Load and follow [`engineer-mode`](../engineer-mode/SKILL.md) in full, including its Principles index.\n\n`/poteto-mode` remains valid so existing muscle memory and prompts keep working. New writing should say `/engineer-mode`.\n\nAttribution for the original playbooks and principles lives in `engineer-mode` and in `skills/engineer-mode/references/licenses/NOTICE.md`.\n"
