Moon is a monorepo build system and task runner designed to orchestrate complex projects with multiple packages. It functions as a dependency graph orchestrator that executes build targets in topological order and utilizes input hashing to cache results and skip redundant work.
The project features a polyglot toolchain manager that automates the installation and versioning of language runtimes and CLI tools to ensure environment consistency. It also includes a plugin framework based on WebAssembly, allowing developers to extend build logic and toolchain behavior using any supported language.
The system covers a broad range of capabilities, including incremental build execution, CI pipeline optimization via task sharding and affected-target filtering, and the generation of optimized multi-stage Dockerfiles. It further provides tools for repository governance through code ownership management and the automation of version control hooks.
The tool provides interface servers that enable AI agents to query project state, trigger build tasks, and manage toolchain configurations.
