Hermes and Opik close a reviewed loop so agents improve from traces without updating weights

Developers can now wire a two-path loop in which an agent saves working procedures from successful runs and turns production failures into diagnosed, approved, and retested harness changes—without updating model weights. The workflow, described in a technical walkthrough of Hermes Agent and Comet’s open-source Opik platform, treats skills, prompts, tool descriptions, configuration, and evaluation cases as the artifacts that actually change system behavior.
