Agent Vision — diagrams for the user

Agent Vision is a hosted diagram app. You write a small JSON document (the spec — a DSL), the app renders it (2D now, isometric later), stores every change as an immutable revision, and returns a public share URL plus a rendered PNG so you can show the user immediately.

This installed skill is a thin connection recipe. The full DSL, the color / idiom grammar, worked examples, ops-patch reference, icon catalog, and warning list live in the hosted, canonical skill doc — fetch it once at the start of a diagramming session and follow it:

<app-url>/skill.md   (ask the user for their Agent Vision app URL)

(Replace the host with whatever app URL the user gave you; the skill doc lives at <app-url>/skill.md.)

Connecting (given only the user's app <url>)
