Change the API and every consumer at once
api/ → update endpoint schema
web/ → update fetch calls + types
mobile/ → update SDK bindings
The problem
You rename a field in your API. Now the web client, the mobile app, and two internal services all need matching updates. You do them one repo at a time, hoping you remember every call site. You don't. Something breaks in staging. You trace it back to a missed consumer that still references the old schema.
With Agent Grids
Set up a grid with one tile per repo. Give each agent the same context: “The user.email field is now user.emailAddress. Update all references.” Watch the changes propagate across every codebase simultaneously. Review the diffs together before committing anything.
Visibility
See every repo's changes on one screen. Catch mismatches before they hit CI.
Speed
Agents work in parallel across repos. A change that takes an hour sequentially takes minutes.
Confidence
Review all related diffs together. Commit when you're sure the full set is consistent.
Coordinate with confidence
Free tier includes two terminals and one workspace. Lifetime early access for $29 gives you unlimited everything.
