How I Built a CLI Tool That Generates and Manages Its Own Infrastructure

No digging through config files, no cross-referencing documentation, no wondering whether what's on disk matches what's actually running. Just the card. That's the idea behind SwiftDeploy. You write one file — manifest.yaml — and a CLI tool called swiftdeploy reads it an
