Handbook
subagent — Cursor subagent
Specialized child agent (explore, shell, bugbot, etc.) launched via Task tool for bounded parallel work.
What it is
Parent agent delegates with subagent_type; model tiering may use cheaper subagents for mechanical edits.
When people say this
When L/XL plans propose tiering — high model for design, subagent for migration breadth.
Where it lives
Cursor agent Task tool; forge-planning-standards model-tiering table
How it fits the ecosystem
forge-triage.mdc gates expensive orchestration on XS–XL size before spawning many subagents.
Typical usage in plans and chat
XL plans should justify subagent fan-out; XS/S often inline without Task tool.
