1.21.2
Minecraft version used when linting literal command() strings
The first lint run downloads Minecraft command data from the network. Dynamic commands such as command(myVar) are skipped because their final text is not known in the editor.
Spyglass
This extension uses Spyglass only for Minecraft command linting inside literal command() strings. It does not register .mcs files as .mcfunction, and it does not enable Spyglass diagnostics across the whole MCS document.
