I need to manage skill files across 2 Macs and 1 VPS, and also across fast inferencing APIs vs. very slow local models.

The first dimension is easy: I simply keep copies of debugged skill files in iCloud and copy them where I need them.

The second dimension is where I spend my time: I use short skill files for fast inference APIs and tiny skill files when I am running slow local models, and I simply spend a lot of time writing and tuning tiny skills files.

Of course, with increasingly better models, skill files become less relevant, but not totally irrelevant.
