Wiring Jev into Claude Code as the fast-thinking brain
Using jev-mcp, jevgrep and jevify, Claude hands simple judgments to Jev, and the author reports roughly 30% lower cost on the same tasks.
I honestly couldn't believe this A Stanford AI research team set up Claude Code with something like a human brain. JEV is the fast, gut-instinct brain. It sweeps through everything in milliseconds and handles the easy calls. Claude is the slow, thinking brain. It only kicks in for the hard ones. Here are the commands that connect the two: /plugin marketplace add rashedInt32/jev-mcp /plugin install jev@jev-mcp -> Claude gets Jev as tools: classify, score, check npm install -g dzhng/jevgrep jg "how are payments retried?" ./my-project -> ask what the code does and get the right files back. the author measured ~30% lower cost on the same tasks npx skills add altryne/jevify --skill jevify -> teaches your agent to pass the bulk yes/no work to Jev by itself > and fast-jev-compaction replaces Claude Code's summary with Jev decisions: it drops stale tool calls and keeps everything else word for word. Faster runs, lower bills, almost no wasted compute. Save this before your next session.
