Browser & OS Action source reviewed

A browser Agent for ego lite that numbers actionable elements for Jev to choose the next step.

JEV · Decision point

Jev selects an operation and target in one request; a separate helper handles free-form text when needed.

Offers observation, suggestions and execution, while uploads and dialogs still require other browser tools.

CLI & Pipelines MIT source reviewed

Software development framework for coding agents enhanced with Jev for dependency vetting, completion gates, and debugging decisions.

JEV · Decision point

Invokes Jev at workflow checkpoints to evaluate change validity, test sufficiency, and package safety before advancing agent state.

Constrains coding agent trajectories using fast discrete judgments, preventing hallucinated dependencies and premature task completion.

Context GC & Filter MIT

Bare, open-source RLM layer for existing coding agents

JEV · Decision point

Jev receives selected source material and explicit questions. It can rank passages, classify records, assess whether evidence supports a claim and judge whether records match for semantic joins. Its returned probabilities let the RLM compare results and decide what to inspect, combine or explore next.

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

keeltrace

226

Decision Tools MIT source reviewed

An asynchronous Jev companion for Hermes Agent covering relevance, completion, recovery and optional admission decisions.

JEV · Decision point

Jev evaluates bounded questions in the background while Hermes retains reasoning and execution responsibilities.

Records decision provenance and supports configuration that avoids blocking ordinary execution.

Security & Guardrails MIT source reviewed

An experimental Hermes command-approval provider for the auxiliary.approval task only.

JEV · Decision point

Jev returns APPROVE, DENY or ESCALATE, with local thresholds and policy determining handling.

Demonstrates an approval integration; the author labels it a proof of concept, not production assurance.

Context GC & Filter MIT

Claude Code / Codex / pi plugin that hands agent steps needing no text output to Jev (TypeSafe's judgment model) — measured p50 ~230 ms and ~$0.02 per 1,000 judgments, with typed escalation back to the LLM

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

A Manifest V3 Chrome port of jev-ultrafast: Jev picks the operation and DOM element in one request per step; a small chat model fills TYPE_TEXT.

JEV · Decision point

Chooses CLICK, TYPE_TEXT, SELECT, SCROLL_DOWN, SCROLL_UP, PRESS_ENTER, WAIT, DONE, or BLOCKED and the matching DOM target in one request; PRESS_ENTER is a separate key control. Separate yes/no checks cover goal completion and a stuck loop.

Runs in the user’s own tabs without screenshots, and keeps the action, target, and typed string inspectable.

Creative Tools MIT source reviewed

Turns a music prompt into editable multitrack MIDI by asking Jev to choose instruments, harmony, and bar patterns.

JEV · Decision point

Selects form, instruments, chords, and rhythm candidates; local code renders the choices as notes.

Preserves editable tracks and decision receipts with playback and MIDI export.
