Category: devtools

Tags: agent-harness, local-first, go

Score: 7.0/10 (Innovation: 7, Technical: 7, Documentation: 8, Utility: 6)

Jeju is an experimental local-first agent harness that defines agent behavior through manifests, enabling developers to create bounded, inspectable, and evaluable agents for local workflows. Its combination of config-defined behavior, strict execution boundaries, and evaluation-guided improvement offers a novel approach to packaging specialist AI agents as portable bundles.

Target audience: backend devs, devops, data engineers
