E2E Failed Test Debugger

Diagnose Playwright test failures from report files. Classifies root causes and provides concrete fixes.

Prerequisites: Run Tests First

Do NOT run playwright test directly and read its stdout — output may be truncated by token-optimizing proxies (e.g. rtk). Instead:

npx playwright test --reporter=json 2>/dev/null > playwright-report/results.json

Then parse the report file in Phase 1.

Phase 1: Extract Failures

# Find report if path not specified
find . -name "results.json" -path "*/playwright-report/*" | head -5
