Quick Review

Excellent migration skill with comprehensive coverage of presentation platform migrations to Gamma. The description clearly indicates when to use this skill (migration scenarios from PowerPoint, Google Slides, Canva, etc.). Task knowledge is robust with detailed TypeScript implementations for inventory, migration engines, platform-specific handlers, validation, and rollback procedures. The structure is logical, progressing through 5 clear steps with a helpful checklist and platform comparison table. Code is production-ready with error handling, retry logic, and concurrency controls. Novelty score reflects that while migration tasks are valuable, the pattern (inventory → migrate → validate → rollback) is relatively standard for data migration workflows. The skill meaningfully reduces token costs by providing reusable migration infrastructure that would otherwise require extensive custom development, especially for the platform-specific handlers and metadata extraction.
