  2. 02Finds the latest half-clone script
  3. 03Previews the conversation before cloning
  4. 04Clones the later half of the conversation
  5. 05Provides a direct resume command

Details

From the project README

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.)
