 ## Why Separate package.json Files?
 
-Some integrations need to be tested against specific versions of their underlying SDKs:
+Some integrations need isolated test infrastructure for their underlying SDKs or framework integrations:
 
-- **AI SDK v4 vs v5**: Breaking changes between major versions require separate test environments
-- **Claude Agent SDK**: Has its own versioning independent of Anthropic's main SDK
