## Why Included

Vercel CLI can return a live URL in under a second for small static artifacts, making agent-generated reports and prototypes easier to share without a build step.

## 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.

## Agent-Ready Context

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.

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 across 807 accumulated Signals:

This turns deployment into a near-immediate handoff for very small static agent outputs, useful for sharing prototypes and reports without provisioning a full build path. Its strict file-count, format, and size limits keep it a narrow publishing primitive rather than a general replacement for preview or application deployments.

- [Vercel MCP can now deploy code](https://feed7.dev/p/vercel-mcp-can-now-deploy-code-1292qsq) — The MCP deployment capability closes delivery from agent workflows broadly; the CLI artifact path supplies a faster, tightly constrained route when the output is only small HTML or Markdown.
- [Realtime multiplayer, automation, and you! — Idan Gazit, GitHub](https://feed7.dev/p/realtime-multiplayer-automation-and-you-idan-gazit-github-185bstd) — GitHub Next’s use of Markdown as a reviewable workflow boundary gains a lightweight publication option when the resulting artifact fits the static-deployment limits.
- [How Sandstone grew 40x in 147 days on Vercel](https://feed7.dev/p/how-sandstone-grew-40x-in-147-days-on-vercel-1bhjz28) — Sandstone’s preview-based multi-app deployment pattern shows the production infrastructure still needed once an artifact exceeds this small static handoff.
