Procedure; Human Factors
I was working Ground Control when I heard Clearance Delivery call to Aircraft X; whose flight plan was in front of me. I handed it to Clearance Delivery and listened to their conversation with Aircraft X. There was clearly confusion about the CPDLC clearance upload. I listened to Clearance Delivery explain all details about the TRUKN2 SID with the SYRAH transition. I asked the Clearance Delivery person to have Aircraft X file an ASAP explaining their confusion. The Clearance Delivery Controller told me afterwards the flight was showing direct SYRAH off of the airport. I have seen this before and we have had multiple pilot deviations due to this exact confusion. Review/standardize CPDLC uploads so they work for the pilots.
SFO Ground Controller reported a pilot was confused by the departure clearance received via CPDLC.
