clashtui

Use when generating a new sing-box configuration file from scratch, when asked to create a sing-box client or server config, when setting up a TUN-based proxy client with DNS/route rules, or when generating a clashtui sing-box template with ${} placeholders.

Use when migrating sing-box configuration files between versions, when `sing-box check` reports deprecated fields or validation errors after an upgrade, or when a config written for an older sing-box version fails to work with a newer version.
