Hermes has two slash-command surfaces, both driven by a central COMMAND_REGISTRY in hermes_cli/commands.py:
- Interactive CLI slash commands — dispatched by
cli.py, with autocomplete from the registry
- Messaging slash commands — dispatched by
gateway/run.py, with help text and platform menus generated from the registry
Installed skills are also exposed as dynamic slash commands on both surfaces. That includes bundled skills like /plan, which opens plan mode and saves markdown plans under .hermes/plans/ relative to the active workspace/backend working directory.
Interactive CLI slash commands
Type / in the CLI to open the autocomplete menu. Built-in commands are case-insensitive.
Session
| Command | Description |
|---|
/new | Start a new conversation (reset history) |
/reset | Reset conversation only (keep screen) |
/clear | Clear screen and reset conversation (fresh start) |
/history | Show conversation history |
/save | Save the current conversation |
/retry | Retry the last message (resend to agent) |
/undo | Remove the last user/assistant exchange |
/title | Set a title for the current session (usage: /title My Session Name) |
/compress | Manually compress conversation context (flush memories + summarize) |
/rollback | List or restore filesystem checkpoints (usage: /rollback [number]) |
/background <prompt> | Run a prompt in a separate background session. The agent processes your prompt independently — your current session stays free for other work. Results appear as a panel when the task finishes. See CLI Background Sessions. |
/plan [request] | Load the bundled plan skill to write a markdown plan instead of executing the work. Plans are saved under .hermes/plans/ relative to the active workspace/backend working directory. |

/toolsets | List available toolsets |
/browser [connect|disconnect|status] | Manage local Chrome CDP connection. connect attaches browser tools to a running Chrome instance (default: ws://localhost:9222). disconnect detaches. status shows current connection. Auto-launches Chrome if no debugger is detected. |

Quick commands
User-defined quick commands from quick_commands in ~/.hermes/config.yaml are also available as slash commands. These are resolved at dispatch time, not shown in the built-in autocomplete/help tables.
