Desktop Agent Ops

---

name: desktop-agent-ops

description: Execute cross-platform desktop tasks through a packaged desktop automation skill that guides the main agent to observe the screen, focus apps and windows, call helper scripts for screenshots and input actions, verify each step, clean up task context, and only escalate to multi-agent collaboration when tasks become clearly multi-window or multi-app. Use when the user wants desktop GUI control, native app operation, window focus, screenshots, click and type flows, or cross-platform desktop workflows on macOS, Windows, or Linux.

# Desktop Agent Ops

Use this skill as a **main-agent operating manual** for desktop GUI tasks.

---

MANDATORY: Auto-setup gate (FIRST ACTION, every time)

python3 <SKILL_DIR>/scripts/first_run_setup.py --check

If `"ready": false`, run setup (installs EVERYTHING automatically):

python3 <SKILL_DIR>/scripts/first_run_setup.py

**Auto-installs on first run:**

1. Platform detection (macOS / Windows / Linux)

2. `cliclick` + `tesseract` (macOS via brew; Linux guide printed)

3. OCR language packs auto-detected from system locale (中文→chi_sim, 日本語→jpn, etc.)

4. Python venv + pillow, pyautogui, pytesseract, opencv-python, numpy (via uv or pip)

5. OS permissions (Screen Recording, Accessibility, Automation) with auto-open System Settings

6. Smoke test (screenshot + mouse move verification)

After setup, set `$PY` for ALL subsequent calls:

PY=<output.env.DESKTOP_AGENT_OPS_PYTHON>

**Do NOT proceed if setup is not ready.**

Core Execution Loop

Every desktop task follows this loop. No exceptions.

 1. auto-setup gate           ← run once per session
 2. init task context          ← create isolated temp directory
 3. FOCUS the target app       ← bring app to front, confirm frontmost
 4. GET window bounds          ← know exact position and size
 5. CAPTURE that window        ← screenshot ONLY the target window
 6. ANALYZE the capture        ← read screenshot or run OCR
 7. LOCATE target via OCR      ← find text/button within window bounds
 8. VERIFY before acting       ← move cursor, screenshot with cursor, confirm
 9. EXECUTE one action         ← click, type, scroll, press key
10. CAPTURE again              ← screenshot to see result
11. VERIFY the result          ← did the UI change as expected?
12. → if more steps, go to 5
13. CLEANUP                    ← remove task temp directory

**Key principles:**

Window-Scoped Targeting (THE CORRECT WAY)

**NEVER do OCR or clicking on a full-screen screenshot.** Always scope to the target app window.

The 6-Step Pipeline

┌─────────────────────────────────────────────────────────┐
│ Step 1: FOCUS the target app                            │
│   $PY desktop_ops.py focus-app --name "AppName"         │
│   → brings app to front                                 │
├─────────────────────────────────────────────────────────┤
│ Step 2: GET window bounds                               │
│   $PY desktop_ops.py front-window-bounds --app "AppName"│
│   → {x, y, width, height} in logical coordinates        │
├─────────────────────────────────────────────────────────┤
│ Step 3: CAPTURE only that window                        │
│   $PY desktop_ops.py capture-region --x X --y Y         │
│     --width W --height H --output /tmp/window.png       │
├─────────────────────────────────────────────────────────┤
│ Step 4: OCR within the window                           │
│   $PY ocr_text.py --app "AppName" --python $PY          │
│   → abs_box coordinates are INSIDE the window           │
├─────────────────────────────────────────────────────────┤
│ Step 5: VERIFY before clicking                          │
│   $PY desktop_ops.py move --x TX --y TY                 │
│   $PY desktop_ops.py screenshot --with-cursor            │
│   → confirm cursor is on the right element              │
├─────────────────────────────────────────────────────────┤
│ Step 6: CLICK only if verified                          │
│   $PY desktop_ops.py click --x TX --y TY                │
│   $PY desktop_ops.py screenshot → verify result          │
└─────────────────────────────────────────────────────────┘

Shortcut (RECOMMENDED for most targeting):

$PY scripts/target_resolver.py --app "AppName" --text "按钮文字" --python $PY

This single command: focuses app → gets bounds → OCR within window → returns `best_candidate` with `{x, y, within_window}`.

Why window-scoped matters:

| Approach | Risk |

|----------|------|

| ❌ Full-screen OCR | "搜索" in WeChat AND Chrome → clicks wrong app |

| ✅ Window-scoped | "搜索" ONLY in WeChat window → correct click |

---

Failure Recovery (CRITICAL)

When something fails, follow these rules:

OCR finds nothing

1. Re-focus the app: `focus-app --name "AppName"`

2. Re-get bounds: `front-window-bounds --app "AppName"` (window may have moved/resized)

3. Take a fresh screenshot and read it visually

4. Try a different region label (e.g. `content_area` instead of `bottom_input`)

5. Try lowering OCR confidence: `--min-conf 30`

Click doesn't work

1. Screenshot with cursor to check cursor position

2. The window may have moved — re-get bounds

3. Try clicking a few pixels offset from the OCR center

4. Check if a dialog/popup is blocking the target

App state changed (login screen, dialog, etc.)

