Aider Gemini Configuration

Configure Aider to use Google Gemini 2.5 Pro models with automatic conventions reading and continuous integration testing.

What This Does

This skill configures Aider (an AI pair programming tool) to:

Instructions

When setting up Aider configuration for a project using Google Gemini models:

1. **Create `.aider.conf.yml` in the project root** with the following structure:

2. **Set the primary model** to `gemini/gemini-2.5-pro` for high-quality code generation and editing

3. **Configure the editor model** to use the same `gemini/gemini-2.5-pro` for consistency in editing tasks

4. **Set the weak model** to `gemini/gemini-2.5-flash` for faster, lightweight operations like file searching or simple queries

5. **Add auto-read files** under the `read:` section to automatically include important context files like:

- `CONVENTIONS.md` - Project coding conventions and standards

- `CLAUDE.md` - Project context and instructions

- Other relevant documentation files

6. **Configure test command** using `test-cmd:` to run after each edit:

- For wiki projects: `./ci-loop.sh` to rebuild documentation

- For code projects: test suite commands like `npm test` or `pytest`

- Leave empty if no auto-testing is needed

7. **Set edit format** to `whole` for cleaner whole-file replacements, or use `diff` for incremental changes

Example Configuration

```yaml

Primary model for main coding tasks

model: gemini/gemini-2.5-pro

Editor model for code editing

editor-model: gemini/gemini-2.5-pro

Lightweight model for quick operations

weak-model: gemini/gemini-2.5-flash

Auto-read project conventions

read:

- CONVENTIONS.md

Run CI loop after edits (optional)

test-cmd: "./ci-loop.sh"

Use whole-file editing

edit-format: whole

```
