What is the purpose of the .github/copilot-instructions.md file in a repository?
The .github/copilot-instructions.md file contains repository-level custom instructions that GitHub Copilot Chat injects as system context for all conversations in that repository. Teams use it to encode coding standards, architecture decisions, preferred libraries, and naming conventions so Copilot's suggestions align with the codebase's conventions.

A developer uses @workspace in GitHub Copilot Chat. What context does this provide?
The @workspace participant gives Copilot Chat codebase-wide context by indexing the current VS Code workspace. Copilot can answer questions about the project's architecture, find relevant code, and suggest changes consistent with the existing codebase — not just the currently open file.

What does Copilot Enterprise add over Copilot Business for large organizations?
Copilot Enterprise adds capabilities for large organizations: Bing search integration for current docs, knowledge bases built from internal documentation, Copilot Chat in GitHub.com pull requests for PR summaries and review, and improved context understanding using the organization's private code patterns.

An engineer uses Copilot's slash commands like /explain and /fix in the editor. What do these commands do?
Copilot Chat's slash commands invoke predefined behaviors: /explain describes what selected code does in natural language, /fix suggests corrections for compiler errors or code issues, /tests generates unit tests, and /doc adds documentation comments. They provide quick, structured interactions without typing full questions.

A team lead wants Copilot to respect the project's custom ESLint rules when suggesting code. What is the most effective way to communicate this?
While Copilot may read some config files, the most reliable approach is explicitly documenting constraints in .github/copilot-instructions.md. You can describe rules like 'always use named exports', 'avoid var declarations', or 'use async/await not .then() chains' with examples. These custom instructions are directly injected into Copilot's system prompt for every session.
