Design, implement, review, and migrate XState v5 state machines and statecharts in TypeScript using modern v5 patterns. Use this whenever the user mentions XState, actors, state machines, statecharts, guards, transitions, workflows, or Stately, or is modeling non-trivial UI/app/process logic in a codebase that uses XState. Prefer a short machine sketch before code when requirements are fuzzy. If the problem is too simple for a state machine, say so and recommend @xstate/store instead.
[Pragmatic DDD Architecture] Guide for creating Next.js Server Actions exactly tied to zod, neverthrow, and the domain architecture. Use when creating or editing any file in presentation/actions/. Covers "use server" placement, unknown parameters validated with `zod`, discriminated union response types, auth-first pattern, Value Object validation with TypeScript narrowing, use-case error mapping via `assertNever`, serviceContainer invocation, and revalidation strategy.
Production-grade Playwright in TypeScript: Page Object Model, fixtures, auto-waiting, user-facing locators, parallel execution, CI integration, visual testing, accessibility. Includes explicit "do not" list for AI agents and 2025-2026 feature awareness. Use when: "Playwright," "browser testing," "E2E test," "end-to-end," "page object." Related: visual-testing, ci-cd-integration, api-testing, test-reliability, accessibility-testing.
MUST be used whenever reviewing a Dune app for code quality, maintainability, or clean code issues — before a PR review, after a feature is complete, or when the user asks for a code review. Do NOT skip linting steps. Triggers: code quality, code review, clean code, refactor, maintainability, technical debt, any type, naming, dead code, duplication, DRY, single responsibility, component size, lint, linting, TypeScript strict, dependency injection, file structure.
Use when a PinMe project (Worker TypeScript) needs to integrate user authentication — creating email/password users, verifying id_tokens, querying user info, or listing users via Identity Platform auth proxy APIs.
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 projects without domain modeling.
Use when writing, fixing, editing, or refactoring React components, hooks, state, effects, JSX, or React tests in TypeScript projects.
Use when writing, fixing, or editing TypeScript comments or TSDoc, especially commented-out code, stale docs, metadata comments, redundant comments, TODO banners, or unclear comment value.
Use when fixing, editing, changing, or debugging existing TypeScript code and keeping changes small and proportional to what was touched.
Node.js/TypeScript SDK for the iii engine. Use when building workers, registering functions, or invoking triggers in TypeScript or JavaScript.
Use this skill when the user asks about Goldsky Compose — the offchain-to-onchain TypeScript framework for onchain oracles, keepers, circuit breakers, and cross-chain automation. Triggers on: 'goldsky compose', 'compose.yaml', 'compose deploy/init/dev', 'compose task', 'cron task onchain', 'sponsored gas', 'writeContract from TypeScript', 'build a price oracle', 'resolve prediction market', 'onchain event listener', 'HTTP-triggered task', 'smart wallet'. Also use when the user wants to run TypeScript against EVM chains with managed gas, schedule onchain writes via cron, react to onchain events, or deploy a serverless task with secrets and a smart wallet. For debugging a broken app, use /compose-doctor. For manifest/CLI/API lookups, use /compose-reference. Do NOT trigger on Goldsky Turbo, Mirror, Subgraphs, Edge, or Datasets — those belong to their respective skills.
Adds Dataverse tables to a Power Apps code app with generated TypeScript models and services. Can also create new Dataverse tables. Use when connecting to Dataverse, adding tables, creating schema, or querying Dataverse data.
