Split app-building work across cheaper and stronger agents
A developer had Claude Code take an iOS app to a working build and a company site through to launch in a week, using about 30% of his weekly limit.

What they did
A developer used Claude Code to take an iOS app from design to a working build and his company site from mockup to launch. A main agent on the strongest model planned and ran builds. Cheaper helper agents searched code, built single tickets, did layout work and reviewed code. Rules lived in one instructions file.
How it went
He says both projects used only about 30% of his weekly limit, when he expected to hit the cap. He stresses the app isn't launched, so this says nothing about product quality.
Worth knowing
Helper agents write code but never build; only the main agent runs builds, one at a time, to keep long build logs out of every agent's memory. Helpers are short, one-shot runs.
Try it yourself with Claude Code
Help me set up Claude Code for [my project] with a main agent and helper agents. The main agent plans, splits work into small tickets, runs every build and reviews before committing. Create helpers: a read-only code searcher on a cheap model, an implementer that handles one ticket per run, a designer for layout work, and a reviewer that never edits. Helpers must not run builds. Write these rules into CLAUDE.md. Show me the plan and the file before making any commits.Swap the highlighted [parts] for your own details.
