The tool uses YAML manifests to declare desired system state and supports cross-platform package management (Homebrew, apt, winget, pacman/yay, BSD pkg). Key features include running individual manifests, fetching remote manifests via URL (useful for cloud-init), and a DAG-based dependency system. The session covers the codebase architecture including the atom/action pattern for idempotent operations, and live-codes a new OS context provider to expose system information (OS type, architecture) for use in manifest predicates and Jinja-style templating. ## Full article daily.dev links to this article rather than hosting it.
