Codex vs Claude Code
One web feature, one repository, one acceptance test — measured for completion quality, intervention cost, and token spend.
Same task, same repository, same constraints. The result is judged by what ships — including the human work required to get it there.
The briefs are being prepared. No winner is named until prompts, artifacts, failures, costs, and verification output are recorded.
One web feature, one repository, one acceptance test — measured for completion quality, intervention cost, and token spend.
Editor-native flow versus terminal agent: compare codebase orientation, multi-file edits, review burden, and recovery from mistakes.
A controlled IDE comparison for context retrieval, multi-file changes, terminal work, and the cost of correcting an agent.
A narrower terminal-agent test focused on repository context, tool permission flow, failure recovery, and repeatability.
