These short, practical patterns show how you can shape GitHub Copilot’s responses by adjusting the context you provide.
Each “recipe” helps Copilot think, reason, and respond more effectively inside Chat, Edit Mode, or Agent Mode.
Today’s recipe, the Persona Pattern, a simple way to give Copilot a role or perspective so its answers feel more relevant, specialized, and consistent.
1️⃣ Developer Persona
Give Copilot a developer mindset.
Act as a senior JavaScript developer. Refactor this function for readability and performance.
Best for: Cleanups, modernizing syntax, and improving code quality.
2️⃣ Reviewer Persona
Have Copilot take the role of a peer reviewer.
Act as a code reviewer. Check this function for edge cases and maintainability.
Best for: Catching potential issues before review.
3️⃣ Tester Persona
Prompt Copilot to think like a tester.
Act as a QA engineer. Suggest Playwright tests to verify the login flow.
Best for: Generating test coverage quickly and spotting missing cases.
4️⃣ Documentation Persona
Use this role when you need explanations or teaching examples.
Act as a technical writer. Explain how this API method works with example usage.
Best for: Documentation, onboarding, and training material.
If Copilot’s tone or answers start feeling repetitive, switch personas.
A security analyst sees your code differently than a performance engineer, and those shifts can change everything.
The Persona Pattern is your way to guide GitHub Copilot to think from the right point of view.
The clearer the role, the sharper the response.
