**The reverse-skill repository provides a unified browser automation stack that routes security testing requests to either Playwright for web automation or OpenReverse for Windows desktop UI automation, orchestrated through a three-dimensional routing matrix in [`skills/config/routing.json`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/config/routing.json).**

The **reverse-skill** repository by zhaoxuya520 implements a platform-neutral "skill router" for security workflows. This guide covers implementing browser automation for security testing using its dual-stack approach—combining Playwright's headless browser capabilities with OpenReverse's desktop UI automation—governed by an intelligent routing system that matches user intent to the correct tool chain.

## How the Routing Matrix Directs Browser Automation Requests

At the heart of reverse-skill lies the **routing matrix** defined in [`skills/config/routing.json`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/config/routing.json) and documented in [`skills/routing.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/routing.md). This three-dimensional structure evaluates:

- **Target type** (web application, desktop binary, API endpoint)
- **User intent** (open webpage, fill form, capture traffic, manipulate UI)
- **Toolchain availability** (Playwright, Node.js, OpenReverse, PowerShell)

When a request matches patterns like "open webpage / browser automation / fill form" or "desktop automation / Windows automation" (lines 102-104 of [`routing.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/routing.md)), the **master routing** system in [`skills/MASTER-ROUTING.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/MASTER-ROUTING.md) resolves the path to [`browser-automation/SKILL.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/browser-automation/SKILL.md). The `master-route.ps1` script performs this resolution programmatically:

```powershell

# Primary routing – resolves the skill path

powershell -NoProfile -ExecutionPolicy Bypass -File skills/scripts/master-route.ps1 `
    -Hint "open webpage / browser automation / fill form"

# Expected output: → browser-automation/

```

The [`RULES.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/RULES.md) file imposes gating constraints on this routing—enforcing security policies such as "no ACT before auth & network profile"—ensuring browser automation executes within proper operational boundaries.

## Setting Up the Browser Automation Environment

Before executing automation scripts, initialize a sandboxed case workspace that records scope and maintains evidence isolation.

### Initialize a Case Workspace

The `case-init.ps1` script creates the directory structure under `work/<case>/` and generates a [`scope.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/scope.md) file:

```powershell

# Create a new case workspace and generate scope.md

powershell -File skills/scripts/case-init.ps1 -Hint "browser-automation-demo"

```

### Verify Tool Availability

The [`tool-index.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/tool-index.md) file maintains an auto-generated inventory of detected tools. Confirm Playwright and OpenReverse presence before execution. The browser-automation skill validates these dependencies through entries in [`skills/tool-index.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/tool-index.md).

## Implementing Web Automation with Playwright

Playwright handles **headless or full-browser automation** for modern web stacks—navigation, form interaction, screenshot capture, and single-page application (SPA) testing.

### Installation and Basic Execution

Node-based scripts reside in `browser-automation/scripts/`. First-time setup requires Playwright installation:

```bash

# Install Playwright (first-time only)

npm i -D playwright

# Run a simple navigation + screenshot script

node browser-automation/scripts/playwright-demo.js \
    --url "https://example.com" \
    --output "./work/browser-automation-demo/screenshot.png"

```

### Core Playwright Script Structure

The [`playwright-demo.js`](https://github.com/zhaoxuya520/reverse-skill/blob/main/playwright-demo.js) file in `browser-automation/scripts/` implements the standard pattern:

```javascript
const { chromium } = require('playwright');
const argv = require('minimist')(process.argv.slice(2));

(async () => {
  const browser = await chromium.launch({ headless: true });
  const page = await browser.newPage();
  await page.goto(argv.url);
  await page.screenshot({ path: argv.output });
  await browser.close();
})();

```

This pattern supports security testing workflows including:
- **Authentication flow capture** – programmatic login with credential injection
- **DOM state extraction** – harvesting form structures and hidden fields
- **Network interception** – capturing XHR/fetch traffic for API analysis
- **Visual regression** – screenshot comparison for detecting UI changes

## Implementing Desktop Automation with OpenReverse

OpenReverse extends automation to **Windows desktop applications** through UI Automation (UIA/CUA) interfaces, with optional MITM proxying for network traffic observation.

