DeepSeek Harness Cross-Session Call Center: dsh-agents-in-the-loop

`dsh-agents-in-the-loop` is a cross-session communication plugin for DeepSeek Harness (DSH), designed to address the lack of a stable communication mechanism in multi-agent collaboration. It enables standardized communication between agents through inter-session message passing and a name-based contact directory. The plugin’s core features include: the `session_message` tool for sending instructions across sessions, the `contacts` tool for managing the contact directory, and a local-only HTTP API for external agent invocation. After installation, the relevant features must be enabled in the configuration file. By replacing raw session IDs with “contacts,” supporting dynamic management at runtime, and limiting message length to prevent context bloat, the plugin provides a foundation for building complex multi-agent workflows.
