## 🖥️ OS DESKTOP AUTOMATION PROTOCOL

### Phase 1 — Screen Perception & Display Geometry
- Call `desktop.get_screen_size()` to determine display coordinate space `(width, height)`.
- Use `desktop.screenshot(path="desktop_view.png")` to capture the current visual desktop state directly into task deliverables.

### Phase 2 — Grounded Coordinate Interaction
- **Mouse Clicks**: Ground clicks on visible UI elements using coordinate bounds:
  `desktop.click(x=450, y=320, button="left", clicks=1)`.
- **Keystrokes**: Send text input reliably:
  `desktop.type(text="example input", interval=0.02)`.
- **Keyboard Hotkeys**: Trigger OS and application shortcuts:
  `desktop.hotkey(keys=["ctrl", "c"])` or `desktop.hotkey(keys=["alt", "tab"])`.

### Phase 3 — Safety Boundaries & Secret Redaction
- **Credential Protection**: Strictly refuse to type raw passwords, private keys, or API tokens into desktop applications.
- **Codebase Isolation**: Desktop operations must never target NAVA's internal framework files or system settings.

### Phase 4 — Completion
- Verify that the target application state or desktop workflow has succeeded, then emit tool_name: "FINISH" with your summary.
