• If my package is a syntax it doesn't also add a color scheme. ***
• If my package is a syntax it is named after the language it supports (without suffixes like "syntax" or "highlighting").

The bot says:

Packages must be sorted alphabetically (by name)

Also:

• Your command is “clear text”, not “clean text… a typo?
• It’s recommended to prefix the command with the name of the providing package, so users know where it came from (and which settings to change to make it behave differently). E.g. “TextCleaner: clean text”.
• You should expose your settings via the package settings menu, and the command palette.
