What you call guidance includes explicitly stating that a DM can call for a check.No, they include guidance for what subset of ability checks they are applicable to.
How is this relevant, given we are considering skills as a game element? We should be looking at the skill RAW. In exactly the same way that the spells system might not include exceptions to PHB 185, but individual spells can.The chapter on Using Ability Scores, under the heading Ability Checks says:
An ability check tests a character's or monster's innate talent and training in an effort to overcome a challenge. The DM calls for an ability check when a character or monster attempts an action (other than an attack) that has a chance of failure. When the outcome is uncertain, the dice determine the results.
Further on in the chapter, under the heading Skills, says:
A skill represents a specific aspect of an ability score, and an individual's proficiency in a skill demonstrates a focus on that aspect. (A character's starting skill proficiencies are determined at character creation, and a monster's skill proficiencies appear in the monster's stat block.)
Why are you focused on stealth checks? I am talking about stealth as a game element. Do you believe stealth isn't a game element?Here we see that skills merely represent proficiency at a subset of ability checks. There is no such thing as a “stealth check,” a character who is proficient in stealth is simply “particularly good at Dexterity checks related to sneaking and hiding,” and so can add their proficiency bonus to the roll when called upon by the DM to make such a check. This is why it’s written out as “Dexterity (Stealth) check” instead of just “Stealth check,” because the character is still making a Dexterity check, just one to which a character who is proficient in Stealth can add their proficiency bonus.
Possibly you don't mean everything you say here? If you do, then where the DM controls the NPC or monster, the DM makes the check.So, “a Charisma check might arise when [a character or monster tries] to influence or entertain others, when [a character or monster tries] to make an impression or tell a convincing lie, or when [a character or monster is] navigating a tricky social situation,” “(other than an attack) that has a chance of failure. When the outcome is uncertain,” the DM should call for a Charisma check. If the action involves “[the character or monster attempting] to influence someone through overt threats, hostile actions, and physical violence, the DM might ask [the player controlling the character or monster] to make a Charisma (Intimidation) check,” which would allow them to add the character’s proficiency bonus to the Charisma check.
