Has any harness matched the effectiveness of Claude Code yet? I haven't experimented much recently, but every time I have in the past, I wasn't able to get any other tool to approach how effective I am in CC.
I'd love to use a different harness-- ideally an OSS one-- and hook it up to whichever LLM provides the best bang for the buck rather than being tied to Claude.
OpenCode has been great in my experience. I still get the best results using it with Anthropic's models, but some of the open weights ones are catching up (GLM 5 works reasonably well for me).
