This exercise does not grade you and does not accept caring about your team as evidence. It works from occasions.

You don't need ChatGPT Plus. The free version is fine.
Not the policy, and not what you would like to have done. What you actually did, and what the person went home thinking.
Count the promotions. It is the least sentimental measure of a manager there is.
What you'll explore
A note from Mark

The question is not whether you are a good manager. It is what it is like to be managed by you, and only one of those has an answer you can get at from the inside.
I would start with mistakes, because nothing reveals a manager faster. Not the policy. The first ten minutes. Whether the reaction is to find out what happened or to find out who did it, and whether anybody now hides small problems until they are large ones. That single pattern tells you most of what you need to know.
Then I would count. Promotions, moves, people who took on more, people who left for something better. Two years is enough to see it. Good people grow around good managers and it shows up in the record whatever anybody says in a survey.
And there is always an outstanding conversation. Everybody has one, and how long it has been outstanding is the finding, not the fact that it exists. The costs of avoiding it are being paid by somebody, usually the rest of the team, and they can see exactly what is happening.

What now?
01 · Save it
What the evidence shows about how you manage.
02 · Test it
Ask one person what would make their job easier and do not defend anything they say.
What I would do
Work from occasions. Nothing else is evidence.
Notice the difference between what you intend and what people experience.
Count the promotions. It is the least sentimental measure there is.
Look at what happens in the first ten minutes after a mistake.
Ask somebody. Actually ask them, and then be quiet.
Test it
What did you do in the first ten minutes after the last mistake?
Could each person tell you what good looks like this quarter?
Who has been promoted or moved on in the last two years?
The alternative
The expected question is whether you are any good. Two alternatives usually produce more. The problem may not be harshness but vagueness. Managers who are widely liked and never quite clear leave people anxious in a way that is much harder to detect than being difficult, because nobody complains about a nice manager. Or the issue may be under management rather than over control, where autonomy has been given to somebody who needed direction and is quietly drowning in it. And there is the case where the evidence is genuinely good and the user is anxious rather than deficient, which is a real finding and should be stated as one.

The original research on psychological safety, which began with the finding that better teams reported more errors rather than fewer. Read it before using the phrase.

Marcus Buckingham and Ashley Goodall
An argument that most feedback tells the recipient more about the giver than about themselves. Contested, and a useful corrective if you pride yourself on being direct.
Book
Adam Grant
Grant's finding that givers occupy both the top and the bottom of most performance distributions is the practical heart of this. What separates them is not generosity but whether the giving is bounded. If you have ever concluded that you should do more while quietly running out of road, read this before you add anything.
