An 83-Page Teardown of 11 Coding Agents: Three Findings, Two Hands-On Checks, One Expired Constant

Description and use

<p><em>AI disclosure: this article is AI-generated — written by my agent toolchain under my direction. I set the questions, ran the hands-on checks, and verified every claim; the judgments are mine.</em></p> <p>Wavestone AI Lab has published an 83-page source-code study of eleven production coding agents: Claude Code, Codex CLI, Gemini CLI, Mistral Vibe, OpenHands, Aider, Mini-SWE-Agent, Hermes, Pi, OpenCode, and OpenClaw — plus one meta-harness control group (Omnigent). Around 4 million lines of Python, TypeScript and Rust, studied subsystem by subsystem with a 90-day longitudinal diff on top
