📄 Description

Overview

Adds documentation for langchain-capsule, a LangChain integration that lets agents safely execute Python and JavaScript code in isolated WebAssembly sandboxes.

Two execution modes are covered:

  • Stateless tools (CapsulePythonTool, CapsuleJSTool) — each call runs in a fresh sandbox
  • Session-based REPL tools (CapsulePythonREPLTool, CapsuleJSREPLTool) — variables and state persist across calls, with support for file import/export

Type of change

Type: New documentation page

Additional notes

langchain-capsule is a community-maintained package (PyPI, GitHub) built on top of Capsule, a WebAssembly-based sandboxing runtime.
