customerio-upgrade-migration

Quick Review

This is a high-quality, comprehensive skill for Customer.io SDK upgrades and migrations. The description clearly explains when to invoke it with specific trigger phrases. The task knowledge is excellent, providing detailed step-by-step instructions with working bash scripts, TypeScript examples, test suites, and a staged rollout strategy. The structure is logical and well-organized with clear sections from assessment through verification. The skill demonstrates good novelty by addressing a complex multi-step process (SDK migration with breaking changes, rollback planning, staged rollout) that would require significant token expenditure and coordination for a CLI agent to accomplish from scratch. Minor improvements could include more explicit cross-platform handling and additional API version migration scenarios, but overall this is a robust, practical skill that meaningfully reduces the complexity of a non-trivial migration task.
