A comprehensive collection of high-quality, pre-crafted prompts for common software engineering tasks, accessible via simple slash commands in the Gemini CLI.

Install the extension using the Gemini CLI:

gemini extensions install yourusername/prompt-library-extension

Or install from a local directory:

git clone https://github.com/yourusername/prompt-library-extension.git
cd prompt-library-extension
gemini extensions link .

After installation, restart Gemini CLI and start using prompts:

# Review code for security issues
/code-review:security "your code here"

# Generate a README file
/docs:write-readme "describe your project"

# Create unit tests
/testing:generate-unit-tests "your function here"

# Explain a complex concept
/learning:explain-concept "recursion"

# Debug an error
/debugging:debug-error "paste your error here"

1. Create a new .toml file in the appropriate commands/ subdirectory:

   mkdir -p commands/mycategory
   touch commands/mycategory/myprompt.toml

2. Write your prompt:

prompt = """

Your prompt content here with {{args}} for user input. """

3. Restart Gemini CLI to load the new prompt.

## 📚 Prompt Engineering Tips

1. **Be Specific**: Instead of "Review this code", use "Perform a security analysis focusing on input validation".
2. **Provide Structure**: Use clear sections, numbering, and formatting.
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.
