Agentic Harness with Jev: 3x Fewer Iterations, 444x Cheaper, Zero Hallucinated Files
Roger_M_Taylor · x · 2026-09-25
A thread + quoted builder's guide explains an agentic harness built with Jev: the lead model (claimed Opus 5.5) holds the whole codebase in context while eight executor agents make typed decisions — files, commands, and a 0–1 confidence score — instead of paragraphs. The model can only pick from allowed options, every decision is verified before touching code, and a memory layer preserves state across agents.
Results claimed: 8 agents close a task in 3 iterations instead of 10, 193x faster and 444x cheaper, with zero hallucinated files; output includes code, tests, docs, confidence and next steps. The quoted article is a step-by-step guide with full code, architecture and diagrams.
