What is powerplatform-CodeApps?

A setup guide for Power Apps Code Apps, which are custom web applications built with tools such as Vite and connected to Microsoft Power Platform. It covers project setup, SDK integration, data handling, and deployment.

Use it to start a React or Vite Code App, connect Power Platform services, develop with mock data, and prepare the app for deployment.

It gives developers a Power Platform-specific starting path instead of leaving them to infer the required folders, tools, and setup steps.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.

Model	Per session	Once invoked
Fable 5	$0.04310	$0.04310
Opus 5	$0.02155	$0.02155
Sonnet 5	$0.00862	$0.00862

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 yesterday.

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:

Code App project setup (Power Platform-specific)
Power Platform SDK integration
Data management (mock first, then Power Platform connectors)
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

Power Platform environment with Code Apps enabled
Visual Studio Code
Node.js (LTS version)
Power Platform Tools for VS Code

Step 0: Create folders

Create a folder named CodeApps in your development directory
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.
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

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

If you are asked, agree to install create-vite
Accept the default package name AppName by pressing Enter.
If you are asked to select a framework, select React.
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.
