If you're 11 or 12

Your list is three things your product does NOT do, even though some people might wish it did.

For example, if your product is a Discord bot that auto-mutes spammers:

1. It does NOT mute users for swearing. (Only for spam.)
2. It does NOT send angry DMs to users it muted.
3. It does NOT save chat history for moderation review.

Each of those is something a friend might say "you should add that." Each one, if added, would make the bot bigger, slower, and harder to ship. By writing them on the list now, you've decided ahead of time what the answer is when a friend asks you in week five.
