Lightest-touch editing is a critical quality bar
The best redline edit is the smallest legally sufficient change. Rewriting entire clauses instead of making surgical three-word edits slows deals and increases human review burden—a standard called 'lightest touch' that off-the-shelf AI models typically miss.

Original excerpt
The best edit is usually the smallest one: Every redline you send gets scrutinized by an opposing counsel. If a clause needs three words changed and an agent rewrites the entire clause it will both slow down a deal and create extra work for human reviewers. Lawyers call this taking the "lightest touch," and it's a quality bar that out-of-the-box AI models and agents miss.
