paper-radar-jev

LYchoon

CLI & Pipelines MIT E2 · source reviewed

An automated research paper radar that fetches the latest papers from arXiv, evaluates their relevance to a configurable research profile using TypeSafe AI, and ranks them by relevance score. Designed for personalized, daily literature discovery across different research domains.

JEV · Decision point

Per paper, Jev answers the overall relevance Noul and configured dimensions together; code applies display thresholds while retaining every successful evaluation.

Separates a short reading list from the complete evaluation archive, with failed items remaining retryable.

Context GC & Filter MIT E2 · source reviewed

Extractive context compaction for Pi that keeps selected original tool records instead of generating a summary.

JEV · Decision point

Jev judges complete read-only tool pairs; local code removes those rated unnecessary.

Preserves original evidence and Pi’s recent-message boundary.

Context GC & Filter MIT E1 · source linked

Jev decides what to keep. Compaction never rewrites the transcript.

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.

Browser & OS Action MIT E1 · source linked

This tool provides a Node CLI for goal-driven web E2E testing where Jev chooses the next step from a code-generated action space, playwright-cli observes and executes browser actions, and code controls inputs, deterministic assertions, and the final verdict.

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.

pr-sieve

Thestral12

1160

CLI & Pipelines MIT E2 · source reviewed

A GitHub Action that compiles `.jev.yml` rules into Jev questions and fails, comments, or passes from the numbers.

JEV · Decision point

Rules become at most twelve questions (`MAX_JEV_QUESTIONS` in src/types.ts). AKIA and private-key armor from src/redact.ts fail locally in src/pipeline.ts with no Jev call.

Does not write reviews, suggest patches, or approve. Policy is read from the base-ref config.

SDK & Decision Frameworks MIT E2 · source reviewed

A TypeScript wrapper for Jev decisions with an explicit unsure branch.

JEV · Decision point

Preserves probabilities and option types and routes uncertainty to a caller-supplied fallback.

Uses types to require uncertainty handling without guaranteeing model correctness.

Production reranker benchmark: TypeSafe Jev vs Qwen3-Reranker-0.6B on BEIR SciFact and NFCorpus — nDCG@10, cost/query and p50/p95 latency. Quality is indistinguishable; Jev is ~2x faster, Qwen ~4x cheaper. From the team at denser.ai

tc39-atlas

hemanth

1174

Domain & Vertical Tools E2 · source reviewed

A TC39 proposal explorer with adoption, complexity and compatibility rubrics, a local demonstration evaluator and a separate TypeSafe System One proxy.

JEV · Decision point

The server-backed route sends proposal state and Choice, Score and Noul questions to TypeSafe. The local typesafeEngine evaluator instead derives simulated values from keywords and rules.

Useful for comparing explicit proposal rubrics and inspecting state. Specification status remains a matter for TC39's primary records, not model scores.