1. ALWAYS re-get window bounds after any major UI change

2. ALWAYS re-run OCR after navigation or state change

3. Never reuse old coordinates — they may be stale

General retry rule

Generalization: How to Apply This to ANY App

The pipeline works for any desktop application. Here is how to reason about new apps:

Step-by-step for ANY new app:

1. **Identify the app name** exactly as it appears in the system (e.g. "Google Chrome", "微信", "System Settings")

2. **Focus and get bounds** — this tells you the window's exact position

3. **Screenshot the window** — look at what's on screen

4. **Identify the target** — what text, button, or area do you need to interact with?

5. **Use OCR to find it** — `target_resolver.py --app "AppName" --text "target text"`

6. **Verify and click**

Common patterns across apps:

| Task | How to do it |

|------|-------------|

| Click a button | OCR find text → verify → click |

| Type in a field | OCR find field label → click field → `type --text` |

| Search for something | OCR find search box → click → type query → press return |

| Scroll a list | Get window bounds → scroll at window center with `--x --y` |

| Switch between apps | `focus-app --name "OtherApp"` → re-get bounds |

| Handle a dialog | Screenshot → OCR for dialog buttons → click appropriate one |

| Navigate menus | Click menu item → wait → screenshot → OCR new menu → click |

| Select from dropdown | Click dropdown → wait → OCR options → click selection |

| Read screen content | OCR the window → extract all text boxes |

| Verify an action | Screenshot before and after → compare or OCR for expected text |

App-specific adaptations:

| App type | Special considerations |

|----------|----------------------|

| Chat apps (WeChat, Slack, etc.) | Verify conversation title before typing; use `insert-newline` for multi-line; verify send mechanism |

| Browsers (Chrome, Safari, etc.) | Address bar at top; content area varies; may need to handle tabs |

| System Settings | Deep navigation; panels change; re-get bounds after each navigation |

| File managers (Finder, Explorer) | Sidebar + content area; double-click to open; path bar for navigation |

| Editors (VS Code, TextEdit, etc.) | Tab bar + editor area; use hotkeys for save/undo; type in editor area |

---

Text Input and Send Rules

Typing text

$PY scripts/desktop_ops.py type --text "your message"

Multi-line messages

$PY scripts/desktop_ops.py type --text "first line"
$PY scripts/desktop_ops.py insert-newline
$PY scripts/desktop_ops.py type --text "second line"

Sending a message

1. **Preferred**: Look for a visible send button (e.g., `发送`) via OCR, then click it

2. **Alternative**: Use `press --key return` ONLY when the app is verified to use Enter-to-send

3. **Never guess** which send method to use — verify first

Backend priority (macOS)

| Operation | Primary | Fallback |

|-----------|---------|----------|

| `type` | Clipboard paste | cliclick (ASCII only) |

| `press` | AppleScript `key code` | cliclick `kp:` |

| `hotkey` | cliclick `kd:/t:/ku:` | pyautogui |

| `click` | cliclick | pyautogui |

> **Important**: cliclick `kp:return` is NOT recognized by WeChat — always use AppleScript for key press.

> **Important**: cliclick `t:` silently drops CJK characters — always use clipboard paste for text input.

---

DPI / HiDPI / Retina (All Platforms)

**Handled automatically.** No manual DPI work needed.

| Platform | Common scales | Detection method |

|----------|---------------|-----------------|

| macOS Retina | 2.0x | screenshot pixels ÷ logical screen bounds |

| Windows HiDPI | 1.25x, 1.5x, 2.0x | screenshot pixels ÷ pyautogui.size() |

| Linux X11 | 1.0x, 1.5x, 2.0x | screenshot pixels ÷ pyautogui.size() |

OCR output: `box` = logical (use for mouse), `pixel_box` = raw pixels, `dpi_scale` = factor.

9. $PY target_resolver.py --app "WeChat" --text "" --region-label bottom_input --python $PY
   OR: click at the bottom center of the window
10. $PY desktop_ops.py type --text "Hello!"
11. # Send: prefer visible send button; if not available, use press --key return
12. $PY target_resolver.py --app "WeChat" --text "发送" --python $PY
    IF found: $PY desktop_ops.py click --x <x> --y <y>
    ELSE: $PY desktop_ops.py press --key return

Scope

Use this skill for: chat apps, browsers, file managers, editors, office apps, system settings, any closed desktop software with no usable API.

Hard Rules

1. **Always run auto-setup gate first**

2. **Always use EXACT parameter names from CLI reference — never guess**

3. **Always scope OCR to the target app window — NEVER full-screen OCR**

4. **Always: focus-app → front-window-bounds → OCR within window → verify → act**

5. **Always pass `--python $PY` to ocr_text.py and target_resolver.py**

6. **Always verify coordinates are within window bounds before clicking**

7. **Always re-get window bounds after any UI state change (login, dialog, navigation)**

8. **Use `insert-newline` for line breaks; never use `\n` in `type --text`**

9. **For send actions: prefer visible send button; use `press --key return` only when verified**

10. **One action at a time; verify after each**

11. **Maximum 3 retries per action; each retry must recapture fresh state**

12. **Cleanup is mandatory at task end**

13. **If verification fails, recapture and rebuild — do not retry blindly**
