The harness helps a lot even with local models. In fact, I just found this this morning and cherrypicked it: https://github.com/DietrichGebert/ponytail
Recommend doing the same, and for superpowers if you don't have 'em already: https://github.com/obra/superpowers
Opencode Go is the $10/month cloud model subscription from the same group maintaining the OpenCode software. Opencode Zen is a pay-as-you-go version which gives you access to Claude models as well. Keeping pay-as-you-go to subagents only (e.g. telling your agent to launch an opus subagent via your opencode zen key) is actually surprisingly economical - when you're not going turn after turn with hundreds of thousands of tokens of context, claude is pretty reasonably priced.
What I'm doing is spreading out my usage over multiple cheap subscriptions, and augmenting with the occasional pay-as-you-go frontier agent, to get quality in line with what you get out of Claude, at usage that would require the $200/month level, for a lot less money than that.
I’m a little surprised to hear you say PAYG for Opus sub agents is economical. Maybe the superpowers and ponytail really do have a massive impact on things. I’ll send these to three people I know building heavy production apps right now. And integrate them into my own Hermes setup.
Thank you for the recommendations!
Any time, I hope they're helpful! (☞ﾟヮﾟ)☞
I did say it was surprising! 😂 To give you an idea what I mean by "economical", it's never more than a few bucks a day, even on days of heavy use and development with "loop until clean" instructions on QA (for which I use Opus). I accidentally blew through my opencode go quota really early in the first month, so I ended up on PAYG; here's the usage graph:
And here's the numbers breakdown for the highest day (I was evaluating GLM5.1 for general tasks - don't use it for that, it's really token hungry)
That includes a lot of experimentation too while I figured out which models were best for what. I hid Fable because it crushed the rest of the table - really expensive, but worth it for one-shotting very long tasks on the Anthropic subscription is what I found.
Damn those are good numbers!
