Frequently Asked Questions About GitHub Copilot

The most important answers about GitHub Copilot

GitHub Copilot is an AI assistant for software development that autocompletes code, answers questions, and can collaborate with developers on programming tasks. You can use it in supported code editors and on GitHub, among other places; always verify generated changes for functionality, security, and compatibility with your project.

What is GitHub Copilot, and what is it used for?

What is GitHub Copilot?

GitHub Copilot is an AI-powered programming assistant that helps you understand, write, and review code. It can suggest code completions while you’re coding. You can ask questions about your project via chat. With agent features, you can also have it perform more complex tasks, such as preparing a commit and running relevant checks.

What can you do with GitHub Copilot?

You can have features suggested, existing code explained, tests prepared, and ask for help with error messages. Copilot can also help draft documentation and implement changes. The result depends heavily on the available project information. A clear task with concrete examples usually provides more guidance than simply saying, “improve this application.”

Is GitHub Copilot the same as Microsoft Copilot?

No. GitHub Copilot focuses on software development. The name Microsoft Copilot is also used for other AI products, such as those related to general questions and Microsoft 365. A subscription that includes Copilot in Word or Excel does not automatically mean that GitHub Copilot is included. Be sure to check which product you are actually purchasing.

Is GitHub Copilot the same as ChatGPT?

No. Both can help with programming questions, but GitHub Copilot is integrated into development environments and GitHub workflows. This allows it—depending on the feature—to work with relevant project context and suggest changes. Be sure to compare the way you want to work: asking individual questions or getting help within your programming environment.

Who can benefit from GitHub Copilot?

For developers who regularly write, maintain, or review code. Beginners can ask for explanations of unfamiliar features. Experienced programmers can speed up repetitive tasks. The value isn’t just in producing more code: understanding more quickly why something goes wrong or which components are affected can be just as useful.

Can you program with Copilot without any programming knowledge?

You can have proposals created, but you need the knowledge to evaluate them properly. A working example is not yet a maintainable application. Use Copilot as a learning aid: ask why a solution works, what assumptions it’s based on, and how to test it. Don’t run code just because the explanation sounds convincing.

Installation, devices, and supported editors

What do you need to use GitHub Copilot?

You’ll need a GitHub account, access to a compatible Copilot subscription, and a supported environment. In many editors, you’ll install an extension or plug-in and sign in. For business access, an administrator may first need to assign a key or enable certain features.

How do you get started with GitHub Copilot?

Activate your access, open your editor, and follow the genuine installation procedure. Log in with the correct GitHub account. Then test a small task, such as explaining an existing feature. This allows you to verify that the connection and context are working before proceeding with larger changes.

Does GitHub Copilot work in Visual Studio Code?

Yes. VS Code supports features such as code completion, chat, and agent functions, among others. The available features depend on your version, settings, and subscription. Keep both VS Code and the relevant extensions up to date. If a feature is missing, first check the genuine feature matrix before troubleshooting installation issues.

Does GitHub Copilot work in Visual Studio and JetBrains?

Yes. Visual Studio and supported JetBrains environments also have Copilot integrations. The features aren’t identical across all platforms. Therefore, a demonstration from VS Code may not show the same buttons or workflow as your editor. Compare the support for the specific task you want to perform.

What other editors are supported?

GitHub also mentions environments such as Eclipse, Xcode, and Neovim. The available features vary by integration: for example, code completion may be available while chat or an agent feature may be missing. Use the genuine feature matrix as a starting point and check the required editor and plugin versions.

Can you use Copilot on Windows, Mac, and Linux?

That depends on the editor or application you choose. An environment supported by your operating system may offer access to Copilot. So be sure to check both: the editor’s platform requirements and support for Copilot integration. Not every editor is available on every operating system.

Do you need a powerful computer?

For online AI processing, you don’t need to run a large language model on your own computer. However, your device must be compatible with your development environment. Large projects, local builds, and extensive testing can require a lot of memory or processing power. Copilot doesn’t eliminate those requirements for your project.

Can you use GitHub Copilot offline?

