Meta Muse Code: Setup, Pricing, & First Look

Meta has announced Muse Code, a new terminal-native coding agent. This agent aims to help developers interact with AI directly within their code repositories. To get started, you download an install script from Meta's developer portal. It's important to inspect this script and verify its checksum before running it. After installation, you authenticate and choose between a Standard or Contributor pricing tier. You then initialize Muse Code in your Git repository and set up a `.museignore` file to exclude sensitive data. A `MUSE_CODE.md` file is also created to define project conventions and testing expectations. Finally, you can test tasks in a worktree and review the agent's proposed changes. This tool enters a market with other AI coding agents like Claude Code and Gemini CLI. Understanding its setup and configuration is key to using it effectively in a production codebase.
