dsh-consult: Evidence-First Multi-Model Advisory Plugin for DeepSeek Harness

`dsh-consult` is a standalone plugin for DeepSeek Harness designed to support critical decisions by introducing multi-model perspectives. It does not execute tasks; instead, once the user manually triggers the `/consult` command, the main agent investigates and prepares evidence, then consults multiple anonymous models in parallel to obtain a “second opinion.” The plugin is evidence-first and offers parallel independent review, anonymous synthesis, and permission isolation, making it especially suitable for high-leverage scenarios such as architecture selection, security boundary review, or release readiness checks. By explicitly controlling its triggers and resource consumption, it ensures cost predictability and data privacy.
