Question

A backend team wants every developer to be able to trigger a consistent, reusable Copilot Chat prompt that generates a REST endpoint following their internal conventions (naming, error format, logging). They want this prompt versioned in the repository so it stays in sync with their standards and can be invoked directly from the Chat input in VS Code. Which Copilot feature should they use?

Accepted Answer

Create a reusable prompt file (.github/prompts/*.prompt.md) committed to the repository and invoke it with the / prompt picker in Chat

Answer

Add the conventions to their personal Copilot custom instructions in VS Code user settings

Answer

Configure an MCP server that returns the endpoint template on demand

Answer

Write the prompt in a Copilot Space and ask each developer to copy it into Chat manually
