Use Claude Code for a while and you collect a pile of standing instructions: test the payment code, use British spelling, follow the deploy checklist. Showing all of them every time wastes context.
jev-rules asks Jev which rules fit each request and delivers only those. In its demo, a checkout bug report brings in the payments rule and the checkout notes while eleven other rules stay out. A side pane lists every rule and shows which ones Jev picked, with their scores.
