1. AI-Assisted Debug Prompt & Tracing: A Revolution in Troubleshooting

We’ve just introduced a powerful solution that pairs Playwright’s built-in tracing with an AI-Assisted Debug Prompt. This feature captures all the underlying browser actions—navigations, screenshots, network calls, console logs—and packages them into:

• A Trace File (.zip) containing step-by-step snapshots of how your test or screenshot process unfolds.
• An AI Debug Prompt (.txt) that extracts error details, stack traces, and relevant code snippets, giving you context to feed into an AI model or share with your development team.
• HAR Files (HTTP Archive) that store all network requests for deeper performance or network-level analysis.

By automatically surfacing relevant debugging information and funneling it into a concise AI prompt, you drastically reduce the time spent guessing “why did the test fail?” or “what's wrong with my site?” Now, you have immediate access to error details and a ready-to-use prompt that can be dropped into any AI assistant or bug tracking system.

2. What It Is

This integrated approach leverages both Playwright’s advanced tracing capabilities and an AI-driven prompt generation. The trace captures low-level details about page load, console output, and navigation steps, while the AI prompt highlights the most critical aspects. Together, they offer developers a quick path from problem to resolution.

3. Why It’s Useful

Rapid Issue Identification

When a screenshot request fails, you’ll receive a comprehensive trace log and an AI prompt that spells out precisely where and why the breakdown occurred.

Deeper Collaboration

The AI Debug Prompt becomes an instant conversation starter with your QA team or an AI-based code assistant.

Faster Feedback Loops

If your screenshot or test pipeline hits an issue, you can instantly see what failed. Quicker fixes, fewer production incidents, and a smoother user experience.

General Website Debugging

This feature is excellent not only for debugging screenshots but also for general website troubleshooting and testing workflows. It's helpful for debugging interactive elements, page loading issues, JavaScript errors, and performance bottlenecks. The combination of Trace Files, AI-generated prompts, and HAR files lets you pinpoint issues precisely, regardless of the screenshot process.

Performance & Network Analysis

The HAR files allow you to analyze network requests, load times, resource bottlenecks, and API failures, making it valuable beyond mere screenshot debugging.

Continuous Integration Testing (CI/CD)

Ideal for automated test scenarios—helping developers instantly see why tests fail, whether due to slow load times, missing selectors, or JavaScript errors.

4. Key Use Cases

Cross-Browser Screenshot Service

Automatically logs failures, producing trace zips and error summaries for instant issue identification and resolution.

Continuous Integration (CI) Testing

Quickly pinpoint issues like timeouts or incorrect selectors, speeding up bug fixes.

Performance & Analytics Debugging

Identify slow load times or unnecessary network calls through combined HAR and trace file analysis.

5. How to Use the Trace File

1. Download the .zip provided by your Node service.
2. Open in Playwright UI:
   • Install Playwright CLI: npm install playwright
   • Run: npx playwright show-trace trace_12345.zip
3. Visualize steps with a time-travel replay of browser actions.

6. How to Use the HAR Files

1. Capture files with capture_har=true for each request.
2. Open HAR files using Chrome/Firefox Developer Tools or third-party apps like Fiddler.
3. Analyze network requests for performance insights.

7. Marketing Recap

With AI-Assisted Debug Prompts and robust tracing, you can quickly and precisely diagnose:

• Why a screenshot or test failed.
• Which network calls or scripts caused slowdowns.
• Where to focus efforts for quicker resolutions.

The result: dramatically faster and more insightful debugging workflows—making your service stand out from the pack.
