 "what": "JevHarness is a Python project where an LLM writes a task-specific harness, meaning code and Jev judgment questions that turn task observations into actions, with optional reward-based reflection to improve it.",
 "why": "",
 "language": "Python",
 "requirements": [
  "Claude Code or Codex installed",
  "Git, and Node.js for the local archive viewer",
  "Access to Jev model calls, since plugin installation does not configure model keys",
  "A Python environment if you plan to build and run a harness yourself"
 ],
 "audience_note": "Developers and AI agent builders who want an LLM to design a fixed decision harness that later runs on fast Jev calls.",
