  • Interface uniformization (e.g when expecting a quanta or measures...string or dictionary always and not string only or double etc)
  • What are the different tools for and where are the functionality ... (3 flagging tools for e.g) are there repetition and unnecessary obscurity.
  • Any rules on how many functions a tool should have v/s few tools with lots of parameters
