# Quarter Clone

Quarter Clone clones the last quarter of the current conversation to reduce token usage while preserving recent work. Use it when you want to discard old context and continue from the most recent portion.

**Install:**

```bash
npx degit https://github.com/ykdojo/claude-code-tips/tree/main/skills/quarter-clone ~/.claude/skills/quarter-clone
```

## README

Clone the last quarter 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
   - The same script handles both half and quarter cloning; `--quarter` selects quarter mode
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> --quarter <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 `[QUARTER-CLONE <timestamp>]`, e.g. `[QUARTER-CLONE Jan 7 14:30]`, so `claude -r` and picking it works as a fallback.)
