**Open Pstack brings [Lauren Tan (@poteto)](https://x.com/poteto)'s [pstack](https://github.com/cursor/plugins/tree/main/pstack) to Claude Code and Codex.** Its job is to stay as close to her original work as possible while translating the parts that depend on Cursor.

Lauren built pstack from the skills she uses to ship code at Cursor. In a [55-minute interview with Denis Labelle](https://x.com/DenisLabelle/status/2091337807939706928), she says that she shipped 1,000 pull requests in one month after steadily improving how her agents work and verify their results.

If you want to go fast, go deep first.

Open Pstack is an unofficial community project that makes pstack work in Claude Code and Codex. If Cursor is your main coding environment, use [Lauren's original pstack](https://github.com/cursor/plugins/tree/main/pstack). If Claude Code or Codex is your main coding environment, use this repository.

What pstack does

pstack is a plugin for coding agents. It is not a new model or a hosted service. It gives your agent engineering rules, step-by-step workflows for different kinds of work, focused skills, and small local tools.

The normal entry point is `poteto-mode`. You give it a task in plain language. It then:

reads the task and chooses a workflow that fits;
learns how the current system works before changing it;
compares designs when the choice matters;
favors small, simple changes over extra machinery;
asks several models to challenge important decisions when useful;
runs the code and checks real behavior instead of stopping at “the tests pass”; and
