    (description
     "kaagum is a tiny, security-focused AI agent written in Guile with
minimal dependencies. Kaagum works with any LLM that provides an
OpenAI-compatible API.

kaagum runs tool calls securely using containers and capability-based
access. Tool calls have limited or no access to the filesystem and to
the network. Capabilities allow network access to be controlled with
fine granularity. Containers are implemented using Guix's container
API.

kaagum offers no user interface on its own. Instead, it speaks
the @acronym{ACP, Agent Client Protocol} and allows you to use any
compatible user interface of your choice.")
