1	CLI Interface	Master the Hermes Agent terminal interface — commands, keybindings, personalities, and more

CLI Interface

Hermes Agent's CLI is a full terminal user interface (TUI) — not a web UI. It features multiline editing, slash-command autocomplete, conversation history, interrupt-and-redirect, and streaming tool output. Built for people who live in the terminal.

Running the CLI

# Start an interactive session (default)
hermes

# Single query mode (non-interactive)
hermes chat -q "Hello"

# With a specific model
hermes chat --model "anthropic/claude-sonnet-4"

# With a specific provider
hermes chat --provider nous        # Use Nous Portal
hermes chat --provider openrouter  # Force OpenRouter

# With specific toolsets
hermes chat --toolsets "web,terminal,skills"

# Resume previous sessions
hermes --continue             # Resume the most recent CLI session (-c)
hermes --resume <session_id>  # Resume a specific session by ID (-r)

# Verbose mode (debug output)
hermes chat --verbose

# Isolated git worktree (for running multiple agents in parallel)
hermes -w                         # Interactive mode in worktree
hermes -w -q "Fix issue #123"     # Single query in worktree

The welcome banner shows your model, terminal backend, working directory, available tools, and installed skills at a glance.

Session Resume Display

When resuming a previous session (hermes -c or hermes --resume <id>), a "Previous Conversation" panel appears between the banner and the input prompt, showing a compact recap of the conversation history. See Sessions — Conversation Recap on Resume for details and configuration.

Keybindings

Key	Action
`Enter`	Send message
`Alt+Enter` or `Ctrl+J`	New line (multi-line input)
`Alt+V`	Paste an image from the clipboard when supported by the terminal
`Ctrl+V`	Paste text and opportunistically attach clipboard images
`Ctrl+B`	Start/stop voice recording when voice mode is enabled (`voice.record_key`, default: `ctrl+b`)
`Ctrl+C`	Interrupt agent (double-press within 2s to force exit)
`Ctrl+D`	Exit
`Tab`	Autocomplete slash commands

Slash Commands

Type / to see the autocomplete dropdown. Hermes supports a large set of CLI slash commands, dynamic skill commands, and user-defined quick commands.

Common examples:

Command	Description
`/help`	Show command help
`/model`	Show or change the current model
`/tools`	List currently available tools
`/skills browse`	Browse the skills hub and official optional skills
`/background <prompt>`	Run a prompt in a separate background session
`/skin`	Show or switch the active CLI skin
`/voice on`	Enable CLI voice mode (press `Ctrl+B` to record)
`/voice tts`	Toggle spoken playback for Hermes replies
`/reasoning high`	Increase reasoning effort
`/title My Session`	Name the current session

For the full built-in CLI and messaging lists, see Slash Commands Reference.

For setup, providers, silence tuning, and messaging/Discord voice usage, see Voice Mode.

:::tip Commands are case-insensitive — /HELP works the same as /help. Installed skills also become slash commands automatically. :::

Quick Commands

You can define custom commands that run shell commands instantly without invoking the LLM. These work in both the CLI and messaging platforms (Telegram, Discord, etc.).

# ~/.hermes/config.yaml
quick_commands:
  status:
    type: exec
    command: systemctl status hermes-agent
  gpu:
    type: exec
    command: nvidia-smi --query-gpu=utilization.gpu,memory.used --format=csv,noheader

Then type /status or /gpu in any chat. See the Configuration guide for more examples.

Skill Slash Commands

Every installed skill in ~/.hermes/skills/ is automatically registered as a slash command. The skill name becomes the command:

/gif-search funny cats
/axolotl help me fine-tune Llama 3 on my dataset
/github-pr-workflow create a PR for the auth refactor

# Just the skill name loads it and lets the agent ask what you need:
/excalidraw

Personalities

Set a predefined personality to change the agent's tone:

/personality pirate
/personality kawaii
/personality concise

Built-in personalities include: helpful, concise, technical, creative, teacher, kawaii, catgirl, pirate, shakespeare, surfer, noir, uwu, philosopher, hype.

You can also define custom personalities in ~/.hermes/config.yaml:

agent:
  personalities:
    helpful: "You are a helpful, friendly AI assistant."
    kawaii: "You are a kawaii assistant! Use cute expressions..."
    pirate: "Arrr! Ye be talkin' to Captain Hermes..."
    # Add your own!

Multi-line Input

There are two ways to enter multi-line messages:

Alt+Enter or Ctrl+J — inserts a new line
Backslash continuation — end a line with \ to continue:

❯ Write a function that:\
  1. Takes a list of numbers\
  2. Returns the sum

:::info Pasting multi-line text is supported — use Alt+Enter or Ctrl+J to insert newlines, or simply paste content directly. :::

Interrupting the Agent

You can interrupt the agent at any point:

Type a new message + Enter while the agent is working — it interrupts and processes your new instructions
Ctrl+C — interrupt the current operation (press twice within 2s to force exit)
In-progress terminal commands are killed immediately (SIGTERM, then SIGKILL after 1s)
Multiple messages typed during interrupt are combined into one prompt

Tool Progress Display

The CLI shows animated feedback as the agent works:

Thinking animation (during API calls):

  ◜ (｡•́︿•̀｡) pondering... (1.2s)
  ◠ (⊙_⊙) contemplating... (2.4s)
  ✧٩(ˊᗜˋ*)و✧ got it! (3.1s)

Tool execution feed:

  ┊ 💻 terminal `ls -la` (0.3s)
  ┊ 🔍 web_search (1.2s)
  ┊ 📄 web_extract (2.1s)

Cycle through display modes with /verbose: off → new → all → verbose.

Session Management

Resuming Sessions

When you exit a CLI session, a resume command is printed:

Resume this session with:
  hermes --resume 20260225_143052_a1b2c3

Session:        20260225_143052_a1b2c3
Duration:       12m 34s
Messages:       28 (5 user, 18 tool calls)

Resume options:

hermes --continue                          # Resume the most recent CLI session
hermes -c                                  # Short form
hermes -c "my project"                     # Resume a named session (latest in lineage)
hermes --resume 20260225_143052_a1b2c3     # Resume a specific session by ID
hermes --resume "refactoring auth"         # Resume by title
hermes -r 20260225_143052_a1b2c3           # Short form

Resuming restores the full conversation history from SQLite. The agent sees all previous messages, tool calls, and responses — just as if you never left.

Use /title My Session Name inside a chat to name the current session, or hermes sessions rename <id> <title> from the command line. Use hermes sessions list to browse past sessions.

Session Storage

CLI sessions are stored in Hermes's SQLite state database under ~/.hermes/state.db. The database keeps:

session metadata (ID, title, timestamps, token counters)
message history
lineage across compressed/resumed sessions
full-text search indexes used by session_search

Some messaging adapters also keep per-platform transcript files alongside the database, but the CLI itself resumes from the SQLite session store.

Context Compression

Long conversations are automatically summarized when approaching context limits:

# In ~/.hermes/config.yaml
compression:
  enabled: true
  threshold: 0.50    # Compress at 50% of context limit by default
  summary_model: "google/gemini-3-flash-preview"  # Model used for summarization

When compression triggers, middle turns are summarized while the first 3 and last 4 turns are always preserved.

Quiet Mode

By default, the CLI runs in quiet mode which:

Suppresses verbose logging from tools
Enables kawaii-style animated feedback
Keeps output clean and user-friendly

For debug output:

hermes chat --verbose
