Rule Definition
There is no dispute that these comments contribute to a developer's understanding and help a developer write reliable applications more quickly. Without documenting parameters it is dififcult for anyone else than the author to guess the purpose of the parameter except by looking at the code that is using it.

Remediation
Add a @param with a description for each method parameters.
