Claude Code does not treat memory as one single feature, because its behavior is shaped by a combination of persistent instruction files, automatically learned preferences, and live context gathered from the repository during the active session. That distinction matters because many users describe everything Claude remembers as memory, while Anthropic’s own documentation separates manual instruction layers from automatic memory and from the project context that Claude retriev
