Vestige

Vestige is a Visual Studio Code extension aimed at engineers who accept a lot of AI-generated code and need to review it responsibly before it lands on main. Instead of dumping a long unified diff, Vestige reorganizes an AI change into review cards backed by two structural views: a call graph showing what functions the touched code calls into (and is called from), and a file dependency map showing the blast radius across the workspace. The idea is to answer the three questions a reviewer actually has — where do I start reading, what could this break, and what did the surrounding code look like before the model rewrote it — without forcing you to re-derive that context by hand.

The AI role is deliberately narrow. Impact analysis, call graphs and dependency edges are computed locally using tree-sitter WebAssembly parsers, so the structural claims about a diff are deterministic rather than hallucinated. The LLM is only invoked to label nodes and write natural-language summaries of what a change is doing, and only selected snippets — not your whole repo — are sent to the Vestige backend (AWS/OpenAI) for those calls. There is no telemetry.

Supported languages at v0.1.0 are TypeScript/JavaScript, Python, Go and Java, and the extension currently requires a single-root workspace. It is a first public release from an independent publisher, so expect rough edges around incremental parsing and dynamic dispatch, but the core workflow — 'my agent wrote 900 lines, show me the review order and what it touches' — is already usable and slots neatly next to Copilot, Cursor, Claude Code and similar AI coding assistants.
