LGTM. Left some minor questions. Was the suggestion to add compatibility notes related to this PR?

LGTM from my side, asked few minor questions.

Also, in documentation portal have you checked if there are any zod v3 specific examples, if yes, don't we have to migrate all to zod v4?

@KavithaSiva SAP/ai-sdk#299 makes the docs use versioned zod imports. The SDK does not seem to have many direct dependencies on zod, and none for the langchain package itself.

Regarding compatibility of toJsonSchema from langchain:

zod/v3: zod v4 and zod v3 always produce the same output
zod/v4: If the package version (npm) of the zod peer dependency used by @langchain/core does not much the package that defined the schema properties like description are dropped (e.g.@langchain/core uses zod@4/v4 and receives a zod@3/v4 schema)

I don't have experience with this, but I also noticed that the listed overloads for withStructuredOutput< do not match upstream.

…e updates

davidkna-sap · 2025-11-21T15:40:52Z

.github/dependabot.yml

I added this to ensure there is a notification for future major updates, and added grouping because the packages are tightly coupled.

Only thing that we need to update is the @modelcontextprotocol/sdk, but let's do this later once anthropic release a stable 1.23.0
