- Both middleware share the same implementation, the only difference is one uses Claude's server-side tool definition, whereas the other one uses a generic tool definition compatible with all models - Implemented 3 execution policies (responsible for actually running the shell process) - HostExecutionPolicy runs the shell as subprocess, appropriate for already sandboxed environments, eg when run inside a dedicated docker container - CodexSandboxExecutionPolicy runs the shell using the sandbox command from the Codex CLI which implements sandboxing techniques for Linux and Mac OS. - DockerExecutionPolicy runs the shell inside a dedicated Docker container for isolation. - Implements all behaviours described in https://docs.claude.com/en/docs/agents-and-tools/tool-use/bash-tool#handle-large-outputs including timeouts, truncation, output redaction, etc --------- Co-authored-by: Sydney Runkle <54324534+sydney-runkle@users.noreply.github.com> Co-authored-by: Sydney Runkle <sydneymarierunkle@gmail.com> Co-authored-by: Eugene Yurtsev <eyurtsev@gmail.com>

Important
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.
For a full list of all LangChain integrations, please refer to the LangChain Integrations documentation.
