Preface

DeepSeek Harness (DSH) supports opening multiple parallel sessions within the same instance. For these sessions to communicate with each other, hand off work, or perform verification, a dedicated mechanism is required. dsh-team-link (original name dsh-session-link-pro) is such a mechanism, providing DSH with cross-session messaging, session deep links and export, team rotation, and identity management capabilities.

What Is It

This is a DeepSeek Harness (DSH) plugin designed to address multi-session parallel collaboration.

  • Plugin name: shenhuanageshei/dsh-session-link-pro (the GitHub repository was renamed to dsh-team-link on 2026-09-18)
  • Core value: Session deep links + full session export (markdown/JSON) + approved cross-session messaging with pairing for DeepSeek Harness (dsh).
  • Maintainer: shenhuanageshei
  • License: MIT

Core Features

This plugin primarily addresses multi-session parallel collaboration. Its core capabilities include:

  1. Cross-session messaging and pairing: Supports cross-session messaging and requires a pairing mechanism.
  2. Session deep links and export: Provides deep links to sessions and supports exporting full sessions as Markdown or JSON.
  3. Cross-process team coordination: Supports team coordination across processes.
  4. Team rotation and identity management: Supports role rotation and the lifecycle and decoupling management of identities.
  5. Human-in-the-loop authorization points: Authorization is initiated by a human click and uses a fail-closed model.

Difference from Built-in Features

The plugin is orthogonal to DSH’s built-in Agent Teams; it solves cross-session collaboration rather than task division within a single session.

  • Built-in Agent Teams: Solves task division within a single session. The TeamId is attached to the log of the Lead session and does not involve cross-process coordination.
  • dsh-team-link: Solves collaboration across sessions and across processes. Team information is not attached to any session, requiring a strict trust model (dual-gate approval, pairing, one-time token rotation, and symmetric revocation of retired identities).

Use Cases

Based on verified use examples, this plugin is suitable for the following scenarios:

  1. Multi-session parallel collaboration: For example, the rotation + autonomous night-shift advancement in Case 1, where deep links and the rotation mechanism keep long-running tasks connected across session switches.
  2. Cross-session mutual error checking: For example, the four-line parallel workflow in Case 2, where different sessions question each other and capture errors the other missed.

Technical Notes

  • Historical version compatibility: Historical tool names session_link_pro_* and message prefixes slp- remain unchanged for the audit/provenance chain, with no write-back.
  • Dependency requirements: Depends on specific versions of DeepSeek Harness related API packages.
