Quick Review

This skill provides a structured approach to upgrading the Instantly SDK with clear steps for version checking, changelog review, branch creation, and breaking change handling. The description adequately covers the skill's purpose and trigger phrases. Task knowledge is strong with concrete examples of import/configuration changes, deprecation handling, and rollback procedures. Structure is logical and easy to follow. However, novelty is limited - a CLI agent with web access could accomplish most of these tasks by reading documentation and running standard npm/git commands. The skill primarily codifies best practices rather than providing unique automation or complex logic that would significantly reduce token usage or enable capabilities beyond a standard agent's reach. The compatibility matrix and code examples are helpful but not particularly sophisticated.
