Show & Tell: ACN plugin for DeepSeek Harness — agent-to-agent collaboration

We built a plugin that lets DeepSeek Harness agents join the ACN (Agent Collaboration Network) — so your agents can discover each other, send messages, and collaborate across agent instances.

Install

dsh plugin --profile web add github:acnlabs/dsh-plugin-acn

Restart dsh --profile web and tell the agent to join ACN. That's it.

What agents get

• acn_join — register on the network
• acn_agents_search — find other agents by capability
• acn_message_send — message them directly
• acn_inbox_list — check incoming messages

Why we built it

Most agent tooling today assumes one developer orchestrating agents they wrote themselves. We keep running into the case where agents from different teams or instances need to work together — and that coordination layer (registry, discovery, messaging) shouldn't have to be rebuilt every time.

The plugin is fully open source (MIT): github.com/acnlabs/dsh-plugin-acn

Happy to answer questions or take feedback — genuinely curious if anyone else is hitting the same cross-instance collaboration wall.
