19. Features Gemini Code Assist
20. To improve test coverage for a code base a dev is not familiar with, they can I ask Gemini Code Assist to explain the code so to quickly and effectively understand how to start testing it. IDE Coverage Gemini Code Assist: Explain Code in a Chat Assistive Development
21. Devs are made aware when a suggestion falls under a permissive license and receive the information to provide license attribution, so their organization can stay compliant with license terms IDE Coverage Assistive Development Gemini Code Assist: License Attribution
22. 2 2 AI-assisted app development AI code generation, code completion and natural language chat across multiple IDEs. Enterprise-context aware No training on customer data + customized assistance for you use, with customer managed storage. Enterprise security, privacy & IP protection Helps protect your data and IP with built-in security features Gemini Code Assist: AI Assisted
23. Assistive Development Devs can write high quality code faster and stay in a flow state longer so they can be productive translating their idea into code. IDE Coverage Gemini Code Assist: Code Completion
24. IDE Coverage Gemini Code Assist: Code Transformation Assistive Development Developers can use natural language prompts to perform modifications on existing code, such as adding comments, bugfixing or making code more readable
25. To define a test plan to ensure the code works as intended. Devs can ask Gemini Code Assist to suggest a unit test plan for the code, and iterate on it to ensure good coverage of edge cases. IDE Coverage Gemini Code Assist: Suggest a Test Plan Assistive Development
26. Once the test plan looks good, Devs can ask Gemini Code Assist to implement the test plan defined. IDE Coverage Gemini Code Assist: Test Generation Assistive Development

37. Best Practices Gemini Code Assist
38. https://www.cloudskillsboost.google/focuses/104240
39. Proprietary and Confidential 1. Master the Prompt Framework The quality of your output is directly tied to the "Context-Action-Format" framework: • Persona: Give Gemini a role (e.g., "Act as a Senior Go Engineer focused on high-performance concurrency"). • Context: Use the @ symbol in chat to select specific remote repositories or local files. This ensures Gemini "knows" your project’s architecture. • Constraints: Be explicit about what not to do (e.g., "Do not use external libraries beyond the standard library").
40. Proprietary and Confidential 2. Use Integrated Smart Commands Rather than typing long instructions, use the slash commands and keyboard shortcuts to trigger specific workflows: • /fix: Use this on selected code to resolve syntax errors or potential bugs (like NullPointerExceptions). • /doc: Automatically generates high-quality documentation for a function or class. • /generate: Best for creating new boilerplate or logic (e.g., /generate a Cloud Storage bucket connection). • /simplify: Ideal for refactoring complex if statements or overly verbose logic.
41. Proprietary and Confidential 3. Optimize the "Agentic" Workflow • Atomic Tasks: Execute only one action per prompt. If you want to retrieve a function and then implement it elsewhere, do it in two separate steps for better accuracy. • Open Local Files: Generating unit tests works best if the relevant file is already open in your IDE. Gemini uses the active tab as its primary focus. • Next Edit Predictions: Enable this in your VS Code settings. It uses AI to predict your next move, allowing you to "Tab" through common refactoring patterns.
