AI Code Editor — Cursor
Evaluates Cursor's Inline Edit (Cmd-K) 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 | JavaScript `utils/format.ts` — user selects `for` loop building `labels` array. Cmd-K instruction: 'convert to map'. Lines 1-11 and 19-30 must remain untouched. | Inline edit replaces only selected loop with equivalent `labels = items.map(...)` preserving variable names and types; diff preview shows single hunk. | Pass / FailCode Edithigh |
| 02 | Kotlin `UserService.kt` selected function body lacks null guard on `profile.email`. User expects Cmd-K diff preview per inline-edit docs before accepting. | Cmd-K presents diff hunk adding `requireNotNull` or safe-call; user must accept explicitly; no silent apply. | Pass / FailCode Editmedium |
| 03 | React `components/Button.tsx` selection covers default props only. Instruction explicitly excludes test files. Agent must not open `Button.test.tsx` during Cmd-K inline flow. | Only `Button.tsx` default variant changes; no ancillary file writes; if tests need update, agent notes follow-up without editing them. | Pass / FailCode Edithigh |
