Curated skills from poteto's pstack (Cursor), rewritten for Claude Code: how/why/recall, adversarial review, architect/arena, decision trails and engineering principles.
Not in a marketplace yet, so it loads for one session with --plugin-dir.
Plugin pstack-picks in deadmade/dead-claude-skills. Commands read from the repo's manifest — 11 days ago.
architectSketch types, signatures, and module structure before code, then stay in the loop while implementation fills in. Use for /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 /arena, 'arena this', 'throw it in the arena', or when one attempt at a non-trivial artifact would lock in the wrong shape.
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.
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.
no-commentsSpawn Comment Sicko, fix accepted findings, and offer encodings for claimed constraints.
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-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-model-the-domainApply when writing stateful logic, or when code branches a lot or repeats a shape assumption across files.
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-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, exhaust variants, derive from authoritative schemas.
recallReconstruct your recent working context from your own chat history, live state, and the shared record (user reports, prior fixes, incidents), then hand back a tight current-state brief. Use for 'recall my work on X', 'catch me up', 'what have I been working on', 'where did I leave off', before start
show-me-your-workKeep a reviewable decision trail for long-running or unattended work: a TSV log with one row per decision (what, why, evidence, result). Local by default; commit it when a reviewer needs the trail to trust the result. Use for /show-me-your-work, autonomous or multi-phase runs, or work a human review
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
comment-sickoA deranged comment-hater that savors deletion and condemns workaround code.

Conductor skills that run the rest of the marketplace in order, with approval gates and resumable state: /feature-flow, /research-flow, /implement, /fix-flow and /upgrade build; /test-audit, /doc-audit and /harden check a branch or the whole repo; /self-review reviews your branch before a PR and /verify proves it is ready for one; /understand teaches a codebase; /learn saves what a flow taught. Also a writing skill (Williams and Bizup's Style) with a copyedit in which an Opus editor revises a document by that skill, and a code-only prose check on each Write or Edit of a Markdown file. Carries its skill packs, which only its conductors read, and installs the other plugins they use. Opt-in.
