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)

# Ollama runs locally, CodeCompanion uses http://localhost:11434 by default
nvim
# Press <leader>cll to chat with Ollama

On Other Machines (without Ollama)

# 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:

# 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.):

export OLLAMA_ENDPOINT="http://YOUR_TAILSCALE_IP:11434"

3. Test It

# 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

# 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

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

# Pull a model
ollama pull mistral
