alt Hacker NewsHarness engineering is a moat. There’s user loyalty and reliance on the chassis that Claude is on, for example, just like there’s more market share by MacOS+WindowsOS over Linux Open Source.

The industry on tooling have been very much moving in direction of "plug the AI of your choosing" for a while now, and given how much Anthropic fights the 3rd party tools they are definitely afraid to be left in the dust.

It's hard to change OS. It's not hard to jump from one AI tool to another
I thought so too.
But 1) people use other models with that same harness. 2) I moved on from Claude Code and all the features I cared for up and running in less than a couple days. Without even looking for available plugins or extensions.

I mean, if that’s the case, then Anthropic themselves are currently actively filling in that moat with nice, solid, walkable dirt. Claude Code may have been a moat 6 months ago but these days you’ll want to replace the “m” with a “bl”.
I regularly switch between codex and Claude in the same sessions. I’d throw in other models if I could.
Data governance and enterprise sales is a moat. The harnesses aren’t.
