refactor: simplify action function signatures (#1083)

This change reduces the interfaces by removing
obsolete parameters from functions.
Obsolete parameters does not means unused ones, but
parameters which could be retrieved from other parameters
instead.

This should simplify logic and maintainability for these
functions.
