Rust coding agent harness for running many parallel agents with low RAM

Agent Decisions0.78Runner-up: Classification & Routing
Automated README summary

Automatically summarized from the README on 22 Oct 2026; not a run by jevbooks. Run instructions and author-reported outcomes still need verification.

What it is

jcode is a high-performance coding agent harness written in Rust, aimed at developers running heavy multi-agent workflows. It emphasizes low memory per session, fast startup, swarm collaboration between agents in the same repo, and self-modification of its own source.

How it uses Jev

The README only states that jcode uses native TypeSafe Jev typed decision transport for memory pruning, browser navigation, and voice interaction routing. It does not describe the state passed in, the specific typed questions asked, or how returned probabilities are consumed in code.

Model judgments from README excerpts

Project signals use repository metadata, an existing summary and the first 700 README characters, not the full project. “Not found” means not detected in that material; it does not establish absence. These are the original judgments with recorded models and dates, not source audits or run results.

Evidence

These signals use repository metadata, an existing summary and at most 700 cleaned README characters. ≥ 0.60 means reported in that excerpt; ≤ 0.40 means not found there. The middle band is inconclusive. None is a source-code audit or a test result. The runnable-tool question excludes research experiments; the recommendation question asks for a learning shortlist, not a quality verdict.
