Vercel CI: build checks that agents can set up and read

Vercel launched Vercel CI in beta on all plans: automated build and test runs that skip anything a change didn't affect (Vercel claims two to six times faster in its own use). Agents can set it up through a skill and read the results through MCP or the command line. Chris Tate (@ctatedev) calls it 'CI for agents'.

Why it mattersIt closes the loop: the agent writes code, the checks run, and the agent reads the result and fixes it without you in the middle. A cheap win if you already host on Vercel.

How we knowCompany figures are labelled as their own claims; anything we couldn't verify is labelled as a report or a claim.
