# GitHub Copilot Can Generate Your Entire App Blueprint (Most Developers Miss This)

## Overview

The video starts with basic GitHub Copilot use in VS Code for AL development: inline suggestions, the chat interface, refactoring help and creating smaller objects such as tables and pages. It then moves to a different use: understanding a project you did not write.

The presenter loads a subscription billing app, uses agent mode with Claude as the LLM, and gives a prompt that casts Copilot as a functional consultant creating the blueprint for the app. Copilot returns functional areas, core features, user actions, APIs, reports and business processes. The presenter then has it convert the analysis into a markdown README that can be committed to a GitHub or DevOps repository.

## Key points

- Inline suggestions can be enabled in VS Code preferences by searching for 'next edit' and 'next suggestions'.
- The Copilot chat can be opened with a keyboard shortcut or from the menu.
- Project analysis was run in agent mode with Claude as the LLM on the loaded AL project.
- The prompt used: 'You are a functional consultant in charge with creating the blueprint for subscription billing app'.
- The generated blueprint covered functional areas, features, pages, actions, APIs, reports and business processes.
- Copilot converted the analysis into a markdown README that can be pushed to GitHub or DevOps as documentation.
