Agentic Browser

Browser automation for AI agents via inference.sh. Uses Playwright under the hood with a simple @e ref system for element interaction.

Quick Start

Requires inference.sh CLI (infsh). Get installation instructions: npx skills add inference-sh/skills@agent-tools

infsh login

# Open a page and get interactive elements
infsh app run agent-browser --function open --input '{"url": "https://example.com"}' --session new

Core Workflow

Every browser automation follows this pattern:

1. Open - Navigate to URL, get @e refs for elements
2. Interact - Use refs to click, fill, drag, etc.
3. Re-snapshot - After navigation/changes, get fresh refs
4. Close - End session (returns video if recording)

# 1. Start session
RESULT=$(infsh app run agent-browser --function open --session new --input '{
  "url": "https://example.com/login"
}')
SESSION_ID=$(echo $RESULT | jq -r '.session_id')
# Elements: @e1 [input] "Email", @e2 [input] "Password", @e3 [button] "Sign In"

# 2. Fill and submit
infsh app run agent-browser --function interact --session $SESSION_ID --input '{
  "action": "fill", "ref": "@e1", "text": "user@example.com"
}'
infsh app run agent-browser --function interact --session $SESSION_ID --input '{
  "action": "fill", "ref": "@e2", "text": "password123"
}'
infsh app run agent-browser --function interact --session $SESSION_ID --input '{
  "action": "click", "ref": "@e3"
}'

# 3. Re-snapshot after navigation
infsh app run agent-browser --function snapshot --session $SESSION_ID --input '{}'

# 4. Close when done
infsh app run agent-browser --function close --session $SESSION_ID --input '{}'

Functions

| Function | Description | |----------|-------------| | open | Navigate to URL, configure browser (viewport, proxy, video recording) | | snapshot | Re-fetch page state with @e refs after DOM changes | | interact | Perform actions using @e refs (click, fill, drag, upload, etc.) | | screenshot | Take page screenshot (viewport or full page) | | execute | Run JavaScript code on the page | | close | Close session, returns video if recording was enabled |

Interact Actions

| Action | Description | Required Fields | |--------|-------------|-----------------| | click | Click element | ref | | dblclick | Double-click element | ref | | fill | Clear and type text | ref, text | | type | Type text (no clear) | text | | press | Press key (Enter, Tab, etc.) | text | | select | Select dropdown option | ref, text | | hover | Hover over element | ref | | check | Check checkbox | ref | | uncheck | Uncheck checkbox | ref | | drag | Drag and drop | ref, target_ref | | upload | Upload file(s) | ref, file_paths | | scroll | Scroll page | direction (up/down/left/right), scroll_amount | | back | Go back in history | - | | wait | Wait milliseconds | wait_ms | | goto | Navigate to URL | url |

Element Refs

Elements are returned with @e refs:

@e1 [a] "Home" href="/"
@e2 [input type="text"] placeholder="Search"
@e3 [button] "Submit"
@e4 [select] "Choose option"
@e5 [input type="checkbox"] name="agree"

Important: Refs are invalidated after navigation. Always re-snapshot after:

• Clicking links/buttons that navigate
• Form submissions
• Dynamic content loading

Features

Video Recording

Record browser sessions for debugging or documentation:

# Start with recording enabled (optionally show cursor indicator)
SESSION=$(infsh app run agent-browser --function open --session new --input '{
  "url": "https://example.com",
  "record_video": true,
  "show_cursor": true
}' | jq -r '.session_id')

# ... perform actions ...

# Close to get the video file
infsh app run agent-browser --function close --session $SESSION --input '{}'
# Returns: {"success": true, "video": <File>}

Cursor Indicator

Show a visible cursor in screenshots and video (useful for demos):

infsh app run agent-browser --function open --session new --input '{
  "url": "https://example.com",
  "show_cursor": true,
  "record_video": true
}'

The cursor appears as a red dot that follows mouse movements and shows click feedback.

Proxy Support

Route traffic through a proxy server:

infsh app run agent-browser --function open --session new --input '{
  "url": "https://example.com",
  "proxy_url": "http://proxy.example.com:8080",
  "proxy_username": "user",
  "proxy_password": "pass"
}'

File Upload

Upload files to file inputs:

infsh app run agent-browser --function interact --session $SESSION --input '{
  "action": "upload",
  "ref": "@e5",
  "file_paths": ["/path/to/file.pdf"]
}'

Drag and Drop

Drag elements to targets:

infsh app run agent-browser --function interact --session $SESSION --input '{
  "action": "drag",
  "ref": "@e1",
  "target_ref": "@e2"
}'

JavaScript Execution

Run custom JavaScript:

infsh app run agent-browser --function execute --session $SESSION --input '{
  "code": "document.querySelectorAll(\"h2\").length"
}'
# Returns: {"result": "5", "screenshot": <File>}
