LeslieWylie/dsh-task-relay

dsh-task-relay is a purpose-built plugin for DeepSeek Harness (DSH) that adds persistent cross-session and multi-agent task handoff capabilities to DSH. DSH’s default design treats each session as an independent unit of work, with no built-in way to share task context between different sessions or sub-agents, and this plugin fills that gap. To install the plugin, users can run a simple DSH CLI command targeting the GitHub repository, or manually add an entry for the plugin to their cordis.yml configuration file. The plugin registers 7 different tools to interact with the shared task queue and handoff summary system.

This plugin is designed for DSH users who need to split large development tasks across multiple sessions or delegate work to sub-agents. A common cross-session workflow starts with the user pushing a new task with a title, priority, and tags to the shared queue from their current session. When they open a new session later, they can query the queue for open, high-priority tasks, claim the task they want to work on, and mark it as done once they finish the work with a result summary. They can also write handoff summaries at the end of a session and read them when starting a new session to stay updated on prior progress.

The plugin is released under the open-source MIT license, and all task and handoff data is stored locally on the user’s machine, by default at $HOME/.dsh/task-relay/queue.json. It uses atomic write operations to prevent data corruption, and supports custom storage paths via plugin configuration. The plugin runs entirely locally, does not make any external network calls, and does not execute external commands. It includes input validation for all user-provided data, enforces session ownership checks for task operations, and sets directory permissions to 700 to keep user data secure.
