A. Claude stores them permanently across all Projects
B. The instructions guide how Claude responds every time
C. Claude ignores them unless you say “please”
D. You have to retype them for each message
Answer
B. The instructions guide how Claude responds every time
Explanation
Persistent System Prompts
When you configure instructions within a specific Claude Project, they function as a permanent baseline prompt for that exact workspace. These parameters establish strict rules for tone, formatting, and structural guidelines across every conversation you initiate inside that project. Instead of rewriting your preferences for each new chat, the AI automatically applies your foundational rules to maintain consistent, reliable outputs.
Workspace Boundaries
These behavioral directives remain strictly confined to the individual project where you set them. They do not transfer to your other workspaces or standard conversational chats. This localized setup allows you to build highly specialized environments, ensuring a coding project and a marketing project operate with completely distinct rules.
