Use the GitHub MCP tools to edit the `mcpmark-eval/claude-code` repository.

1. On the `main` branch, add a new file `docs/TERMINAL_SHORTCUTS.md` containing exactly:

```
# Terminal Shortcuts

- `claude plan`: Outline the next steps before making edits.
- `claude apply`: Run the plan and apply the queued changes.
- `claude check`: Re-run relevant tests or linters to validate the edits.
```

2. Commit with the message `docs: add terminal shortcuts reference` and push directly to `main`.
