It used to be quite popular to sh*t on Claude Code (flickering etc). But it's really a good harness now imo.
I have no more flickering, it "just works" with those Claude models.
And now it's getting that new "mods" feature which makes it extremely extensible and customizable.
I still do also use Pi (and also grok build - it's a good harness, too!). All in herdr.
But Claude Code has definitely moved up from my least favorite to one of my preferred ones.
