PR Impact

概要

PR Impact is a static analysis tool designed to enhance code review processes by proactively identifying potential issues within pull requests. It performs comprehensive analysis including detecting breaking API changes and their downstream consumers, mapping the blast radius of code changes through import dependencies, and pinpointing gaps in test coverage. The tool consolidates these insights into a weighted risk score, making it easy for developers to assess the stability and safety of a PR. It integrates seamlessly into CI/CD pipelines as a quality gate and can be exposed as an MCP server tool for AI assistant integration.
