Minor Changes

• Breaking: AG-UI client-to-server compliance. (#511)

  @tanstack/ai-client now POSTs an AG-UI RunAgentInput request body and @tanstack/ai server endpoints must use the new chatParamsFromRequestBody + mergeAgentTools helpers. Upgrade both packages together.

  Highlights:

  • Wire format: {threadId, runId, state, messages, tools, context, forwardedProps} (per AG-UI 0.0.52 RunAgentInputSchema) instead of {messages, data}.
  • New server helpers exported from @tanstack/ai: chatParamsFromRequestBody, mergeAgentTools.
  • chat() accepts threadId, runId, parentRunId as optional fields for AG-UI run correlation.
  • ChatClient accepts threadId option; auto-generates and persists per session if omitted; fresh runId per send.
  • Client tools auto-advertised to the server via RunAgentInput.tools.
  • Foreign AG-UI clients can hit a TanStack server: developer collapses to system, reasoning/activity drop.

  See docs/migration/ag-ui-compliance.md for full migration steps.

Patch Changes

• fix(ai): infer Zod-typed outputSchema instead of collapsing to unknown (#563)

  chat({ outputSchema: zodSchema }) previously returned Promise<unknown> (and
  StructuredOutputCompleteEvent<T> resolved with T = unknown) because
  InferSchemaType only matched StandardJSONSchemaV1. Zod's core $ZodType
  declares ~standard as StandardSchemaV1.Props — without a type-level
  jsonSchema converter — so Zod schemas (and any other library that exposes
  only the Standard Schema validator surface to the type checker) fell through
  to unknown, forcing callers to either cast or run a redundant schema.parse().

  SchemaInput now also accepts StandardSchemaV1<any, any>, and
  InferSchemaType recovers the input type from that branch when the
  JSON-schema branch doesn't match. The runtime path is unchanged for Zod /
  ArkType / Valibot (convertSchemaToJsonSchema still detects the runtime
  ~standard.jsonSchema converter); only the static types are widened.

  convertSchemaToJsonSchema now throws an actionable error when given a
  Standard Schema validator that lacks a JSON-schema converter, instead of
  silently shipping the raw { '~standard': ... } object to the LLM provider.
