What it does
A unique id that will never be made twice, for reference numbers and keys. It's a value node: no white pins, it works out its answer when a step wired to it needs it. It gives 1 value later steps can use. Find it under Values in the palette.
When to use it
Use it when a step needs a value worked out first: A unique id that will never be made twice, for reference numbers and keys.
When not to
For a value that never changes, type it into the setting instead of wiring a node.
Typical wiring
Sockets: settings you can wire
- Short form Yes / no
-
Only the first 8 characters, easier to read out.
What goes there: Type it in the side panel, or wire in true or false. e.g. true
If it's empty: Optional. Left alone, it's off.

The id. e.g. 3f2b8c1e-5a47-4d2b-9c0e-7a1f1d2e3b4c
If it's empty: Empty when the step didn't make one (it stopped early or was skipped); steps reading it get nothing.
