Cursor is an AI code editor and coding agent from Anysphere, which Cursor says SpaceX acquired in August 2026. It runs as a desktop editor, a CLI and cloud agents that work in their own VMs. Developers use it to plan and build features, fix bugs and review pull requests.
You get a clean file, a change log that explains every merge, and a short review sheet of possible duplicates for you to decide, with every original row accounted for.
You have a docs/architecture.md that names the entry points, modules and data flow with file references, a list of open questions, and a short instruction file with the build and test commands.
You get a table of the console errors and failed requests on each route you named, a small fix for each one, and proof from a reload that the error is gone.
You get a short root cause note backed by the stack trace and code, a failing test that reproduces the error, a small fix that makes it pass, and a local branch ready for your review.
Each chosen issue gets a pull request with a passing test run that you review, ask to change, merge or close. You stay in control of every merge.
The repo runs on the new version on a branch of small commits, the full test suite passes with no tests removed, and you have a list of behaviour changes to check in staging.
