Scenarios & Prompt Examples ​

Case Slides This slide is created based on the following content by Gemini CLI. ​

What is Gemini CLI? ​

Gemini CLI is an open-source command-line AI tool that integrates Google's Gemini model directly into your terminal.

• Powerful code processing capabilities: Supports context of over 1 million tokens.
• Seamless shell integration: Can directly execute and understand shell commands.
• File system awareness: Capable of reading and analyzing local files and directories.

Case 1: Code Development & Project Analysis ​

Scenario: Understanding complex code, automatic code generation, and large-scale refactoring.

Prompt Examples:

• Code explanation:

  bash

  > Explain the core functionality of @/path/to/complex-module.js
• Generate unit tests:

  bash

  > Write unit tests for the calculateTotal function in @/path/to/logic.ts
• Project refactoring:

  bash

  > Refactor the entire project to support a new database abstraction layer: > 1. Identify all database-related code > 2. Create a unified data access interface > 3. Generate migration plan and timeline

Case 2: Automated Operations & DevOps ​

Scenario: Simplifying Git operations, generating release notes, optimizing CI/CD workflows.

Prompt Examples:

• Generate commit messages:

  bash

  > Summarize the current git diff changes and write a concise commit message
• Analyze Git history:

  bash

  > Analyze recent git commit history, summarize main changes and generate concise release notes
• CI/CD optimization:

  bash

  > Optimize our CI/CD workflow: analyze build time bottlenecks, suggest parallelization strategies, create intelligent test selection

Case 3: File Management & Data Organization ​

Scenario: Intelligently organizing messy folders, automatically categorizing files based on content.

Prompt Examples:

• PARA method organization:

  bash

  > I want to organize my folders using the PARA system. Please first scan the current directory structure, then propose a reorganization plan.
• Smart image categorization:

  bash

  > Analyze all image files in the current directory and automatically categorize them into different folders based on content, capture time, and scenes.
• Invoice organization:

  bash

  > Organize my PDF invoices by expense month.

Case 4: Content Creation & Document Management ​

Scenario: Quickly generating project documentation, API references, and meeting minutes.

Prompt Examples:

• Generate README:

  bash

  > Generate a README.md file for this project, including project introduction, installation instructions, usage methods, and contribution guidelines
• Generate API documentation:

  bash

  > Generate complete API documentation based on @api-spec.json, including interface descriptions, parameter definitions, and example code
• Knowledge base Q&A:

  bash

  > Based on all documents in the @knowledge-base/ directory, answer questions about project architecture

Case 5: Multimodal Application Development ​

Scenario: Converting design mockups, PDF documents, or even sketches directly into functional code.

Prompt Examples:

• UI design to code:

  bash

  > Based on this UI design mockup (@design.png), create a React application with pixel-perfect UI components and responsive design
• PDF to code:

  bash

  > Analyze this API specification document (@api_spec.pdf) and generate: > 1. Complete TypeScript interface definitions > 2. API client wrapper class > 3. Unit test cases
