It's documented in the ELisp manual:
 -- Special Form: interactive &optional arg-descriptor &rest modes
 [...]
 The MODES list allows specifying which modes the command is meant
 to be used in. See *note Command Modes:: for more details about
 the effect of specifying MODES, and when to use it.
 -- Macro: declare specs...
 [...]
 ‘(modes MODES)’
 Specify that this command is meant to be applicable only to
 specified MODES. *Note Command Modes::.
See also "Command Modes" in the ELisp manual, which is dedicated to
these features.
