qstack

Cursor skills for QuarkOS coding agents. Skills, a verification loop, and review modes. It sits beside pstack.

qstack is not a fork of pstack. pstack owns the playbooks (/poteto-mode, /swarm, /create-verification-skill). qstack ships skills that call that loop, plus OS verification and React review habits.

install

Install pstack first, then this plugin from the repo.

/add-plugin pstack

Point Cursor at this repository as a local or GitHub plugin source, or clone and add the plugin path for QuarkOS/Qstack.

get started

1. Install pstack and run /setup-pstack if you have not already.
2. Install qstack.
3. Invoke the skill that matches the job. Each skill is skills/<name>/SKILL.md.

/verify-on-os prove this on Ubuntu 24.04.

/react fix Fragment blur inside ShadowRoot. repro on main first, then dual-review before ready.

/lauren-mode review this compiler PR the way poteto would.

/eps1lon-mode review this Fiber PR the way sebbie would.

skills

The plugin manifest points skills at ./skills/. Layout matches pstack.

skill	use it when
/verify-on-os	prove a change on a fresh Ubuntu 24.04, Fedora 44, Windows 11, or Android 12 VM. SSH through Cloudflare Access to verify.emilioschwaiger.com.
/react	end-to-end React change: poteto-mode build, verify, swarm, open PR, lauren and eps1lon dual review, fix, publish ready.
/lauren-mode	match Lauren (GitHub poteto) React Compiler and rust-compiler habits.
/eps1lon-mode	match Sebastian Silbermann (eps1lon) Fiber, DOM, Flight, test, and CI habits.

verification

A verification skill has to exist before the loop is trusted. After a coding job, run a swarm of read-only verify agents against the project's verify-<app> skill (pstack /swarm and /create-verification-skill).

/verify-on-os is the homelab check: one SSH login, one fresh VM, destroyed on disconnect. /react runs the same verify-then-swarm loop, then dual-reviews.
