Head-to-head code review experiment compares three AI tools on same codebase
A video experiment compares three AI tools for code review: Codex, Claude Code, and Claude Code with Sextant. Each tool reviews the same codebase independently using identical prompts, with Codex then verifying the findings and judging which report provides more value.
Experiment Design
The experiment isn't just about counting bugs found. It tests how workflow and structure influence what an AI notices, how it prioritizes issues, and the overall usefulness of the final review. The three setups tested are:
- Codex
- Claude Code
- Claude Code with Sextant (a structured engineering workflow)
Codex serves a dual role: as one of the reviewing tools and as the judge that verifies findings from all three tools to determine which report is actually more valuable.
Practical Focus
This offers a practical look at how these AI coding tools perform in real development scenarios. The experiment is relevant for developers interested in automated code review, Claude Code, Codex, or structured engineering workflows like Sextant.