You’ll need an internet connection to use the online AI features. Of course, you can continue to edit existing files locally if your editor supports it. When working offline, don’t rely on brand new Copilot responses. Save relevant explanations and check in advance whether your project can be built and tested independently.

Does your code need to be on GitHub?

For local editor features, you don’t need to first publish every project publicly on GitHub. Features related to repositories, pull requests, and cloud agents have different requirements. Distinguish between assistance within your editor and work that you delegate to an agent on GitHub. Public publishing is not a general requirement for this.

Code Completion and Copilot Chat

How does auto-complete work?

Copilot uses available context to suggest possible follow-up lines or code blocks. You decide for yourself what to adopt. Read a suggestion before accepting it, especially when unfamiliar functions or dependencies appear. Verify that it aligns with the project version and existing conventions.

Can Copilot write a complete function?

Yes, you can have Copilot suggest a function based on a description, existing code, and examples. Include the input, expected output, and error behavior. A clear prompt prevents Copilot from making important decisions on its own. Afterward, also evaluate empty inputs, exceptions, and other situations outside the example.

What is Copilot Chat?

Copilot Chat is the chat feature that lets you ask questions about code and programming tasks. For example, you can ask for an explanation, a suggested change, or help with an error message. Be sure to include relevant context. The question “Why isn’t this working?” provides little information if the problem is in a different file.

Can you speak to Copilot in Dutch?

You can ask questions and provide explanations in Dutch. Keep technical terms, error messages, and code snippets intact as much as possible. Agree on which language you’d like to use for documentation and comments. A question in Dutch does not mean that English API names need to be translated.

Which programming languages does Copilot support?

Copilot can assist with many programming languages, but the quality and support vary depending on the task and environment. Test it with your language, framework, and project version. Common patterns provide more starting points than a rare internal library for which little context is available.

Can Copilot explain existing code?

Yes. Select a function or add relevant files and ask for an explanation tailored to your level of understanding. Have them explain what the input and output are and which other components are called. Verify the explanation against the code; a plausible explanation may still be missing an important detail.

Can Copilot resolve error messages?

They can suggest possible causes and solutions. Please provide the full, relevant error message, the action that preceded it, and the versions you’re using. If the cause is unclear, ask for a diagnosis first. A quick fix may make the error message disappear without resolving the underlying problem.

Can Copilot automatically write tests?

You can have tests prepared and, if appropriate agent functions are available, have them executed. Specify the existing test framework and the desired behavior. Verify that the tests can actually detect errors. A test that merely confirms what the brand new implementation happens to do offers little assurance regarding your genuine requirement.

Can Copilot update documentation?

Yes. You can suggest changes to explanations, examples, and documentation. Make sure they align with the behavior that has actually been implemented. Be sure to check installation commands, configuration, and example values. Documentation that promises something the code doesn’t support actually makes maintenance more difficult.

Agents, code review, and larger tasks

What is agent mode in GitHub Copilot?

Agent mode can tackle a task in multiple steps using the available tools. This includes viewing files, suggesting changes, and performing checks. The offers available depend on your editor and settings. Specify a clear objective and review the changes before finalizing them.

What’s the difference between chat and agent mode?

When you have a general question, you’re mainly looking for an explanation or a suggestion. An agent can also perform offers within the permitted scope. Therefore, be sure to specify clearly whether you want only an analysis or also file modifications. Making that distinction prevents an exploratory conversation from unintentionally turning into a major overhaul of your project.

What is the Copilot Cloud Agent?

The cloud agent works on delegated tasks via GitHub. It can review code, develop an approach, and prepare changes—for example, in a pull request. You don’t have to perform every step yourself in your local editor. Access and capabilities depend on your subscription and organizational policies.

Are Coding Agent and CloudAgent the same thing?

Older documentation often uses the name “Copilot coding agent.” GitHub now uses “cloudagent” for its more extensive capabilities. When consulting manuals, be sure to check the described feature and publication date. An older explanation may still assume a workflow that exclusively involves creating a pull request immediately.

