I use multiple harnesses and… I don’t get what the fuss is all about? I seriously don’t care what I use for the most part.
I mean a “harness” is basically just something that turns models output to action. Just have model return json with what it wants to execute and execute it is basically it. Your machine _is_ the damn harness.
All the ergonomy and features are doomed to be obsolete as we get better models, so… whatever.
Harness has vast impact on performance, cost and how you extend functionality.
