I want to add a description for each function about what it expects on the stack and what it leaves on the stack, not sure how to do that.

You could list the directory and use stack diagrams in comments:

Code:

DIR
  B\->2s @ (B -- 2s)
    \<< B\->R DUP Max2s
      IF >
      THEN 2 RCWS ^ -
      END
    \>>
  Max2s @ ( -- Max2s)
    \<< 2 RCWS 1 - ^ 1 -
    \>>
END

However, the stack diagrams seem superfluous to me in this case.
By using trigraphs I can copy and paste the code into an emulator.

It may only be me, but examples are often helpful.

Examples

16 STWS

Max2s

32767

# 7d
+/-

# 65529d

B→2s
