A marketing lead drafts a weekly product update for customers. Every week she opens a new chat and pastes in the same brand voice guide, product glossary and two example updates before asking for a draft. What is the most appropriate change?

Answer: C — Set up a Project with the guide, glossary and examples as knowledge, plus standing instructions for the update.

Pasting the same context every week signals recurring work, which a Project is built for. Its instructions and knowledge apply to every chat inside it (c). A bigger model (a) still needs the context supplied. Research (b) searches outside sources for multi-source questions and won't find her internal guide. One endless chat (d) builds up clutter and drift over many weeks.
