Pstack

pstack

i'm poteto. i'm not a president or ceo, but i've worked with millions of lines of code at Meta, Netflix, and Cursor. i'm also on the react core team where i help build and maintain react compiler.

there's a growing sense that ai writes too much slop code. i agree. i don't want to ship like a team of twenty slop artists. throughput without quality is not a goal i aspire to. if you want to go fast, go deep first.

pstack is my answer. these are the same skills i use everyday to ship high quality code at Cursor. this turns cursor into a real engineering team. the goal is not to maximize loc, in fact it's the opposite. pstack helps you write less, but higher quality code.

pstack gives you fearless parallelism. when you can go deep on one agent and trust it to write good, verifiable code, you can truly parallelize with confidence. start multiple agents up with poteto-mode and trust that they'll apply rigorous engineering principles to their work.

cursor gives you the best of all worlds. every frontier model has its strengths and weaknesses. use any model with pstack. in fact, many of my skills use multi-model workflows to take advantage of each model's unique strengths.

fork it. improve it. make it yours. PRs are welcome!

install

/add-plugin pstack

in claude code:

/plugin marketplace add cursor/plugins
/plugin install pstack@cursor-plugins

claude code prefixes plugin commands and agents, so /poteto-mode is /pstack:poteto-mode. the claude code adapter maps every other cursor name.

claude code installs a generated copy of pstack from harness/pstack/ at the repository root. after changing skills/, agents/, docs/harness/claude-code.md, or plugin.json, run node scripts/generate-pstack-harness-trees.mjs from the repository root and commit the result. ci fails until you do.

get started

two steps:

1. run /setup-pstack, pick a reasoning budget, and choose which models you want.
2. use /poteto-mode whenever you're doing anything that requires rigor.
