# Manage Large AI Code Changes with Vestige Easily review and manage code changes generated by AI. - **Source:** [Hacker News: Show HN](https://news.ycombinator.com) - **Published:** 2026-07-20 - **Topic:** [Software & Engineering](https://brifing.si/c/engineering) - **Original article:** - **On Brifing:** https://brifing.si/s/22e2b0cc-a19a-44a8-986f-aaa6fd90e255 ## Understanding AI Code Changes Vestige is a tool designed to manage large-scale code changes generated by AI. It allows developers to quickly understand the impact of changes and push them with confidence. It's an ideal solution for extensive changes made by LLMs. ## Where to Start? Vestige provides a guide showing where changes begin and how they progress. Developers can easily see the scope of changes and potential risks. This enables quick and effective reviews even in complex codebases. ## Impact Analysis The tool calculates the 'blast radius' of changes, showing which code parts might be affected. This analysis runs locally and is deterministic, not relying on LLM guesses. Thus, it delivers more reliable results. ## Preserving Code Context Vestige provides context for what the code did before changes. Developers can better evaluate changes without having to re-derive this information. This feature saves time, especially in large projects. ## Privacy and Security Vestige runs code analyses 100% locally. Your code structure is never sent externally. Only snippets for explicit features (e.g., code explanations) are sent. No telemetry or analytics data is collected, ensuring your privacy. ## Future and Limitations Currently supports TypeScript, Python, Go, and Java. Rescan time may increase for large monorepos. As a first release, it has some limitations, but offers reliable impact analysis via static call graphs. ## Sources covering this story - https://marketplace.visualstudio.com/items?itemName=Vestige.vestige-vscode-extension — --- _Summary written by Brifing from the original reporting.
