wheels
* Intelligently connect components
* Build complex systems at extremely low cost

Glue Coding will become the new standard for software productivity.
