Aider Configuration for Google Gemini

Configure Aider AI coding assistant to use Google Gemini models with settings optimized for delivery management tools and CI/CD workflows.

What This Skill Does

This skill sets up an `.aider.conf.yml` configuration file that configures Aider to work with Google Gemini models (specifically Gemini 2.5 Flash Preview). The configuration is optimized for:

Instructions

When the user requests Aider configuration for Gemini or asks to set up Aider for CI/CD:

1. **Read existing configuration** (if any):

- Check if `.aider.conf.yml` exists in the project root

- Read the current configuration to preserve any custom settings

2. **Create the configuration file** at `.aider.conf.yml` with the following settings:

```yaml

Aider configuration optimized for Google Gemini models

model: gemini/gemini-2.5-flash-preview-05-20 # Default Gemini model

edit-format: whole # Uses more tokens but gives better results

max-chat-history-tokens: 1000000 # Gemini 1.5 Pro has 1M+ context window

cache-prompts: true

stream: false # Disable streaming for GitHub Actions

pretty: false # Disable pretty output for CI logs

Additional settings for better responses

show-diffs: true

auto-commits: false # Disable auto commits in CI

yes-always: true # Auto-accept all suggestions

```

3. **Explain the configuration**:

- **model**: Uses Gemini 2.5 Flash Preview (fast and cost-effective)

- **edit-format**: `whole` provides better results by editing entire files

- **max-chat-history-tokens**: Leverages Gemini's large 1M+ token context window

- **cache-prompts**: Enables prompt caching for faster responses

- **stream**: Disabled for cleaner CI/CD logs

- **pretty**: Disabled for machine-readable output in automated environments

- **show-diffs**: Shows code changes for review

- **auto-commits**: Disabled to prevent automatic commits in CI

- **yes-always**: Auto-accepts suggestions for non-interactive environments

4. **Additional recommendations**:

- Inform the user they need a Gemini API key set as `GEMINI_API_KEY` environment variable

- For interactive development, they may want to set `stream: true` and `pretty: true` in a separate local config

- Suggest creating `.aider.conf.yml.local` for developer-specific overrides (add to `.gitignore`)

Usage Examples

**Basic setup:**

> "Set up Aider configuration for Gemini"

**CI/CD setup:**

> "Configure Aider for GitHub Actions with Gemini"

**Custom model:**

> "Set up Aider with Gemini Pro instead of Flash"
