Build a full-stack project from scratch in Copilot agent mode

The poster built a full-stack project with Copilot agent mode using Claude 3.7 Sonnet; it needed babysitting through setup problems but eventually produced styled, working React components.

What They Did: The poster used GitHub Copilot agent mode to build a full-stack app from scratch across React, TypeScript, Tailwind, ShadCN/UI, Python, Clojure, and PostgreSQL. Before each run they gave the agent three files: a project spec, a step-by-step task list, and a Copilot instructions file; then they babysat shell commands, corrected bad paths and Windows/Linux CLI mismatches, and kept refining the instructions between runs.
How It Went: Claude 3.7 Sonnet was the most proactive and kept trying to recover from setup errors, but all models initially failed on the React, Tailwind v4, and ShadCN setup. After a second Claude run and better instructions, the poster says they finally got fully styled, working React components.
Worth Knowing: The main catch was setup reliability: the poster says even routine install and directory steps needed repeated manual intervention and instruction-file tweaks.

Try it yourself with GitHub Copilot

Using agent mode, build a full-stack project from scratch: [describe the app] with a [frontend, e.g. React] frontend and a [backend/database] backend. Set up the project structure, get it running locally, and create styled components for [main screens or features]. If setup hits an error, try to fix it yourself first, and stop to ask me before installing anything large or changing config outside the project folder.
