Why it scores highest
Task clarity carries more weight than any other dimension. A model that cannot tell what action to perform will pick one for you — usually the blandest reading. 'Help me with my landing page' could mean write it, audit it, redesign it, or debug its CSS. Four different jobs, one sentence.
How to do it
Lead with one imperative verb and its object: refactor this function, draft this email, classify these tickets. One primary verb, not three — a prompt that asks to 'research, summarise and then design' is three prompts wearing a trenchcoat. Split them.
The test
Read only your first eight words. If someone could carry out the wrong job from them, the verb is missing or buried. Move it to the front.
