SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Building chat interfaces in Streamlit often requires boilerplate to manage message history, user prompts, and streaming responses. This skill provides a ready-to-use pattern for creating conversational UIs that can be embedded in Streamlit apps, reducing development time and ensuring consistency.

Core Features & Use Cases

  • Streaming chat: render assistant responses token-by-token to create a smooth user experience.
  • Message history: maintain a persistent conversation log across sessions.
  • UI primitives: leverage st.chat_message and st.chat_input for a clean, native Streamlit chat UI.
  • Use Case: prototype customer support chat or an interactive tutor inside a Streamlit app.

Quick Start

Create a Streamlit app that uses st.chat_message and st.chat_input to build a live, streaming chat UI with message history and simple AI responses.
