mdmanager packages runtime-specific discovery, reusable Sections and Profiles, an instruction-focused TUI, and bundled CLI docs into something you can install and use.
You could build that with Ansible too, but the interface, domain rules, documentation, and maintenance are part of what you’d be building. Packaging all the nuances of 4 runtimes in was a lot of work.
If your existing setup already gives you everything you need, great. You don’t need this. That doesn’t make a dedicated tool redundant for everyone else.
“Ansible can do that” is a reasonable implementation suggestion. Taken it too far then “Python can do that” becomes an objection to everything posted on HN.
And no LLM is required for discovery, rendering, or deployment. Using an agent to edit the configuration is a workflow choice.
