Help
Claude Code Rust has two built-in help paths:
/help
/docs <topic>
/help opens the fullscreen Help tab. Use it when you want navigable in-app help without adding a message to the chat transcript.
/docs renders live help into the chat. Use it when you want the current commands, shortcuts, modes, models, or subagents copied into the conversation as reference material.
Fullscreen Help
The fullscreen Help tab has three sections:
| Section | Shows |
|---|---|
| Shortcuts | Keyboard shortcuts for the current app state and focused UI context. |
| Commands | App-owned slash commands plus slash commands advertised by the active SDK session. |
| Subagents | Subagents advertised by the active SDK session, including model labels when provided. |
Use Left and Right to switch Help sections. Use Up and Down to move through the visible rows in the active section.
The Shortcuts section is state-sensitive. It changes depending on whether focus is in chat input, autocomplete, an inline permission prompt, an inline question, or a blocked state such as connecting or command-pending.
The Commands and Subagents sections are also session-sensitive. While the app is connecting, they show loading rows. If the active session does not advertise SDK commands or subagents, the Help tab shows an empty-state row instead of inventing unavailable entries.
In-Chat Docs
| Command | Shows |
|---|---|
/docs mode | Current and available session modes. |
/docs models | Models advertised by the active session. |
/docs shortcuts | Keyboard shortcuts for the current app state. |
/docs commands | App-owned and SDK-advertised slash commands. |
/docs agents | Subagents advertised by the active session. |
/docs covers two topics that are not sections in the fullscreen Help tab: mode and models. Those topics are based on the active session’s advertised modes and models.
The /docs output is based on the running app state. It can differ from this manual when the active session advertises different models, modes, commands, or agents.
