What this agent helps you do
A Vercel preview debugging agent reviews failed or suspicious preview deployments and prepares an engineer-ready investigation. It can summarize build status, environment questions, logs, branch context, and verification steps.
When to use this workflow
Use it when previews fail, UI changes behave differently than expected, environment variables are uncertain, or product reviewers cannot validate a branch.
How Vercel gives the agent context
Connect Vercel and scope the task to the project, deployment, branch, preview URL, or timeframe. Ask the agent to keep production-impacting changes behind approval.
Example starter prompt
Investigate this Vercel preview issue. Summarize build or deployment signals, environment concerns, likely causes, verification steps, and any approval-required changes.Suggested workflow steps
The agent gathers deployment context, compares it with expected behavior, ranks hypotheses, and prepares checks for the engineer or reviewer.
Expected handoff
The output should include a debugging summary, likely causes, commands or checks, and validation steps. Pair with GitHub, Sentry, or PostHog for code and product evidence.
