When authoring AI/LLM tutorials in Jupyter notebooks, ensure dependency installation is done with correct notebook syntax and that nearby explanatory text is unambiguous. - Use Jupyter magics for installs inside cells (not commented shell commands or bare `pip` lines). - Keep documentation wording precise when describing session/message history behavior. Example: ```python # In a notebook cell (ipynb), use the magic: %pip install langchain_community # And keep narrative wording clear when describing state: # "...wraps the model and adds to this message history..." ```
