Testing GSD: From a Docs-Only Repo to Working Go Code in One Session

Introduction I have been experimenting with Spec-Driven Development for a while now. If you are not familiar with the approach, I have a few articles tagged spec-kit that cover the theory and a real hands-on walkthrough where I built a Go TUI for Apple Container management.

As someone who has used GitHub for years (both for personal projects and corporate needs) I’ve always appreciated the platform’s reliability. However, after a month of putting GitHub Copilot Pro through its paces, I’m genuinely surprised it isn’t even more ubiquitous. If you aren’t a “super heavy” coder but want access to the best tools, this is arguably the highest value-for-money platform in the AI space right now. ...
