dsh-routed-subagent

DeepSeek Harness's stock subagent and subagent_fork tools lock every child to the parent's preset—persona, prompt sections, skill catalog, and tools all inherited. When you need a child to run under an entirely different role, tool surface, or model, the native path offers no switching lever. dsh-routed-subagent fills that gap with a custom async mount channel that swaps the child's full composition—identity, mission section, skills, and tools—onto the target preset in one step, rather than copying a persona string.

Beyond preset routing, the plugin handles several practical concerns: per-call model and provider overrides with a fail-fast availability pre-check so you never stare at an opaque child error; background-by-default dispatch that returns a job id immediately, keeping the conversation free to work or fork more children in parallel without the abort cancelling the child; fork mode that seeds the child with the parent's completed turns before mounting the target preset; and continuable mode that mints a durable subagent id you can resume later via send_message. The engine parameter additionally lets you dispatch the subagent to an external CLI—codex's app-server stdio loop, the Claude Code SDK, or CodeBuddy's stream-json CLI—running a full agent pipeline outside the harness kernel.

This plugin is aimed at teams and solo users orchestrating multiple presets inside DeepSeek Harness, automation maintainers who want a single delegation entry point that fans out to different CLI engines, and anyone who needs same-session, different-role, different-model, different-engine flexibility without scattering bespoke config across profiles. If your workflow stays within one preset and never touches model overrides or external engines, the stock subagent tool is sufficient; the moment your work requires compositional freedom across presets, models, and engines, dsh-routed-subagent removes a great deal of boilerplate.
