dsh-agent-messaging

DeepSeek Harness lets you spin up multiple agent sessions, but out of the box, these sessions are isolated—they can't communicate, which often leads to repeated work, conflicting actions, and silent deadlocks. The dsh-agent-messaging plugin addresses this by adding a messaging infrastructure that enables cross-session verification, claims, and a decision ledger, so agents can inform, coordinate, and avoid stepping on each other's toes.

At its heart, the plugin offers tools like peer_list to discover other sessions, peer_send to deliver messages with strategic timing, peer_claim to announce work in progress, and peer_verify to validate claims with peers before acting. This setup targets key failure modes in multi-agent systems, such as step repetition and task derailment, by ensuring that only meaningful messages are sent and that interactions are logged for transparency.

This plugin is perfect for developers working with DeepSeek Harness in multi-session scenarios—whether managing parallel code changes, coordinating across different directories, or simply wanting to prevent agent conflicts. If you need your independent sessions to work together without duplicating efforts or getting stuck in deadlocks, dsh-agent-messaging provides the essential communication layer to make that happen.
