E2E Test Scenario Quality Review

Systematic checklist for reviewing E2E spec files AND Page Object Model (POM) files. Covers Playwright and Cypress with full grep + LLM analysis. General principles (name-assertion alignment, missing Then, YAGNI) apply to any framework, but automated grep patterns are Playwright/Cypress-specific.

Phase 0: Framework Detection

Classify the requested mode:

• Full mode (default): review the requested suite, directory, or repository.
• Diff mode: review a supplied PR, patch, range, or changed-file list using the supplied patch or read-only git metadata; never guess an unavailable base.
