hx

Coding-agent instructions, skills, prompts and configuration quickly drift across laptops, remote servers and different harnesses. Copying files by hand makes it difficult to see which version is authoritative or what will change on the next machine.

hx is a Rust CLI that scans supported coding harnesses, builds an explicit synchronisation plan and applies selected changes across local and remote machines. Team Mode adds approved profiles, policy distribution and metadata-only audit without copying private file contents into a central service.

Background synchronisation would be convenient, but too opaque for files that govern agent behaviour. hx previews every change, uses hash preflights before writing and records enough state to roll back. Synchronisation stays local-first and observable.

A developer product that combines a focused CLI, safe distributed change application and a credible path from open-source utility to team governance.
