Task Passport: Relaying Between Harnesses with Task Passports, Without Moving Chat History

Task Passport is an open task handoff protocol and DSH thin plugin maintained by dongsheng123132. The passport stores versioned task states in the store; TaskPack is a single-file module designed for cross-user and cross-machine portability. It supports CLI and MCP interfaces including list, open, checkpoint, pack, land, and conformance, and can connect to U-King, local directories, or custom Providers. The same state can be read and written by DSH, Claude Code, Codex, and WorkBuddy. It does not replicate chat history, and checkpoints include version conflict detection.
