agreed. OpenCode is a strong base, and with a couple modifications it can become a very effective harness. my sideproject mouse.dev I’ve been combining parts from OpenCode, Claude Code, and Hermes to build a cloud agent architecture that works well from mobile.

I personally didn't find it to be competitve with Claude Code as a harness. Can I ask how you modified it to perform better?

		I haven’t run formal evals but i improved the experience for my own needs and it feels noticeably better with these modifications. -Claude-style subagents -an MCP layer for higher-level tools -Cursor-style control plane modes like Ask, Plan, Debug, and Build. The MCP layer lets the harness use things like GitHub file/code read, PR creation, web search/fetch, structured user questions, plan-mode switching, user skills, and subagents. So the improvement is mostly from better ui/ux orchestration and tool access. There's some things from hermes that are interesting as well. Most of my focus has been on applying this stack to sandboxed cloud agents so you can properly code and work from mobile devices. I can't definitively say that the stack is better or worse than Claude code, more just tuned for my use case I guess.
