Guidelines for structuring code and projects to maximize GitHub Copilot effectiveness through better context management **

Context Engineering

Principles for helping GitHub Copilot understand your codebase and provide better suggestions.

Project Structure

  • Use descriptive file paths: src/auth/middleware.ts > src/utils/m.ts. Copilot uses paths to infer intent.
  • Colocate related code: Keep components, tests, types, and hooks together. One search pattern should find everything related.
  • Export public APIs from index files: What's exported is the contract; what's not is internal. This helps Copilot understand boundaries.

Code Patterns

  • Prefer explicit types over inference: Type annotations are context. function getUser(id: string): Promise<User> tells Copilot more than function getUser(id).
  • Use semantic names: activeAdultUsers > x. Self-documenting code is AI-readable code.
  • Define constants: MAX_RETRY_ATTEMPTS = 3 > magic number 3. Named values carry meaning.

Working with Copilot

  • Keep relevant files open in tabs: Copilot uses open tabs as context signals. Working on auth? Open auth-related files.
  • Position cursor intentionally: Copilot prioritizes code near your cursor. Put cursor where context matters.
  • Use Copilot Chat for complex tasks: Inline completions have minimal context. Chat mode sees more files.

Context Hints

  • Add a COPILOT.md file: Document architecture decisions, patterns, and conventions Copilot should follow.
  • Use strategic comments: At the top of complex modules, briefly describe the flow or purpose.
  • Reference patterns explicitly: "Follow the same pattern as src/api/users.ts" gives Copilot a concrete example.

Multi-File Changes

  • Describe scope first: Tell Copilot all files involved before asking for changes. "I need to update the User model, API endpoint, and tests."
  • Work incrementally: One file at a time, verifying each change. Don't ask for everything at once.
  • Check understanding: Ask "What files would you need to see?" before complex refactors.

When Copilot Struggles

  • Missing context: Open the relevant files in tabs, or explicitly paste code snippets.
  • Stale suggestions: Copilot may not see recent changes. Re-open files or restart the session.
  • Generic answers: Be more specific. Add constraints, mention frameworks, reference existing code.
