First, to get to the phone screen many companies now use some form of automation to weed out applications. Less words simply means less chance of an automated match against the job description criteria.
Second, never underestimate how lazy the HR screener is. They aren't technical, they aren't ambitious, they're generally borderline incompetent people whose sole marketable skill is that they are pleasant to talk with. If you don't spell out, in detail, that you're a Front-end Developer who uses X, Y, Z tools for N years the screener won't be able to read between the lines.
Quick example... I was in a time crunch so I asked a recruiter to find me a Front-end Dev. She came back and asked for a job description, project brief, culture brief, competitors / no hire list, and salary range. I felt like she was asking the right questions, she seemed smart. A week goes by, "Sorry, no candidates." Oh... Ok, well it's a hot market... we can up the price $5k.
Next week, "Sorry, no candidates." Hmm, that's really odd. She apologized, said she had gotten over 100 resumes, and said, "Nobody has 5 years of HTML / CSS experience listed on their resume." After a brief talk, she fundamentally didn't understand anything past a direct keyword match.
Anyway good and bad recruiters, but you never know when your resume is going to end up in the hands of someone really junior. Better to have everything spelled out. Better to be explicit around what you did with each past job. Generally the posted job description is all the recruiter is going off of to match you, so it's easy to tune your resume to fit.
