# Agentic Browser

Browser automation for AI agents via [inference.sh](https://inference.sh). Uses Playwright under the hood with a simple `@e` ref system for element interaction.

## Quick Start

```bash
# Install CLI
curl -fsSL https://cli.inference.sh | sh && infsh login

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

> **Install note:** The [install script](https://cli.inference.sh) only detects your OS/architecture, downloads the matching binary from `dist.inference.sh`, and verifies its SHA-256 checksum. No elevated permissions or background processes. [Manual install & verification](https://dist.inference.sh/cli/checksums.txt) available.

## 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)

```bash
# 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": "[email protected]"
}'
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:

```bash
# 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):

```bash
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:

```bash
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:

```bash
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:

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

### JavaScript Execution

Run custom JavaScript:

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

infsh app run agent-browser --function screenshot --session $SESSION --input '{
  "full_page": true
}'

# Close and get video
RESULT=$(infsh app run agent-browser --function close --session $SESSION --input '{}')
echo $RESULT | jq '.video'
```

## Sessions

Browser state persists within a session. Always:

1. Start with `--session new` on first call
2. Use returned `session_id` for subsequent calls
3. Close session when done
