create-subagent

Create a custom AI subagent by defining unique system prompts and configurations that establish task specialization and context isolation. This isolates the agent's focus from your main conversation, allowing dedicated behaviors like code review or debugging within the Cursor environment.

Context isolation runs specialized AI assistants in separated environments to preserve your main conversation context. You need context isolation when deploying task-specific subagents like a security auditor, ensuring the main AI assistant's focus remains unaffected by specialized prompt instructions.

Yes, you can deploy custom agents at both project-level and user-level scopes. This deployment flexibility allows you to configure subagents with defined file formats tailored for specific repository tasks or broader global behaviors across your entire Cursor environment.

Best practices for writing subagent descriptions involve defining clear roles and specific behaviors using supported file formats. Structured system prompts ensure the subagent maintains strict task specialization, preventing context bleed and keeping the AI focused on its designated role.

Set up a dedicated code reviewer by creating a subagent with a system prompt focused on quality and best practices. This specialized agent operates with context isolation to review code without disrupting your main Cursor conversation or development workflow.
