The macro call <<dnd.ability {{!!dnd.creature.str}}>> passes the literal string
"{{!!dnd.creature.str}}” as the parameter to the macro, rather than evaluating
it.
There’s a more flexible underlying syntax for calling macros where the
parameters are evaluated before invocation:
<$macrocall $name="dnd.ability" paramName={{!!dnd.creature.str}}/>
Where “paramName” is the name of the parameter to your macro.

Pasting [[23]add[19]] is interpreted as a link to a tiddler titled “23]add[19”
because filter expressions are only evaluated in certain contexts, notably
triple curly braces. Try:
{{{ [[23]add[19]] }}}
