Toss Place FE Superpowers

A frontend assignment workflow kit for Toss Place style take-home assignments. It helps with planning feedback loops, product-focused assignment strategy, requirement analysis, assumptions, trade-offs, README rationale, stack selection, cache-efficient Next.js RSC architecture, Simple FSD, API design, component boundaries, React performance review, test quality review, parallel agent orchestration, review-fix loops, feature-sized commits, git delivery, reliability review, and final polish.

What it installs

Skills (18)

  • api-layer-designer

    Design a domain API layer that separates pure API call functions, React Query hooks, query keys, API-bound domain types, and mappers under the entities layer while keeping common code in shared.

  • assignment-forensics

    Analyze a frontend take-home assignment before implementation. Extract explicit requirements, hidden evaluation points, user flows, business rules, reliability risks, edge cases, MVP scope, and submission checklist.

  • commit-push-pr-agent

    Create feature-sized commits, push, and open a pull request only when the user explicitly asks for commit, push, PR creation, git delivery, or a dedicated git delivery subagent after verification.

  • component-boundary-planner

    Plan React component boundaries based on state ownership, re-render minimization, Server/Client Component boundaries, domain responsibility, and assignment maintainability.

  • final-submit-polisher

    Polish a frontend assignment before submission by checking README, scripts, verification commands, implementation scope, trade-offs, known limitations, and final diff quality.

  • next-rsc-architect

    Design a Next.js App Router architecture using Server Components by default, small Client Component boundaries, cacheable server fetching, ISR/revalidate, and React Query only where client-side server state is needed.

  • offline-edge-case-checker

    Check frontend implementation against offline store, POS, kiosk, table order, payment/order, network instability, and device interaction edge cases.

  • parallel-assignment-runner

    Orchestrate a frontend take-home assignment with Codex subagents only when the user explicitly asks for parallel agents, an agent team, multiple agents, delegated parallel work, review loops, or an end-to-end assignment execution workflow.

  • planning-feedback-loop

    Create, refine, and validate an executable plan before implementation when the user explicitly asks for planning, a planning feedback loop, design review, architecture planning, refactoring plans, migration planning, plugin design, AI workflow design, or pre-execution validation.

  • product-assignment-strategist

    Analyze and plan product-focused frontend take-home assignments before implementation, especially when an existing codebase, design system, mock API, assumptions, trade-offs, README decisions, or reviewer-friendly code are important.

  • react-best-practices

    Review, refactor, or plan React and Next.js code using Vercel-style impact-ordered best practices. Use for performance reviews, async waterfalls, bundle size, RSC boundaries, cache strategy, client data fetching, re-render risks, or React/Next.js architecture quality.

  • readme-rationale-writer

    Write or review a frontend assignment README so it explains design rationale, API and cache strategy, React Query trade-offs, FSD boundaries, error handling, test strategy, known limitations, verification evidence, and AI usage validation.

  • reliability-first-planner

    Create a reliability-first implementation plan for a frontend assignment, focusing on correctness, failure states, duplicate action prevention, stable state transitions, and maintainable UI logic.

  • review-fix-loop

    Run an implementation review, fix, and verification loop for a frontend assignment after code has been written, with findings-first review, up to 3 iterations by default, and clear stop or escalation conditions.

  • simple-fsd-architect

    Design a lightweight FSD-inspired frontend architecture using app, pages/views, widgets, entities, and shared without over-engineering.

  • stack-setup-planner

    Choose the simplest suitable frontend stack for an assignment, including Vite, Next.js, TypeScript, Tailwind, Emotion, React Query, Vitest, Jest, PNPM, and Yarn Berry.

  • test-quality-reviewer

    Review frontend assignment tests for meaningful regression coverage, state transitions, pure logic validation, accessibility states, and low-value or bug-locking test smells.

  • toss-fe-code-review

    Review frontend code like a Toss Place frontend reviewer, prioritizing correctness, reliability, maintainability, state boundaries, RSC usage, API layer design, and edge cases.
