Aider OpenRouter Configuration

Configure Aider to use Claude 3.5 Sonnet through OpenRouter with optimal settings for AI-powered development workflows.

Instructions

Follow these steps to set up Aider with OpenRouter integration:

1. **Create the configuration file**

- Copy the configuration to `.aider.conf.yml` in your project root

- This file configures Aider's model, API access, and workflow settings

2. **Set up OpenRouter API access**

- Obtain an OpenRouter API key from https://openrouter.ai/

- Set the key either:

- In the config file: `openrouter-api-key: sk-or-v1-your-api-key`

- As an environment variable: `export OPENROUTER_API_KEY=sk-or-v1-your-api-key`

- Environment variable is recommended for security

3. **Configure the model**

- Model is set to `openrouter/anthropic/claude-3.5-sonnet`

- This uses Claude 3.5 Sonnet through OpenRouter's unified API

- To change models, update the `model:` line with another OpenRouter model identifier

4. **Configure Git integration**

- `git: true` enables Git tracking for all changes

- `auto-commits: false` requires manual commit approval

- This gives you full control over what gets committed

- Review changes with `git diff` before committing

5. **Set editor format**

- `edit-format: diff` shows changes in diff format

- Makes it easy to review what Aider modified

- Alternative formats: `whole`, `udiff`

6. **Start using Aider**

- Run `aider` in your project directory

- Aider will automatically load settings from `.aider.conf.yml`

- Begin pair programming with Claude 3.5 Sonnet
