Try it

npx skills add ChanMeng666/archlang

Then ask your coding agent:

Design a one-bedroom flat of about 54 m², with the front door on the north wall.

It writes the plan, compiles it and checks it. This one is 56 lines of text:

A one-bedroom laneway house, compiled from 56 lines of ArchLang. Click to open it in the playground.

_{Click the drawing to open this exact plan in the playground. Change a number and it redraws.}

Why text

Change one number, and one thing moves. Nothing else is redrawn.
The same source gives the same drawing, byte for byte.
An agent can check its own plan without ever looking at an image.

For your agent

This page is all a person needs. Everything else is written for agents: clone the repo and point yours at AGENTS.md, or give it the whole language in one call:
