Failed Vercel build report
Find failed Vercel deployments, pull their logs, and surface the likely cause — every morning.
Every morning, check my Vercel projects for deployments that failed in the last day and help me fix them fast. Find any failed or errored deployments across my projects in the last 24 hours. For each one: - The project, branch/commit, and when it failed. - Pull the deployment logs and quote the actual error (build error, failed check, timeout, etc.). - A one-line likely cause and the first thing to try. Put the most recent production failure first. If nothing failed, just say "No failed deployments in the last 24h" and stop. Read only — don't redeploy.
Failed Vercel builds — 30 Jun 2026 (last 24h) 1 failure docs — main @ a1b2c3d — failed 02:14 Error (build): src/lib/nav.ts:42 — Type 'string | undefined' is not assignable to type 'string' Likely cause: a nav item is missing its `href`. Fix the type or guard the value, then redeploy. No other failures.
A failed production build can sit unnoticed for hours — and when you do spot it, you still have to dig through logs to find out why. This routine checks for failed Vercel deployments every morning, pulls the error straight from the logs, and hands you the likely cause, so the fix starts immediately.
How it works
- It uses Vercel to find failed deployments and read their logs.
- You get the real error and a first-fix suggestion in your inbox, production failures first.
- It's read-only — the routine diagnoses, it never redeploys or changes settings.
Make it yours
- Scope it to production deployments only, or to your most important project.
- Widen the window, or run it twice a day during heavy release periods.
- Pair it with GitHub or Linear so the agent can also open an issue for each failure.
