What the checker looks for

It first works out what kind of request you are making, then checks for the details that kind of request needs.

• Coding: the language, what happens and what you expected, the relevant code, and your limits.
• Writing: the audience or tone, the goal, the format, and your situation.
• Business: the market, the target customer, the numbers, and the format.
• Research: sources, a time period, the scope, and the format.
• Learning: what you already know, a request for an example, and the format.
• Anything else: your situation, the format, and your limits.

What the score means

Under 45 is vague, 45 to 69 is okay, and 70 or more is strong. Longer prompts earn a little more, but only up to about 25 words, because details matter more than length.

The score is a checklist, not a judge. It uses fixed rules in English, so a high score means the usual details are there, not that the prompt will get a great answer.
