You can scaffold a GSD extension by automating the creation of a feature-ready TypeScript skeleton that wires up tools, commands, hooks, and UI stubs. This generates a structured extension with best-practice patterns for state and testability.

Building a GSD extension is the best way to add a custom tool or slash command. It provides a structured skeleton that registers commands and tools the LLM can call, complete with safety checks and rendering patterns.

To hook into GSD events, you create an extension module that registers event hooks. The scaffold wires up these hooks, allowing you to modify GSD behavior and implement custom workflows across project-local or global spaces.

Yes, GSD extensions support creating custom TUI components. The scaffolding process includes UI stubs and best-practice rendering patterns to help you build and integrate custom interfaces directly into GSD.

To validate and hot reload a GSD extension during development, run the /reload command after asking the AI to scaffold or iterate on your extension. This enables an end-to-end workflow from creation to testing.

No manual state setup is needed. The scaffolded GSD extension implements a structured skeleton with best-practice patterns for state management, safety checks, and testability out of the box.
