decision-first

Agent skill that pushes a coding agent to try Jev before it writes another regex or prompt, then writes down what happened.

jev-system-one

Python terminal app that puts Jev on both sides of an OpenAI answer. A LangGraph pipeline asks Jev for response mode, clarification and depth, has OpenAI draft, then has Jev score whether the draft answers the question and whether it carries unsupported claims before approving or sending it back.

haseeb-heaven/jev-system-onePython

trade-jev

Backtest harness that asks Jev for a BUY, SELL or HOLD call every 15 seconds on NQ L10 order-book data and trades one contract against hold, random and imbalance baselines. Runs cost money; replays of stored answers under new settings are free, and a local web app replays any mix of runs live.

mcts-agent

Python agent that runs Discriminative MCTS with Jev judging and Gemini 3.8 Flash proposing. Choice supplies action priors and branching width, Score evaluates states on a 1-10 rubric, and Noul checks execution and ends the loop at 0.85 confidence, with a local web UI for following runs.

skill-router

Claude Code CLI that ranks every skill installed on your machine against a session goal using Jev, then tells the agent which one to load. Three possible answers: load this skill, nothing you have installed fits, or no skill is needed, and nothing else runs for the rest of the session.

Jev Agents & MCP#community#jevbest#catalog-import

todo-jev

Python CLI that classifies a request into one of three tiers — local rule, structured decision or skill, or foundation model — using TypeSafe Jev, 20 bundled skill profiles with exclusion conditions, and local environment checks.
