--- name: desktop-control-for-macos description: Generic macOS desktop control using AppleScript for app and window semantics plus screenshot, OCR, mouse, and keyboard workflows. --- # 写在前面 特别做了中文兼容，包括文字输入/识别等，中文用户放心使用～ # macos-desktop-control This skill controls the macOS desktop through a small, explicit pipeline with a clear split between semantic app control and visual UI control: ## Features ### 🖥️ App and window control - ✅ Activate an app by name or bundle path - ✅ Check whether an app is running - ✅ Read the current frontmost app - ✅ Read front window title, count windows, and list window titles ### 📸 Screenshot and image operations - ✅ Capture the current screen as a logical-resolution screenshot - ✅ Initialize screenshot-to-click calibration for macOS Retina displays - ✅ Crop a known rectangular region from an image - ✅ Reuse calibration data when a workflow must mix logical and raw screenshots ### 🎯 Visual target location - ✅ Locate targets by AI semantic understanding as the default first choice - ✅ Fall back to OCR when the target is best identified by text - ✅ Fall back to OpenCV image matching when the target has a stable reusable template - ✅ Constrain later actions to coordinates derived from a screenshot ### ⌨️ Mouse and keyboard control - ✅ Move the mouse in logical screen coordinates - ✅ Left click, right click, double click, and drag - ✅ Read current mouse position - ✅ Type text, paste via higher-level workflows, press keys, and send hotkeys - ✅ Hold and release keys explicitly when needed ### 🛡️ Safety and scope - ✅ Use logical coordinates as the default working convention - ✅ Keep app-specific UI semantics out of this skill - ✅ Keep AppleScript usage limited to app and window semantics, not deep UI scripting - ✅ Keep `pyautogui.FAILSAFE = True` so moving to the top-left corner aborts automation 1. Use AppleScript for app and window semantics 2. Initialize coordinate mapping 3. Capture the screen 4. Locate targets by AI semantic understanding first, then fall back to OCR or OpenCV when needed 5. Execute mouse and keyboard actions with Python ## Design boundary This skill intentionally does not include AppleScript UI scripting. Use AppleScript for: - opening or activating apps - reading frontmost app state - reading window titles and counts Use screenshot-guided OCR/OpenCV plus `pyautogui` for: - clicking UI targets - typing into custom-drawn interfaces - interacting with chat rows, images, canvases, or other visually defined targets This boundary keeps the skill predictable. AppleScript is used where semantic macOS state is strong, and `pyautogui` is used where direct UI manipulation is more reliable. ## Why initialization is needed On macOS, screenshot coordinates and click coordinates may use different coordinate systems. - `screencapture` images usually use pixel coordinates. - Mouse automation tools often use macOS screen coordinates, also called point coordinates. - On Retina displays, one point is commonly equal to two pixels. This skill writes the coordinate mapping result to a JSON file, so later steps can reuse it without recalculating. Initialization behavior in the current version: - the skill auto-initializes on first use when the calibration file does not exist - it does not re-run mapping on every invocation - if `/tmp/macos_desktop_control/calibration.json` already exists, the existing calibration is reused Default calibration file: ```bash /tmp/macos_desktop_control/calibration.json ``` ## Directory layout ```text macos-desktop-control/ SKILL.md requirements.txt scripts/ calibration.py init_coordinate_mapping.py capture_screen.py crop_image.py locate_text_ocr.py locate_image_opencv.py mouse.py keyboard.py applescript_app.py applescript_window.py ``` ## Requirements Install Python dependencies: ```bash pip install -r requirements.txt ``` OCR uses Apple Vision through PyObjC, so no separate Tesseract install is required. On macOS, grant the terminal or runtime app these permissions: - Screen Recording - Accessibility ## 1. Initialize coordinate mapping The first version handles Retina screens by comparing screenshot pixel size with the logical screen size used by `pyautogui`. You can still run initialization manually: ```bash python scripts/init_coordinate_mapping.py ``` But in normal use, the skill now performs lazy initialization automatically on first use if the calibration file is missing. Example output: ```json { "screen_width_points": 1512, "screen_height_points": 982, "screenshot_width_pixels": 3024, "screenshot_height_pixels": 1964, "scale_x": 2.0, "scale_y": 2.0, "mode": "retina" } ``` Later scripts read this file automatically. Current lazy-init behavior: - `capture_screen.py` - `mouse.py` - `locate_text_ocr.py` - `locate_image_opencv.py` These scripts first check whether `/tmp/macos_desktop_control/calibration.json` exists. If not, they auto-generate it once and then continue. ## 2. Capture screen Capture the current screen and resize the image into the logical coordinate system used by `pyautogui.position()` and `pyautogui.click()`. This skill's default convention is: - default screenshot is logical - default recognition result coordinates are logical - default mouse action coordinates are logical - default crop operations should use a logical screenshot - only use calibration conversion when a workflow explicitly mixes logical screenshots with raw pixel screenshots ```bash python scripts/capture_screen.py --output /tmp/macos_desktop_control/screen_logical.png ``` Core idea: ```python import pyautogui img = pyautogui.screenshot() screen_w, screen_h = pyautogui.size() # Resize screenshot to the coordinate system used by pyautogui.position() / click(). img = img.resize((screen_w, screen_h)) img.save("screen_logical.png") ``` ## 3. Crop image regions When a higher-level skill already knows a target rectangle, crop it directly instead of re-opening previews or re-running visual search. By default, crop from a logical screenshot so the crop rectangle stays in the same coordinate system as recognition and mouse targeting. Only crop from a raw Retina or pixel screenshot when there is a specific reason to preserve raw pixels, and in that case convert coordinates first using calibration data. ```bash python scripts/crop_image.py \ --image /tmp/macos_desktop_control/screen_logical.png \ --x1 400 --y1 300 --x2 700 --y2 650 \ --output /tmp/macos_desktop_control/crop.png ``` Use this for: - extracting a detected chat image thumbnail - saving a button or dialog region for later analysis - debugging screenshot-to-action pipelines ## 4. Locate targets Use AI semantic understanding as the default first-choice locator. Use OCR or OpenCV only when AI is unsuitable, unavailable, or cannot produce a reliable target. There are three supported strategies. ### Locate by semantic understanding ```bash python scripts/locate_text_ocr.py \ --image /tmp/macos_desktop_control/screen_logical.png \ --text "Confirm" ``` You can also constrain OCR to a specific screen region when the same text may appear in multiple places: ```bash python scripts/locate_text_ocr.py \ --image /tmp/macos_desktop_control/screen_logical.png \ --text "Chats" \ --x1 0 --y1 120 --x2 520 --y2 1107 ``` The script prints the center point of the best matched Apple Vision OCR box. When a region is provided, the search runs only inside that rectangle, but the returned coordinates are still in full-screen logical coordinates. When exact matching methods are unnecessary or brittle, use AI-based image understanding first. This approach is the default when the target has one or more of these properties: its appearance is not fixed, there is no reusable template, the decision depends on surrounding visual context, or the target can only be described semantically. Typical examples: - there are multiple clickable regions on screen and the caller must determine which one is the intended target - the target has no stable text label or icon template, but it can be described in natural language - the workflow requires understanding relationships between visual elements, such as who is speaking or what a region means in context - the target is easier to describe than to match exactly Preferred flow: - capture a screenshot - crop to the smallest reliable region when possible - run AI recognition on that region first - require structured output from AI before acting - if AI cannot produce a reliable target, fall back to OCR or OpenCV - map coordinates, then execute the action AI output contract: - require a compact JSON object - required fields: `found`, `x`, `y`, `confidence`, `reason` - `found` must be boolean - `x` and `y` must be logical screen coordinates when `found=true` - `confidence` should use a small fixed set such as `high`, `medium`, `low` - `reason` should briefly explain why the target was selected or why no reliable target was found Recommended JSON shape: ```json { "found": true, "x": 742, "y": 681, "confidence": "high", "reason": "Located the send button in the lower-right input area" } ``` Safety rule for AI-driven clicks: - if `found=false`, do not click - if `confidence=low`, prefer fallback or verification before clicking This skill is responsible for screenshot capture and coordinate conversion. The caller interprets the recognition result and decides the next action. ### Locate by OCR text ## 5. Mouse actions Use Python and `pyautogui` to control the mouse in logical screen coordinates. ### Single click ```bash python scripts/mouse.py --action click --x 500 --y 300 ``` ### Move only ```bash python scripts/mouse.py --action move --x 500 --y 300 --duration 0.2 ``` ### Double click ```bash python scripts/mouse.py --action double-click --x 500 --y 300 ``` ### Right click ```bash python scripts/mouse.py --action right-click --x 500 --y 300 ``` ### Drag ```bash python scripts/mouse.py --action drag --x 500 --y 300 --to-x 800 --to-y 500 --duration 0.3 ``` ### Read current mouse position ```bash python scripts/mouse.py --action position ``` You can also pipe the result from a locate script: ```bash python scripts/locate_image_opencv.py \ --image /tmp/macos_desktop_control/screen_logical.png \ --template ./target_button.png \ | python scripts/mouse.py --stdin --action click ``` Stdin accepts either `x y` text or JSON like `{"x": 500, "y": 300}`. ## 6. Keyboard actions Use Python and `pyautogui` to paste text or trigger shortcuts. Important practical note: - this skill uses clipboard paste for all text entry by default, including English - this avoids input-method issues with Chinese, English, and mixed-language text - do not use simulated typing for text entry in this skill ### Paste text ```bash python scripts/keyboard.py --action paste --text "I am OpenClaw" ``` ### Paste from stdin ```bash printf 'I am OpenClaw' | python scripts/keyboard.py --action paste --stdin ``` Default input rule for this skill: - use clipboard paste for all text input by default, including English - click the verified input field first, then paste with `command v` - do not use simulated typing for text entry in this skill ### Press one key ```bash python scripts/keyboard.py --action press --key enter ``` ### Press a hotkey ```bash python scripts/keyboard.py --action hotkey --keys command v ``` Recommended paste workflow when text fidelity matters: 1. copy the exact text into the clipboard, preferably via `python scripts/keyboard.py --action paste` 2. click the verified input field 3. let the script send `command v` to paste 4. verify visually before pressing enter if sending would be externally visible ### Hold and release keys ```bash python scripts/keyboard.py --action key-down --key shift python scripts/keyboard.py --action key-up --key shift ``` ## 7. AppleScript app control Use AppleScript when the task is semantic macOS control rather than visual targeting. Good fits: - open or activate an app - check whether an app is running - read the current frontmost app ### Open by app name ```bash python scripts/applescript_app.py --action open --app "WeChat" ``` ### Open by bundle path ```bash python scripts/applescript_app.py --action open --path "/Applications/WeChat.app" ``` ### Activate an app ```bash python scripts/applescript_app.py --action activate --app "WeChat" ``` ### Check whether an app is running ```bash python scripts/applescript_app.py --action is-running --app "WeChat" ``` ### Get the current frontmost app ```bash python scripts/applescript_app.py --action frontmost-app python scripts/applescript_app.py --action frontmost-app --json-pretty ``` ## 8. AppleScript window inspection Use AppleScript window inspection when you need app-level UI state without relying on OCR. Good fits: - read the front window title - count windows for a process - list window titles for a process ### Read the front window title ```bash python scripts/applescript_window.py --action title --app "WeChat" ``` ### Count windows ```bash python scripts/applescript_window.py --action count --app "WeChat" ``` ### List window titles ```bash python scripts/applescript_window.py --action list --app "WeChat" python scripts/applescript_window.py --action title --app "WeChat" --json-pretty ``` ### Locate by OpenCV image matching ```bash python scripts/locate_image_opencv.py \ --image /tmp/macos_desktop_control/screen_logical.png \ --template ./target_button.png \ --threshold 0.8 ``` The script prints the center point of the matched template. Use this as a fallback when AI is not appropriate and the target has a stable reusable visual template. ## 9. When to use AppleScript vs desktop vision Prefer AppleScript for: - opening or activating apps - reading window titles - checking the frontmost app - simple app and process state queries Do not add AppleScript UI scripting here for button clicks or deep accessibility-tree automation. That path is intentionally excluded from this skill. Prefer screenshot + desktop vision + pyautogui for: - buttons or labels that only exist visually - apps with weak or unstable accessibility hierarchies - targets inside custom-drawn UIs such as chat rows, images, or canvas content - direct manipulation such as clicking, dragging, and typing into app surfaces Default visual targeting order in this skill: 1. Try AI semantic understanding first 2. If AI cannot produce a reliable target, fall back to OCR for text-driven targets 3. If OCR is not suitable, fall back to OpenCV template matching for stable visual templates When the same text may appear in multiple places, do not search the full screen by default. Constrain OCR to the intended region first, then click using the returned full-screen logical coordinates. A practical sequence is often: 1. AppleScript activates the app 2. AppleScript reads window or process state 3. AI-based vision tries to find the target first 4. OCR or OpenCV is used only as fallback when needed 5. mouse or keyboard automation performs the action 6. AppleScript or a fresh screenshot verifies the result ## 10. Recommended flow ```bash python scripts/applescript_app.py --action activate --app "WeChat" python scripts/applescript_window.py --action title --app "WeChat" python scripts/init_coordinate_mapping.py python scripts/capture_screen.py # first try AI semantic understanding with a bounded screenshot region when possible # if AI cannot produce a reliable target, fall back to OCR or OpenCV python scripts/locate_text_ocr.py --text "Confirm" python scripts/mouse.py --action click --x 500 --y 300 python scripts/keyboard.py --action press --key enter ``` ## Notes - Version 1 assumes a Retina display and single primary screen. - Treat logical screenshots as the default working surface for this skill. - Treat recognition output coordinates as logical unless a script explicitly says otherwise. - Treat mouse and keyboard targeting as logical by default. - Treat crop rectangles as logical by default, and prefer cropping from a logical screenshot. - If another skill mixes logical screenshots with raw Retina or pixel screenshots, use calibration conversion deliberately. Do not assume logical bounds match raw pixel bounds 1:1. - Keep this skill focused on generic desktop primitives. App-specific UI semantics, business rules, and event pipelines should stay in the higher-level app skill. - Treat AI semantic understanding as the default visual locator, not merely a last-resort add-on. - Require structured AI output with `found`, `x`, `y`, `confidence`, and `reason` before acting on AI-located targets. - Use OCR and OpenCV as fallback tools when AI cannot reliably identify the target. - All click, drag, move, and typing actions use Python / `pyautogui`. - AppleScript support in this skill is limited to app control and window inspection. - For safety, keep `pyautogui.FAILSAFE = True`; moving the mouse to the top-left corner aborts automation.
