AI-powered Pull Request Description Generator

AIPR - Agentic Pull Request Description Generator

Automatically analyze git diffs and vulnerabilities to generate comprehensive, well-structured pull request descriptions. By intelligently detecting changes, performing security scans, and leveraging state-of-the-art AI models, AIPR helps teams save time while maintaining high-quality, consistent pull request descriptions.

AI-Driven Development

This project follows an AI-driven development workflow:

• 🤖 Built with AI - Developed using Claude Code with comprehensive AI guidance
• 📋 AI Task Assignment - Structured workflow for AI agents documented in CONTRIBUTING.md
• 📚 AI-Friendly Documentation - Comprehensive guides for AI agents in CLAUDE.md and Architecture Decision Records
• 🏗️ Architecture-First Design - ADRs define behavior and guide implementation patterns

# Install with pipx (recommended)
pipx install pr-generator-agent

# Or with pip
pip install pr-generator-agent

# Set the environment variable for the API key
export ANTHROPIC_API_KEY="your-api-key"

# Generate a PR description
aipr

# Generate a conventional commit message
aipr commit

# Custom usage - Analyze changes against main branch
# Include: Vulnerability scanning
# Use: Azure OpenAI o1-mini model
# Prompt: meta template
# Output: Verbose
aipr pr -t main --vulns -p meta -m azure/o1-mini -v

# Inline with merge request creation
gh pr create -b "$(aipr pr -s)" -t "feat: New Feature"

# Inline with commit creation
git commit -m "$(aipr commit)"

Key Features

• 🔍 Smart Detection: Automatically analyzes working tree changes or compares branches
• 📝 Conventional Commits: Generate conventional commit messages from staged changes
• 🛡️ Security First: Optional vulnerability scanning between branches using Trivy
• 🤖 AI-Powered: Multiple AI providers (Azure OpenAI, OpenAI, Anthropic, Gemini) for optimal results

Commit Message Generation

$ git add src/auth.py tests/test_auth.py
$ aipr commit
feat(auth): add OAuth2 authentication support

$ git add requirements.txt
$ aipr commit
build(deps): update dependencies to latest versions

$ git add README.md docs/guide.md
$ aipr commit
docs: update installation and usage documentation

Requirements

• Python 3.11 or higher (3.11, 3.12 officially supported)
• Git
• LLM API Key (Anthropic, OpenAI, or Azure OpenAI)
• Trivy (used for --vulns scanning)

Environment Variables

Anthropic (Default)

• ANTHROPIC_API_KEY: Anthropic API key

Azure OpenAI

• AZURE_API_KEY: Azure OpenAI API key
• AZURE_API_BASE: Azure endpoint URL
• AZURE_API_VERSION: API version (default: "2024-02-15-preview")

OpenAI

• OPENAI_API_KEY: OpenAI API key

Google Gemini

• GEMINI_API_KEY: Google Gemini API key

Usage

AIPR provides two main commands:

PR Command (Pull Request Descriptions)

aipr pr [options]  # or just 'aipr' for backward compatibility

Options:

• -t, --target: Compare changes with specific branch (default: auto-detects main/master)
• -p, --prompt: Select prompt template (e.g., 'meta')
• --vulns: Include vulnerability scanning
• --working-tree: Use working tree changes

Global Options:

• -v, --verbose: Show API interaction details
• -d, --debug: Preview prompts without API calls
• -s, --silent: Output only the description
• -m, --model: Specify AI model to use

The tool intelligently detects changes by:

1. Using staged/unstaged changes if present
2. Comparing against target branch if working tree is clean

Commit Command (Conventional Commit Messages)

aipr commit [options]

Options:

• --conventional: Generate conventional commit message (default)
• --format: Message format (currently only 'conventional')
• --context: Additional context for the commit message

Examples:

# Basic commit message generation
git add .
aipr commit

# With additional context
aipr commit --context "upstream sync"

# Use in automation
git commit -m "$(aipr commit)"
