Aider Claude Haiku Configuration

This skill configures Aider to use Claude Haiku 4.5 through OpenRouter for AI-assisted coding sessions with optimized settings for performance and git workflow.

Configuration Overview

Sets up Aider with Claude Haiku 4.5 across all model tiers (main, editor, and weak models) for consistent behavior. Optimizes map tokens for better context management and configures git integration with proper attribution.

Key Settings

**Model Configuration:**

**Performance Tuning:**

**Git Integration:**

**UX Preferences:**

**Context Management:**

Usage

Create an `.aider.conf.yml` file in your project root with this configuration:

```yaml

model: openrouter/anthropic/claude-haiku-4.5

editor-model: openrouter/anthropic/claude-haiku-4.5

weak-model: openrouter/anthropic/claude-haiku-4.5

map-tokens: 2048

auto-commits: false

dirty-commits: false

attribute-author: true

attribute-committer: true

git: true

gitignore: false

dark-mode: true

pretty: true

stream: true

read: AGENTS_SUMMARY.md

chat-language: english

commit-language: english

cache-prompts: true

cache-keepalive-pings: 3

notifications: false

```

Ensure you have:

1. OpenRouter API key configured in your environment

2. `AGENTS_SUMMARY.md` file in your project root (or remove the `read` line)

3. Git repository initialized

Then run `aider` in your project directory. The configuration will be automatically loaded.

Customization

**To use different models:** Replace `openrouter/anthropic/claude-haiku-4.5` with your preferred model identifier

**To adjust context window:** Modify `map-tokens` value based on your codebase size (higher = more context, higher cost)

**To enable auto-commits:** Set `auto-commits: true` if you prefer automatic git commits after each change

**To add more context files:** Extend the `read` line with comma-separated file paths

Notes

This configuration prioritizes manual control over automation, making it ideal for developers who want to review changes before committing. The Claude Haiku model provides a good balance of speed and capability for most coding tasks.
