A lot of the system prompt, skills and tools center around my specific needs (I manage separate IMAP and Gmail inboxes, use Granola, and have iCloud calendars). And there are some hard assumptions baked in (I want to have a morning & afternoon check-in). It probably wouldn't be useful as-is, but maybe as inspiration?
They're neck and neck for me, in terms of PRDs, coding, and web searching. CC built the bulk of my current project, I did a lot of analysis of it with Antigravity (the interface is esp good for reviewing/commenting on long .md output files) and then, after building a simple roadmap of v2 features, OpenCode + Kimi was the most aggressive about running in a fairly autonomous manner and finishing the items on said roadmap. OC was also pretty hardcore about misinterpreting a limit I expressed earlier in one context as a limitation in another context -- which was fine, I'd rather say "no, really, you can go do that, I'm giving you permission and here's what I meant before" than find out it was too brazen.
It's a lot like managing two experienced mid- to sr- engineers each of whom have slightly different personalities and intro/extro verted personalities. CC has more personality but OC wants to race. They can both code, but for disparate tasks you might pick the personality and posture of one person over the other.
I find myself picking daily tasks based on which of the tools I'm in the mood to sit with. But across a few days I sit with all three.
I wouldn't say it was oneshotted, but it did produce a working MVP in one Plan execution. Meaning, I went back & forth a few times about requirements, it built a plan, and then CC spent just under 15 minutes writing the code. Once I got the credentials plugged in, the core integrations (Slack, gmail, IMAP, iCloud calendar) and agent loop did work. I can share the initial message if you're curious.
I'd love to see even a filtered version of it. I've been doing very similar things with an "everything" database. That's been my own personal northstar.
BTW, OpenCode has free Kimi (I haven't hit a quota yet) right now and it's done pretty great things for me in the last 24 hours.
