aica - AI Code Analyzer

Motivation

There are already excellent code review tools like pr-agent and cursor. However, pr-agent is based on GitHub, which limits its use, and cursor is not open source, so it cannot be fully customized or integrated into other tools.

So, I decided to create a new tool with the following characteristics.

• Customizable
• Open Source
• Platform Independent

Features

• AI Code Review
• Automatic knowledge retrieving
• Symbol based code search for retrieving knowledge
• Vector based document search for retrieving knowledge
• Generate summary of changes
• Generate commit message
• Prompt customization
• Slack notification
• Single binary executable by bun build --compile
• GitHub Actions integration. (See wiki page to setup actions.)

Setup

Build and install a binary:

# if you don't have bun installed, install it first.
# With macOS:
# brew install bun

bun install
bun run build
cp ./dist/aica path-to-your-bin-directory

Setup environment variables:

export OPENAI_API_KEY=your_api_key
export OPENAI_MODEL=gpt-4-turbo-2024-04-09 # optional
