// Open Pstack trainer
Train the method. Then invoke it.
Open Pstack 1.2.0 tracks Cursor pstack 0.14.3. This page is for Claude Code and Codex. Always use the /pstack: prefix. No login. No buy wall.
Source of truth: ericlitman/open-pstack (Eric Littman), for Claude Code. Cursor’s official pstack (/add-plugin pstack) is a different plugin. Do not install that and think you have this harness. Thought→plan is shadcn/improve; this trainer stays the pstack teaching surface.

A plugin, not a model. One door.
Open Pstack is a plugin. The door is /pstack:poteto-mode. It matches a playbook, copies those steps into the todo list verbatim, and routes to other skills. You do not invent a second process.
This is Eric Littman’s ericlitman/open-pstack for Claude Code. Cursor’s official pstack (/add-plugin pstack) is a different plugin.
The only automatic behavior is a Claude Code SessionStart hook on startup, /clear, and compact. It injects a short routing reminder toward poteto-mode. It loads no state. It does not pause. It does not resume.
Everything else is invoke-only. If you do not invoke it, you do not have it. There is nothing to turn on. Building a boot-state tool, a custom handoff skill, a compaction hook, or a homemade multi-model panel is the failure mode.
- Cold boot / resume
- /pstack:poteto-mode matching session-pickup
- Pause / compaction coming
- pause-safely playbook
- Rebuild recent context
- /pstack:recall
- Long / autonomous
- show-me-your-work plus autonomous-run or orchestrate
- How does X work
- /pstack:how (critique mode when you want issues)
- Why was this built this way
- /pstack:why
- PR status / get it green
- babysit playbook; /pstack:babysit standalone also exists
- Land a green stack
- shipping playbook. Green is not safe.
