Claude Code and Remote Control can now fork a conversation's history, optionally from a specific point, into a brand-new session.
What
- A new control-request subtype,
fork_conversation, lets a host or SDK client fork the current session's conversation — optionally truncated to a specific target message — into a brand-new session created via the SDK backend, seeded with the prior message history and tagged for provenance verification. - Remote Control gains a
fork_conversationtool implementing this: it can fork from a specific message (target_message_uuid) or the whole transcript, writes a size-capped JSON "seed" file to disk, and uploads/attaches it to the newly created session, which can adopt, discard, or re-verify that seed on session start. - Failure cases are surfaced with specific reasons: "turn running", "commands queued", "prompt pending", "target not found", "history suppressed".
Why This lets you branch a conversation into a separate session (for example, to explore an alternative direction without losing the original), whether you're driving Claude Code through the SDK or through Remote Control.
