Review a spec-update branch for a generated client package (e.g., document-grounding, prompt-registry). Compares the updated generated client against main, classifies every breaking change by consumer impact, creates [compat] changesets for each breaking change, fixes or creates backward-compat patches when parameter order shifts, and adds apply-patches support when the package lacks it. Use this skill whenever you're on a spec-update/* branch, have just run pnpm generate, or want to audit what a spec update broke for downstream consumers.
