Bug fixes (Skill 20 - naver_serp_analyzer.py):
- Remove VIEW tab selectors (removed by Naver in 2026)

Improvements (Skill 34 - dashboard/executive report):
- Add Korean category labels for Chart.js charts (기술 SEO, 온페이지, etc.)
- Add Korean trend labels (개선 중 ↑, 안정 →, 하락 중 ↓)
- Add English→Korean issue description translation layer (20 common patterns)

Documentation improvements:
- Add Korean triggers to 4 skill descriptions (19, 25, 28, 31)
- Expand Skill 32 SKILL.md from 40→143 lines (was 6/10, added workflow, output format, limitations)

- Add limitations sections to Skills 27 and 28
- Update README.md, CLAUDE.md, AGENTS.md for skills 33-34

+## Limitations
+
+- Google Knowledge Panel detection via search results is not guaranteed (personalization, location-based)
+- Direct Google scraping may be blocked (403/429); prefer WebSearch tool
+- Wikipedia/Wikidata creation requires meeting notability guidelines
+- PAA questions vary by location and device
+- Entity completeness scoring is heuristic-based
