Slash command reference

Slash commands are interactive terminal user interface (TUI) controls, not shell subcommands. The registry is assembled at startup from built-in commands plus whatever the loaded plugins and extensions register.

How do I find a command or keybinding?

Type / in the prompt to list the registry active in the current session, and /hotkeys to read the resolved terminal key map. Autocomplete narrows the list as you type, so it reports the current release, mode, and extension set rather than a published snapshot.

Which subsystems have their own commands?

Subsystem	Entry point
Models and routing	/model
Sessions and history	/session, /resume, /tree, /branch, /fork, /compact, /export
F5 Distributed Cloud	/context, /namespace, /manifest, /validate, /diff, /apply, /get, /create, /delete
Capabilities	/tools, /agents, /plugin, /extensions, /mcp
Session state	/settings, /hotkeys, /memory, /usage, /plan

/context status, /mcp list, and /plugin list report the current state of those subsystems without changing anything.

Slash commands are resolved from the active built-in, extension, plugin, and project capability set, so /help is the complete lookup surface for the running session. Keybindings depend on the active component: a modal selector consumes keys before the prompt editor, and global actions apply only when no focused surface overrides them. If a shortcut differs from this page, record the xcsh version, active modal, and /help entry before filing a defect.
