Your coding agent is wasting expensive tokens on decisions a tiny model can make in milliseconds.
Jev + Claude Code is a pretty clever fix.
Think of Jev as the fast gut brain. It handles simple yes/no decisions, classification, and scoring.
Claude is the slow thinking brain. It only steps in when the task needs real reasoning.
here’s how to wire them together:
1. Give Claude Code Jev tools
/plugin marketplace add rashedInt32/jev-mcp
/plugin install jev@jev-mcp
Claude can now use Jev for classify, score, and check.
2. Find the right code without reading everything
npm install -g @dzhng/jev
jevgrep "how are payments retried?" ./my-project
Ask a question about your codebase and get the relevant files back.
The author measured ~30% lower costs on the same tasks.
3. Let your agent delegate automatically
npx skills add altryne/jevify --skill jevify
This teaches your agent to hand repetitive yes/no decisions to Jev instead of burning tokens on Claude.
4. Cut wasted context
fast-jev-compaction replaces Claude Code's usual summary with Jev-based decisions, removing stale tool calls while preserving everything else word for word.
the idea is simple:
stop paying for deep reasoning when a fast, cheap decision is enough.
less wasted inference. lower costs. faster agent runs.
save this for your next Claude Code session.
