# CodeCompanion + Ollama Integration Summary

## What Was Done

Your CodeCompanion configuration has been updated to support Ollama models alongside your existing Claude adapters. Here's what changed:

### 1. **Added Ollama Adapter** (`lua/shelbybark/plugins/codecompanion.lua`)
   - Reads `OLLAMA_ENDPOINT` environment variable
   - Defaults to `http://localhost:11434` if not set
   - Uses `mistral` as the default model (configurable)

### 2. **Added Ollama Keymaps**
   - `<leader>cll` - Toggle Ollama chat (normal and visual modes)
   - Works alongside existing Claude keymaps

### 3. **Created Documentation**
   - `docs/OLLAMA_SETUP.md` - Comprehensive setup guide
   - `docs/OLLAMA_QUICK_SETUP.md` - Quick reference for other machines
   - `docs/ollama_env_example.sh` - Shell configuration example

## How It Works

### On Your Main Machine (with Ollama)
```bash
# Ollama runs locally, CodeCompanion uses http://localhost:11434 by default
nvim
# Press <leader>cll to chat with Ollama
```

### On Other Machines (without Ollama)
```bash
# Set environment variable to your Ollama server's Tailscale IP
export OLLAMA_ENDPOINT="http://100.123.45.67:11434"
nvim
# Press <leader>cll to chat with Ollama via Tailscale
```

## Key Features

✅ **Network Access**: Access Ollama from any machine on your Tailscale network
✅ **Fallback Support**: Keep Claude as primary, use Ollama as alternative
✅ **Easy Switching**: Use keymaps to switch between models instantly
✅ **Environment-Based**: Configuration adapts to each machine automatically
✅ **No Code Changes**: Just set an environment variable on other machines

## Next Steps

### 1. **On Your Ollama Server Machine**

Ensure Ollama is exposed to the network:
```bash
# Check current Ollama binding
ps aux | grep ollama

# If needed, set it to listen on all interfaces
sudo systemctl edit ollama
# Add: Environment="OLLAMA_HOST=0.0.0.0:11434"
# Save and exit, then:
sudo systemctl restart ollama

# Find your Tailscale IP
tailscale ip -4
```

### 2. **On Other Machines**

Add to your shell config (`~/.zshrc`, `~/.bashrc`, etc.):
```bash
export OLLAMA_ENDPOINT="http://YOUR_TAILSCALE_IP:11434"
```

### 3. **Test It**

```bash
# Verify connection
curl http://YOUR_TAILSCALE_IP:11434/api/tags

# Start Neovim and press <leader>cll
nvim
```

## Configuration Details

### Ollama Adapter Settings
- **Location**: `lua/shelbybark/plugins/codecompanion.lua` (lines 35-45)
- **Default Model**: `mistral` (change to your preference)
- **Endpoint**: Read from `OLLAMA_ENDPOINT` env var
- **Fallback**: `http://localhost:11434`

### Available Models to Try
- `mistral` - Fast, good quality (recommended)
- `neural-chat` - Optimized for conversation
- `dolphin-mixtral` - Larger, higher quality
- `llama2` - General purpose
- `orca-mini` - Very fast, lightweight

Pull models with: `ollama pull <model-name>`

## Troubleshooting

### Connection Issues
```bash
# Test Ollama is running
curl http://localhost:11434/api/tags

# Test Tailscale connectivity
ping 100.x.x.x  # Use your Tailscale IP

# Check Ollama is bound to network
sudo netstat -tlnp | grep 11434
```

### Model Issues
```bash
# List available models
curl http://localhost:11434/api/tags | jq '.models[].name'

# Pull a model
ollama pull mistral
```
