| Install complexity | MODERATE | Moderate: pair both devices and share folders; APT requires official stable-v2 repository setup first | Easy with a supported package manager; Homebrew must already be installed for this command. Official binaries, Windows, Linux, and source options are documented. |

| Best use | Best for an individual developer or small team tracing a bug, adding a test, or implementing a bounded change with a reviewable plan and diff. Avoid broad production access or unscoped Auto-approve, and do not treat it as a replacement for tests, Git, or human review. | Best for an individual working across two computers or a small team sharing files with trusted devices. It moves folder changes instead of repeating manual copies, while keeping device and storage choices under your control. It does not replace independent backups or collaborative editing, and devices holding the files must be reachable. | For developers and small teams that want architecture and data-flow diagrams close to the repository and reviewable as text. Use it when relationships matter more than pixel-perfect placement; not for free-form marketing design or exact manual positioning. |
