Ds160 Autofill

# DS-160 Auto-fill Skill

This skill automates the filling of US nonimmigrant visa DS-160 forms by combining:
- CDP (Chrome DevTools Protocol) for fast element location
- CSV data source for user information
- LLM assistance for complex cases (captcha, missing elements)
- Session persistence for resume capability
- Chinese to English translation for user input

## Quick Start

### Starting a New Application

1. **Provide CSV data**: User must provide a CSV file with their personal information (use `ds160-user-info.csv` as template)

2. **Open DS-160 website**: Use `browser` tool to open `https://ceac.state.gov/genniv/` with profile `openclaw`

3. **Initialize session**: Load and execute `scripts/ds160-filler.js` to parse mappings and CSV

4. **Start filling**: Begin with the home page, handle captcha with LLM, then proceed page by page

### Resuming an Application

1. **Load existing session**: Check `ds160/ds160-session.json` for saved Application ID

2. **Open application**: Use the saved Application ID to resume on DS-160 website

3. **Continue filling**: Load CSV from saved location and continue from last page

## Core Workflow

### Step 1: Prepare Data

**Always check if session exists first:**
```javascript
// Read ds160/ds160-session.json
// If exists → Resume mode
// If not → New application mode
```

**New application mode:**
- Ask user for CSV file path or content
- Save CSV to `ds160/ds160-user-info.csv` using `write` tool
- Initialize session data in `ds160/ds160-session.json`:
  ```json
  {
    "applicationId": null,
    "securityQuestion": null,
    "securityAnswer": null,
    "currentPageIndex": 0,
    "completedPages": [],
    "startDate": "2026-02-06T21:00:00Z"
  }
  ```

**Resume mode:**
- Load CSV from `ds160/ds160-user-info.csv`
- Load session from `ds160/ds160-session.json`
- Report current progress to user

### Step 2: Initialize Browser

```javascript
// Open browser with openclaw profile
browser_start: { profile: "openclaw", targetUrl: "https...
