Quellsprache: Englisch
Render the shape of code — module boundaries, the types that cross them, signatures, and a cited call graph — for code that already exists or a change about to be built. Every name, type, and path is read from source and cited, or marked NEW; bodies collapse…
Quellsprache: Englisch
Design, audit, and evolve physical source and package structures that expose real architectural boundaries while keeping related behavior together. Use when creating or reviewing repository trees, deciding where files or packages belong, reducing flat…
Quellsprache: Englisch
Model front-end and workflow logic as XState v5 statecharts and actors — when finite states earn their place (and when @xstate/store or a discriminated union is honest), event-first machine design, guards/actions/delays, invoke vs spawn, app-level actor…
Quellsprache: Englisch
Get a rigorous read-only second opinion on finished work through the host's available reviewer capabilities, preferably from a different model provider. Falls back to a fresh same-provider agent only when necessary and labels the reduced independence. Every…
Quellsprache: Englisch
Compose installed agent skills into one orchestrated multi-agent run: an agent graph where each node is a sub-agent that loads exactly one skill, edges carry structured data, and stages fan work out, adversarially verify it, and synthesize one deliverable.…
Quellsprache: Englisch
Planning work as vertical slices or an explicitly selected mechanism-reduction program in small, known-good increments, with independent pull requests or an optional stacked-PR topology across one or more ordered slices. Use when starting significant work,…
Quellsprache: Englisch
RED-GREEN-REFACTOR for production behavior changes, followed by mutation testing or alternate evidence once at the end-of-phase PR-readiness gate. Use before implementing new features, bug fixes, or any changed observable behavior, and as the governing…
Quellsprache: Englisch
WHEN deciding whether a PR, branch, diff, or current implementation satisfies an authoritative issue, specification, or decision contract; NOT for improving the written artifact, reconstructing meetings, general code review, or implementing fixes. Returns a…
Quellsprache: Englisch
Stable consumer-facing API and interface design patterns. Use when designing REST endpoints, cross-team boundaries, or any externally consumed or versioned service contract. Covers contract-first development, error semantics (RFC 9457), REST conventions,…
Quellsprache: Englisch
Design and protect browser-facing BFF and backend HTTP entry points: an explicit public/protected access classification for every production route, a composition-prepared endpoint registrar that installs session, Origin, Fetch Metadata, CSRF, and content-type…
Quellsprache: Englisch
Use when modifying existing code that lacks tests and you need to document its actual current behavior before making changes -- the legacy code dilemma where you need tests to refactor safely but the code was not written for testability. Specifically for…
Quellsprache: Englisch
Systematic CI/CD failure diagnosis using hypothesis-first investigation, local reproduction, and environment delta analysis. Use when a CI pipeline, GitHub Actions workflow, or build job fails; when tests pass locally but fail in CI; when diagnosing flaky…
Quellsprache: Englisch
Unix-composable CLI design patterns. Use when building CLI tools, designing command trees, implementing output layers, or testing CLI behavior. Covers stream separation (stdout/stderr), format flags (--json/--plain), exit codes, TTY detection, composability,…
Quellsprache: Englisch
WHEN diagnosing a reproducible or observable software failure outside a CI-pipeline-specific workflow; NOT for speculative cleanup, general code review, or speculative behavior changes presented as fixes. Preserves evidence, tests one causal hypothesis at a…
Quellsprache: Englisch
Create or audit maintainable diagrams when relationships, sequence, state, hierarchy, or quantitative comparisons are materially clearer visually than in prose. Selects a format the destination actually renders, preserves source authority, validates output,…
Quellsprache: Englisch
Domain-Driven Design patterns for TypeScript. Use when implementing ubiquitous language, value objects, entities, aggregates, domain events, domain services, or bounded contexts. Only applies to projects that explicitly use DDD. Do NOT use for simple CRUD or…
Quellsprache: Englisch
Research and compare established libraries, open-source tools and applications, managed services, and standard, framework, or platform primitives against an explicit bespoke baseline before committing to a material generic mechanism. Use for library/tool…
Quellsprache: Englisch
Event sourcing patterns for functional TypeScript — persist state as an append-only log of past events and rebuild it by folding them. Use when implementing a Decider write model, an event store, projections and read models, event versioning, or snapshots.…
Quellsprache: Englisch
Capture learnings, gotchas, and decisions in their durable owner while context is fresh. Use when documenting a discovery, recording a decision, deciding whether guidance is reusable or project-local, or routing knowledge to code, tests, a glossary, an ADR,…
Quellsprache: Englisch
Adversarially review an existing written artifact — stories, plans, acceptance criteria, specs, or design mocks — to surface missing states, unhandled edge cases, unstated assumptions, unverifiable criteria, and slices still too broad or horizontal. Works…
Quellsprache: Englisch
Discover and, with authorization, install agent skills from the open skills ecosystem. Use when the user explicitly asks to find or install a skill from the external skills ecosystem, asks whether an installable agent skill exists for a task, or wants to…
Quellsprache: Englisch
Use when existing code has untestable dependencies that prevent writing tests -- direct construction of collaborators, static or global function calls, tight coupling to external systems, or singleton access patterns. Specifically for identifying substitution…
Quellsprache: Englisch
Behavior-driven UI testing patterns across Vitest Browser Mode, Playwright E2E evidence boundaries, and DOM Testing Library. Use when testing any front-end application, writing UI or end-to-end tests, querying DOM elements, simulating user interactions, or…
Quellsprache: Englisch
Functional programming patterns with immutable data. Use when writing logic, data transformations, or encountering mutation bugs. Covers immutability violations catalog, pure functions, composition, early returns, and options objects. Do NOT over-apply heavy…
