Splitting Router and Worker Roles in a Node.js Coding Agent: Lessons from dsh-superagent

Coverage of DeepSeek's dsh-superagent names a router-worker coding agent pattern. This short walks through the post's Node.js reference implementation: a router that decomposes goals and sets hard budgets, a worker with a filtered tool surface, and a typed handoff contract that returns artifacts instead of reasoning transcripts. The post separates what the coverage confirms from what is reconstruction, and explains why the split only pays off when the boundary is enforced in code. The before scene is a minimal single-loop illustration; the after scene uses the post's typed envelope.
