Ability checks are a mechanic used to resolve uncertainty. They aren't actions in and of themselves.
A hag's Deception check might be used to oppose a character's Wisdom (Insight) check, when the player describes his or her character as trying to discern the hag's truthfulness and the DM says that the character's action has an uncertain outcome (perhaps because the hag has had hundreds of years of lying experience and the character has no clues to go on as yet).
A githzerai monk's Wisdom (Insight) check might oppose a character's Charisma (Deception) check, when the player describes his or her character as trying to deceive the githzerai monk and the DM says that the character's action has an uncertain outcome (perhaps because the githzerai is carefully studying the character's mannerisms and the lie isn't terribly crafty).
An orog's Charisma (Intimidation) check might oppose a character's Charisma (Intimidation) check, when the player describes his or her character as trying to get the goblins to flee the battle and the DM says that the character's action has an uncertain outcome (perhaps because the goblins fear the orog about as much as a group of armed adventurers).
At no point am I using these skills to tell a player what his or her character thinks, how he or she acts, or what he or she says. I'm just using them to resolve uncertainty that exists outside of those things because the player controls the outcome of how a character thinks, acts, or what he or she says in the face of what the DM describes.
