[dependabot]

Bumps @langchain/core from 0.3.78 to 1.1.36.

Release notes

Sourced from @​langchain/core's releases.

@​langchain/core@​1.1.36

Patch Changes

• #10512 bbbfea1 Thanks @​hntrl! - fix(core): fix streaming chunk merge for providers without index on tool call deltas

  _mergeLists now falls back to id-based matching when items don't have an index field. Previously, providers routing through the OpenAI-compatible API without index on streaming tool call deltas (e.g. Anthropic models via ChatOpenAI) would accumulate hundreds of individual raw deltas in tool_call_chunks and additional_kwargs.tool_calls instead of merging them into a single entry per tool call. In a real trace with 3 concurrent subagents, this caused a single AI message to balloon from ~4KB to 146KB -- with 826 uncollapsed streaming fragments carrying a few bytes each.

  Also fixes SystemMessage.concat() which used ...this to spread all instance properties (including lc_kwargs) into the new constructor, causing each chained concat() call to nest one level deeper. After 7 middleware concat() calls (typical in deepagents), a 7KB system prompt would serialize to 81KB due to content being duplicated at every nesting level.

@​langchain/core@​1.1.35

Patch Changes

• #10327 5dc11b5 Thanks @​hntrl! - fix(core): replace exported zod type references with structural duck-type interfaces to fix TypeScript OOM

  Replaces all exported Zod type references (z3.ZodType, z4.$ZodType, etc.) in @langchain/core's public API with minimal structural ("duck-type") interfaces. This prevents TypeScript from performing expensive deep structural comparisons (~3,400+ lines of mutually recursive generics) when downstream packages resolve a different Zod version than @langchain/core, which was causing OOM crashes and unresponsive language servers in monorepo setups.

• #10433 7af0b65 Thanks @​tanushree-sharma! - feat: Add LangSmith integration metadata to createAgent and initChatModel

@​langchain/core@​1.1.34

Patch Changes

• #10312 bfb7944 Thanks @​jacoblee93! - feat(core): Add all invocation params as part of metadata

@​langchain/core@​1.1.33

Patch Changes

• #10412 6db417b Thanks @​pawel-twardziak! - fix(core): respect timeout option in streamEvents v2

• #10424 d69dfcc Thanks @​pawel-twardziak! - fix(core): preserve multimodal content in getBufferString as placeholders

@​langchain/core@​1.1.32

Patch Changes

• #10330 26488b5 Thanks @​hntrl! - fix(core): treat empty string tool call chunk IDs as missing during merge

  Fixed _mergeLists in message base to treat empty string "" IDs the same as null/undefined when merging tool call chunks. This fixes old completions-style streaming where follow-up chunks carry id: "" instead of undefined, which previously prevented chunks from being merged by index.

• #10167 ca826f6 Thanks @​colifran! - feat: implement type inference for tool streams

• #10334 a602c42 Thanks @​maahir30! - fix(core): add JSDoc docstrings to fakeModel builder API and export FakeBuiltModel

• #10254 db7d017 Thanks @​pawel-twardziak! - fix(core): preserve thoughtSignature in array content during streaming with thinking models

@​langchain/core@​1.1.31

Patch Changes

• #10271 7373b4c Thanks @​jacoblee93! - feat(core): Use uuid7 instead of v4 for generating run ids

• #10262 b0175a5 Thanks @​maahir30! - fix: Move fakeModel from utils/testing to testing namespace move to updated namespace
