See Spec-Driven Development in action across different scenarios with these community-contributed walkthroughs. They are useful read-only examples of completed flows, but they are not official golden outputs for generated specs, plans, or tasks.
Greenfield .NET CLI tool — Builds a Timezone Utility as a .NET single-binary CLI tool from a blank directory, covering the full spec-kit workflow: constitution, specify, plan, tasks, and multi-pass implement using GitHub Copilot agents.
Greenfield Spring Boot + React platform — Builds an LLM performance analytics platform (REST API, graphs, iteration tracking) from scratch using Spring Boot, embedded React, PostgreSQL, and Docker Compose, with a clarify step and a cross-artifact consistency analysis pass included.
Brownfield ASP.NET CMS extension — Extends an existing open-source .NET CMS (CarrotCakeCMS-Core, ~307,000 lines of C#, Razor, SQL, JavaScript, and config files) with two new features — cross-platform Docker Compose infrastructure and a token-authenticated headless REST API — demonstrating how spec-kit fits into existing codebases without prior specs or a constitution.
Brownfield Java runtime extension — Extends an existing open-source Jakarta EE runtime (Piranha, ~420,000 lines of Java, XML, JSP, HTML, and config files across 180 Maven modules) with a password-protected Server Admin Console, demonstrating spec-kit on a large multi-module Java project with no prior specs or constitution.
Brownfield Go / React dashboard demo — Demonstrates spec-kit driven entirely from the terminal using GitHub Copilot CLI. Extends NASA’s open-source Hermes ground support system (Go) with a lightweight React-based web telemetry dashboard, showing that the full constitution → specify → plan → tasks → implement workflow works from the terminal.
Greenfield Spring Boot MVC with a custom preset — Builds a Spring Boot MVC application from scratch using a custom pirate-speak preset, demonstrating how presets can reshape the entire spec-kit experience: specifications become “Voyage Manifests,” plans become “Battle Plans,” and tasks become “Crew Assignments” — all generated in full pirate vernacular without changing any tooling.
Greenfield Spring Boot + React with a custom extension — Walks through the AIDE extension, a community extension that adds an alternative spec-driven workflow to spec-kit with high-level specs (vision) and low-level specs (work items) organized in a 7-step iterative lifecycle: vision → roadmap → progress tracking → work queue → work items → execution → feedback loops. Uses a family trading platform (Spring Boot 4, React 19, PostgreSQL, Docker Compose) as the scenario to illustrate how the extension mechanism lets you plug in a different style of spec-driven development without changing any core tooling — truly utilizing the “Kit” in Spec Kit.
