Maintainable documentation hygiene

Documentation should be kept authoritative and maintainable: use stable links, avoid recommending deprecated APIs, and remove misleading/ineffective documentation details.

Apply it as follows:

• Prefer stable/canonical URLs (often relative) for “view tutorial” links; don’t pin to a specific external commit hash.
• Keep examples focused on the intended surface area. If documenting a tool, show tool usage (e.g., tool.invoke(...)) rather than agent-creation workflows.
• Remove or avoid examples of deprecated functionality.
• Don’t document schema/config values that are ineffective for the given type (e.g., an array default that provides no value in JSON Schema).

Example (tool-only, non-deprecated usage):

from langchain_desearch.tools import DesearchTool

tool = DesearchTool()
result = tool.invoke({"query": "LLM RAG best practices"})
print(result)
