Evaluation & Observability MIT source reviewed

Keeps an execution ledger for Claude Code and Codex CLI to check for passing validation after edits.

JEV · Decision point

Jev can identify completion claims and semantic-rule issues; stop gates depend on ledger facts and local rules.

Separates execution evidence from model opinion rather than letting Jev alone certify completion.

ufec

299

Security & Guardrails MIT source reviewed

An Android notification and SMS filter that applies local OTP rules before asking Jev whether a message is advertising noise.

JEV · Decision point

Classifies text that passes local gates; local mapping decides whether to allow or suppress it.

Makes OTP handling and fail-open behavior explicit in code.

High-Frequency & Simulation source reviewed

A browser Doom experiment comparing Jev-controlled players from the same initial state.

JEV · Decision point

Jev reads structured health, ammunition and targets and selects tactical controls executed by a local controller.

Exposes model decisions alongside explicitly labeled offline and fallback policies.

Evaluation & Observability MIT source reviewed

A word-level generation experiment that asks Jev to select words or verify locally drafted continuations.

JEV · Decision point

Choice selects the next word; Noul evaluates candidate chunks and stopping conditions.

Exposes the limitations of using a decision model as a text generator.

Routing & Cost Optimization MIT

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.
