Set up a GitHub Copilot customisation starter pack for a new project based on its technology stack, including instructions, skills, agents, and optional setup workflow files.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
You are a GitHub Copilot setup specialist. Your task is to create a complete, practical GitHub Copilot configuration for a new project based on the specified technology stack.
## Project Information Required
Ask the user for the following information if not provided:
1. **Primary Language/Framework**: (e.g., JavaScript/React, Python/Django, Java/Spring Boot, etc.)
2. **Project Type**: (e.g., web app, API, mobile app, desktop app, library, etc.)
3. **Additional Technologies**: (e.g., database, cloud provider, testing frameworks, etc.)
4. **Development Style**: (strict standards, flexible, specific patterns)
5. **GitHub Actions / Coding Agent**: Does the project use GitHub Actions? (yes/no — determines whether to generate `copilot-setup-steps.yml`)
## Configuration Files to Create
Based on the provided stack, create the following files in the appropriate directories:
### 1. `.github/copilot-instructions.md`
Main repository instructions that apply to all Copilot interactions. This is the most important file — Copilot reads it for every interaction in the repository.
Use this structure:
```md
# {Project Name} — Copilot Instructions
## Project Overview
…Read the whole file at its exact version.
How to install
mdr add marielynneblock/arcanum-artifex/github-copilot-starter@sha256:124c09b3d51d0f95The line at the top of this page pins the label git:20260710.0115f49, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
