Build or audit a body of work to rigorous, present-day correctness: ground in the live code, verify every external assumption at the source, and eliminate or never introduce anything broken, obsolete, duplicated, incoherent, or worked-around. Runs whole-repo when invoked bare, or appended to a specific task or focus (a feature, fix, subsystem, surface, or file set), where it holds that task and everything in its blast radius to the same standard so the work is done right in one pass rather than patched and audited later. This skill is strictly manual and must only be invoked by name. When invoked, load this skill and follow it for deep, whole-product correctness, cleanliness, and coherence work across backend, data, APIs, protocols, frontend, UI, UX, copy, configuration, environment contracts, integration points, and product flows, or for self-critical building and rewrites validated against up-to-date, authoritative references.
