How Vercel built an ecosystem on the open skills standard

Vercel Qa — Read more Vercel is a platform developers use to build and deploy web applications and agents. Its Chief of Software, Andrew Qu, built skills.sh , a registry on top of Anthropic’s open Skills spec, where developers discover and install agent skills. I went through all the phases, sub agents, file systems, and the version we serve today runs on roughly 100 skills: aggregation, customer metrics, product metrics, time series data.

Agent or tool: Claude Code
Topic: Software Development
Reported on: Case study (Anthropic)

Why it matters

Coding agents are moving from autocomplete to doing whole tasks: reading a codebase, making a plan and changing many files. This case is a concrete example of where that works in practice. It is one of 221 sightings filed under Software Development on Agent Sightings (number 76 by interest), and one of 255 involving Claude Code.

How you could try it

Here is a reusable prompt, written by us in our own words, that captures the task. Paste it into Claude Code or any similar agent and adjust the details to your situation.

I want a coding agent to plan first, work on a branch, and show me the diff before anything is merged. The tool in the source case was Claude Code.

Saved

Tip: Work on a fresh branch, ask for a plan before edits, and review the diff and test results before merging.
