Gives a "go"

OKS

Think of what someone might say twice to signal approval or permission.

"Gives a 'go'" is a playful way to hint at something that signals approval or permission. The answer "OKS" fits because "OK" is a common way to say "yes" or "go ahead," and the plural form "OKS" suggests multiple instances of giving the green light. It’s a straightforward clue where the wordplay lies in interpreting "go" as approval rather than movement.
