Basing the information on what has been evaluated seems fragile to me.
I imagine that the tool will work better working from static and
lexical sources, such as the documentation and the program text (which
is accessible via the plug-in tool interface).

Still, through the plug-in tool interface, you can grab the program's
namespace and inspect its bindings through functions like
`namespace-variable-value'.
