Quick Review

Excellent legacy modernization skill with clear invocation triggers, comprehensive workflow, and well-organized reference structure. The description is specific enough for CLI agents to invoke appropriately (strangler fig, monolith decomposition, framework upgrades). Strong task knowledge is evident through the 5-step workflow and detailed reference guide covering testing, migration strategies, and refactoring patterns. Structure is clean with a concise overview and modular references for detailed guidance. The skill addresses a genuinely complex domain where ad-hoc CLI attempts would be risky and token-intensive, providing real value through systematic safety-first approaches. Minor improvement opportunity: could include example scenarios or decision trees for choosing between migration strategies.
