GitHub Copilot Can Generate Your Entire App Blueprint (Most Developers Miss This)
GitHub Copilot in VS Code, run in agent mode with Claude as the LLM, analyzing an unfamiliar AL project (a subscription billing app) to produce an app blueprint and a markdown README. Shows the prompt used and the resulting functional areas, features, APIs, reports and business processes.

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.
