cloudflare-browser-rendering

mrgoonie

Guide for implementing Cloudflare Browser Rendering - a headless browser automation API for screenshots, PDFs, web scraping, and testing. Use when automating browsers, taking screenshots, generating PDFs, scraping dynamic content, extracting structured data, or testing web applications. Supports REST API, Workers Bindings (Puppeteer/Playwright), MCP servers, and AI-powered automation. (project)

Systematic Debugging

mrgoonie

Four-phase debugging framework that ensures root cause investigation before attempting fixes. Never jump to solutions.

Root Cause Tracing

mrgoonie

Systematically trace bugs backward through call stack to find original trigger

Verification Before Completion

mrgoonie

Run verification commands and confirm output before claiming success

Defense-in-Depth Validation

mrgoonie

Validate at every layer data passes through to make bugs impossible
