Adamson finished the season fourth in the goalscoring charts with a superb tally of 23, just four behind golden boot winner Chris Scannell - despite missing three months before Christmas with a rib injury.
And the BT engineer, who has been courted by several top clubs, had little studying to do before committing himself for another two years with the Swifts.
"Dungannon have shown a lot of faith in me up to now and this is my way of repaying them for that. There's a renewed belief in the team and I'm already looking forward to next season" said the deadly 26 year old finisher from Newtownabbey.
The Swifts manager is delighted to have secured his top target and will now look for players in supporting roles as he bids to put behind him the last few weeks of survival football and the emotions that come with it.
It's been a busy week for Robinson. Neil McCafferty, initially signed on a short term deal, added two years to his contract on Wednesday, while several of their top names are now available to other clubs.
"It is the most difficult aspect of management but I have to keep the financial end of things right and unfortunately I have had to make several players available to other clubs" said the rookie Swifts manager.
"Aaron Callaghan, Marc McCann and Michael Hegarty are all on the transfer list, while I have released Ryan McCreadie" said Robinson, as one season ended and preparations get under way for the next one to begin.
And the comings and goings at Stangmore Park continue, with the understandably disgruntled second choice goalkeeper, Dwayne Nelson, the latest player on the look-out for a new club after he handed in a transfer request to the club in the middle of last week.
Nelson, a highly-rated U23 international, has been out of favour since January when Barbados international keeper Alvin Rouse was signed up by the later sacked John Cunningham.
