The Vault

You've seen the apps. Take the prompts.

Anyone can describe an app to an AI and get something back. The difference is in the structure — and the structure is what's written down in here.

Every build prompt on this page

Full text, not summaries. Copy and run.

150 production Claude skills

Installed, organised, documented.

Weekly drops

New prompts and skills, with the reasoning behind them.

Office hours

Bring a build that is stuck. Leave with it working.

The scaffold and the method

How the prompts are structured, so you can write your own.
