Spec Kit guide: write the spec first, then let an AI Agent code

On October 3, 2026, Golem.de published a hands-on guide to Spec Kit, written by Stefanie Schmidt, that walks through what the outlet calls a spec-driven workflow. The central idea, as the piece describes it, is to separate the what from the how: the user first writes down what should be built as a specification, and an AI agent then works from that specification to generate a plan, tasks, and code. The article frames this as a chain that runs from the spec through plan and tasks to the code itself, and it lays out the steps for following that chain in practice.

To see how well the approach holds up, the author used it to build a pizza app and documented the attempt alongside the step-by-step instructions. The guide is filed under software development and open source.

As of this report, the available information on Spec Kit comes from this single hands-on guide. It covers how the workflow is meant to run, the individual steps involved, and the result of building the pizza app with it. The material offers no further quantitative figures that could be checked, and there are no other sources with which to compare the account.
