Agent Touch Layer

# ATL — Agent Touch Layer

> The automation layer between AI agents and iOS

ATL provides HTTP-based automation for iOS Simulator — both browser (mobile Safari) and native apps. Think Playwright, but for mobile.

🔀 Two Servers: Browser & Native

ATL uses two separate servers for browser and native app automation:

| Server | Port | Use Case | Key Commands | |--------|------|----------|--------------| | Browser | `9222` | Web automation in mobile Safari | `goto`, `markElements`, `clickMark`, `evaluate` | | Native | `9223` | iOS app automation (Settings, Contacts, any app) | `openApp`, `snapshot`, `tapRef`, `find` |

``` ┌─────────────────────────────────────────────────────────────┐ │ BROWSER SERVER (9222) │ NATIVE SERVER (9223) │ │ (mobile Safari/WebView) │ (iOS apps via XCTest) │ │ │ │ │ markElements + clickMark │ snapshot + tapRef │ │ CSS selectors │ accessibility tree │ │ DOM evaluation │ element references │ │ tap, swipe, screenshot │ tap, swipe, screenshot │ └─────────────────────────────────────────────────────────────┘ ```

Why two ports? Native app automation requires XCTest APIs (XCUIApplication, XCUIElement) which are only available in UI Test bundles. The native server runs as a UI Test that exposes an HTTP API.

Starting the Servers

```bash # Browser server (starts automatically with AtlBrowser app) xcrun simctl launch booted com.atl.browser curl http://localhost:9222/ping # → {"status":"ok"}

# Native server (run as UI Test) cd ~/Atl/core/AtlBrowser xcodebuild test -workspace AtlBrowser.xcworkspace \ -scheme AtlBrowser \ -destination 'id=<SIMULATOR_UDID>' \ -only-testing:AtlBrowserUITests/NativeServer/testNativeServer & # Wait for it to start, then: curl http://localhost:9223/ping # → {"status":"ok","mode":"native"} ```

Quick Port Reference

| Task | Port | Example | |------|------|---------| | Browse websites | 9222 | `curl localhost:9222/command -d '{"method":"goto",...}'` | | Open native app | 9223 | `curl localhost:9223/command -d '{"method":"openApp",...}'` | | Screenshot (browser) | 9222 | `curl localhost:9222/command -d '{"method":"screenshot"}'` | | Screenshot (native) | 9223 | `curl localhost:9223/command -d '{"method":"screenshot"}'` |

📱 Native App Automation (Port 9223)

Native automation uses port 9223 and automates any iOS app using the accessibility tree — no DOM, no JavaScript, just direct element interaction.

Opening & Closing Apps

```bash # Open an app by bundle ID curl -s -X POST http://localhost:9223/command \ -d '{"method":"openApp","params":{"bundleId":"com.apple.Preferences"}}' # → {"success":true,"result":{"bundleId":"com.apple.Preferences","mode":"native","state":"running"}}

# Check current app state curl -s -X POST http://localhost:9223/command \ -d '{"method":"appState"}' # → {"success":true,"result":{"mode":"native","bundleId":"com.apple.Preferences","state":"running"}}

# Close current app curl -s -X POST http://localhost:9223/command \ -d '{"method":"closeApp"}' # → {"success":true,"result":{"closed":true}} ```

Common Bundle IDs

| App | Bundle ID | |-----|-----------| | Settings | `com.apple.Preferences` | | Contacts | `com.apple.MobileAddressBook` | | Calculator | `com.apple.calculator` | | Calendar | `com.apple.mobilecal` | | Photos | `com.apple.mobileslideshow` | | Notes | `com.apple.mobilenotes` | | Reminders | `com.apple.reminders` | | Clock | `com.apple.mobiletimer` | | Maps | `com.apple.Maps` | | Safari | `com.apple.mobilesafari` |

The `snapshot` Command

`snapshot` returns the accessibility tree — all visible elements with their properties and tap-able references.

