Meta Platforms has released a public preview of Muse Code, a terminal-based AI coding agent designed to help developers plan code changes, execute programming tasks and validate results across software projects. Muse Code gives developers a terminal-based workflow for AI coding tasksMuse Code is built for developers who work from the command line rather than a browser-only interface. In that setting, Muse Code can function as a practical assistant for code review preparation, bug investigation, documentation cleanup and structured implementation planning. Use Muse Code first on documentation, tests, refactoring proposals or isolated utility code before allowing it near production systems, deployment scripts or customer-facing functionality. Until those signals are stronger, Muse Code is best treated as a promising development assistant, not an autonomous engineer.
