A set of skills by Lauren Tan (poteto) for Cursor and Claude Code. It teaches going deep with one agent first, then running many with proof. It is instructions for the agent you already use, with no runtime of its own, and poteto-mode is the router.
It shows that a lot of this can live in text. Its central claim is an order of work: earn trust in one agent's output, and only then parallelise. It also has the most exact public rules we found for what counts as proof before a merge.
Say it to your agent
“Install pstack with /plugin marketplace add cursor/plugins, then /plugin install pstack@cursor-plugins. Read me the shipping playbook, then tell me what we would need to change to follow it here.”
