jevex

jvsteiner

721

SDK & Decision Frameworks MIT E2 · source reviewed

An Agent experiment where Jev directs a tool loop, a chat model fills arguments and prose, and MCP tools execute.

JEV · Decision point

Jev selects the next action and approves the concrete call; tool results feed the next state.

Separates decisions, content generation and execution, with author-run comparisons.

jevmetrics

ishantanu

723

CLI & Pipelines Apache-2.0 E1 · source linked

Use it to assess unfamiliar instrumentation, review candidates for reduced retention, and selectively filter metrics before they reach a primary backend. Inference runs asynchronously, and cached assessments let subsequent batches use the same decision without another API 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.

cli-git-gatestyped-decisions

jevrag

ajanm007

724

SDK & Decision Frameworks MIT E2 · source reviewed

Replaces hardcoded RAG thresholds with explicit calibrated decision points. Five primitives (retrieval stopping, chunk splitting, context selection, answer abstention, cache trust) behind one swappable state → Decision → confidence → action interface, each evaluated on real datasets with a calibration harness that reports honestly.

JEV · Decision point

jevrag/decision.py — the `ask(state, questions) -> DecisionResult` method calls `api.typesafe.ai/v1/systemone` via the Jev backend. All five primitives in `jevrag/primitives/` route through this method.

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

Domain & Vertical Tools MIT E2 · source reviewed

An EVM Token screening tool with library, CLI and MCP interfaces for market-feature-based risk judgments.

JEV · Decision point

Uses a deterministic local engine by default; a TypeSafe key enables real Jev judgments over features.

Shows features, decision provenance and scores together for inspection.

JevSeek

morcoan

726

Domain & Vertical Tools MIT E2 · source reviewed

Local coding workspace and agent decoupling tool routing via Jev from detailed argument generation via DeepSeek.

JEV · Decision point

Employs Jev to classify and select the next tool action based on execution state, delegating parameter generation to DeepSeek.

Combines low-latency discrete routing with capable generative modeling, reducing overall prompt overhead and turn latency.

Domain & Vertical Tools E2 · source reviewed

A resume-review app that checks general writing and structure or compares a resume with a specific job description.

JEV · Decision point

Jev evaluates extracted resume text against typed questions; a Worker combines the results into review output.

Records inputs and judgments so individual reviews can be inspected later.

High-Frequency & Simulation MIT E1 · source linked

A check costs from half a cent (a text that dies in the first wave) to ten cents (one that reaches all 10,000), and takes from 3 seconds to a minute. The interface comes in Ukrainian and English, and so do the personas: a text is read by the crowd that speaks its language, 10,000 Ukrainians or 10,000 English speakers, so there is nothing to choose.

JEV · Decision point

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

Data & Search MIT E1 · source linked

Selects source-linked evidence within a token budget using Jev Noul relevance judgments and local diversity-aware selection.

JEV · Decision point

Jev judges whether each passage is useful evidence for the supplied task; local code selects verbatim passages and citations within the token budget.

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