What This Skill Does

This skill sets up an Aider configuration file (`.aider.conf.yaml`) with:

Instructions

When the user asks to configure Aider or set up their Aider config:

1. **Create or update `.aider.conf.yaml`** in the project root or user's home directory with the following configuration:

2. **Model Aliases Section**

- Set up aliases for Claude models:

- `lazer-sonnet` → Claude Sonnet 4.5 (most capable)

- `lazer-haiku` → Claude 3.5 Haiku (fast and efficient)

- Set up aliases for Gemini models:

- `lazer-gemini-flash` → Gemini 3 Flash Preview

- `lazer-gemini-weak` → Gemini 2.0 Flash

- Set up alias for Grok:

- `lazer-grok` → Grok Code Fast 1

- All aliases use the `openai/` prefix format for compatibility

3. **Caching Configuration**

- Enable `cache-prompts: true` to cache system prompts for faster responses

- Set `cache-keepalive-pings: 6` to maintain cache with periodic keepalive pings

4. **Display Preferences**

- Enable `dark-mode: true` for dark theme

- Enable `pretty: true` for formatted output

- Enable `stream: true` for streaming responses

5. **File Location**

- Default location: `~/.aider.conf.yaml` (user-level config)

- Alternative: `.aider.conf.yaml` in project root (project-specific config)

# Claude

- "lazer-gemini-flash:openai/gemini/gemini-3-flash-preview"

- "lazer-gemini-weak:openai/gemini/gemini-2.0-flash"

# Grok Code Fast

- "lazer-grok:openai/xai/grok-code-fast-1"

cache-prompts: true

cache-keepalive-pings: 6

dark-mode: true
