Excellent migration skill with clear workflow, comprehensive model string mappings across platforms, and thoughtful prompt adjustment guidance. The description accurately conveys what the skill does, and the step-by-step workflow is actionable for an AI agent. Task knowledge is strong with platform-specific mappings and behavioral difference handling. Structure is clean with appropriate use of reference files. Novelty is moderate-to-good: while model string replacement is straightforward, the nuanced prompt adjustments for Opus 4.5 behavioral differences (tool overtriggering, over-engineering, thinking sensitivity) represent valuable domain knowledge that would require research and multiple iterations to discover independently. Minor improvement opportunity: could benefit from examples of before/after code snippets in the main document for common migration scenarios.
