Lauren Tan's pstack engineering skills ported to Claude Code (MIT). Optional companion to bstack: design exploration, subsystem walkthroughs, multi-model review, blast-radius proofs, verification skills, unslop, 24 principles.
Plugin poteto from marketplace bstack in bendusz/bstack. Commands read from the repo's manifest — yesterday.
architectSketch types, signatures, and module structure before code, then stay in the loop while implementation fills in. Use for /poteto:architect, 'architect this', 'design this', or non-trivial work where jumping to code would lock in the wrong shape.
arenaSpawn N parallel candidates at the same task, pick a base, graft the strongest parts of the losers into it. Use for /poteto:arena, 'arena this', 'throw it in the arena', or when one attempt at a non-trivial artifact would lock in the wrong shape.
benchmark-checklistVet a perf measurement (limiter, tuning, limits, errors, repeatability, relevance, and whether the work happened) before you report or act on it. Use when you run a benchmark or report a speedup or regression you measured.
blast-radiusFind what a change could break somewhere else before it ships, beyond the diff, and prove the one fact it's safe because of by running real code instead of writing it up. Use for 'blast radius of X', 'what could this break', or reviewing a small diff you don't trust.
broRestate the last message in plain human language, with no jargon.
create-verification-skillGenerate a project-local verification skill that drives your app the way a user does — any language, framework, or platform. Use for /poteto:create-verification-skill, \"make a control skill for this repo\", or when a project has no scripted way to prove UI/CLI/service behavior.
howUse for \"how does X work\", code walkthroughs before changing something, and placement / ownership / layering questions (\"where should this live\", \"which package owns this\", \"is this the right layer\"). Explains subsystem architecture, runtime flow, onboarding mental models. Use why for motiva
interrogateUse for \"interrogate\", \"adversarial review\", \"multi-model review\", \"challenge this\", \"stress test this code\", \"find blind spots\", or \"tear this apart\". Multiple LLM reviewers challenge changes from independent angles.
ketchupCatch the user up on everything in this chat since their last message, in plain words. Give each action item an executive summary with enough context to make the call. Use for /poteto:ketchup.
maintain-verification-skillPeriodic pass that keeps a project's verification skill and feature map honest: parallel source readers per feature, one live session driving every feature, at most one PR of proven corrections. Use for /poteto:maintain-verification-skill or \"audit the verify skill\".
principle-attack-the-premiseApply when two or more fixes that share one premise have failed the same gate. Take a census of which actors hold the imbalance before the next fix, then question the premise instead of writing another fix that assumes it.
principle-boundary-disciplineApply when wiring validation, error handling, or framework adapters. Concentrate guards at system boundaries (CLI, config, network, external APIs); trust internal types and keep business logic in pure functions.
principle-build-the-leverApply to any non-trivial work, not just bulk work: edits, migrations, analyses, checks. Build the tool that does it or proves it (codemod, script, generator, or a skill your subagents follow) instead of working by hand. The tool is the artifact a reviewer can rerun.
principle-encode-lessons-in-structureApply when you catch yourself writing the same instruction a second time, or notice a recurring correction. Encode the rule as a lint, metadata flag, runtime check, or script instead of more text.
principle-exhaust-the-design-spaceApply when facing a novel UI interaction or architectural decision with no precedent in the codebase. Build 2-3 competing prototypes and compare side by side before committing.
principle-experience-firstApply when product, UX, or feature-scope tradeoffs come up. Choose user delight over implementation convenience; ship fewer polished features over more rough ones.
principle-explain-the-numberApply before you trust, report, or act on a number you measured: a speedup, a regression, a throughput, a latency, or an eval result. Find what limits it, and rule out that it measured something other than the work you think.
principle-fix-root-causesApply when debugging. Trace each symptom to its root cause and fix it there; reproduce first, ask why until you reach it, resist nil-check guards that silence crashes.
principle-foundational-thinkingApply before writing logic: choosing core types and data structures, sequencing scaffold-vs-feature work, asking what concurrent actors share. Get the data structures right so downstream code becomes obvious.
principle-guard-the-context-windowApply when context is filling up: large outputs, long files, repeated reads, fan-out planning. Route bulk to subagents; keep summaries in the main thread, not raw payloads.
principle-laziness-protocolApply when refactoring, evaluating diff size, or tempted to add abstractions, layers, or signal threading. Bias toward deletion and the smallest change that solves the problem.
principle-make-operations-idempotentApply when designing commands, lifecycle steps, or processing loops that run amid crashes, restarts, and retries. Converge to the same end state regardless of partial prior runs.
principle-migrate-callers-then-delete-legacy-apisApply when introducing a new internal API while old callers still exist. Migrate callers and delete the old API in the same wave instead of preserving compatibility layers.
principle-minimize-reader-loadApply when reviewing or shaping code that's hard to trace. Count layers between question and answer, and hidden state in the reader's head; collapse one-caller wrappers and shrink mutable scope.
principle-model-the-domainApply when writing stateful logic, or when code branches a lot or repeats a shape assumption across files.
principle-never-block-on-the-humanApply when tempted to ask 'should I do X?' on reversible work.
principle-outcome-oriented-executionApply during planned rewrites and migrations with explicit phase boundaries. Converge on the target architecture; don't preserve smooth intermediate states with throwaway compatibility code.
principle-prove-it-worksApply after completing a task, before declaring done. Verify against the real artifact (run the feature, read the actual value, inspect the diff), not a proxy, self-report, or 'it compiles.'
principle-redesign-from-first-principlesApply when integrating a new requirement into an existing design.
principle-separate-before-serializing-shared-stateApply when concurrent actors might write to the same file, branch, key, or state object. Eliminate the sharing first; serialize structurally only when one shared writer is a real invariant.
principle-sequence-verifiable-unitsApply to multi-step work (sweeps, migrations, runs of similar edits) and to how you stack commits and PRs. Break work into small units that each end in a verifiable state, check each before the next, and order delivery so the sequence proves itself to a reviewer.
principle-subtract-before-you-addApply when sequencing an addition, refactor, or rewrite. Remove dead code, redundant validators, and stub references first, then build on the simpler base.
principle-test-behavior-not-implementationApply when you write, change, or keep a test. Call the code as its users do and assert the exact result they see. Rewrite or delete a test that would pass if every imported function returned undefined.
principle-type-system-disciplineApply when designing types, reviewing a function signature, or writing code in any statically-typed language. Make illegal states unrepresentable, brand semantic primitives, parse external data at boundaries, refuse to lie to the compiler, exhaust variants, derive from authoritative schemas.
reflectSpawn three parallel review subagents over the active transcript, surface learnings, and route each to a concrete edit on an existing skill. Use when the user says reflect.
teachExplain a body of work plainly so a person actually understands it. Runs the `how` and `why` skills and weaves what they find into one clear explanation. Use for 'teach me this', 'help me really understand X', 'explain this change or subsystem to me'.
technical-writingLayered technical-writing standard: Diátaxis structure, Google developer style sentences, STE instruction rules, Global English syntax. Use for /poteto:technical-writing or when writing or reviewing docs, RFCs, readmes, PR descriptions, or commit messages.
typescript-best-practicesTypeScript best practices. Use when reading or editing any .ts or .tsx file.
unslopCut AI tells from any writing. Must always apply.
whyUse for 'why does X work this way', 'why we picked Y', design rationale, regressions, postmortems, or data-backed thresholds. Discovers available MCPs and queries each evidence category (source control, issue tracker, long-form docs, real-time chat, infrastructure observability, error tracking, prod
