How would you make a workflow safe to hand over?

Relative paths, not C:\Users\yourname\. Absolute paths are the commonest reason a workflow fails immediately on someone else's machine.

Non-appending outputs — overwrite or delete-and-append — so a second run does not duplicate the data.

Containers with meaningful names so the stages are readable, and annotations saying why a tool is there rather than what it is.

An exceptions output for rows that failed a join or validation, so problems surface rather than disappearing.

And fill in the workflow properties — name, description, author. It is often the only clue about ownership when something breaks a year later.
