Skillopt Sleep

This gives your local Claude agent a nightly self-improvement cycle. It reads your past sessions, extracts recurring tasks, replays them offline against a held-out validation set, and only keeps memory or skill edits that measurably improve performance. The whole thing stages proposals first so nothing changes until you explicitly adopt them. Default mode is mock replay with zero API spend, which is enough to see the mechanics work. Switch to a real backend and it burns your API budget to genuinely get better at your specific workflows. If you've ever wanted proof that distilling experience into durable competence actually works, run the bundled experiment script, it shows the held-out score rise and the gate block bad edits.
