- Private by construction: photos are copied to public storage only on publish
- EXIF including GPS stripped at the moment of publication
The prompt that built it
This prompt is being written up.
It'll appear here, and in the Vault, once it's published.
How it gets made
Nine parts, in the same order, every time.
Every build on this site comes out of the same structure, whether it is a game, a ledger or a suite of tools. The method is published in full, and so are the prompts I am allowed to publish.

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.
313 production Claude skills
Installed, organised, documented.
The scaffold and the method
How the prompts are structured, so you can write your own.
