Thanks for filing this, @saikoumudi! This is a helpful catch — users shouldn't have to discover missing prerequisites (git, node) through cryptic error messages.

I've labeled this as bug + skills since it's an installation-time failure tied to missing setup instructions, and removed the untriaged label. Since this is already assigned to a coding agent, it will look into updating the README/setup docs to include the winget commands for installing git and node as prerequisites.
