I’ve tried quite a few, from oh-my-openagent’s gargantuan hooks+plugin system to minimal add-i like wozcode, and I’ve been most impressed by that (wozcode) and oh-my-pi. I get that pi is supposed to be roll-your-own but I think OMP’s config is a great starting point; pi removed all the fluff and OMP added just enough orchestration and tooling back in to take things to the next level. Wozcode is great if you like CC because it doesn’t mess with the fundamentals, it just adds things like batching for efficiency—CC’s system prompt alone is absurd.
Caveat: I’m a data scientist/researcher, not a professional SWE, so take my experiences with a grain of salt. I’m just a python monkey most of the time
