Design and review the project's CLI commands so they follow the modular router-plus-libexec pattern with consistent help, validation, and exit codes. Use when adding a new subcommand to `pi-usb-backup`, modifying an existing one, or reviewing command-line UX.

Design and maintain the single canonical one-line installer for this repository. Use when changing OS package setup, Raspberry Pi bootstrap steps, managed scripts, install docs, or legacy-path cleanup behavior.

Complete unit test branch coverage for a specific test file in any package under packages/. Use when asked to raise coverage to all branches, inspect coverage reports under the target package coverage directory, run only the target test file with pnpm from that package directory, add justified istanbul ignore comments for defensive branches that cannot be covered, and ask for confirmation before removing or changing production logic that appears unnecessary.
