What it does
A list of what is costing you money or slowing your Vercel app, found from real production numbers instead of guesses, with a fix for each. The skill first collects metrics, usage and contract data with the Vercel command line tool and saves them to a signals file. A script then decides what is worth looking into, such as a slow route or an expensive function. js strongest. It needs the Vercel CLI, a login, a linked project and Node. Route-level detail needs the Observability Plus plan. It never asks you to paste secret keys into commands.
