What they did
A builder made a playable 3D cat game in 2 days. Tripo turned his reference images into 16 3D models; Opus 5.5 in Blender made the rigs, animations and room, and in Unity wrote the ray, rope, parachute and cat AI, one short brief per system.
Result (as claimed)
16 models cost $8.20 and 31 Claude Code sessions about $88 at list price; every prompt is in his write-up.
Tools they used
Cost: Claude Code: from $17/mo; Claude Opus 5.5: from $4 in / $20 out per 1M tokens; Tripo: free plan, paid from $20/mo.
Set it up
Write a one-page brief
Describe the app in plain words: who it is for, the 3 core screens or actions, and what "done" looks like.
Start the project with your agent
Open Claude Code and paste the brief. Ask it to propose a stack and a file plan before writing code.
Build one slice at a time
Ship the smallest working flow first, run it, then add features one by one. Commit after each working step.
Test it like a user
Click through on desktop and phone. Ask the agent to add basic tests and fix anything that breaks.
Check security and ship
Keep keys in environment variables, check auth and database rules, then deploy and share the link.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.
