📄 Description

Overview

Adding documentation for langchain-w2a — a tool integration that turns W2A-enabled websites (sites serving /.well-known/agents.json) into typed LangChain tools.

W2A is an open standard for agent-readable websites — like robots.txt but for AI agents. Sites declare their skills, inputs, outputs, and auth in one JSON file.

Components:

  • W2AToolkit.from_url() — creates one typed BaseTool per skill declared in a site's agents.json
  • W2ADiscoverTool — discovers what any W2A-enabled site can do
  • W2ASkillTool — calls a specific skill on a W2A-enabled site

Type of change

Type: New documentation page

Discussed with @niilooy in the LangChain community forum:
https://forum.langchain.com/t/new-integration-langchain-w2a-langchain-tools-for-w2a-enabled-websites

Follows the standalone integration pattern from https://docs.langchain.com/oss/python/contributing/integrations-langchain
Note: Did not run docs dev locally but happy to install the toolchain and verify if needed before merge.