```bash curl -s -X POST http://localhost:9223/command \ -d '{"method":"snapshot","params":{"interactiveOnly":true}}' | jq '.result' ```

Example output: ```json { "count": 12, "elements": [ { "ref": "e0", "type": "cell", "label": "Wi-Fi", "value": "MyNetwork", "identifier": "", "x": 0, "y": 142, "width": 393, "height": 44, "isHittable": true, "isEnabled": true }, { "ref": "e1", "type": "cell", "label": "Bluetooth", "value": "On", "identifier": "", "x": 0, "y": 186, "width": 393, "height": 44, "isHittable": true, "isEnabled": true }, { "ref": "e2", "type": "button", "label": "Back", "value": null, "identifier": "Back", "x": 0, "y": 44, "width": 80, "height": 44, "isHittable": true, "isEnabled": true } ] } ```

• Parameters:
• `interactiveOnly` (bool, default: `false`) — Only return hittable elements
• `maxDepth` (int, optional) — Limit tree traversal depth

The `tapRef` Command

Tap an element by its reference from the last `snapshot`:

```bash # Take snapshot first curl -s -X POST http://localhost:9223/command \ -d '{"method":"snapshot","params":{"interactiveOnly":true}}'

# Tap element e0 (Wi-Fi cell from example above) curl -s -X POST http://localhost:9223/command \ -d '{"method":"tapRef","params":{"ref":"e0"}}' # → {"success":true} ```

The `find` Command

Find and interact with elements by text — no need to parse snapshot manually:

```bash # Find and tap "Wi-Fi" curl -s -X POST http://localhost:9223/command \ -d '{"method":"find","params":{"text":"Wi-Fi","action":"tap"}}' # → {"success":true,"result":{"found":true,"ref":"e0"}}

# Check if an element exists curl -s -X POST http://localhost:9223/command \ -d '{"method":"find","params":{"text":"Bluetooth","action":"exists"}}' # → {"success":true,"result":{"found":true,"ref":"e1"}}

# Find and fill a text field curl -s -X POST http://localhost:9223/command \ -d '{"method":"find","params":{"text":"First name","action":"fill","value":"John"}}'

# Get element info without interacting curl -s -X POST http://localhost:9223/command \ -d '{"method":"find","params":{"text":"Cancel","action":"get"}}' # → {"success":true,"result":{"found":true,"ref":"e5","element":{...}}} ```

• Parameters:
• `text` (string) — Text to search for (matches label, value, or identifier)
• `action` (string) — One of: `tap`, `fill`, `exists`, `get`
• `value` (string, optional) — Text to fill (required for `action:"fill"`)
• `by` (string, optional) — Narrow search: `label`, `value`, `identifier`, `type`, or `any` (default)

🔄 Native App Workflow Example

Here's a complete flow: open Settings, navigate to Wi-Fi, take a screenshot:

```bash # 1. Open Settings app curl -s -X POST http://localhost:9223/command \ -d '{"method":"openApp","params":{"bundleId":"com.apple.Preferences"}}'

# 2. Wait for app to launch sleep 1

# 3. Take snapshot to see available elements curl -s -X POST http://localhost:9223/command \ -d '{"method":"snapshot","params":{"interactiveOnly":true}}' | jq '.result.elements[:5]'

# 4. Find and tap Wi-Fi curl -s -X POST http://localhost:9223/command \ -d '{"method":"find","params":{"text":"Wi-Fi","action":"tap"}}'

# 5. Wait for navigation sleep 0.5

# 6. Take screenshot of Wi-Fi settings curl -s -X POST http://localhost:9223/command \ -d '{"method":"screenshot"}' | jq -r '.result.data' | base64 -d > /tmp/wifi-settings.png

# 7. Navigate back (swipe right from left edge) curl -s -X POST http://localhost:9223/command \ -d '{"method":"swipe","params":{"direction":"right"}}'

# 8. Close the app curl -s -X POST http://localhost:9223/command \ -d '{"method":"closeApp"}' ```

💡 Core Insight: Vision-Free Automation

ATL's killer feature is spatial understanding without vision models:

``` ┌─────────────────────────────────────────────────────────────┐ │ markElements + captureForVision = COMPLETE PAGE KNOWLEDGE │ └─────────────────────────────────────────────────────────────┘

1. markElements → Numbers every interactive element [1] [2] [3]
2. captureForVision → PDF with text layer + element coordinates
3. tap x=234 y=567 → Pixel-perfect touch at exact position
4. ```

• Why this matters:
• No vision API calls — zero token cost for "seeing" the page
• Faster — no round-trip to GPT-4V/Claude Vision
• Deterministic — same page = same coordinates, every time
• Reliable — pixel-perfect coordinates vs. vision interpretation

