Shepherd Terminal is a persistent macOS workspace designed to streamline the management of coding agents, such as Codex and Claude. It enables users to run these agents across multiple tabs, panes, and even remote machines, providing a unified environment for complex development tasks. The primary purpose is to offer a robust and organized platform for developers who leverage AI coding assistants, ensuring that their work remains active and accessible.
The challenge Shepherd Terminal addresses is the inherent difficulty in managing multiple AI coding agents simultaneously. Developers often find themselves juggling numerous terminal windows, losing track of which agent is active, waiting for input, or has completed its task. This fragmentation leads to lost context, decreased productivity, and a cumbersome workflow. Shepherd aims to consolidate these disparate sessions into a cohesive and manageable experience.
One of Shepherd's key features is its persistence. Terminal sessions remain alive even after the application is closed, preventing the loss of work due to accidental closures or system restarts. This ensures that agents continue their tasks uninterrupted and users can resume their work exactly where they left off. The system actively tracks the status of each agent, clearly indicating whether they are working, waiting for input, or have finished their operations, providing real-time visibility into the ongoing processes.
Shepherd enhances agent capabilities by allowing them to understand and control the current workspace. Agents can interact with tabs and panes, enabling more dynamic and integrated workflows. Furthermore, Shepherd facilitates feedback loops by allowing agents to collect feedback through browser reviews. This feature enables users to provide structured feedback directly from their browser, which the agent can then process, creating a more iterative and responsive development cycle.
Users can return to previous agent sessions and inspect their files, view code differences (diffs), and review Git history. This contextual awareness is crucial for understanding the evolution of code and the impact of agent actions. Shepherd also supports connecting to remote development machines over SSH, extending its capabilities to distributed environments. This allows users to access terminals, files, and local services on remote machines as if they were local.
Shepherd Terminal operates by creating a persistent, unified workspace for coding agents. It installs a lightweight Rust service with a session keeper on remote machines, ensuring that agent processes continue even if the SSH connection drops or the main application is closed. This robust session management allows for long-running reliability, a core tenet of the product's design. The system presents sibling pane content as structured tool output, including source and pane context, to help agents distinguish between data and instructions, thereby reducing misinterpretation.
The benefits for users include significantly improved management of multiple coding agents, reduced context loss, and a more organized development workflow. By keeping sessions alive and providing real-time status monitoring, Shepherd allows developers to focus on coding rather than managing their tools. The ability to resume previous sessions and inspect historical changes further enhances productivity and code quality.
Concrete use cases for Shepherd Terminal include managing parallel agent tasks for code generation, debugging across different modules, refactoring large codebases with multiple agents, and conducting code reviews where agents assist in identifying issues and suggesting fixes. Developers can also use it for continuous integration tasks or long-running data processing jobs managed by AI agents.
Shepherd Terminal is currently available as a macOS application for Apple silicon Macs running macOS 14 or later. The product is offered for free. An iOS companion app is also in development for monitoring agents and providing feedback remotely. The product integrates with AI models like Codex and Claude, and the underlying technology includes a Rust service for session management.
In summary, Shepherd Terminal provides a persistent and integrated environment for managing coding agents, transforming the way developers interact with AI assistants by ensuring continuity, visibility, and control across their development workflow.
