Open the extensions modal tabs in Grok Build

/hooks, /plugins, /skills, /mcps, and /marketplace open the same extensions modal — each command pre-selects a different tab. Official: Modes and Commands, Skills, Plugins & Marketplaces.

Tab commands

Command	Tab it opens
/hooks	Hooks
/plugins	Plugins
/skills	Skills
/mcps	MCP servers
/marketplace	Marketplace

Switch tabs inside the modal after any of those commands. On VS Code-family terminals, Ctrl+L does not open extensions — type /plugins (or another tab command) instead; see keyboard shortcuts.

What each tab is for

Tab	Use it to
Hooks	Inspect loaded hooks; project hooks still need /hooks-trust or --trust — Use hooks
Plugins	Enable, disable, or browse installed plugins — Skills and plugins
Skills	Review discovered skills (including user-invocable slash commands)
MCP	Manage MCP servers — Add MCP servers
Marketplace	Browse and install from configured marketplace sources — Open marketplace

grok inspect lists what the CLI discovers for the current directory (rules, skills, plugins, hooks, MCP) without opening the TUI.

Pitfalls

• Treating each slash command as a separate window — they share one modal.
• Expecting project hooks to run before trust — grant /hooks-trust first.
• Looking for a Ctrl+L extensions shortcut inside VS Code / Cursor / Windsurf / Zed terminals — use the slash commands.
