What are the meaningful static checks on m scripts and function?

Hi everyone, I am trying to build a code analyzer for m files. I am of course using mlint (checkcode etc). Apart from these I am also checking certain other features such as

code2comment ratio

deprecated function

Valid m file

Function or Script

No Error Messages

User Functions

Function Complexity

File Complexity

undocumented functions

mlint warnings.

Can you people please help me, by suggesting some more checks for this? I am pretty new to programming as such, and some of the checks I have mentioned above might be very trivial, so any suggestion from the experienced users will be mighty helpful to me.
