Know before you use it
The repository and official registry are open source; this describes upstream source, not a guarantee that every linked community item is free.
Source-level research. Confirm the exact item’s terms and compatibility before installing or redistributing.
Direction for your agent
Read components.json and the target registry item before coding; copy exact files and dependencies instead of recreating the component.
Registry index
Inspect registry JSONRead the registry to select an individual item. This index URL is not itself an installation command.
