What does "shell introspection" mean?

[Juan Kinunt]

In the PyDev installation documentation you see this sentence:

"The Forced builtin libs are the libraries that are built-in the
interpreter, such as __builtin__, sha, etc or libraries that should
forcefully analyzed through shell introspection (the other option to
analyze modules with too much runtime information is providing
Predefined Completions)."

What does "shell introspection" mean? And what do you think the writer
want to say with "too much runtime information"?
