Rigorous engineering orchestrator ported from Lauren Tan's pstack (poteto-mode): reads your task, picks one of 23 playbooks (bug fix, feature, refactoring, perf, investigation, prototype, babysit, shipping, autonomous run, orchestrate, and more), routes to bundled procedures (how, why, architect, arena, swarm, interrogate, unslop, technical-writing, show-me-your-work, tdd, and others), and applies 24 engineering principles. Self-contained: no plugin install, no sibling skills required, works with any agent that reads skills.sh-format SKILL.md files. Use whenever a task needs rigor: nontrivial code changes, architecture decisions, debugging, reviews, PRs, long autonomous runs, or "work like poteto", "poteto-mode", "pstack".

# Pstack

An orchestrator for high-rigor engineering work, distilled from [Lauren Tan's](https://x.com/poteto) pstack plugin into one self-contained skill. It turns an agent into a disciplined engineering team: deep before fast, evidence before claims, small verified units before big bets. The goal is less, higher-quality code.

This skill is **sticky**. Once invoked it stays on across turns, applying itself when a playbook matches or the task needs rigor, staying out of the way otherwise. Opt out any time by saying so.

Everything referenced here ships inside this skill:

- `playbooks/*.md` — the step-by-step workflows. Copy matched steps verbatim.
- `references/principles.md` — the full text of the 24 principles indexed below.
- `references/bugbot-triage.md` — bot-review triage.
- `references/skills/*.md` — bundled procedures named by bold lowercase words (`how`, `why`, `architect`, `arena`, `swarm`, `interrogate`, `unslop`, `no-comments`, `technical-writing`, `show-me-your-work`, `figure-it-out`, `tdd`, `blast-radius`, `recall`, `reflect`, `teach`, `bro`, `typescript-best-practices`, `create-verification-skill`, `maintain-verification-skill`, `create-formal-verification-skill`, `maintain-formal-verification-skill`, `statechart`, `in-your-own-words`, `sharpen`, `setup-pstack`, `benchmark-checklist`, `correct`, `ketchup`, `ketchup-video`, `poteto-help`). Read the file when a step routes to one.
- `references/harness/*.md` — one tool, subagent, model, and path mapping per harness (`claude-code.md` today). When a step names a Cursor tool or path and you run in that harness, read its file once per session and map names with it.
- `scripts/log.sh` — decision-log helper. `scripts/worktree-audit.sh` — disk reclaim audit.
