Security & Guardrails MIT E2 · source reviewed

Open-source Pi coding-agent extension that uses Jev to check tool calls before they run, scan files for prompt injection, flag risky replies, and keep secrets out of what it sends.

JEV · Decision point

Before each tool call, Jev receives the user's request (or pinned task), the proposed command, the agent's explanation, and recent conversation. It answers a Choice for intent (on task / off task / injected / needs more context) and a Score for risk (safe / needs approval / harmful). Local code turns these into run, ask the user, or warn. If Jev says more context would help, the extension adds it and asks again.

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

Browser & OS Action MIT E2 · source reviewed

An MCP server and skill adding Jev decisions to Aside browser Agents.

JEV · Decision point

The Agent supplies action candidates; Jev picks an ID, then the Agent executes and verifies it through Aside.

High-Frequency & Simulation E1 · source linked

This project evaluates a fixed model. It records rewards and decisions without training or updating model weights. A seeded random policy provides a local baseline.

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.

Security & Guardrails MIT E1 · source linked

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:

Routing & Cost Optimization MIT E1 · source linked

Cost-aware LLM router that picks the cheapest model capable of handling a query, using TypeSafe's Jev for fast classification instead of an LLM call.

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.

Classification & Taxonomy MIT E2 · source reviewed

A hierarchical selector that asks Jev to traverse branches when a catalog has too many options for one question.

JEV · Decision point

Selects one branch at each level and continues until it reaches a final candidate.

Returns the selected path without silently truncating the tail of a large catalog.
