---

3. HTTP Client

File: cli/client.py

Features:

• Full integration with Web API
• Token-based authentication
• Clean error handling
• Context manager support

Methods:

• request_token(email) - Request auth token
• send_message(session_id, message) - Send chat message
• get_history(session_id, limit) - Get conversation history
• list_sessions() - List all sessions
• delete_session(session_id) - Delete a session
• health_check() - Check API health

Usage:

from cli.client import LoyalCompanionClient

client = LoyalCompanionClient("http://localhost:8080", "auth_token")
response = client.send_message("session_123", "Hello!")
client.close()

# Or with context manager
with LoyalCompanionClient(url, token) as client:
    response = client.send_message(session_id, message)

---

4. Configuration Management

File: cli/config.py

Configuration stored in: ~/.lc/config.json

Settings:

{
  "api_url": "http://127.0.0.1:8080",
  "auth_token": "web:user@example.com",
  "email": "user@example.com",
  "allow_emoji": false,
  "default_session": "default",
  "auto_save": true,
  "show_mood": true,
  "show_relationship": false,
  "show_facts": false,
  "show_timestamps": false
}

Environment variables:

• LOYAL_COMPANION_API_URL - Override API URL
• LOYAL_COMPANION_TOKEN - Override auth token

Automatic creation:

• Config directory created on first run
• Config file saved automatically
• Persistent across CLI invocations

---

5. Session Management

File: cli/session.py

Sessions stored in: ~/.lc/sessions.json

Session data:

{
  "default": {
    "session_id": "cli_default_7ab5231d12eb3e88",
    "name": "default",
    "created_at": "2026-02-01T14:30:00.000000",
    "last_active": "2026-02-01T15:45:23.123456",
    "message_count": 42
  },
  "work": {
    "session_id": "cli_work_9cd1234a56ef7b90",
    "name": "work",
    "created_at": "2026-02-01T09:00:00.000000",
    "last_active": "2026-02-01T14:20:15.654321",
    "message_count": 18
  }
}

Features:

• Multiple named sessions
• Auto-generated unique session IDs
• Timestamp tracking
• Message count tracking
• Persistence across restarts

---

6. Response Formatting

File: cli/formatters.py

Two modes:

Plain Text Mode (fallback)

You: I'm feeling overwhelmed today.

Bartender: That sounds heavy. Want to sit with it for a bit?
  Mood: calm

Rich Mode (if rich library available)

• Color-coded output
• Bold text for roles
• Formatted metadata panels
• Syntax highlighting
• Better readability

Features:

• Configurable display options
• Mood information
• Relationship information
• Facts learned count
• Timestamps (optional)
• Error/info/success messages

---

7. Authentication Flow

Phase 4 approach: Same simple token as Web platform

Flow:

1. First time:

   $ lc talk
   Email address: alice@example.com
   Authenticated as alice@example.com
   Bartender is here.
   ...
   

2. Subsequent runs:

   $ lc talk
   Bartender is here.
   Resuming session 'default' (15 messages)
   ...
   

3. Token stored in: ~/.lc/config.json

4. Logout:

   $ lc auth --logout
   Authentication cleared
   

Security note:

• Token is stored in plain text in config file
• For Phase 4, token is simple: web:{email}
• In production, should use proper JWT with expiration

Comparison: CLI vs Web vs Discord

Feature	Discord	Web	CLI
Platform	Discord app	Browser	Terminal
Intimacy	LOW/MEDIUM	HIGH	HIGH
Interface	Rich (buttons, embeds)	Rich (HTML/CSS/JS)	Minimal (text)
Auth	Discord OAuth	Simple token	Simple token
Sessions	Channels/DMs	Web sessions	Named sessions
Local storage	None	localStorage	~/.lc/
Real-time	Yes (gateway)	No (polling)	No (request/response)
Formatting	Rich (markdown, emoji)	Rich (HTML)	Plain/Rich text
Offline mode	No	No	No (HTTP client)
Noise level	High (social)	Medium (UI elements)	Low (quiet)
Use case	Social bar	Quiet back room	Empty table at closing

---

Design Philosophy

Quietness

The CLI embodies the "empty table at closing time" philosophy:

✅ Quiet:

• No spinners or progress bars
• No ASCII art or banners
• No excessive logging
• Minimal output

✅ Intentional:

• Explicit commands
• Named sessions for context switching
• No automatic behaviors
• User controls everything

✅ Focused:

• Text-first interface
• No distractions
• No engagement metrics
• Pure conversation

Text-First Design

No emojis by default:

cli_allow_emoji: bool = False  # Can be enabled in config

No typing indicators:

• No "Bartender is typing..."
• Immediate response display
• No artificial delays

No seen/read receipts:

• No engagement metrics
• No pressure to respond
• Just presence

---

Known Limitations

Current (Phase 4)

1. No real-time updates:

   • Request/response only
   • No WebSocket support
   • No push notifications

2. No offline mode:

   • Requires web server running
   • Requires network connection
   • No local-only conversations

3. Simple authentication:

   • Token stored in plain text
   • No JWT expiration
   • No refresh tokens

4. No rich formatting:

   • Plain text only (unless rich library)
   • No markdown rendering in messages
   • No syntax highlighting for code blocks

5. No image support:

   • Text-only conversations
   • No image upload
   • No image viewing

6. Single user per config:

   • One email/token per machine
   • No multi-user support
   • No profile switching

To Be Addressed

Phase 5 (Enhancements):

• Add proper JWT authentication
• Add markdown rendering in terminal
• Add image viewing (ASCII art or external viewer)
• Add multi-user profiles
• Add WebSocket for real-time (optional)

---

Dependencies

Required:

• typer>=0.9.0 - CLI framework
• httpx>=0.26.0 - HTTP client

Optional:

• rich>=13.7.0 - Rich terminal formatting (recommended)

Added to requirements.txt:

# CLI Platform

Example Session

$ lc talk
Email address: alice@example.com
Authenticated as alice@example.com
Bartender is here.
Type your message and press Enter. Press Ctrl+D to end.

You: I had a rough day at work.

Bartender: Sounds like it took a lot out of you. Want to talk about what made it rough, or just let it sit?

You: My manager criticized my code review in front of the whole team.

Bartender: That's embarrassing and it sucks to be called out like that. The public part probably stung more than the criticism itself.

You: Yeah, exactly. I don't mind the feedback but why in front of everyone?

Bartender: Sounds like a power move more than a teaching moment. Did you get a chance to talk to them privately after?

You: No, I just left.

Bartender: Sometimes walking away is the right call. You don't have to process it all at once.

You: Thanks. I needed to hear that.

Bartender: Anytime. I'm here.

You: ^D
