Plethora Keraunos
Three precision layers working in concert.
Direct Win32 API calls via ctypes. Zero subprocess overhead for display, audio, and registry ops. CREATE_NO_WINDOW everywhere.
Tier 1: Sub-millisecond RapidFuzz catalog resolution. Tier 2: SmolLM2-135M offline SLM for complex natural language → strict JSON schema output.
All package ops (WinGet · Chocolatey · Scoop) run invisibly. In-app updater checks GitHub Releases and self-installs — zero popup.
Engineered from ground zero for silent, declarative precision.
