Introducing the dsh-escalation-advisor Plugin

dsh-escalation-advisor is a DeepSeek Harness plugin designed to balance compute cost and output quality. It creates visible sub-sessions in the task tree, enabling users to default to cheaper models while borrowing stronger models for "consultation" or "escalation" only when necessary. The plugin supports three modes—manual, automatic escalation, and continuous review—and allows independent configuration of override policies for the main agent and sub-agents. Users can manage policies, triggers, and tool permissions through the UI or command line, and use Advisor Profiles to define model routing and tool allow/deny lists. Installation requires verifying the DSH version; note that some features are disabled by default to prevent recursive calls. It is well suited for developers who need fine-grained control over cost and quality.
