# Extension Development in Nimbalyst

Nimbalyst provides MCP tools for building, installing, and hot-reloading extensions directly from within the running app. This enables rapid iteration on extension development without manually running build commands.

The recommended in-app scaffold flow uses `File > New Extension Project`, `Developer > New Extension Project`, or the Extension Developer Kit's `/new-extension` command. Enable Extension Dev Tools in Settings > Advanced before using the build/install workflow.

## Available MCP Tools

### Build Extension
```
mcp__nimbalyst-extension-dev__extension_build
```
Runs the project's `build` script (usually vite build) with pnpm if the project uses pnpm, npm otherwise.
