LessCode is an AI-assisted code review tool for developers and coding agents working with JavaScript and TypeScript. It reviews committed changes, identifies issues such as unnecessary abstractions, duplicate helpers, and scope creep, then returns cited feedback and an optional checked patch—without modifying the supplied checkout. Meta’s models provide contextual reasoning, while deterministic code checks proposed edits and supported factual claims. Verified statements include their inputs and assumptions; other advice remains explicitly unverified. LessCode works through a CLI, MCP server, portable agent skill, or private GitHub review worker. Built using Meta’s Model API through Paperclip with Muse Wonder and Muse Spark, it also integrates Muse Spark Open through Baseten. The project is available on GitHub under Apache-2.0.
