High-Frequency & Simulation MIT source reviewed

Observable browser stealth game where Jev makes typed guard judgments while deterministic code owns the physics world.

JEV · Decision point

Queries Jev during gameplay ticks or events to determine guard alert states, feeding discrete decisions back into the game loop.

Demonstrates using Jev for game AI behavior trees, achieving dynamic situational awareness within deterministic constraints.

games-simulationtyped-decisionsai-game

`probabilities` is keyed by your schema's values, not Jev's internal labels, so a score of `1`–`5` reads as `"1"`–`"5"` and not `"0"`–`"4"`. Noul questions carry no confidence of their own, so `confidence` is `None` for booleans and numbers.

JEV · Decision point

Jev returns a structured decision for the local program; consult the source for the exact decision policy.

Adds structured choices or scores to the workflow; performance and cost benefits have not been independently verified.

High-Frequency & Simulation MIT source reviewed

Uses Jev to chain predefined skills for English-language goals in a ManiSkill robot-arm simulation.

JEV · Decision point

Chooses a skill and target from privileged object and gripper state and about thirty primitives.

Separates skill selection from Python motor control.

Security & Guardrails MIT

Jev is a decision model: it answers a typed question with a calibrated probability rather than prose. This action asks it one yes/no question per thing worth being sure about — answered in parallel in a single call — and approves only when every one of them clears your threshold:

High-Frequency & Simulation source reviewed

A RuneBench extension using Jev and a bounded rs-sdk action catalog for RuneScape tasks.

JEV · Decision point

Chooses goal actions, tick interventions and the next polling interval from game state.

Provides action-distribution views, run logs and burst or tick control modes.

Context GC & Filter MIT source reviewed

An Oh My Pi extension that prunes tool history verbatim and reuses decisions to limit prefix rewrites.

JEV · Decision point

Jev judges tool-call and output utility; the extension truncates selected content with recovery notes.

Remembers pruning decisions and reapplies them across requests.

Context GC & Filter MIT source reviewed

A Pi extension that prunes stale tool history verbatim and falls back to Pi summary compaction when needed.

JEV · Decision point

Judges whether calls and outputs should survive in the context sent to the model.

Retains the original session file and records pruning decisions.

SDK & Decision Frameworks MIT source reviewed

A Pi configuration and extension bundle with an optional Jev advisor for capabilities and workflow checks.

JEV · Decision point

Jev evaluates candidate capabilities, outputs and task state; per-feature switches control applying or recording advice.

Advisor failures return to the original path rather than guaranteeing better parameters or lower costs.

SDK & Decision Frameworks MIT source reviewed

A TypeScript decision-to-action harness connecting evidence, Jev judgments, permitted actions, and outcome records.

JEV · Decision point

Submits typed questions, validates answers, and lets domain rules choose registered tools with permission and argument checks.

Keeps local traces of judgments, tool calls, and outcomes.
