# Implementation Complete ✅

## Summary of Changes

Your CodeCompanion configuration has been successfully updated to support Ollama with Tailscale network access.

## What Was Changed

### 1. Modified File
**`lua/shelbybark/plugins/codecompanion.lua`**
- Added Ollama adapter (lines 30-45)
- Configured environment variable support
- Added Ollama keymaps `<leader>cll` (lines 223-237)

### 2. Created Documentation (7 files)
- `README_OLLAMA_INTEGRATION.md` - Main overview
- `docs/OLLAMA_SETUP.md` - Comprehensive setup guide
- `docs/OLLAMA_QUICK_SETUP.md` - Quick reference for other machines
- `docs/ARCHITECTURE.md` - Network architecture diagrams
- `docs/TROUBLESHOOTING.md` - Common issues and solutions
- `docs/IMPLEMENTATION_CHECKLIST.md` - Step-by-step checklist
- `docs/QUICK_REFERENCE.md` - Quick reference card
- `docs/ollama_env_example.sh` - Shell configuration example

## How It Works

### Local Access (Main Machine)
```bash
nvim
# Press <leader>cll
# Connects to http://localhost:11434 automatically
```

### Remote Access (Other Machines)
```bash
export OLLAMA_ENDPOINT="http://100.123.45.67:11434"
nvim
# Press <leader>cll
# Connects via Tailscale to your Ollama server
```

## Key Features

✅ **Environment-Based**: Reads `OLLAMA_ENDPOINT` environment variable
✅ **Fallback Support**: Defaults to localhost if env var not set
✅ **Easy Switching**: Use `<leader>cll` to chat with Ollama
✅ **Network-Aware**: Works locally and remotely
✅ **Secure**: All traffic encrypted via Tailscale
✅ **No Code Changes**: Just set an environment variable on other machines

## Configuration Details

### Ollama Adapter
- **Location**: `lua/shelbybark/plugins/codecompanion.lua` (lines 30-45)
- **Default Model**: `mistral` (7B, fast and capable)
- **Endpoint**: Reads from `OLLAMA_ENDPOINT` env var
- **Fallback**: `http://localhost:11434`

### Keymaps
- `<leader>cll` - Chat with Ollama (normal and visual modes)
- `<leader>cc` - Chat with Claude Haiku (existing)
- `<leader>cs` - Chat with Claude Sonnet (existing)
- `<leader>co` - Chat with Claude Opus (existing)

## Next Steps

### 1. On Your Ollama Server Machine

```bash
# Ensure Ollama listens on all interfaces
sudo systemctl edit ollama
# Add: Environment="OLLAMA_HOST=0.0.0.0:11434"
# Save and exit
sudo systemctl restart ollama

# Pull a model
ollama pull mistral

# Find your Tailscale IP
tailscale ip -4
# Note this down (e.g., 100.123.45.67)

# Test it works
curl http://localhost:11434/api/tags
```

### 2. On Other Machines

```bash
# Add to ~/.zshrc, ~/.bashrc, or ~/.config/fish/config.fish
export OLLAMA_ENDPOINT="http://100.123.45.67:11434"

# Reload shell
source ~/.zshrc  # or ~/.bashrc

# Test connection
curl $OLLAMA_ENDPOINT/api/tags

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

### 3. Test in Neovim

```vim
" Press <leader>cll to open Ollama chat
" Type a message and press Enter
" You should get a response from Ollama
```
