Quick Review

This skill provides a structured approach to PostHog SDK upgrades with clear steps, code examples, and breaking change patterns. The description adequately conveys the skill's purpose for CLI invocation. Task knowledge is reasonable with bash commands, TypeScript examples, and a rollback procedure. Structure is clean and organized. However, novelty is limited—most guidance consists of standard npm upgrade commands, changelog review, and code refactoring that a capable CLI agent could perform independently without significant token savings. The skill would benefit from more advanced automation (e.g., scripted breaking change detection, automated codemod transformations, or version compatibility matrix parsing) to justify its existence as a specialized skill rather than general upgrade instructions.