The Vision-Free Workflow

```bash # 1. Mark elements (adds numbered labels + stores coordinates) curl -s -X POST http://localhost:9222/command \ -d '{"id":"1","method":"markElements","params":{}}'

# 2. Capture PDF with text layer (machine-readable, has coordinates) curl -s -X POST http://localhost:9222/command \ -d '{"id":"2","method":"captureForVision","params":{"savePath":"/tmp","name":"page"}}' \ | jq -r '.result.path' # → /tmp/page.pdf (text-selectable, contains element positions)

# 3. Get specific element's position by mark label curl -s -X POST http://localhost:9222/command \ -d '{"id":"3","method":"getMarkInfo","params":{"label":5}}' | jq '.result' # → {"label":5, "tag":"button", "text":"Add to Cart", "x":187, "y":432, "width":120, "height":44}

# 4. Tap at exact coordinates curl -s -X POST http://localhost:9222/command \ -d '{"id":"4","method":"tap","params":{"x":187,"y":432}}' ```

The marks tell you WHERE everything is. The PDF tells you WHAT everything says. Together = full page understanding.

🎯 The Escalation Ladder

When automation gets stuck, escalate through these levels:

``` ┌─────────────────────────────────────────────────────────────┐ │ Level 1: COORDINATES (fast, cheap, no API calls) │ │ markElements → getMarkInfo → tap x,y │ │ │ │ ↓ If stuck after 2-3 tries... │ │ │ │ Level 2: VISION FALLBACK (screenshot to understand state) │ │ screenshot → analyze UI → identify blockers (modals, etc) │ │ │ │ ↓ If still stuck... │ │ │ │ Level 3: JS INJECTION (direct DOM manipulation) │ │ evaluate → dispatchEvent → force interactions │ └─────────────────────────────────────────────────────────────┘ ```

When to Escalate

| Symptom | Likely Cause | Action | |---------|--------------|--------| | Tap succeeds but nothing changes | Modal/overlay opened | Screenshot → find new button | | Cart count doesn't update | Site needs login or has bot detection | Try JS click with events | | Element not found after scroll | Marks are page-relative, not viewport | Use `getBoundingClientRect` via evaluate | | Same error 3+ times | UI state changed unexpectedly | Screenshot to see actual state |

Real-World Pattern: E-commerce Checkout

```bash # 1. Search and find product atl_goto "https://store.com/search?q=headphones" atl_mark

# 2. First, dismiss any modals/banners (ALWAYS DO THIS) # Look for: close, dismiss, continue, accept, no thanks, got it CLOSE=$(atl_find "close") [ -n "$CLOSE" ] && atl_click $CLOSE

# 3. Find and click Add to Cart ATC=$(atl_find "Add to cart") atl_click $ATC

# 4. Wait, then CHECK if it worked sleep 2 atl_screenshot /tmp/after-click.png

# 5. If cart didn't update, LOOK at the screenshot # Maybe a "Choose options" modal opened - find the NEW Add to Cart button # This is the vision fallback - you need to SEE what happened ```

Key Insight: Modals Change Everything

1. When you click "Add to cart" on sites like Target, Amazon, etc., they often:
2. Open a "Choose options" modal (size, color, quantity)
3. Show an upsell (protection plans, accessories)
4. Display a confirmation with "View cart" or "Continue shopping"

Your original tap WORKED — you just can't see the result without a screenshot.

🚀 Quick Start (30 seconds)

```bash # 1. Setup (boots sim, installs ATL) ~/.openclaw/skills/atl-browser/scripts/setup.sh

# 2. Navigate somewhere curl -s -X POST http://localhost:9222/command \ -d '{"id":"1","method":"goto","params":{"url":"https://example.com"}}'

# 3. Mark elements (shows [1], [2], [3] labels) curl -s -X POST http://localhost:9222/command \ -d '{"id":"2","method":"markElements","params":{}}'

Setup (First Time)

1. Start Simulator ```bash # Boot iPhone 17 simulator (or another device) xcrun simctl boot "iPhone 17"

# Open Simulator app open -a Simulator ```

2. Build & Install AtlBrowser ```bash cd ~/Atl/core/AtlBrowser

# Build for simulator (RECOMMENDED: target by UDID) # Why: name-based destinations can cause Xcode to pick an older iOS runtime (15/16) # and fail if AtlBrowser has an iOS 17+ deployment target. # # 1) Find a suitable simulator UDID (iOS 17+): # xcrun simctl list devices available # # 2) Build targeting that UDID: xcodebuild -workspace AtlBrowser.xcworkspace \ -scheme AtlBrowser \ -destination 'id=<SIM_UDID>' \ -derivedDataPath /tmp/atl-dd \ build

