Satipatthana is simply being aware of whether defiled or unwise thoughts are arising, and to stop them.
If good thoughts arise one should cultivate those; this part involves cultivating panna.
By the way, what needs to be done is closely associated with the satara Sammappadhäna, which is conventionally translated as “Four Supreme Efforts”, in the 37 Factors of Enlightenment:
1. Prevent immoral qualities that have not yet arisen from arising.
2. Abandon immoral qualities that have arisen.
3. Maintain and cultivate moral qualities that have arisen.
4. Initiate moral qualities that have not yet arisen.
See, “Two Versions of 37 Factors of Enlightenment“.
As always, dasa akusala are the measuring stick. Of course, cultivating wisdom (panna) also involves learning Dhamma concepts like Tilakkhana is included.
So, the only skill needed is determination and knowledge.
