This issue collects and organizes ideas about built-in rules in the LaTeX linter.

Any built-in rules must be able to be disabled by the user.

• Empty sections
  Trigger if \section is immediately followed by another section command, i.e. without text in between.

  \section{A}
  % This should be avoided!
  \subsection{AB}

• Absence of groups/options
  Trigger if a capture group is missing from a control sequence or environment. For example, a missing [!ht] from a float environment, if that's a preference.
