Source Summary

With **Vercel CLI 59.16.0 or later**, eligible static artifacts can deploy in **under one second**. Vercel detects them, skips the build, and returns a live URL.

Practical Implication

Use `vercel deploy` as a lightweight publishing step for agent-generated prototypes, HTML reports, and previews when a full application build would add needless delay.

Use `vercel deploy` as a lightweight publishing step for agent-generated prototypes, HTML reports, and previews when a full application build would add needless delay.

Instant deployment is limited to **10 HTML or Markdown files**, **5 MB total**, and `.html`, `.htm`, or `.md` files. Anything outside those bounds follows a different path.
Connected Context · Feed7 Judgment

This narrows agent-to-preview delivery to an exceptionally lightweight path when the output is a small static HTML or Markdown artifact. It complements broader cloud-agent and deployment workflows by removing an unnecessary build, but only within strict file-count, format, and size limits; it is not a faster general application deployment path.
