RA.Aid

RA.Aid (ReAct Aid) is a powerful AI-driven command-line tool that integrates aider (https://aider.chat/) within a LangChain ReAct agent loop. This unique combination allows developers to leverage aider's code editing capabilities while benefiting from LangChain's agent-based task execution framework. The tool provides an intelligent assistant that can help with research, planning, and implementation of development tasks.

⚠️ IMPORTANT: USE AT YOUR OWN RISK ⚠️

• This tool can and will automatically execute shell commands and make code changes
• The --cowboy-mode flag can be enabled to skip shell command approval prompts
• No warranty is provided, either express or implied
• Always use in version-controlled repositories
• Review proposed changes in your git diff before committing

Key Features

• Multi-Step Task Planning: The agent breaks down complex tasks into discrete, manageable steps and executes them sequentially. This systematic approach ensures thorough implementation and reduces errors.

• Automated Command Execution: The agent can run shell commands automatically to accomplish tasks. While this makes it powerful, it also means you should carefully review its actions.

• Three-Stage Architecture:

  1. Research: Analyzes codebases and gathers context
  2. Planning: Breaks down tasks into specific, actionable steps
  3. Implementation: Executes each planned step sequentially

What sets RA.Aid apart is its ability to handle complex programming tasks that extend beyond single-shot code edits. By combining research, strategic planning, and implementation into a cohesive workflow, RA.Aid can:

• Break down and execute multi-step programming tasks
• Research and analyze complex codebases to answer architectural questions
• Plan and implement significant code changes across multiple files
• Provide detailed explanations of existing code structure and functionality
• Execute sophisticated refactoring operations with proper planning

Installation

RA.Aid can be installed directly using pip:

pip install ra-aid

Prerequisites

Before using RA.Aid, you'll need:

1. Python package aider installed and available in your PATH:

pip install aider-chat

2. API keys for the required AI services:

# Set up API keys based on your preferred provider:

# For Anthropic Claude models (recommended)
export ANTHROPIC_API_KEY=your_api_key_here

# For OpenAI models
export OPENAI_API_KEY=your_api_key_here

# For OpenRouter provider (optional)
export OPENROUTER_API_KEY=your_api_key_here

# For OpenAI-compatible providers (optional)
export OPENAI_API_BASE=your_api_base_url

Note: The programmer tool (aider) will automatically select its model based on your available API keys:

• If ANTHROPIC_API_KEY is set, it will use Claude models
• If only OPENAI_API_KEY is set, it will use OpenAI models
• You can set multiple API keys to enable different features

You can get your API keys from:

• Anthropic API key: https://console.anthropic.com/
• OpenAI API key: https://platform.openai.com/api-keys
• OpenRouter API key: https://openrouter.ai/keys

Usage

RA.Aid is designed to be simple yet powerful. Here's how to use it:

# Basic usage
ra-aid -m "Your task or query here"

# Research-only mode (no implementation)
ra-aid -m "Explain the authentication flow" --research-only

Command Line Options

• -m, --message: The task or query to be executed (required)
• --research-only: Only perform research without implementation
• --cowboy-mode: Skip interactive approval for shell commands
• --provider: Specify the model provider (See Model Configuration section)
• --model: Specify the model name (See Model Configuration section)
• --expert-provider: Specify the provider for the expert tool (defaults to OpenAI)
• --expert-model: Specify the model name for the expert tool (defaults to o1-preview for OpenAI)

Model Configuration

RA.Aid supports multiple AI providers and models. The default model is Anthropic's Claude 3 Sonnet (claude-3-5-sonnet-20241022).

The programmer tool (aider) automatically selects its model based on your available API keys. It will use Claude models if ANTHROPIC_API_KEY is set, or fall back to OpenAI models if only OPENAI_API_KEY is available.

Note: The expert tool can be configured to use different providers (OpenAI, Anthropic, OpenRouter) using the --expert-provider flag along with the corresponding EXPERT_*API_KEY environment variables. Each provider requires its own API key set through the appropriate environment variable.

