retellai-upgrade-migration

Quick Review

This skill provides a structured workflow for upgrading Retell AI SDK with breaking change detection and migration guidance. The description clearly indicates when to use it (SDK upgrades, deprecations, version changes). Task knowledge is solid with concrete bash commands, code examples showing import/config changes across versions, and a compatibility matrix. Structure is clear with logical steps from version checking to rollback. However, novelty is limited—a CLI agent could perform these steps (checking versions, reading changelogs, running npm install, running tests) without much difficulty. The skill essentially documents a standard upgrade workflow rather than providing automation or complex breaking-change detection logic that would significantly reduce token usage or enable capabilities beyond basic CLI commands. The deprecation warning handler is a nice touch but still straightforward. Overall, it's a well-documented upgrade checklist but not particularly novel or complex.
