Context GC & Filter MIT E2 · source reviewed

An X/Twitter filtering extension using local rules by default, with optional Jev checks for unmatched replies.

JEV · Decision point

When experimental AI is enabled, Jev evaluates replies missed by rules and local thresholds decide whether to hide them.

Browser & OS Action MIT E2 · source reviewed

A browser library, CLI and MCP server where the caller supplies goals and text while Jev selects actions.

Context GC & Filter MIT E2 · source reviewed

A context filter for Claude Code that hides irrelevant tool-output blocks and keeps the original text available for recall.

JEV · Decision point

Jev scores whether Read, Bash and Grep output blocks are needed; local thresholds keep relevant or uncertain blocks.

Reduces visible output while retaining a way to retrieve hidden text.

CLI & Pipelines MIT E1 · source linked

Filters text, structured records, functions, and diff hunks against plain-English descriptions using Jev Noul judgments.

JEV · Decision point

Jev judges whether each input unit matches the user description; local code applies the probability threshold and returns matching source material.

Evaluation & Observability MIT E2 · 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.
