"""Agent toolkits contain integrations with various resources and services.

LangChain has a large ecosystem of integrations with various external resources
like local and remote file systems, APIs and databases.

These integrations allow developers to create versatile applications that combine the
power of LLMs with the ability to access, interact with and manipulate external
resources.

When developing an application, developers should inspect the capabilities and
permissions of the tools that underlie the given agent toolkit, and determine
whether permissions of the given toolkit are appropriate for the application.

See https://docs.langchain.com/oss/python/security-policy for more information.
