All this mucking about with harnesses and context is really just Markdown engineering.

i definitely considered something like this for the local-first harness i made ... i just don't think most people have the RAM to be able to run two good models yet. maybe i'm wrong though. but i also think a single "agent" can compartmentalize itself into subdivisions better than we imagine (i.e., much much better than any single human can). i ended up creating a broker, though, so at least the tool calls don't eat up as much context. and the auto-reset thing is definitely legit.
