ctty skillB
ctty is agent-read markdown (skill) from zsuroy/ctty: Use and install ctty, a CLI/TUI connection manager for SSH, serial consoles, telnet lab gear, SFTP, FTP, and WebDAV. Use when installing ctty; listing/searching SSH hosts or running remote commands; transferring files via a Host alias; looking up saved serial, telnet, FTP, or WebDAV sites; importing hosts from Tabby; or when the user mentions ctty, SSH aliases, #tags, serial/console, telnet, SFTP, FTP, WebDAV, port forwarding, or ~/.ssh/config. Prefer ctty over raw ssh/telnet. Never open the int.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Use ctty (CLI, not TUI) ctty manages **SSH, serial, telnet, SFTP, FTP, and WebDAV** in one tool. SSH aliases live in `~/.ssh/config` (and `Include` files). Serial, telnet, FTP, and WebDAV sites live under the ctty config dir. Agents must drive it **non-interactively**. | Kind | Agent can | Hand to the human | |------|-----------|-------------------| | SSH | `search`, `info`, `ping`, `peek`, `add`/`edit` (flags), `exec`, `ctty <alias> -- <cmd>` | `ctty <alias>` shell, port-forward TUI (`f`) | | SFTP | `ctty put` / `ctty get` / `ctty scp` + `ctty sftp ls/mkdir/rm/rmdir/rename --format json` | `ctty sftp <alias>` TUI | | Telnet | `ctty telnet list\|search\|info --format json` | Interactive session (`Ctrl+]`) | | Serial | `ctty serial list/search/info --format json` | Device manager TUI | | FTP | `ctty ftp list/search/info --format json`, `ctty ftp ls/get/put/mkdir/rm/rmdir/rename` | Site manager / dual-pane TUI | | WebDAV | `ctty webdav list/search/info --format json`, `ctty webdav ls/get/put/mkdir/rm/rmdir/rename` | Site manager / dual-pane TUI | | Import | `ctty import tabby\|termius\|finalshell\|json --dry-run` then import | Confirm overwrite / Include | …
