We use Algorithmics RiskWatch where portfolios are analyzed by VaR over scenarios. Can I say that they are predictions reports? or descriptions reports?

They are neither predictive or descriptive, but proscriptive it is a pre-emptive warning of the worst case scenario, of which you are being given notice to take action to avoid. It is risk management.
