Core takeaway
Ray Amjad embeds Jev in Claude Code's decision loop and logs the token changes on every iteration, showing that moving 80% of routine checks and flow decisions to Jev makes multi-turn coding much cheaper and more responsive.

Key insights
- In long coding tasks, many decisions are simple booleans such as "is the file edit finished" or "did the tests pass";
- Using Jev instead of Claude 3.5 for these intermediate checks avoids having the main model re-read the whole long context;
- The waiting pauses developers notice in the terminal almost disappear.
Gotchas
- Long compiler error stacks need to be trimmed to the core error lines rather than feeding thousands of lines of logs to Jev;
- Transparent interception through a local CLI hook or middleware is recommended.
Overview & result
Ray Amjad puts Jev inside an agentic coding loop with Claude Code and breaks down the exact cost per iteration, showing how to replace 80% of reasoning calls with micro-decisions.
How Jev fits in the loop
- The surrounding agent or application prepares a bounded state and candidate actions.
- Jev performs the iteration gatekeeper decision described by the source.
- Application code executes the selected action and handles low-confidence or exceptional cases.
How to reproduce
- Open the linked source and verify the author, workflow, and claimed Jev role.
- Recreate the smallest bounded decision with your own inputs and credentials.
- Measure accuracy, latency, cost, and fallback behavior before production use.
