Returns goals for an employee. Use this endpoint to locate goals by title before updating, commenting on, closing, reopening, or deleting them. Use filter=status-inProgress when the user asks for current/active goals, filter=status-completed for completed goals, filter=status-closed for closed goals, and filter=status-all when the user says "all goals", "including closed", or you are resolving a goal by title for a write operation where the status is unknown. If no filter is provided, closed goals are excluded. Results are capped at 50 goals; if a title lookup is ambiguous or absent, do not update or delete a different goal.
