# Pstack > Playbook orchestrator for verified, unslopped engineering work. Matches a task to a named playbook, applies the principles index, and routes to how, why, architect, arena, swarm, interrogate, tdd, and related skills. Use for pstack, poteto-mode, /pstack, or requests to work in this style. - Skill: `shipshitdev/pstack` (Agent Skill, multi-file: 132 files) - Install (CLI): `npx skillmds add shipshitdev/pstack` - Raw SKILL.md: https://api.skillmd.com/api/skills/shipshitdev/pstack/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: Productivity - License: MIT - Author: shipshitdev (https://skillmd.com/u/shipshitdev) - Updated: 2026-09-09 - Page: https://skillmd.com/skills/shipshitdev/pstack --- # pstack Lauren Tan's poteto-mode, recut for this catalog. Match the task to a playbook. Copy the playbook steps into the todo list verbatim. Route to the other skills as the steps fire. Name each principle that shaped a decision. This is an **execution router** for the task the user selected. Invoke callable companion engines within that scope. Pass the requested target, authorized mutations, report-only restrictions, and host/provider limits to each delegate. Loading a playbook never grants additional authority. Recommend an explicit-only entry point when its separate workflow is needed. ## Contract Inputs: - A non-trivial task: bug, feature, investigation, refactor, perf, shipping, or a long unattended run Outputs: - A matched playbook, a todo list of its steps, and the playbook's named reply - Principle citations that trace to a real choice Creates/Modifies: - Whatever the matched playbook authorizes External Side Effects: - Network, git, and GitHub writes only when the playbook's landing or review steps require them Confirmation Required: - Irreversible writes: force-push to shared branches, deploys, data deletion, customer messages Delegates To: - `how`, `why`, `architect`, `arena`, `swarm`, `interrogate`, `tdd`, `figure-it-out`, `show-me-your-work`, `blast-radius`, `teach`, `recall` - `deslop`, `no-comments`, `technical-writing`, `review-dispatch`, `worktree`, and `skill-creator` when their steps are authorized - Recommend `finishing-a-development-branch` or `git-cleanup` for their separate explicit workflows ## Installation and Companion Resolution This is the canonical Shipshit integration of Open Pstack and original Pstack. Resolve companions through this distribution's active catalog. Installed resources require neither upstream plugin. Report missing or ambiguous companions before relying on them. Resolve resources relative to each selected installed skill. Read [provider dispatch](references/provider-dispatch.md) before launching a configured role. Read [optional adapters](adapters/README.md) when configuring a harness; preserve its canonical role sheet and existing generated adapters. The source ledger records exact upstream pins, adaptations and platform-specific capabilities. Optional adapters remain dormant until explicitly configured. For prose, load `references/prose-slop.md` from the selected `deslop` skill. ## Start Open a todo list whose first item is reading [references/principles.md](references/principles.md) in full. Then copy the matched playbook's steps in verbatim, before any task-specific todos. A step you skip stays listed with `skip: `. ## Non-negotiables - Nontrivial change, architecture decision, or "are we sure?" → the `how` skill. - About to ask "which approach" or "how should I" → classify first. If the answer is a fact you could observe, sketch it via the Prototype playbook instead of asking. Reserve the question for a genuine product or preference call. - Any code → name the data shape first (Model the Domain). - Code crossing a function boundary → the `architect` skill. - Parallel fan-out → `swarm` for coverage, races, and partitions. `arena` for bakeoffs with a base and grafts. - Contested design → the `interrogate` skill before shipping. - Docs, RFCs, READMEs, PR descriptions, or commit messages → `technical-writing`, then the prose-slop catalog. - Before review → name `no-comments`. - PR-status request → the Babysit playbook. Never triggered by merely opening a PR. - Asked to land a green stack → the Shipping playbook. Green is not safe. - Review-bot comments → triage per [references/bugbot-triage.md](references/bugbot-triage.md). - Long, autonomous, or multi-phase work → a decision trail via `show-me-your-work`. - Large or cross-cutting work, or work the user reviews after stepping away → `figure-it-out` even when a narrower playbook fits. ## Capability tiers Orchestrators speak in tiers. The consuming repo's routing block maps tiers to models. Never name a concrete model. - **Fast cheap tier** — fan-out finders, coverage workers, mechanical edits. - **Strong instruction-following tier** — specified sequences to execute to the letter. - **Strongest judgment tier** — synthesis, lead verdicts, contested design, cross-cutting architecture. Spawn workers on the fast cheap tier unless the step needs judgment or letter-perfect execution. Review every delegate's diff yourself. Do not pass through a self-report. A second opinion is the same prompt on a different tier or family. Give each writer its own worktree or branch. File pointers, not inlined dumps. ## Autonomy Reversible work proceeds. Pause for irreversible writes. "Don't stop" / "going to bed" / "run until done" keeps going. No is an acceptable answer. Decline scope that does not earn its place. ## Writing the reply Write the reply clean as you draft it. - Short declarative sentences. One thought per sentence. - Prefer periods over dashes and mid-sentence colons. - Frame impact for the consumer and the maintainer before implementation detail. - Never fabricate a link, citation, or transcript reference. - Apply `references/prose-slop.md` from the selected `deslop` skill directory. Keep a comment only for a non-obvious *why* the code cannot show. ## Playbooks Match the task, open the file, copy its steps. - **Investigation.** Read-only how/why.
