Put Standing Context in a Claude Project
Using a Claude Project to hold the context you'd otherwise paste every time — reference docs, instructions, style, and background — so every chat in the project starts already informed.
Best practice
Put Your Source of Truth in Project Knowledge
A Projects habit: load the stable reference material a body of work depends on — style guide, product facts, key docs, decisions — into the project's knowledge once, so every chat in that project starts already knowing it, instead of you re-pasting the same context each time.
