Interrogator

What it does

Digs out the things you have stopped questioning, then checks the ones where being wrong would actually change what you do next rather than fact-checking everything equally. It runs when you ask it to, rather than on a timer.

Before you install

Open the share link and read the instructions it carries before you add it. @liam_fallen shared this one publicly, and adding it copies the setup into your own account rather than giving you access to theirs.