What is a suitable job for a police officer?

Choose a specific change with clear acceptance criteria. For example, adding a missing check or fixing a clearly defined bug. Broad, open-ended tasks leave more room for incorrect assumptions. Also specify which files, interfaces, and behaviors must be preserved.

Example of a specific programming assignment

Add input validation to the existing contact form. An empty email address should trigger a clear error message. Use the validation patterns and tests already included in this project. Keep the existing field names and do not change the form layout. Show which validations you have implemented.

Can Copilot edit multiple files?

Yes, appropriate editing and agent functions can prepare changes across multiple files. Treat the whole process as a single change. A customized function may affect tests, calls, and documentation. Also, be mindful of unnecessary modifications that fall outside your scope of work and make the review more difficult.

What does Copilot code review do?

Copilot code review evaluates changes and provides feedback on potential issues. This can serve as an additional check on a pull request or local change. Treat its findings as suggestions to investigate. The review may miss errors and also provide comments that aren’t applicable to your project.

Does Copilot code review replace human review?

No. An automated review doesn’t automatically account for all product specifications, exceptions, and operational implications. Use it alongside appropriate tests and human evaluation. When making a significant change, be sure to ask whether the behavior makes sense for real users. Technically sound code can still solve the wrong problem.

What is Copilot CLI?

Copilot CLI brings AI support to the command line. This can be useful when working from a terminal. Check suggested commands before executing them, especially if they modify files or call external services. A brief explanation of the implications helps you properly evaluate a suggestion.

Better results with context and instructions

How do you write a good prompt for Copilot?

Specify the goal, the relevant context, and the expected behavior. Include an example if the outcome could be interpreted in multiple ways. Also mention any constraints, such as existing libraries or supported versions. This reduces the number of choices Copilot has to fill in on its own.

What project information do you need to provide?

Start with the files that define the problem: the affected function, calls, error message, and relevant tests. Include the versions used if they impact the solution. Don’t just add the entire project at random. Specific context makes it easier to verify a solution.

What are custom instructions?

Custom instructions are fixed guidelines regarding your preferences or project. For example, you can use them to describe test commands, naming conventions, and architectural guidelines. Support varies by environment. Think of instructions as context: they do not guarantee that every proposal will automatically comply with all rules.

What does copilot-instructions.md do?

The .github/copilot-instructions.md file may contain repository-wide instructions for supported Copilot features. Include specific, up-to-date project information, such as the technologies used and how to perform relevant checks. A concise, accurate file is more useful than a lot of conflicting or outdated instructions.

Why does Copilot suggest a nonexistent feature?

A model may combine patterns into a plausible name that isn’t available. It may also be based on a different library version. Check the suggested APIs in the project dependencies and genuine documentation. Report the limitation you found and request a solution using the options that are actually available.

How can you avoid unnecessarily major changes?

Set clear boundaries and ask to align with existing patterns. Fix a bug without simultaneously designing a brand new architecture. Evaluate changes in small steps. A limited adjustment is easier to test and revert than a major change with multiple objectives.

Free use, subscriptions, and AI credits

Is GitHub Copilot free?

Yes. Copilot Free offers limited access to a selection of features. It’s a good way to try out the service. Check your current usage allowance in your account; older overviews with fixed numbers of chats or add-ons may no longer match your current subscriptions.

What kinds of subscriptions are available?

For individual users, options include Free, Pro, Pro+, and Max. Additionally, there are Student, Business, and Enterprise editions. Compare model access, usage limits, and management features. You should also choose an organizational package based on centralized policies and data agreements—not solely on the amount of AI usage it includes.

How much does GitHub Copilot cost?

The genuine monthly prices for individual subscriptions are currently $10 for Pro, $39 for Pro+, and $100 for Max. Business plans start at $19 per assigned seat per month. Check for taxes, terms and conditions, and any additional usage fees when purchasing.

What are GitHub AI Credits?

GitHub AI Credits track the use of designated Copilot features. Usage may vary by model and task. Therefore, a single query does not automatically equate to a fixed number of credits. Check your current usage overview, especially when using agents or extended chats.

