Thanks so much! This is absolutely intended for James Bond-inspired play, and was directly drawn from my experiences of watching the classic Bond movies with my mum.
I don't have much advice for playing in Foundry, as I've little experience with it myself outside of playing in a few Pathfinder 2e games using it, but as far as I know the basic FitD/progress clock tools should serve you well - Spies is hyper-compressed, but is at heart not far off from base Blades, so anything you'd normally do in Foundry re: running Blades or similar should be good.
