The comment above it in the file

If you update one of the available triggers, update all of them. It's a lot better for performance to not have scripted triggers within scripted triggers when they're checked as often as these ones are.

What it checks

• the game's own tooltip text · ◦ our reading of the script line · code the script where neither exists

“They” is whatever it runs on (the scope it is called in). The scripted triggers and effects it calls link to their own pages; $PARAMETERS$ stay as written: each call fills them in.