### Executing OpenReverse Automation

PowerShell wrappers in `browser-automation/scripts/` drive the OpenReverse CLI:

```powershell

# Launch a Windows Calculator automation via OpenReverse

powershell -File browser-automation/scripts/openreverse-demo.ps1 `
    -App "calc.exe" `
    -Actions @(
        @{ type="click"; selector="Button1" },
        @{ type="click"; selector="Button2" },
        @{ type="click"; selector="ButtonEquals" }
    )

```

### OpenReverse Security Testing Capabilities

The `openreverse-demo.ps1` script wraps OpenReverse functionality for:

- **UI element manipulation** – programmatic clicking, text entry, menu navigation
- **Runtime state inspection** – extracting control properties and window hierarchies
- **Network traffic capture** – MITM proxy integration for observing encrypted desktop app communications
- **Binary behavior analysis** – correlating UI actions with network requests

This proves essential for testing thick-client applications, legacy enterprise software, or desktop components of hybrid web-desktop systems.

## Evidence Collection and Reporting

After automation execution, the `ops/` contracts and `docs-generator/` module produce verifiable evidence:

```powershell

# After automation, produce a Markdown report

powershell -File skills/docs-generator/generate-report.ps1 `
    -Case "browser-automation-demo" `
    -Template "templates/browser-report.md"

```

The generator outputs:
- **Timeline reconstruction** – chronological automation steps with timestamps
- **Evidence graph** – visual relationships between network captures, screenshots, and UI states
- **Structured report** – Markdown/HTML documentation suitable for audit trails

## CI Verification and Quality Assurance

All browser automation paths undergo continuous integration testing across Windows and Ubuntu environments:

| Script | Purpose | Location |
|--------|---------|----------|
| `test-routing.ps1` | 163-case regression suite | `skills/scripts/test-routing.ps1` |
| `verify-routing-coherence.ps1` | Structural and supply-chain validation | `skills/scripts/verify-routing-coherence.ps1` |
| `smoke.ps1` | Quick health check for critical paths | Repository root |

These scripts ensure routing resolution, script execution, and evidence generation remain functional across platform updates.

## Frequently Asked Questions

### How does reverse-skill choose between Playwright and OpenReverse?

The routing matrix in [`skills/config/routing.json`](https://github.com/zhaoxuya520/reverse-skill/blob/main/skills/config/routing.json) evaluates three dimensions: target type (web vs. desktop), user intent (open webpage vs. manipulate UI), and toolchain availability. Web targets route to Playwright; Windows desktop targets route to OpenReverse. The `master-route.ps1` script performs this resolution in milliseconds based on the user's hint string.

### What security policies restrict browser automation execution?

The [`RULES.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/RULES.md) file enforces gating logic such as "no ACT before auth & network profile"—meaning certain aggressive automation actions require authentication and network scope definition first. The routing system validates these preconditions before permitting script execution, preventing unauthorized or out-of-scope automation.

### Can I extend browser-automation with custom scripts?

Yes. Each skill module follows a self-contained directory structure with [`SKILL.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/SKILL.md) documentation. Add Node.js scripts to `browser-automation/scripts/` for Playwright extensions, or PowerShell scripts for OpenReverse workflows. The [`tool-index.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/tool-index.md) auto-detects new tools, and [`routing.md`](https://github.com/zhaoxuya520/reverse-skill/blob/main/routing.md) accepts new matrix entries to expose custom scripts through the master router.

### How does evidence collection work for compliance requirements?

The `ops/` contracts generate a structured timeline and evidence graph automatically. The `docs-generator/generate-report.ps1` script produces Markdown/HTML reports with embedded screenshots, network captures, and UI state logs. All artifacts reside in the case-specific `work/<case>/` directory, providing an immutable audit trail for security assessments.
