# Kugetsu Phase 3a Installation Guide

Guide for setting up the Kugetsu Chat Agent (Phase 3a) on a new host/container.

## Prerequisites

1. **Hermes Agent** installed and configured
2. **Telegram bot** created via @BotFather
3. **kugetsu CLI** installed
4. **opencode** installed

## Step 1: Verify Hermes Installation

```bash
hermes version
hermes config show  # Check Telegram is configured
```

## Step 2: Link Skills to Hermes

```bash
# Create skill directories
mkdir -p ~/.hermes/skills/kugetsu-chat

# Link skills from kugetsu repo (adjust path as needed)
KUGEETSU_DIR="/path/to/kugetsu"  # e.g., ~/repositories/kugetsu

ln -sf "$KUGEETSU_DIR/skills/kugetsu-chat" ~/.hermes/skills/kugetsu-chat
```

## Step 3: Install Chat Agent SOUL

```bash
# Copy SOUL.md to Hermes home (this defines the Chat Agent personality)
cp "$KUGEETSU_DIR/skills/kugetsu-chat/SOUL.md" ~/.hermes/SOUL-chat.md
```

## Step 4: Verify Gateway is Running

```bash
hermes gateway status
# If stopped:
hermes gateway start
```

## Step 5: Initialize kugetsu

**WARNING:** This requires an interactive terminal (TTY) because it spawns the opencode TUI.

You must run this in an **interactive shell**, not via `ssh remote "kugetsu init"`:

```bash
# Option 1: SSH with TTY allocation
ssh -t user@host "kugetsu init"

# Option 2: Connect to existing session and run
ssh user@host
kugetsu init  # Run manually in the SSH session
```

This creates:
- **Base session** (for forking dev agents)
- **PM Agent session** (persistent coordinator, loaded with kugetsu-pm context)

If you get `Error: init requires a terminal (TTY)`, you're running via non-interactive SSH. Use `-t` flag or connect directly.

## Step 6: Verify Setup

```bash
# Check kugetsu status
kugetsu status
# Should output: ok

# List all sessions
kugetsu list
```

## Step 7: Test via Telegram

Start a conversation with your bot (@your_bot_username):

| Message | Expected |
|---------|----------|
| `hi` | Responds directly (small talk) |
| `status?` | Routes to PM Agent |
| `fix issue #5` | Routes to PM Agent |

## Troubleshooting

### kugetsu command not found
```bash
export PATH="$HOME/.local/bin:$PATH"
# Or add to ~/.bashrc
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
```

### Gateway not responding
```bash
hermes gateway restart
```

### PM agent issues
```bash
# Diagnose
kugetsu doctor

# Fix (if needed)
kugetsu doctor --fix

# Or reinitialize
kugetsu destroy --pm-agent -y
kugetsu init
```

## kugetsu Commands

| Command | Description |
|---------|-------------|
| `kugetsu init` | Initialize base + PM agent sessions |
| `kugetsu status` | Check if kugetsu is ready |
| `kugetsu delegate <msg>` | Send message to PM agent |
| `kugetsu doctor [--fix]` | Diagnose and fix issues |
| `kugetsu start <issue-ref> <msg>` | Start dev agent for issue |
| `kugetsu continue <issue-ref> <msg>` | Continue existing issue session |
| `kugetsu list` | List all tracked sessions |
| `kugetsu prune [--force]` | Clean up orphaned sessions |

## File Locations

| File | Location | Purpose |
|------|----------|---------|
| Chat Agent SOUL | `~/.hermes/SOUL-chat.md` | Personality |
| kugetsu-chat skill | `~/.hermes/skills/kugetsu-chat/` | Routing behavior |
| kugetsu | `~/.local/bin/kugetsu` | Main CLI |

~/.kugetsu/
├── sessions/
│   ├── base.json             # Base opencode session
│   └── pm-agent.json         # PM Agent opencode session
├── index.json                # Session registry
└── pm-agent.md               # PM context (optional, injected at init)

## Architecture Summary

```
~/.hermes/
├── SOUL-chat.md              # Chat Agent personality
└── skills/
    └── kugetsu-chat/        # Routing + delegation via kugetsu CLI

~/.kugetsu/
├── sessions/
│   ├── base.json             # Base opencode session
│   └── pm-agent.json         # PM Agent opencode session
├── index.json                # Session registry
└── pm-agent.md               # PM context (optional)

~/.local/bin/
└── kugetsu                  # Main CLI (handles delegation, status, doctor)
```

## PM Context (Optional)

To customize PM Agent behavior, create `~/.kugetsu/pm-agent.md` with additional context. This file is injected into the PM Agent session at init time.

## Security Notes

- Never commit `~/.kugetsu/` or SOUL files to version control
- Bot tokens should be in environment variables, not files
- PM agent session IDs are internal - don't expose to users
