What term describes a person who is not straightforward and is considered crafty?

The term that accurately describes a person who is not straightforward and is considered crafty is "disingenuous." This word refers to someone who is insincere or deceitful, often suggesting a lack of honesty in their intentions or statements. A disingenuous person might present themselves in a way that is misleading, using charm or cleverness to manipulate a situation to their advantage.

In contrast, the other terms have distinct meanings: "discerning" refers to someone who shows good judgment; "dissident" describes a person who opposes official policy or authority, especially in a political context; and "disruptive" pertains to causing or tending to cause disruption or disturbance. None of these terms imply craftiness or a lack of straightforwardness in the same way that "disingenuous" does.
