What it is
Claude Code plugin that replaces the compaction summary with Jev decisions: every tool call and result is scored in one fast request, stale ones are dropped or truncated, everything kept stays verbatim. Also usable as an npm library.
Getting started
From the README:
npm install fast-jev-compaction
export TYPESAFE_API_KEY=...Where the decision sits
fast-jev-compaction calls the hosted decision API rather than running its own weights. That keeps the project small and means its behaviour moves whenever the vendor ships a new model version. It also means an API key and a network round trip sit in the path of every decision.
Models it references: Jev.

We turn your historical decisions into a frozen test set, then tell you which model, which threshold, and how much of it you can safely automate.
