%description
A complete toolkit for connecting 'R' environments with Large Language
Models (LLMs). Provides utilities for describing 'R' objects, package
documentation, and workspace state in plain text formats optimized for LLM
consumption. Supports multiple workflows: interactive copy-paste to
external chat interfaces, programmatic tool registration with 'ellmer'
chat clients, batteries-included chat applications via 'shinychat', and
exposure to external coding agents through the Model Context Protocol.
Project configuration files enable stable, repeatable conversations with
project-specific context and preferred LLM settings.
