A method for platform-agnostic software installation involves obtaining a knowledge package, where the knowledge package includes guidelines for obtaining and installing software deliverables. The method further involves obtaining a profile, where the profile includes platform-agnostic data indicating a desired system state. The method further involves distributing the knowledge package and the profile to a first managed host and a second managed host, where the first managed host has a first operating system platform, and where the second managed host has a second operating system platform. The method further involves filtering the profile based on the knowledge package to obtain a first platform-specific profile for the first managed host and a second platform-specific profile for the second managed host, updating the first managed host to the desired system state using the first platform-specific profile, and updating the second managed host to the desired system state using the second platform-specific profile.
