half-clone（半克隆）

Clone the later half of the current conversation, discarding earlier context to reduce token usage while preserving recent work.

Steps:

1. Get the current session ID and project path: tail -1 ~/.claude/history.jsonl | jq -r '[.sessionId,.project] | @tsv'
2. Find half-clone-conversation.sh with bash: find ~/.claude -name "half-clone-conversation.sh" 2>/dev/null | sort -V | tail -1

- This finds the script whether installed via plugin or manual symlink - Uses version sort to prefer the latest version if multiple exist

1. Preview the conversation to verify the session ID: <script-path> --preview <session-id> <project-path>

- Check that the first and last messages match the current conversation

1. Run the clone: <script-path> <session-id> <project-path>

- Always pass the project path from the history entry, not the current working directory

1. Tell the user they can access the half-cloned conversation with claude -r and look for the one marked [HALF-CLONE <timestamp>] (e.g., [HALF-CLONE Jan 7 14:30]). The script automatically appends a reference to the original conversation at the end of the cloned file.
