- Implemented automatic session logging, saving conversation trajectories to the `logs/` directory in JSON format, with each session having a unique identifier. - Updated the CLI to display the session ID in the welcome banner for easy reference. - Introduced an interactive sudo password prompt in CLI mode, allowing users to enter their password with a 45-second timeout, enhancing user experience during command execution. - Documented session logging and interactive sudo features in `README.md`, `cli.md`, and `cli-config.yaml.example` for better user guidance.

# CLI
|
||
|
||
The Hermes Agent CLI provides an interactive terminal interface for working with the agent.
|
||
|
||
## Running the CLI
|
||
|
||
```bash
|
||
# Basic usage
|
||
./hermes
|
||
|
||
# With specific model
|
||
./hermes --model "anthropic/claude-sonnet-4"
|
||
|
||
# With specific toolsets
|
||
./hermes --toolsets "web,terminal,skills"
|
||
|
||
# Verbose mode
|
||
./hermes --verbose
|
||
```
|
||
|
||
## Architecture
|
||
|
||
The CLI is implemented in `cli.py` and uses:
|
||
|
||
- **Rich** - Welcome banner with ASCII art and styled panels
|
||
- **prompt_toolkit** - Fixed input area with command history
|
||
- **KawaiiSpinner** - Animated feedback during operations
|
||
|
||
```

## Configuration
|
||
|
||
The CLI is configured via `cli-config.yaml`. Copy from `cli-config.yaml.example`:
|
||
|
||
```bash
|
||
cp cli-config.yaml.example cli-config.yaml
|
||
```
|
||
|
||
### Model Configuration
|
||
|
||
```yaml
|
||
model:
|
||
default: "anthropic/claude-opus-4.5"
|
||
base_url: "https://openrouter.ai/api/v1"
|
||
```
|
||
|
||
### Terminal Configuration
|
||
|
||
The CLI supports multiple terminal backends:
|
||
|
||
```yaml
|
||
# Local execution (default)
|
||
terminal:
|
||
env_type: "local"
|
||
cwd: "." # Current directory
|
||
|
||
# SSH remote execution (sandboxed - agent can't touch its own code)
|
||
terminal:
|
||
env_type: "ssh"
|
||
cwd: "/home/myuser/project"
|
||
ssh_host: "my-server.example.com"
|
||
ssh_user: "myuser"
|
||
ssh_key: "~/.ssh/id_rsa"
|
||
|
||
# Docker container
|
||
terminal:
|
||
env_type: "docker"
|
||
docker_image: "python:3.11"
|
||
|
||
# Singularity/Apptainer (HPC)
|
||
terminal:
|
||
env_type: "singularity"
|
||
singularity_image: "docker://python:3.11"
|
||
|
||
# Modal cloud
|
||
terminal:
|
||
env_type: "modal"
|
||
modal_image: "python:3.11"
|
||
```
|
||
|
||
### Sudo Support
|
||
|
||
The CLI supports interactive sudo prompts:
|
||
|
||
```
|
||
┌──────────────────────────────────────────────────────────┐
|
||
│ 🔐 SUDO PASSWORD REQUIRED │
|
||
├──────────────────────────────────────────────────────────┤
|
||
│ Enter password below (input is hidden), or: │
|
||
│ • Press Enter to skip (command fails gracefully) │
|
||
│ • Wait 45s to auto-skip │
|
||
└──────────────────────────────────────────────────────────┘
|
||
|
||
Password (hidden):
|
||
```
|
||
|
||
**Options:**
|
||
- **Interactive**: Leave `sudo_password` unset - you'll be prompted when needed
|
||
- **Configured**: Set `sudo_password` in `cli-config.yaml` to auto-fill
|
||
- **Environment**: Set `SUDO_PASSWORD` in `.env` for all runs
|
||
|
||
Password is cached for the session once entered.
