const connectionTest = await callTool("test-connection", {});
// 2. Analyze widget options
const headerWidget = await callTool("get-widget-info", { widget: "header" });
const imageWidget = await callTool("get-widget-info", { widget: "image" });
// 3. Generate Composer access for content creation
const composerAccess = await callTool("get-composer-url", { path: "course-creation" });
// 4. Use analysis data to inform content design decisions
if (headerWidget.special.includes("SCORM")) {
// Consider header widget for LMS integration
}
```
### Development and Testing Workflow
```typescript
// 1. Server health check
const health = await callTool("test-connection", {});
console.log(`Server status: ${health.status}`);
// 2. Widget capability assessment
const widgets = ["text", "image", "header", "list", "gallery", "hotspot"];
const analyses = await Promise.all(
widgets.map(widget => callTool("get-widget-info", { widget }))
);
// 3. Testing environment access
const testingUrl = await callTool("get-composer-url", { path: "integration-test" });
console.log(`Testing URL: ${testingUrl.embedURL}`);