Why do old manuals mention “premium requests”?

GitHub has changed the usage measurement for many subscriptions from premium requests to AI Credits. Certain existing annual subscriptions may temporarily still be subject to older terms. Therefore, please check the billing information in your own account. Do not simply convert an old request limit to the current credit platform.

Is a paid subscription completely unlimited?

No. Access to features does not mean that all models and agent tasks are available without usage limits. Check the included storage space and additional costs separately. Terms such as “base credits” and “additional allowance” may have different conditions. The monthly fee alone does not indicate what intensive use will ultimately cost.

Are there any additional costs?

Yes, depending on your subscription, budget settings, and the services you use. Be sure to set any limits for additional usage. Also keep an eye on linked services: certain workflows may consume other resources in addition to AI usage. Before undertaking a large task, check which costs fall under which service.

Can students get Copilot for free?

Verified students may be eligible for Copilot Student. Opportunities are also available for certain teachers and administrators of popular open-source projects. Eligibility is not automatic. Check the current terms and conditions and your verification status before planning to set up a free subscription as a permanent arrangement.

Privacy, source code, and usage rights

Will your code be sent to an AI service?

When providing answers and suggestions, Copilot processes relevant context through the service being used. The information taken into account depends on the feature, environment, and settings. For business projects, check your organization’s policies. A file opened locally does not automatically mean that AI processing takes place entirely on your computer.

Does GitHub Copilot use your data for model training?

For individual subscriptions, interaction data may be used in accordance with the applicable settings and terms. GitHub offers the option to opt out of this. For Copilot Business and Enterprise, GitHub states that this data is not used to train its models. Check which subscription your session is using.

How do you disable training based on your interaction data?

Open the Copilot settings in your GitHub account and review the privacy options for the use of interaction data. You can find this setting at github.com/settings/copilot/features. Save or confirm your selection when prompted. For business use, also check whether your organization’s policies require additional settings.

Can you use Copilot with confidential source code?

This requires a review of your contract, subscription, and organizational policies. Verify which data may be processed and which functions are permitted. Do not include passwords, private keys, or other confidential information in prompts. For examples, use fictitious values that illustrate the same technical issue.

Could a suggested code resemble a publicly available code?

Yes. GitHub notes that suggestions may match code from public repositories. Depending on your settings, certain matches may be blocked or displayed with source information. Check available references and keys. An AI suggestion is not an automatic guarantee that all rights issues have been resolved.

Can you use the generated code for commercial purposes?

Review the applicable terms and conditions, any source references, and keys for the components used. Existing project agreements also remain in effect. Commercial use also requires technical review: you must understand which dependencies and data flows you are introducing. Discuss any special requirements with the person in charge within your organization.

Troubleshooting and verifying changes

Why doesn’t Copilot appear in my editor?

Check whether your environment supports the desired feature and whether the extension is active and up to date. Then check which account you’re logged in with. With business access, a key or setting may be missing. Start with these checks before reinstalling the full editor.

Why isn’t Copilot responding, or why does it stop a task?

Possible causes include connection issues, authentication problems, usage limits, or organizational policies. Check error messages and the usage overview. Also review genuine outage information. When submitting a support request, note the environment, version, and affected feature, without unnecessarily including confidential code or secrets.

Why can’t Copilot find all project files?

Available context depends on the environment and function. A file may fall outside the open workspace or not be part of the selected context. Add relevant information in a targeted manner and ask which files were used. Don’t let an assumption about missing code go unnoticed and influence the solution.

What should you check before entering your Copilot code?

Read the change and verify that it resolves the intended issue. Perform appropriate tests and review error cases. Also pay attention to changes outside the scope of the task. Code that compiles may still handle user permissions, invalid input, or existing data incorrectly.

• Behavior: Is the result correct for both normal and abnormal input?
• Project: Do the interfaces, versions, and dependencies align with the existing code?
• Security: Are access control and data protection maintained?
• Maintenance: Have relevant tests, documentation, and source references been verified?
