GitHub user duo121 introduces TermHub, an open-source terminal control gateway enabling AI agents to programmatically manage iTerm2 and Windows Terminal sessions. This tool allows AI systems to open tabs, execute commands, and capture output in real time, streamlining terminal automation workflows.

The SDK supports cross-platform functionality: macOS integrates with iTerm2 and macOS Terminal, while Windows accommodates Windows Terminal and CMD. Developers can use keypress simulation, session resolution, and output capture features to automate repetitive tasks. A new session checkpoint system ensures AI agents only process output generated after specific commands, reducing redundancy in automated workflows.

TermHub’s command-line interface includes tools like `thub list` for session management and `thub send` for input execution. The SDK example demonstrates opening an iTerm2 tab, sending `echo hello from sdk`, and capturing output. Windows Terminal users benefit from keyboard automation, though mouse click support remains limited to macOS.

By storing session states locally in `~/.termhub/state`, TermHub enables parallel AI operations without conflicts. This advancement addresses a critical gap in terminal automation, offering developers a robust framework for AI-driven DevOps tasks.
