Composer (and Cursor's Agent capabilities) let you describe a change and have Cursor plan and apply edits across multiple files, rather than editing one spot at a time. It is Cursor's answer to larger, autonomous tasks while staying inside the IDE.
Composer and Agent features evolve quickly through Cursor's releases, gaining new controls, context handling, and integrations over time.
Why it matters
Composer is how Cursor takes on bigger refactors and features, and it is a fast-moving part of the product. Tracking Cursor's changelog surfaces new agent capabilities as soon as they land.
