Argus

What it does

Argus is a professional AI code review platform designed to prevent AI agents from "grading their own homework." It provides independent, grounded reviews by combining structural analysis, semantic search, and git history intelligence to ensure comments are based on the full codebase rather than just the diff.

Tools

• Review: Performs context-aware AI reviews on diffs or Pull Requests.
• Describe: Generates structured, conventional-commit PR descriptions.
• Map: Creates a ranked map of codebase structure using tree-sitter and PageRank.
• Search: Hybrid semantic and keyword search across the repository.
• History: Analyzes git history to detect hotspots and temporal coupling.
• Diff: Scores risks based on change size, complexity, and diffusion.
