Clean

A worldbuilding atlas: paint the regions of an invented world on a vintage school-atlas sheet, draw rivers, roads and sea lanes, place towns, ports and ruins, and get a computed gazetteer with checks for gaps, overlaps and uphill rivers. Then write lore for chosen regions and get trade roads, ports and border disputes proposed as ghosted edits - every claim checked against the map. Built on @danjdewhurst/worldbuilding (lore) and @jwynia/economic-systems (trade).

Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
