This listing includes an overview and project link; a reviewed Jev decision point is not yet available.

Open the project link to review its source material and implementation.

Reviews Agent Skills and MCP configurations and source code with local static checks and TypeSafe Jev before installation or execution, reporting file and line evidence, risk categories, model probabilities, and coverage gaps.

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.

Evaluation & Observability MIT source reviewed

A toolkit for evaluating Jev probabilities on labeled data, selecting confidence thresholds and checking model drift.

JEV · Decision point

Runs fixed questions and measures accuracy, calibration, coverage and escalation rates.

Connects threshold selection and model-change checks to reports and CI.

grep for what code does, not what it's called. Semantic code search powered by TypeSafe Jev.

JEV · Decision point

Measured (2026-09-19, jev-1.13.0): a 896-chunk TypeScript `src/` tree in 1.8 s for $0.010 (240k input tokens); repeat query 0 s from cache.

Routing & Cost Optimization MIT

Automatic model router for Pi coding assistant: integrates Jev via Vercel AI Gateway to dispatch tasks efficiently.

JEV · Decision point

Quickly estimates task complexity from code context and user query, routing between SLMs and frontier models.

Brings out-of-the-box intelligent cost-saving routing directly into the Pi terminal workflow.

CLI & Pipelines MIT source reviewed

A CLI and stdio MCP server for typed Jev judgments over text or JSON.

JEV · Decision point

Submits noul, choice and score questions and emits JSON or a primary value.

Accepts files and stdin for use in shell scripts and MCP clients.

Decision Tools MIT

A commit-msg hook that scores the message against the staged diff with one Jev request of five Nouls and warns by default. Default blocking is a local regex belt on high-precision added-line hits; the secret_shaped Noul blocks only with --strict.

JEV · Decision point

Five Noul questions in one request: checkable message, hunk match, debug leftovers, unmentioned work, and credential-shaped added lines. Default blocking is the regex belt; secret_shaped participates only under --strict.

Turns commit-message review into thresholded probabilities instead of prose; API failures still allow the commit.

Adds Jev diagnostic-value, priority and routing signals to OpenTelemetry logs before deeper analysis.

JEV · Decision point

Scores log records and judges whether they merit further model analysis.

Can annotate records while preserving the existing archive path.

CLI & Pipelines MIT

Ranks text along a plain-English criterion using pairwise Jev Noul comparisons and a locally fitted Bradley-Terry scale.

JEV · Decision point

Jev judges whether text A ranks higher than text B on the supplied criterion; local code schedules comparisons and fits a Bradley-Terry scale with standard errors.

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

Security & Guardrails MIT

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.

Data & Search Apache-2.0 source reviewed

A Python reranker that packs a query and up to 30 candidates into one Jev state, with one Noul relevance question per document.

JEV · Decision point

One Noul relevance question per document; long lists are chunked and scored, then filtered by threshold or sorted.

Uses a probability as a threshold or sort key instead of a generative reranker.

Routing & Cost Optimization MIT source reviewed

An opt-in Hermes Agent plugin that asks Jev to suggest one relevant skill before a model call.

JEV · Decision point

Compares the request with the skill roster; inserts a suggestion only when suitable and abstains on failure.

Adds a targeted skill hint that the Agent can still ignore.

Keeps choices within an application-owned action table while requiring separate outcome verification.
