Managing Sessions in Claude Code: /rewind, /rename, and More
A Claude Code session holds your conversation, your files, and your task. A handful of commands — /rewind to undo, /rename to find, /clear and /compact to stay lean — turn a runaway chat into workspaces you control. Here's each one, with a practice sample.
