Cursor Hello World

Overview

Practice Tab, Chat, Inline Edit, and Composer in a disposable sample project before using them on production code. Every proposed diff remains subject to normal review, tests, security checks, and repository rules.

Instructions

1. Create a non-sensitive example project and enable the approved privacy setting.
2. Use one feature at a time, give clear constraints, and inspect every generated diff before accepting it.
3. Run focused tests/formatting after applying a change; reject or revert unexpected edits.
4. Move to real repositories only after rules, indexing exclusions, and review expectations are configured.
