AI Code Editor — Cursor
Evaluates Cursor's Codebase Indexing across 6 scenario-based test cases, each graded against an expected-behavior rubric by an LLM judge, from Corsac's AI Code Editor eval coverage.
About Cursor
Cursor is an AI code editor built on VS Code: predictive Tab completion, inline edits, and an agent mode that plans and executes multi-file changes with terminal access, codebase indexing, project rules, and MCP integration.
Sample tests· showing 3 of 6
| # | Input | Expected behavior | Check |
|---|---|---|---|
| 01 | Go monorepo — real definition in `internal/http/retry.go`. Another package has comment mentioning 'retry policy' only. Agent must cite defining file, not comment-only match. | Returns `internal/http/retry.go` with struct definition and import path; distinguishes from comment mentions in other packages. | Pass / FailRetrievalhigh |
| 02 | File exports `createDraftInvoice`, `finalizeInvoice`, and internal helper `buildLineItems` (not exported). Question is specific to exported API. | Answers `createDraftInvoice` with signature line number from file; does not claim `buildLineItems` is public. | Pass / FailRetrievalmedium |
| 03 | After `git checkout feature/new-auth`, `middleware.ts` moved `src/middleware.ts` → `src/auth/middleware.ts`. @codebase answer still references old path until reindex. | Detects path mismatch vs live buffer; recommends reindex or uses open buffer; answers with new path after refresh. | Pass / FailRetrievalhigh |
