In plain words
What is it for?
Use it to start a React or Vite Code App, connect Power Platform services, develop with mock data, and prepare the app for deployment.
Why use it?
It gives developers a Power Platform-specific starting path instead of leaving them to infer the required folders, tools, and setup steps.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is tchinnin/powerplatform-vibecoding-samples's own configuration. It tells GitHub Copilot how to work on powerplatform-vibecoding-samples itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything powerplatform-vibecoding-samples configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is // import { UserService } from '../Services/UserService';.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

powerplatform-CodeApps scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Power Apps Code Apps Development Guide

This guide covers Power Apps Code Apps-specific setup and integration. For general React development, Fluent UI 9 patterns, routing, and UI best practices, refer to React-SPA.instructions.md.

Power Apps Code Apps Workflow:

  1. Code App project setup (Power Platform-specific)
  2. Power Platform SDK integration
  3. Data management (mock first, then Power Platform connectors)
  4. Build and deployment to Power Platform

For React Development: See React-SPA.instructions.md for:

  • Folder structure and organization
  • Fluent UI 9 components and theming
  • React Router implementation
  • Performance optimization
  • Responsive design patterns
  • Accessibility guidelines

1. Code App Project Setup (Official)

Follow these steps to create a complete Power Apps Code App from scratch.

Prerequisites

Step 0: Create folders

  1. Create a folder named CodeApps in your development directory
  2. Inside CodeApps, create a folder named after your app, e.g. AppName
    • AppName will be replaced by the name of the app. Ask the user to provide it.
  3. Inside AppName, create a README.md with the detail of the CodeApp context.
    • Follow the src/README.md template from React-SPA.instructions.md

Step 1: Initialize your Vite App

  1. Open Visual Studio Code and open a new PowerShell terminal and enter:

    npm create vite@latest AppName -- --template react-ts
cd .\CodeApps\AppName
npm install

  2. If you are asked, agree to install create-vite

  3. Accept the default package name AppName by pressing Enter.

  4. If you are asked to select a framework, select React.

  5. If you are asked to select a variant, select TypeScript.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
