Interesting project. How does it compare to GSD (opengsd.net)? Just from the command set it seems a lot lighter but also less expressive.

GSD is quite OK but very token hungry (~4x but it buys traceability and has quite a powerful autonomous mode) I use gsd-meta-manager to manage multiple GSD projects in parallel without having to use a skill to query each project individually to see where they're at. Does openspec have something like that too?
