Fly IO
ericrisco/rsc-harnessUse when deploying or operating an app on Fly.io — writing fly.toml, placing Machines in regions near users, attaching Volumes, managing secrets, or picking a scaling lever (autostop/autostart, scale count, fly-replay). NOT choosing which host to deploy on (that is `deployment`), NOT a git-push PaaS with no regions model (that is `railway`).
At a glance
This skill is for DevOps & Infrastructure and helps you configure fly.toml for app deployment, place machines in optimal regions, and attach and manage volumes.
