- Lead with one calm summary line and one clear action.
- Keep the visual language restrained, dark, and readable at a glance.
Build shape
- Prefer a menu-bar popover or compact status-item panel.
- Show the primary state first, then the useful detail lines.
- Shows battery state and energy mode without the noise of a diagnostics dump.
- Pairs well with lightweight trend cues and significant energy usage.
- Stays calm enough to live in the menu bar all day.
Guardrails
- Do not invent unsupported metrics or background services.
- Keep the app simple enough to feel native on macOS.
- Use one primary action and a small set of supporting actions.
Prototype
- SwiftUI starter files live in
prototype/. - The prototype should stay menu-bar first and easy to transplant into a real macOS target.
When extending

- If the skill grows, keep the menu-bar path short and the detail panel readable.
