Configures the Oh My Claude Code heads-up display in your statusline. You get three presets: minimal shows just the essentials, focused (default) adds context percentage and agent counts, and full expands running agents into a multi-line tree view with durations and what each is doing. Colors shift from green to yellow to red as context fills up or Ralph iteration counts climb. The setup is a bit involved because it has to wire a Node wrapper script into settings.json and handle both Unix and Windows path quirks, but once it's running you get live visibility into Ralph loops, PRD stories, active skills, background tasks, and context pressure without opening another pane.
