Overview

Surveys the model or the space rather than one pattern.

481 rows are filed under this pattern, 459 of them with code. Rows are listed as the catalogue orders them: official first, then rows with code, then by stars.

Rows marked “not Jev itself” or “shadow mode” stay listed, but they are not examples of deciding with Jev.

42. agent-router

    Plugin · ★119 · typescript

    CLI that picks the coding agent, model and effort for a task and starts it in Herdr: fixed rules filter by quota and a 40% reserve on shared accounts, Jev ranks the rest and picks the effort, and an unsure pick on a consequential task goes back to you. Cursor, Claude Code, Codex or OpenCode.written by a model

43. stanley-code

    Project · ★119 · typescript

    Code-change checker CLI: a Jev choice routes each request to a workflow or cannot_tell; each workflow is code asking Jev small questions about bounded evidence, such as whether a hunk belongs to the task or a test got weaker.

    Project · ★114 · python

    Side-by-side T-Rex runner where Laya, a local model on Apple Silicon via MLX, and Jev over TypeSafe's API each choose the next move from those a physics planner labels; safety checks can override a stale or unsafe pick unless --unassisted is set.
