The 'ai' package version in the example (^5.0.68) is lower than the version in the main package.json (^5.0.113). These versions should be aligned to ensure consistent behavior across the project and avoid potential compatibility issues.

Suggested change

	"ai": "^5.0.68",
	"ai": "^5.0.113",

[Copilot]

The 'ai' package is added as a direct dependency, but it appears to be used by consumers of this SDK rather than by the SDK itself internally. Consider whether this should be a peerDependency instead to allow consumers to manage their own version of the 'ai' package and avoid potential version conflicts.
