v0 is a development agent, not a documented SKILL.md runtime. It turns natural-language product requests into full-stack projects, runs them in a sandbox, connects them to GitHub and Vercel, and can use integrations or MCP tools. Vercel separately publishes an open skills ecosystem and the skills.sh installer.

Use v0 for the application

v0 is well suited to generating and iterating on interfaces, routes, data flows, and full-stack application code. A v0 Project maps to a Vercel Project, so chats can share deployments, environment variables, integrations, domains, and a GitHub connection. Publishing creates a Vercel deployment with a stable production URL.

That does not mean a SKILL.md dropped into any v0 chat automatically becomes a native skill. Current v0 documentation emphasizes project instructions, sandbox terminal access, marketplace integrations, MCP servers, and pre-installed coding agents. If a skill-enabled agent such as Claude Code runs inside the v0 terminal, that agent’s own discovery rules apply.

Use Vercel for the hosted product boundary

Vercel hosts the static application, server functions, custom domain, secrets, storage, and AI Gateway used by the SkillForge browser product. Production secrets stay in Vercel rather than in the browser or repository. Preview deployments provide a review surface before the Git-connected production branch changes.

Use skills.sh for portable packages

Vercel’s skills CLI installs public Git-hosted packages into more than eighteen agent hosts. That ecosystem is separate from v0 project generation. A SkillForge user can create a portable skill, publish its folder in a public repository, and give users an install command such as npx skills add owner/repo --skill name.

A practical combined workflow

  1. Use SkillForge to describe the reusable job and produce a readable SKILL.md.
  2. Test the skill in the target host with positive, negative, and incomplete-input prompts.
  3. Use v0 when you need a web interface or full-stack product around the workflow.
  4. Connect the project to GitHub and let Vercel create previews and Production.
  5. Keep provider credentials in Vercel and the portable skill in Git.
  6. Publish the skill through a readable repository and skills.sh only after the package is reviewable.

Do not collapse the layers

The model, agent host, skill, MCP tool, application, and deployment platform solve different problems. A model generates output. A host chooses context and tools. A skill supplies procedural knowledge. MCP supplies typed external capabilities. v0 builds the application. Vercel runs it. Clear boundaries make compatibility claims and debugging much easier.

What to verify before launch

Exercise the public domain, account flow, server function, storage path, AI call, downloadable artifact, and mobile layout. A successful v0 preview or Vercel build proves only that the deployment completed. It does not prove that OAuth callbacks, private data boundaries, desktop packages, or downstream skill activation work.
