pstack

Rigor over throughput. The point is to write less code, and to be able to prove the code you wrote works.

Original by Lauren Tan (poteto), MIT, from the Cursor plugin marketplace. This is a port: the principles and general skills are upstream's, the orchestration around them is rewritten for Claude Code and this repo. What changed and why: ATTRIBUTION.md.

How to use it

Read the principles below. Name the ones that shaped a decision, and say which choice each one changed. A citation with no decision behind it means you did not actually apply it — that is worse than not citing, because it reads as rigor without being rigor.

For any principle you actually apply, read its leaf skill in full (skills/principle-<name>/SKILL.md). The one-liners here are an index, not the content.

Principles

Core

• Laziness Protocol (principle-laziness-protocol). Refactoring, sizing a diff, or tempted to add abstractions, layers, or signal threading. Bias to deletion and the smallest change that solves the problem.
• Foundational Thinking (principle-foundational-thinking). Before writing logic: core types and data structures, scaffold-vs-feature sequencing, what concurrent actors share.
• Redesign from First Principles (principle-redesign-from-first-principles). Integrating a new requirement into an existing design. Redesign as if it had been foundational from day one.
• Subtract Before You Add (principle-subtract-before-you-add). Sequencing an addition, refactor, or rewrite. Remove dead weight first, then build on the simpler base.
• Minimize Reader Load (principle-minimize-reader-load). Reviewing or shaping code that's hard to trace. Count layers and hidden state, collapse one-caller wrappers, shrink mutable scope.
• Outcome-Oriented Execution (principle-outcome-oriented-execution). Planned rewrites and migrations with explicit phase boundaries. Converge on the target architecture, don't preserve throwaway compatibility states.
• Experience First (principle-experience-first). Product, UX, or feature-scope tradeoffs. Choose user delight over implementation convenience.
• Exhaust the Design Space (principle-exhaust-the-design-space). A novel interaction or architectural decision with no precedent. Build 2-3 competing prototypes and compare before committing.
• Build the Lever (principle-build-the-lever). Any non-trivial work. Build the tool that does or proves it (codemod, script, generator), not by hand; the tool is the artifact a reviewer reruns.
