Comprehensive web testing: unit, integration, E2E, load, security, visual regression, accessibility.

Quick Start

npx vitest run                    # Unit tests
npx playwright test               # E2E tests
npx playwright test --ui          # E2E with UI
k6 run load-test.js               # Load tests

  • E2E: Critical flows (login, checkout, payment)
  • Load: Pre-release performance validation
  • Security: Pre-deploy vulnerability scanning
  • Visual: UI regression detection

pdf-to-markdown

aliceisjustplaying

Convert entire PDF documents to clean, structured Markdown for full context loading. Use this skill when the user wants to extract ALL text from a PDF into context (not grep/search), when discussing or analyzing PDF content in full, when the user mentions "load the whole PDF", "bring the PDF into context", "read the entire PDF", or when partial extraction/grepping would miss important context. This is the preferred method for PDF text extraction over page-by-page or grep approaches.
