CursorAI/Subagent
- CursorAI's implementation of AI/Agent/Subagent: specialized agents with their own context, for task-specific work. Three ship built in —
explore for codebase search, bash for shell commands, and browser for browser automation over MCP. - Custom definitions are Markdown files in an
agents/ directory and can be packaged in a CursorAI/Plugin, per the plugins reference. - The declarable frontmatter surface is much smaller than Claude/Code/Subagent's, so a Claude agent definition loses fields on the way across.
- Support for a component is not the same as plugin parity: the plugins reference says these bundles work in the Cursor IDE and makes no equivalent claim for CursorAI/CLI. Test agents in the CLI independently of an IDE install.
