dsh-ha-orchestrator: Model High Availability Fallback and Multi-Agent Orchestration

dsh-ha-orchestrator is a DeepSeek Harness workflow plugin (v0.12.2, MIT) maintained by Saktawdi. It automatically retries according to a fallback chain when model requests fail, and supports cooldown and provider circuit breaking. The orchestrate tool offers five orchestration modes: fanout, pipeline, supervisor, map-reduce, and router, with support for custom sub-agents, runId resumption, and run history. Recommended installation: dsh plugin --profile web add dsh-ha-orchestrator. It is suitable for long-task scenarios such as in-depth research, large codebase reading, and batch review.
