Advises on API versioning strategies, designs deprecation flows, generates migration guides, and handles breaking vs non-breaking change classification. Use whenever the user asks about API versioning, "how to version my API", "URI vs header versioning", "breaking changes", "backward compatibility", "API deprecation", "sunset a version", "migrate from v1 to v2", or "semver for APIs".
