What Was Deconstruction? Sure. Deconstruction is a process of transcendental philosophy which aims to show, by immanent means, that the conditions of possibility of any identity, system, or claim, are, at one and the same time, the conditions of their impossibility. One of the upshots of this process is to instill an unceasing sense of responsibility upon those who engage or uphold said identities, systems, or claims. This includes truth, to which deconstruction holds us responsible to, denuding us of any ability to disavow such responsibility. It's quite in line with say, the Kantian emancipatory project which of course Derrida claims fidelity to.
Now, I'm still waiting on my textual evidence for the claim about skepticism.
