**Christian Ledermann Unleashes Spec-Driven AI in Thrilling Buzzword Bingo Test**

*Introduction*
Software engineer Christian Ledermann recently turned a simple party game into a proving ground for next‑generation AI‑assisted development. By building a Django‑backed, HTMX‑enhanced Buzzword Bingo application, he set out to measure how far large language models like Claude and the emerging Speckit framework can push a project when guided only by a tight specification, strict typing, and a battery of modern linting tools. The experiment blends familiar web stacks with cutting‑edge type‑checking and formatting utilities—ty, zuban, pyrefly, and an aggressively configured ruff—to see whether specification‑driven workflows can reduce boilerplate while preserving reliability.

*Key Developments*
The core of the test lies in the specification document that outlines every UI interaction, data model, and endpoint behavior before a single line of code is written. Ledermann fed this spec into Claude, prompting the model to generate skeleton Django views, HTMX templates, and corresponding unit tests. Speckit then took over, refining the generated snippets with type annotations that satisfy ty and zuban’s static analysis. Throughout
