# How Mike Krieger actually uses coding agents

Instagram co-founder, Anthropic Labs

**If you take one thing:** `iOS Claude pings Android Claude`, to port each feature. he keeps an iOS and an Android version of a Labs app in step by having the agent on the iOS side message the agent on the Android side after each change.

## In their words

> Most of my Claude Desktop work these days is in these new-style projects and I've really enjoyed how easy it is to kick off a bunch of work while still having a coordinator Claude responding quickly

> I still reach for Opus 5.5 for most work, but Sonnet 5.5 is a great complement.

> I love its design skills and it's great for building features — I use it to make Artifacts often now.

> Go off and do it. Go plan it. Go execute it. Go verify the work. Double verify the work.
