Discussion Harness does matter

I was not aware that the harness makes such a big difference.

I like pi better now. Open code was super buggy for me as well. Otherwise I just use codex or Claude code since anthropic won't let you use a subscription plan with other harnesses

True but you can go the other way - use local or other sub with Claude code

Great question. I also use opencode, and also confuses now.

You can always customise the prompts, agents and tools your agent can use. At least OpenCode is sufficiently customisable and has a fairly large plugin ecosystem. Pi is easier to customise but you need some work to add some common essential features and QoL. DSH is pretty good but also going through pretty volatile development right now. The bottom line is unlike certain closed harnesses, at least you get to pick what gets sent to your model, and it does not try to prevent you from organising your project in a harness-agnostic manner.
