While the game’s official Creation Kit and Papyrus scripting language allow for significant modifications, they operate within a "sandbox" defined by Bethesda. SKSE smashes that sandbox open. What is SKSE? At its core, SKSE is a utility program that modders (and consequently, players) run alongside Skyrim. Its sole purpose is to expand the scripting capabilities of the game. It does this by bypassing the hard-coded limits of Skyrim’s original engine, allowing mods to access functions, variables, and events that Bethesda never exposed to the public.
Without SKSE, a mod can only ask: "Is the player in city X?"
