Evaluation & Observability MIT source reviewed

Audits Jev calibration, option-wording effects and Korean judgments through public APIs and datasets.

JEV · Decision point

Collects Noul and Choice outputs and compares them with labels for error, accuracy and stability.

Keeps per-call records and experiment notes to qualify conclusions.

jev-clash-royale-test

JanDalhuysen

High-Frequency & Simulation source reviewed

A Clash Royale-style sandbox whose Jev bot decides play-or-hold, card, lane, and depth in one System One call.

JEV · Decision point

One systemOne call with a should_play Noul plus card, lane, and depth Choices.

Makes play choices inspectable probabilities. package.json says ISC; there is no LICENSE file.

jev-decision-gateway

kuldeepsinh19

701

Routing & Cost Optimization MIT source reviewed

A gateway that asks Jev continue / tool / verify questions and invokes a generative LLM only when policy says generation is needed.

JEV · Decision point

TypeSafeClient.systemOne answers policy questions; the adapter then decides whether a generative model runs.

Places expensive generation behind a Jev gate. Author-reported call savings were not retested here.

703

Routing & Cost Optimization source reviewed

A customer-service routing demo that batches Jev questions before following the resulting route.

JEV · Decision point

Assesses classification levels, human-handoff intent and frustration, with low-confidence escalation.

Combines routing and human handoff while leaving response generation to the application.

Evaluation & Observability source reviewed

Maze experiments comparing Jev single-step choices with multi-step lookahead.

JEV · Decision point

Chooses moves from direction candidates, then checks collisions, paths and completion.

Keeps experiment settings and failures visible for studying limitations.

High-Frequency & Simulation source reviewed

Uses Jev to play Chrome Dino and a local shooter arena while Python executes structured decisions.

JEV · Decision point

Chooses jumping, ducking, movement, aim, or firing from game state, with local execution rules.

An inspector lets users compare state, model answers, and executed actions.

games-simulationtyped-decisions

Real-time firewall for AI coding agents: a PreToolUse hook checks every Claude Code / Codex tool call with deterministic shell-aware rules, and unmatched actions go to Jev for a calibrated allow/ask/block that fails closed.
