# @deepseek-ai/dsh-tool-subagent-control
English | [中文](README.zh.md)
The optional, globally named `send_message` tool: a thin adapter over `ctx.subagents.sendMessage()`. Provider-bound `@deepseek-ai/dsh-tool-subagent` instances register distinct delegation tools per transport; this separately loaded package registers one shared follow-up tool, so multiple delegation tools never register duplicate global controls. Its presence does not determine whether a delegation tool starts continuable work.
The tool performs no lifecycle routing. It attributes every follow-up as `{ kind: 'coordinator', senderSessionId: parent.id }`; the subagent service preserves that source while deciding between live delivery to the running activation's existing Task and a fresh Task that cold-resumes the durable child. The tool renders which route was taken and the relevant Task id. A delivery failure becomes an errored tool result stating the message was not delivered.
The tool performs no lifecycle routing. It attributes every follow-up as `{ kind: 'coordinator', senderSessionId: parent.id }`; the subagent service preserves that source while deciding between live delivery to the running activation's existing Task and a fresh Task that cold-resumes the durable child. The tool forwards its execution signal, so cancellation while live delivery awaits admission cancels the shared activation and settles only after the child reaches quiescence. The tool renders which route was taken and the relevant Task id. A delivery failure becomes an errored tool result stating the message was not delivered.
