## 🛠️ Customization
### Adding Your Own Prompts
1. Create a new `.toml` file in the appropriate `commands/` subdirectory:
```bash
mkdir -p commands/mycategory
touch commands/mycategory/myprompt.toml
```
1. Write your prompt:
```toml
prompt = """
# My Custom Prompt
Your prompt content here with {{args}} for user input.
"""
```
1. Restart Gemini CLI to load the new prompt
### Modifying Existing Prompts
Fork the repository and edit any `.toml` file to customize prompts to your needs.
## 📚 Prompt Engineering Tips
Based on the prompts in this library, here are key principles:
### 1. **Be Specific**
```text
❌ "Review this code"
✅ "Perform a security analysis focusing on input validation, SQL
injection, and XSS vulnerabilities"
```
### 2. **Provide Structure**
Use clear sections, numbering, and formatting to guide the AI's response.
### 3. **Include Context**
Specify the language, framework, use case, and constraints.
### 4. **Request Examples**
Ask for code examples, not just explanations.
### 5. **Define Output Format**
Specify exactly how you want the response structured.
### 6. **Use Variables**
Make prompts reusable with `{{args}}` placeholders.
