ARIS (Auto-Research-In-Sleep) vs Ponytail
Markdown-only skills for autonomous machine learning research. A skill that makes coding agents write the smallest change that solves the task. Compare the capabilities you need, then check hosting, licensing and maintenance. This pair is shown for browsing but is not indexed (not among the leading projects of a shared category).
| Attribute | ARIS (Auto-Research-In-Sleep) | Ponytail |
|---|---|---|
| Purpose | Markdown-only skills for autonomous machine learning research. | A skill that makes coding agents write the smallest change that solves the task. |
| Documented capabilities | Idea discovery workflow, Experiment runs, Cross-model review loops, Also ships as a CLI and plugins | Smallest-change coding rules, /ponytail-review for changed code, /ponytail-audit for a whole repository, Small tests kept for risky logic |
| Best-fit workflow | ML researchers who want agents to run long research loops. | Developers who want agents to add less code and fewer dependencies. |
| Check before choosing | Recent Codex CLI versions changed the reviewer entry point. Read the README's compatibility notes first. | The project's benchmark numbers are its own. Install only from the official GitHub repository or npm package, as its README warns about copies. |