# Install to a specific simulator (preferred) xcrun simctl install <SIM_UDID> \ /tmp/atl-dd/Build/Products/Debug-iphonesimulator/AtlBrowser.app

# Launch the app xcrun simctl launch <SIM_UDID> com.atl.browser ```

3. Verify Server ```bash curl -s http://localhost:9222/ping # Should return: {"status":"ok"} ```

# 6. Repeat as needed ```

Troubleshooting

Navigation not working (goto returns success but page doesn't change) Known issue: `goto` command may return success without navigating. Use JS workaround: ```bash # Instead of goto, use evaluate to navigate curl -s -X POST http://localhost:9222/command -H "Content-Type: application/json" \ -d '{"id":"1","method":"evaluate","params":{"script":"location.href = \"https://example.com\"; true"}}'

# Wait for page load sleep 3 curl -s -X POST http://localhost:9222/command -H "Content-Type: application/json" \ -d '{"id":"2","method":"waitForReady","params":{"timeout":10}}' ```

Server not responding ```bash # Check if app is running xcrun simctl listapps booted | grep atl

# Restart the app xcrun simctl terminate booted com.atl.browser xcrun simctl launch booted com.atl.browser

# Check logs xcrun simctl spawn booted log show --predicate 'process == "AtlBrowser"' --last 1m ```

Need to rebuild (iOS version changes) ```bash cd ~/Atl/core/AtlBrowser xcodebuild -workspace AtlBrowser.xcworkspace -scheme AtlBrowser -sdk iphonesimulator build xcrun simctl install booted ~/Library/Developer/Xcode/DerivedData/AtlBrowser-*/Build/Products/Debug-iphonesimulator/AtlBrowser.app xcrun simctl launch booted com.atl.browser ```

Port 9222 in use The ATL server runs inside the simulator app. If port 9222 is blocked, check for other processes: ```bash lsof -i :9222 ```

Best Practices

1. Clean UI Before Acting Real users dismiss popups. You should too. ```bash # Before any workflow, check for and dismiss: # - Cookie consent banners # - Newsletter popups # - Health/privacy consent modals # - "Download our app" prompts atl_mark for KEYWORD in "close" "dismiss" "no thanks" "accept" "got it" "continue"; do LABEL=$(atl_find "$KEYWORD") [ -n "$LABEL" ] && atl_click $LABEL && sleep 1 done ```

2. Verify State After Actions Don't assume — confirm. ```bash atl_click $ADD_TO_CART sleep 2 # Check if cart updated CART=$(atl_find "cart [1-9]") if [ -z "$CART" ]; then # Didn't work - take screenshot to see why atl_screenshot /tmp/debug.png echo "Action may have opened a modal - check screenshot" fi ```

3. Use Viewport Coordinates for Taps Marks give page-relative coordinates. For tap to work, the element must be visible. ```bash # Option A: Scroll element into view first curl -s -X POST http://localhost:9222/command -H "Content-Type: application/json" \ -d '{"id":"1","method":"evaluate","params":{"script":"document.querySelector(\"#my-button\").scrollIntoView()"}}'

# Option B: Get viewport-relative coords via JS curl -s -X POST http://localhost:9222/command -H "Content-Type: application/json" \ -d '{"id":"2","method":"evaluate","params":{"script":"var r = document.querySelector(\"#my-button\").getBoundingClientRect(); JSON.stringify({x: r.x + r.width/2, y: r.y + r.height/2})"}}' ```

4. Screenshot is Your Debugging Superpower When in doubt, look. ```bash atl_screenshot /tmp/current-state.png # Then analyze with vision or just open the file ```

Notes

• ATL runs inside the iOS Simulator, sharing the host's network
• Port 9222 is the default (matches Chrome DevTools Protocol convention)
• The mark system shows red numbered labels on interactive elements
• Screenshots are PNG base64-encoded; use `base64 -d` to decode
• iOS 26+ compatible (fixed NWListener binding issue)

Requirements

• macOS with Xcode installed
• iOS Simulator (comes with Xcode)
• That's it!

Examples

• See `examples/` folder:
• `test-browse.sh` - Quick bash test workflow
