This is one of the many reasons I don't think the model companies are going to win the application space in coding.

There's literally zero context lost for me in switching between model providers as a cursor user at work. For personal stuff I'll use an open source harness for the same reason.

I don't see any value in chat history. I delete all conversations at least weekly, it feels like baggage.

I think this is more about which model you steer your coding harness to. You can also self-host a UI in front of multiple models, then you own the chat history.

for me there is zero value there.

I have a CLAUDE.md symlinked to AGENTS.md

ln -s CLAUDE.md AGENTS.md

There's your one line change.

And as others have said, it's a one-line fix. "Skills" etc. are another `ln -s`
