A Pydantic model class has no JSON form, so the field was stringified. Ask the schema for its own JSON schema instead -- `model_json_schema()` for a v2 class, `schema()` for a v1 one -- so every accepted `args_schema` form dumps to the shape the dict form already has, and the dumped schema validates back into a tool. A dict schema is still returned unchanged. Cached per schema class: pydantic does not memoize schema generation, and it costs ~500x the rest of the dump, which tracing would pay on every run. A schema holding an arbitrary type has no JSON schema at all, so those still fall back to the repr rather than raising. 12-tool payload: 0.140 ms on master, 0.023 ms here.

This repository is structured as a monorepo, with various packages located in this libs/ directory. Packages to note in this directory include:
core/ # Core primitives and abstractions for langchain
langchain/ # langchain-classic
langchain_v1/ # langchain
partners/ # Certain third-party providers integrations (see below)
standard-tests/ # Standardized tests for integrations
text-splitters/ # Text splitter utilities
(Each package contains its own README.md file with specific details about that package.)
Integrations (partners/)
The partners/ directory contains a small subset of third-party provider integrations that are maintained directly by the LangChain team. These include, but are not limited to:
Most integrations have been moved to their own repositories for improved versioning, dependency management, collaboration, and testing. This includes packages from popular providers such as Google and AWS. Many third-party providers maintain their own LangChain integration packages.
