fbd70b73d4 fix(fireworks): preserve malformed tool arguments as diagnostic JSON (#40818)
`ChatFireworks` can replay historical tool calls with malformed or
non-object JSON arguments without forwarding invalid argument strings to
Fireworks.

---

Fireworks rejects conversation history containing malformed or
non-object tool-call arguments, preventing an agent from recovering on
its next turn.

Wrap these arguments in a JSON object under
`__invalid_tool_call_arguments` when serializing history, preserving the
original payload, call IDs, and tool-result pairing. Apply this to
parsed and raw tool-call history without mutating messages or executing
repaired arguments; valid object strings stay unchanged.

View all LangChain integrations packages

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
model-profiles/   # Model capability profiles and CLI (`langchain-model-profiles`)
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.
