dsh-agent-relay

In today's AI development landscape, many agent frameworks (such as Codex and Claude Code) focus on single-agent reasoning and tool usage, yet they lack standardized communication mechanisms between agents. When multiple independent agents run concurrently on the same machine, they cannot directly engage in code reviews, fact-checking, or collaborative task distribution, creating a bottleneck for teamwork. dsh-agent-relay addresses this architectural gap by providing a fully decoupled, lightweight local communication relay bus, enabling developers to easily build collaborative links for agent fleets.

The plugin's core strengths lie in its secure and reliable design: it defaults to binding to the local loopback address (Loopback-First), eliminating cloud dependencies, while ensuring rigorous authentication through HMAC-SHA256 signature verification. The message routing employs high-reliability delivery with features like a 7-day TTL queue, exponential backoff retries, and idempotent deduplication, safeguarding data integrity and privacy. For DeepSeek Harness users, it offers first-class plugin integration, registering multiple model tools and providing a graphical status panel for seamless and intuitive inter-agent collaboration.

dsh-agent-relay is ideal for developers and researchers running multiple AI agents in local environments, especially teams using DeepSeek Harness or similar tools to build agent fleets. If you need to securely exchange messages, share tasks, or validate results among different agents (like dsh, Codex, or Python clients) without introducing complex external services or compromising data privacy, this plugin serves as an excellent lightweight solution. It allows you to focus on collaborative innovation with agents rather than the intricacies of underlying communication setup.
