Debug a Vercel App From Logs to Fix
For the production bug at 6pm. DuckyHelper pulls the runtime logs through Vercel's own API, reproduces the bug in its own browser tab with its own cursor, finds the code in GitHub, and opens a pull request you can review.
“Signups are failing in production. Check the Vercel logs, reproduce it, and open a PR with a fix.”

Nothing to send, so it runs straight through.
Nothing in this job sends a message or pays for anything, so it works through to the end and tells you when it's done. If a step ever would, it's built to stop and ask you first.
If it hits a sign-in, you sign in yourself. It's built not to type your passwords or card numbers.
Before you ask it.
What do I say?
Press fn (Ctrl+Shift+Space on Windows and Linux) and ask out loud, in your own words, like "Signups are failing in production. Check the Vercel logs, reproduce it, and open a PR with a fix."
Why is the second time faster?
The first time, it writes small JavaScript tools for Vercel, GitHub and Supabase and builds an API from each site's own buttons, forms and requests. After that it calls them directly, so the job runs in one go instead of click by click. It costs less and breaks less.
Will it send anything without me?
It's built to ask first before it sends a message or pays for anything, and to wait for your yes. It may not recognize every send or payment, so keep an eye on tasks that involve messages or money. It's built not to type your passwords or card numbers: you sign in yourself, and it picks up from there.
Why not just do it by hand?
Debugging production means logs in one tab, the app in another, the code in a third, and keeping it all in your head.
Can I use this today?
