vercel-deployment
Deploy Next.js Apps to Vercel
Vercel deployments can fail because environment settings, runtimes, and build behavior differ across stages. This skill guides Claude, Codex, and Claude Code through practical Next.js deployment decisions.

Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "vercel-deployment" from https://skillstore.io/skills/sickn33-vercel-deployment.md and its manifest at https://skillstore.io/api/skills/sickn33-vercel-deployment/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "vercel-deployment". I need a checklist before shipping a Next.js app on Vercel.
Expected outcome:
- Confirm production and preview environment variables are separate.
- Verify no secrets use a public browser prefix.
- Test preview deployments against non-production services.
- Review function size, timeout behavior, and caching policy.
Using "vercel-deployment". My API route is slow after deployment.
Expected outcome:
The skill would compare runtime choice, bundle size, cold start behavior, timeout limits, and any dependencies that block Edge Runtime use.
Using "vercel-deployment". Should preview deploys use my production database?
Expected outcome:
The skill would recommend a separate preview database or isolated test data to reduce accidental production changes.
Security Audit
SafeThe static findings are false positives caused by Markdown backticks and ordinary Vercel deployment terminology. I found no prompt injection, data exfiltration intent, or instructions that ask the agent to perform unsafe actions.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Prepare a Production Launch
Plan environment variables, preview deployments, and runtime choices before moving a Next.js app to production.
Review Deployment Risk
Check whether previews, databases, caching, and public variables are configured safely for a release.
Troubleshoot Slow Functions
Analyze cold starts, bundle size, and runtime selection when Vercel functions behave poorly.
Try These Prompts
Help me prepare a Next.js app for Vercel. Cover environments, previews, build settings, and common launch mistakes.
Review my planned Vercel environment variables. Identify which values are public, private, build-time, or runtime values.
Compare Edge Runtime and Serverless Functions for my Next.js API routes. Include latency, Node.js support, and timeout tradeoffs.
Help me diagnose a Vercel deployment failure. Ask for missing context, then check build output, environment scope, caching, and runtime limits.
Best Practices
- Separate development, preview, and production environment variables.
- Use preview deployments to test changes before production promotion.
- Choose Edge or Serverless runtimes based on API needs and platform limits.
Avoid
- Putting secrets in variables exposed to browser code.
- Pointing preview deployments at the production database.
- Ignoring build cache, bundle size, and cold start behavior.
