WHAT IT DOES

What clear_understanding_cache does on Pypi:best Cad

AI agents call clear_understanding_cache to permanently remove resources in Pypi:best Cad, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why clear_understanding_cache is rated Critical

Clearing caches is an irreversible action that destroys stored semantic, constraint, validation, and view data for the active thread. While caches can theoretically be rebuilt, the act of clearing them is non-undoable and could disrupt ongoing operations or lose intermediate state, placing it in the Destructive category.
