Lab Report: Claude Code vs. Cursor Agent on 50 Full-Stack Refactors

At MyGearHut Labs, we don't rely on synthetic benchmarks. We designed an empirical test harness composed of 50 real-world engineering tasks extracted from active enterprise client codebases.

Benchmark Results Matrix

| Metric | Claude Code CLI (v1.0) | Cursor Agent Mode (0.46) |

|---|---|---|

| First-Pass Test Suite Pass Rate | 88% (44/50) | 82% (41/50) |

| Multi-File Context Consistency | 94% | 80% |

| Single-File Edit Latency | 14.2s | 5.8s |

| Self-Correction on Failed Tests | 92% | 68% |

| Average Token Cost per Refactor | $0.42 | $0.28 |

Key Findings

1. Test-Driven Self-Correction

The critical advantage of Claude Code CLI is its ability to execute npm test or pytest in the terminal, capture runtime stack traces, and iteratively modify code until the build succeeds without human intervention.

2. Speed vs. Depth

When developers are actively writing code and need instant component scaffolding, Cursor's inline UI provides near-zero friction. For large migrations (e.g., migrating from Tailwind v3 to v4 across 100 components), Claude Code's autonomous background runner is unmatched.
