dsh-session-nexus：DSH 会话生命周期与跨会话消息插件
dsh-session-nexus 是一款由 qiushi-dev 维护的 MIT 许可非官方 DSH 社区插件，旨在将 DeepSeek Harness 会话转化为可操作对象。它主要提供两大核心能力：一是会话生命周期控制，支持通过斜杠命令显式挂载冷会话、取消归档及在开启特定配置后删除会话；二是跨会话消息交互，允许开发者或模型向其他会话投递唤醒或静默消息，并获取目标会话的标题、时间线及摘要。插件支持多种地址格式，具备发送者归属、防自投递及循环限制等安全机制，并在 Web UI 中增强会话 ID 展示。安装简单，通过 `dsh plugin` 命令即可添加，默认启用消息投递工具但关闭删除功能。该

dsh-agent-messaging is an MIT-licensed plugin for DeepSeek Harness, designed to address the lack of a direct communication channel between multi-agent sessions, resource conflicts, and duplicate decision-making. By providing cross-session message passing, claim checking, and a decision ledger, this plugin reduces redundant work, contradictions, and deadlocks across sessions. Core features include: using `peer_send` to send short text messages to designated sessions in steer (interrupt), followup (new turn), or context (non-wake) modes; publishing capability cards via `peer_card` to declare session aliases, roles, owned resources, and groupings; and automatically detecting resource claim conflicts while indicating the holder.

Anthropic launched cross-session messaging in Claude Code v2.1.224 (released on August 7, 2026): independently running sessions on macOS/Linux can discover each other via ListAgents and send each other plain text summaries via SendMessage, without manually copying context between terminals. The messages do not carry conversation history or files, and the recipient still needs to approve sensitive operations on their own; the communication uses local sockets on the same machine, and cross-machine support is limited to replies via Remote Control. This article introduces the mechanism, scenarios, usage and security boundaries based on official documentation.
