Thalia

Thalia is a dedicated macOS application designed for agentic coding using Meta's Muse Code CLI. It offers a robust framework for developers to plan, steer, review, and ship code with precision. Key features include: • Plan mode for read-only preview of proposed changes • Step-by-step command review before execution • Snapshot approval and invalidation upon subsequent edits • Built-in checkpoints, MCP connectors, voice mode, and embedded terminal Thalia empowers developers with full control over the coding process. The unique Plan mode ensures transparency by displaying every command and its impact before any changes are committed. Users can review proposed modifications, run their own checks, and approve exact snapshots, ensuring code integrity. Any later edit automatically invalidates the approved snapshot, maintaining a clear audit trail. Built natively for Apple Silicon Macs running macOS 27, Thalia ensures optimal performance and a seamless user experience. It uses your existing Muse access and prioritizes user privacy by sending no telemetry data. The integration of checkpoints and MCP connectors further enhances project management capabilities, while voice mode and an embedded terminal provide versatile interaction methods. This tool is ideal for developers and engineering teams seeking a powerful, transparent, and native macOS client for managing code projects with Muse. It streamlines the development workflow from initial request to pull request, ensuring clarity and control at every stage.
