Sounds to me that the tool you are using is being simplistic.
"Implement" as a verb means "to carry out" or "to begin". It is one of those words that writers often use because they want to use a big word rather than a short word to impress their readers with how smart they are because they know all these big words.
I recall once, I wrote a technical manual for a government agency, and I tried to make it as clear and easy to read as possible. Then they sent it to the agency's editors, who made changes like, everywhere I wrote "use" they replaced it with "utilize", to make it sound more pretentious.
So if you started out writing, "Our workers should carry out this plan", and then said to yourself, No, that doesn't sound pompous enough, and went back and changed it to, "The aforementioned personnel should implement this plan" ... don't do that. That's bad writing.
But there's nothing inherently wrong with the word "implement". If you called a portion of your plan, "Our Implementation Strategy", I wouldn't change it to, "Our Carrying-Out Strategy". That would just sound goofy. And if your first draft said, "The only implement available for the job was a large shovel", I certainly wouldn't change that to "The only carry out available for the job ..." (I'm suddenly reminded of the newspaper that instructed a junior editor to replace any occurrence of the word "black" in news stories with "African-American". And so he dutifully corrected a sentence to read, "The city council adopted a new austerity plan to get the budget back into the African-American.")
