Sonn
Stop repeat mistakes with local reasoning and memory for coding agents
Sonn is a one-line terminal install that adds a persistent reasoning layer to Claude Code. It automatically captures project context, decisions, and boundaries across sessions — then reasons over that history before the agent acts, steering it away from mistakes it was about to repeat rather than retrieving notes after the fact. Everything is local-first: code and memory stay on the developer's machine, and generation runs through their own model credentials. Nothing routes through Sonn's servers.
