Quick Review

This skill provides solid technical guidance for PostHog migration using the strangler fig pattern. The description clearly indicates when to invoke it (migration, upgrade, replatform scenarios). Task knowledge is strong with concrete code examples, phased implementation plans, data migration scripts, and rollback procedures. Structure is logical with clear phases and progressive steps. However, novelty is limited - while migrations require careful planning, most of the content consists of standard adapter patterns, feature flag traffic splitting, and batch data migration that a competent CLI agent could construct with adequate prompting. The skill is useful for consolidating migration best practices but doesn't introduce particularly complex orchestration, multi-system coordination, or domain-specific PostHog intricacies that would be prohibitively expensive for a CLI agent to generate from scratch.
