Getting Started

This bot is designed to help teams manage GPU-related work in their repositories. Simply install the GitHub App, and the bot will automatically identify and tag GPU/CUDA/NVIDIA content in pull requests and issues.

No configuration needed beyond basic setup. The bot uses GitHub App authentication for secure API access and verifies all incoming webhooks with HMAC-SHA256 signatures.

Features

• GPU / CUDA validation in PRs
• CI checks for compute pipelines
• Benchmark triggers before release
• Issue and PR automation
