One Job, One Life: live a random working life in China
The maker built a browser game with Claude Code where you draw a job, city and employer in China and live it year by year; Claude wrote every career, and nothing calls an AI at runtime.

The full story
One Job, One Life is a free browser game: you draw a random job card, a specific job, city, employer and seniority in China, such as a county-hospital surgeon or a jianbing street vendor in Tianjin, and live it year by year until retirement, with promotions, offers, decisions and AI arriving in your tasks.
Claude Code built the whole app: a Next.js front end, a seeded simulation engine, the timeline, the end-of-life review and a shareable poster. The writing comes from parallel Claude Code subagents, each taking a batch of occupations, pulling career ladders, pay and AI exposure from the maker's occupation database, and writing each life in Chinese, then English.
Every card passes a build validator, a Monte Carlo run of hundreds of lives, an English check and a gender-wording check. Because everything is written in advance, no AI model is called while playing. The illustrations came from a different image model.
