sdk

Notion embedded coding agents into its workspace in a few weeks using the Cursor SDK, so an @mention now plans, builds, tests and opens a PR without an editor in sight. The SDK turns the harness that powers Cursor into a callable runtime, and that is a bigger shift than any model release.

Cursor shipped @cursor/sdk in public beta on April 29 — the same harness that powers the IDE, scriptable from TypeScript. A working developer's tour of every surface, with code, gotchas, and ideas.
