Build a mini-app to fulfill the request. Use the apps/ directory and API.openApp(appId, { target: 'tab', title: 'Readable preview title' }) as documented in the Application Environment section.

Workflow

Scaffold — create apps/{appId}/index.html (+ optional styles.css, script.js).
Design for a full browser tab — the preview opens on an internal stagewise://internal/preview/{appId} page, so use responsive layouts that work from narrow to full-width viewports.
Open in tab — call await API.openApp(appId, { target: 'tab', title: 'Readable preview title' }). The title is shown in the tab breadcrumbs. The returned { tabId } can be used with API.sendCDP() if the preview needs inspection.
Iterate — use file tools (multiEdit, overwriteFile) for edits, then call API.openApp(appId, { target: 'tab', title: 'Readable preview title' }) again to open the refreshed preview.

Rules

One index.html per app. Sibling assets resolve via relative paths (./styles.css).
Prefer self-contained HTML (inline or sibling files) — no external build step.
Do not open preview apps in the chat. Use target: 'tab'.
Use API.sendMessage / API.onMessage only when bidirectional communication is needed.
