Cursor Subagents
Define delegated subagents on a Cursor SDK agent via the `agents` field — `AgentDefinition`, MCP scoping, and model inheritance. Use when decomposing work across specialist personas.

Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

cursor-subagents
The Cursor SDK has first-class subagents: declare them on AgentOptions.agents and the parent agent decides when to spawn them. This is not a manual orchestration layer — the parent's planner picks subagents based on their description.
When to use
- Splitting a workload into specialist personas (planner, coder, reviewer)
- Scoping a subagent to a subset of MCP servers
- Running subagents on a different model from the parent
Configuration
- [[references/agents-field]] —
AgentOptions.agents: Record - [[references/agent-definition]] —

- [[references/model-inheritance]] —