|
||
|
||
### Toolsets
|
||
|
||
Control which tools are available:
|
||
|
||
```yaml
|
||
# Enable all tools
|
||
toolsets:
|
||
- all
|
||
|
||
# Or enable specific toolsets
|
||
toolsets:
|
||
- web
|
||
- terminal
|
||
- skills
|
||
```
|
||
|
||
Available toolsets: `web`, `search`, `terminal`, `browser`, `vision`, `image_gen`, `skills`, `moa`, `debugging`, `safe`
|
||
|
||
### Personalities
|
||
|
||
Predefined personalities for the `/personality` command:
|
||
|
||
```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!
|
||
```
|
||
|
||
Built-in personalities:
|
||
- `helpful`, `concise`, `technical`, `creative`, `teacher`
|
||
- `kawaii`, `catgirl`, `pirate`, `shakespeare`, `surfer`
|
||
- `noir`, `uwu`, `philosopher`, `hype`
|
||
|
||
## Animated Feedback
|
||
|
||
The CLI provides animated feedback during operations:
|
||
|
||
### Thinking Animation
|
||
|
||
During API calls, shows animated spinner with thinking verbs:
|
||
```
|
||
◜ (｡•́︿•̀｡) pondering... (1.2s)
|
||
◠ (⊙_⊙) contemplating... (2.4s)
|
||
✧٩(ˊᗜˋ*)و✧ got it! (3.1s)
|
||
```
|
||
|
||
### Tool Execution Animation
|
||
|
||
Each tool type has unique animations:
|
||
```
|
||
⠋ (◕‿◕✿) 🔍 web_search... (0.8s)
|
||
▅ (≧◡≦) 💻 terminal... (1.2s)
|
||
🌓 (★ω★) 🌐 browser_navigate... (2.1s)
|
||
✧ (✿◠‿◠) 🎨 image_generate... (4.5s)
|
||
```
|
||
|
||
## Multi-line Input
|
||
|
||
For multi-line input, end a line with `\` to continue:
|
||
|
||
```
|
||
❯ Write a function that:\
|
||
1. Takes a list of numbers\
|
||
2. Returns the sum
|
||
```
|
||
|
||
## Environment Variable Priority
|
||
|
||
For terminal settings, `cli-config.yaml` takes precedence over `.env`:
|
||
|
||
1. `cli-config.yaml` (highest priority in CLI)
|
||
2. `.env` file
|
||
3. System environment variables
|
||
4. Default values
|
||
|
||
This allows you to have different terminal configs for CLI vs batch processing.
|
||
|
||
## Session Management
|
||
|
||
- **History**: Command history is saved to `~/.hermes_history`
|
||
- **Conversations**: Use `/save` to export conversations
|
||
- **Reset**: Use `/clear` for full reset, `/reset` to just clear history
|
||
- **Session Logs**: Every session automatically logs to `logs/session_{session_id}.json`
|
||
|
||
### Session Logging
|
||
|
||
Sessions are automatically logged to the `logs/` directory:
|
||
|
||
```
|
||
logs/
|
||
├── session_20260201_143052_a1b2c3.json
|
||
├── session_20260201_150217_d4e5f6.json
|
||
└── ...
|
||
```
|
||
|
||
The session ID is displayed in the welcome banner and follows the format: `YYYYMMDD_HHMMSS_UUID`.
|
||
|
||
Log files contain:
|
||
- Full conversation history in trajectory format
|
||
- Timestamps for session start and last update
|
||
- Model and message count metadata
|
||
|
||
This is useful for:
|
||
- Debugging agent behavior
|
||
- Replaying conversations
|
||
- Training data inspection
|
||
|
||
## Quiet Mode
|
||
|
||
The CLI runs in "quiet mode" (`HERMES_QUIET=1`), which:
|
||
- Suppresses verbose logging from tools
|
||
- Enables kawaii-style animated feedback
|
||
- Hides terminal environment warnings
|
||
- Keeps output clean and user-friendly
|
||
|
||
For verbose output (debugging), use:
|
||
```bash
|
||
./hermes --verbose
|
||
```
