 ### Common Errors and Solutions
@@ -359,12 +623,24 @@ After suggesting fixes, re-run the relevant tests to verify resolution:
 These tools cannot test:
 - Semantic meaning of content
 - Cognitive load
- Time-based media (captions, audio descriptions)
+- Caption accuracy (speech-to-text validation) - Only presence is checked
 - Complex user interactions
- Context-dependent issues
+- Context-dependent issues (some sensory characteristics need human judgment)
+- Video frame-by-frame flash analysis (simplified estimation used)
+- Complex ARIA widget validation (basic validation only)

 Always recommend manual testing with assistive technologies for comprehensive audits.

+**NEW Tool Limitations:**
+- **Gradient Contrast:** Complex gradients (radial, conic) may not be fully analyzed
+- **Media Validation:** Cannot verify caption accuracy, only presence
+- **Hover/Focus:** May miss custom implementations using non-standard patterns
+- **Text-in-Images:** OCR struggles with stylized fonts, handwriting, low contrast
+- **Cross-Page:** Requires 2+ pages, may flag intentional variations
+- **Sensory Characteristics:** Context-dependent, may have false positives
+- **Animation/Flash:** Simplified flash rate estimation, no actual frame analysis
+- **Enhanced A11y:** Simplified reference validation, doesn't check all ARIA states
