zsh integration with claude code cli

I'm interested in implementing this feature and would love to contribute
Native shell integration would make Claude Code feel like a first-class terminal tool

I'd appreciate some guidance on:
Preferred approach for zsh completion scripts
Whether there have been any previous attempts or discussions around shell integration?
Testing strategies for shell integration features

Would love to learn from any existing work or attempts made in this direction, and happy to collaborate on making this feature a reality.
