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

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

3. 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

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

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

5. The script prints the new session ID (the `New session: <id>` line). Give the user the exact command to resume it directly, no picker needed:

   claude --resume <new-session-id>

The script automatically appends a reference to the original conversation at the end of the cloned file. (The new session is also marked `[HALF-CLONE <timestamp>]`, e.g. `[HALF-CLONE Jan 7 14:30]`, so `claude -r` and picking it works as a fallback.)
