Many of those skills are obvious gems (item box, teleport, setTemperature(), Debuff immunity, ESP etc.), but then there are those that might nullify anything he would gain from the others (unproductive, useless, one should mean he can never gain skill-levels, and the other than any attempt at using them should backfire). Then there are the wildcards. Shut-in sounds like the job Dungeon Master. NEET sounds like a job that might limit you from becoming a student or employee, but probably has advantages worth the restrictions (otherwise it isnt balanced), sort of like the Hermit class.
Also, TL is pretty scummy, using the wrong image for the series thumbnail to gain clicks. I would have clicked anyway since the title says "isekai", but now I kinda want to drop just out of principle despite the manga seeming ok-ish :/