Environment Variables

RA.Aid supports multiple providers through environment variables:

• ANTHROPIC_API_KEY: Required for the default Anthropic provider
• OPENAI_API_KEY: Required for OpenAI provider
• OPENROUTER_API_KEY: Required for OpenRouter provider
• OPENAI_API_BASE: Required for OpenAI-compatible providers along with OPENAI_API_KEY

Expert Tool Environment Variables:

• EXPERT_OPENAI_API_KEY: API key for expert tool using OpenAI provider
• EXPERT_ANTHROPIC_API_KEY: API key for expert tool using Anthropic provider
• EXPERT_OPENROUTER_API_KEY: API key for expert tool using OpenRouter provider
• EXPERT_OPENAI_API_BASE: Base URL for expert tool using OpenAI-compatible provider

You can set these permanently in your shell's configuration file (e.g., ~/.bashrc or ~/.zshrc):

# Default provider (Anthropic)
export ANTHROPIC_API_KEY=your_api_key_here

# For OpenAI features and expert tool
export OPENAI_API_KEY=your_api_key_here

# For OpenRouter provider
export OPENROUTER_API_KEY=your_api_key_here

# For OpenAI-compatible providers
export OPENAI_API_BASE=your_api_base_url

Note: The expert tool defaults to OpenAI's o1-preview model with the OpenAI provider, but this can be configured using the --expert-provider flag along with the corresponding EXPERT_*_KEY environment variables.

Examples

1. Using Anthropic (Default)

   # Uses default model (claude-3-5-sonnet-20241022)
   ra-aid -m "Your task"
   
   # Or explicitly specify:
   ra-aid -m "Your task" --provider anthropic --model claude-3-5-sonnet-20241022
   

2. Using OpenAI

   ra-aid -m "Your task" --provider openai --model gpt-4o
   

3. Using OpenRouter

   ra-aid -m "Your task" --provider openrouter --model mistralai/mistral-large-2411
   

4. Configuring Expert Provider

   The expert tool is used by the agent for complex logic and debugging tasks. It can be configured to use different providers (OpenAI, Anthropic, OpenRouter) using the --expert-provider flag along with the corresponding EXPERT_*API_KEY environment variables.

   # Use Anthropic for expert tool
   export EXPERT_ANTHROPIC_API_KEY=your_anthropic_api_key
   ra-aid -m "Your task" --expert-provider anthropic --expert-model claude-3-5-sonnet-20241022
   
   # Use OpenRouter for expert tool
   export OPENROUTER_API_KEY=your_openrouter_api_key
   ra-aid -m "Your task" --expert-provider openrouter --expert-model mistralai/mistral-large-2411
   
   # Use default OpenAI for expert tool
   export EXPERT_OPENAI_API_KEY=your_openai_api_key
   ra-aid -m "Your task" --expert-provider openai --expert-model o1-preview
   

Important Notes:

• Performance varies between models. The default Claude 3 Sonnet model currently provides the best and most reliable results.
• Model configuration is done via command line arguments: --provider and --model
• The --model argument is required for all providers except Anthropic (which defaults to claude-3-5-sonnet-20241022)

Example Tasks

1. Code Analysis:

   ra-aid -m "Explain how the authentication middleware works" --research-only
   

2. Complex Changes:

   ra-aid -m "Refactor the database connection code to use connection pooling" --cowboy-mode
   

3. Automated Updates:

   ra-aid -m "Update deprecated API calls across the entire codebase" --cowboy-mode
   

4. Code Research:

   ra-aid -m "Analyze the current error handling patterns" --research-only
   

5. Code Research:

   ra-aid -m "Explain how the authentication middleware works" --research-only
   

6. Refactoring:

   ra-aid -m "Refactor the database connection code to use connection pooling" --cowboy-mode
   

Shell Command Automation with Cowboy Mode 🏇

The --cowboy-mode flag enables automated shell command execution without confirmation prompts. This is useful for:

• CI/CD pipelines
• Automated testing environments
• Batch processing operations
• Scripted workflows

ra-aid -m "Update all deprecated API calls" --cowboy-mode

⚠️ Important Safety Notes:

• Cowboy mode skips confirmation prompts for shell commands
• Always use in version-controlled repositories
• Ensure you have a clean working tree before running
• Review changes in git diff before committing

Environment Variables

See the Model Configuration section for details on provider-specific environment variables.
