Forking Sessions

Forking Sessions allow you to resume a previous session without affecting the original session. Forking creates a new session ID while preserving the conversation history up to that point.

• claude --continue / claude --resume append to the same session (session continuity).
• claude --resume abc123 --fork-session forks: creates a new session (new ID) branching from any point in the original, without altering it.
