pr-filler

A tool that automatically fills out GitHub pull request descriptions using AI by analyzing code diffs.

✨ Demo

Installation

sudo npm install -g pr-filler

Prerequisites

Set the following environment variables:

export GITHUB_ACCESS_TOKEN="your_github_token"
export OPENAI_API_KEY="your_openai_api_key"

Usage

# Interactive mode
pr-filler

# With PR URL as argument
pr-filler https://github.com/owner/repo/pull/123

# With AI model specification
pr-filler --url https://github.com/owner/repo/pull/123 --model gpt-4o

# Using short flags
pr-filler -u https://github.com/owner/repo/pull/123 -m gpt-3.5-turbo

Command-line flags

• --url, -u: Specify the GitHub pull request URL
• --model, -m: Specify the OpenAI model to use (default: gpt-4.1)

How it works

1. Fetches the existing PR template and code diff from GitHub
2. Sends both to the specified OpenAI model (default: gpt-4.1) to generate a detailed description
3. Updates the PR body on GitHub with the AI-generated content
