# Prompt Library Minimal

## Overview

Library of optimized prompts that use minimal tokens while maintaining effectiveness - suitable for production environments that need to reduce costs.

## Why This Matters

- **Cost savings**: Reduce token usage 50-70%
- **Speed**: Fewer tokens = faster responses
- **Proven**: Tested and production-ready
- **Reusable**: Copy-paste ready

---

## Code Review

### Verbose (❌ 85 tokens)
```
I would like you to please review this code carefully and provide
detailed feedback on potential bugs, performance issues, security
vulnerabilities, and code quality concerns. Please also suggest
improvements and best practices that could be applied.
```

### Minimal (✅ 12 tokens)
```
Review for bugs, performance, security. Suggest improvements.
```

**Savings: 86%**

## Bug Fix

### Verbose (❌ 120 tokens)
```
I'm experiencing an issue where the login function is not working
properly. When users try to log in, they receive an error message.
Could you please help me identify what might be causing this problem
and suggest a solution? Here is the relevant code...
```

### Minimal (✅ 18 tokens)
```
Login fails with error. Fix:
[code]

Expected: successful login
Actual: error message
```

**Savings: 85%**

---

## Code Generation

### Verbose (❌ 95 tokens)
```
Please write a function that will calculate the sum of two numbers.
The function should accept two parameters and return their sum.
Please include proper error handling and add comments explaining
what the code does.
```

### Minimal (✅ 15 tokens)
```
Function: sum two numbers
Include: error handling, comments
Language: TypeScript
```

**Savings: 84%**

---

## Refactoring

### Verbose (❌ 110 tokens)
```
I have this code that works but I think it could be improved.
Could you please refactor it to make it more readable, maintainable,
and efficient? Please follow best practices and modern coding standards.
Also, please explain the changes you make.
```

### Minimal (✅ 8 tokens)
```

## Best Practices

### 1. Use Imperative Mood
```
❌ "Could you please write..."
✅ "Write..."

❌ "I would like you to..."
✅ "Create..."
```

### 2. Specify Output Format
```
❌ "Explain this code"
✅ "Explain in 3 bullet points"
```

### 3. Be Specific
```
❌ "Make it better"
✅ "Optimize for speed"
```

### 4. Remove Pleasantries
```
❌ "Thank you for your help"
✅ [omit]

❌ "Please and thank you"
✅ [omit]
```

### 5. Use Abbreviations
```
❌ "TypeScript"
✅ "TS"

❌ "JavaScript"
✅ "JS"

❌ "database"
✅ "DB"
```
