@deepseek-ai/dsh-subagent-spawn
The spawn provider creates a fresh child Agent in the current process. The child has its own session, sees no parent conversation history, and reuses the host's agent factory and LLM/tool services.
Behavior
start(request) delegates to startInProcessRun with no seed and awaits publication before returning. The child receives parent working-directory/session lineage and inherits the parent model unless overridden, but starts with an empty conversation.
The shared driver owns depth checking, persona and tool-filter setup, structured output, required-signal cancellation, one-shot execution, result reading, and quiescent disposal. A startup rejection leaves no published child; provider unload after fulfillment does not revoke the holder-owned run.
Capabilities
Spawn advertises { outputSchema: true, depthLimit: true, toolFilter: true, persona: true } because it controls the child's creation window and can enforce all four features.

Known Limitations and Deferred Work
- Runs expose no
sendMessage/resume— the optional runtime capabilities are absent on in-process runs. - Fresh means no parent transcript — the child inherits cwd, lineage, model, and explicitly configured persona/tool restrictions, but none of the parent's conversation; use the fork provider when completed-turn context is required.
