What they did
A dad makes custom homebrew GBA games for his son. The son plays, says what is fun and what is boring, and he has the model change the game. It was built in Claude first, and now a Grok Bot is building a fork.
Result (as claimed)
His son play-tests every version and shapes the game.
Tools they used
Cost: Grok Bot: from $30/mo.
Set it up
Define the job
Say exactly what you want done and what the agent may and may not do on your behalf.
Share only what is needed
Give Claude the minimum files or access required. Avoid sharing passwords in chat when a safer login flow exists.
Review the plan
Ask the agent to show its plan or draft before it acts, and approve each step that has real consequences.
Check the result
Confirm the outcome yourself (order placed, request sent, document understood) and keep a record.
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.
