Web & Frontend

nexadevapp Skill

Runs a comprehensive implementation audit for a delivered use case. Checks Definition of Done, i18n completeness and correctness, error message i18n, accessibility, visual fidelity against the design, and loading/error states. Run after /deliver-use-case or before /merge-use-case for a quality deep-dive. Results are advisory — Critical and Major findings should be fixed; Minor findings are observations.

nexadevapp Skill

Implements use cases and fixes bugs by creating Next.js pages, components, API route handlers, and server actions. Use when the user asks to "implement a use case", "fix a bug", "build the UI", "create an API endpoint", "write a page", or mentions Next.js implementation, App Router, server actions, or full-stack implementation.

nexadevapp Skill

Sets up server-side internationalization infrastructure for Next.js App Router using next-intl. Creates middleware locale detection, translation file structure, type-safe utilities, and routing configuration. Run before implementing use cases so that all feature code produces localized pages from the start. Use when the user asks to "set up i18n", "add internationalization", "add translations", "set up localization", "add multi-language support", or mentions i18n, internationalization, localization, or multi-language.

nexadevapp Bundle

Creates Vitest integration tests for Next.js API route handlers, server actions, and components using Testcontainers for external dependencies. Use when the user asks to "write integration tests", "test with a real database", "create Vitest integration tests", or mentions Vitest integration testing or Testcontainers. Unit tests are created by the implement skill.

nexadevapp Bundle

Creates screen design specifications as standalone HTML artifacts from the project wireframe. Uses Playwright to open the wireframe, identify the section relevant to the current use case, and produces a self-contained HTML design file faithful to the wireframe's layout and enriched with states, data mappings, and interactions from the use case specification. Uses a separated CSS theming approach — HTML references a theme switcher CSS file and a Tailwind config, so changing the theme across all designs requires only swapping CSS files. Use when the user asks to "design a screen", "create a wireframe", "define the UI", "design the frontend", or mentions screen design, wireframes, UI layout, or frontend design.

nexadevapp Bundle

Creates Playwright browser-based end-to-end tests for Next.js pages covering complete user journeys from start to finish. Use when the user asks to "write Playwright tests", "create e2e tests", "write integration tests", "test in the browser", or mentions end-to-end testing, browser tests, UI integration tests, or Playwright for Next.js.

nexadevapp Bundle

Sets up arch-unit-ts architectural testing for a Next.js project. Detects the project layout, proposes a default rule set derived from the Next.js project structure conventions, asks the user to confirm or extend the rules, scaffolds the architecture spec, and installs a dedicated Husky pre-commit hook that runs the rules before every commit. Use when the user asks to "set up arch-unit", "add architecture tests", "enforce module boundaries", "set up arch-unit-ts", "add an architecture lint", or mentions arch-unit, ArchUnit, architectural rules, dependency rules between modules, layered architecture enforcement, or hexagonal architecture testing in TypeScript.

nexadevapp Bundle

Generates a high-quality wireframe as a single-page HTML file showing all screens, their spatial layout, and navigation flow. The wireframe establishes screen structure, component placement, and information hierarchy with production-grade visual design powered by the frontend-design skill. Supports incremental updates: new screens can be added without destroying existing sections. Use when the user asks to "create a wireframe", "generate a wireframe", "sketch the screens", "layout the UI", or mentions wireframe, screen layout, UI skeleton, or low-fidelity mockup.

nexadevapp Skill

Retrofits an existing Next.js codebase into the Nexa Agentic Engineering methodology by reverse-engineering a requirements catalog, entity model, use case diagram, and use case specs from the live code (and from BMAD-method artifacts under `_bmad/`, when present), then auditing cross-cutting infrastructure and creating thin-pointer GitHub issues for already-shipped work. Use when the user asks to "onboard this codebase", "onboard an existing app", "retrofit Nexa onto my project", "adopt the Nexa pipeline for an existing Next.js app", "reverse-engineer requirements from code", or mentions bringing a brownfield or already-built Next.js project under Nexa/`/deliver-use-case`/`/resolve-bug` for future work.

nexadevapp Skill

Builds the Next.js request interception layer with authentication, authorization, security headers, error tracking, and request context enrichment. Run before implementing use cases so that feature code can rely on cross-cutting infrastructure. Use when the user asks to "set up middleware", "add auth middleware", "build the middleware layer", "add security headers", "protect my routes", "add login redirect", "secure my API routes", "set up route guards", or mentions middleware, authentication guard, route protection, or RBAC middleware.

Relic Artifacts: The house standard for artifacts — small interactive pages agents generate. The minimal version is one self-contained static HTML file; artifacts can grow a small server or extra files when the job genuinely needs them.

davie521 Bundle

Evaluate design from a UX perspective, assessing visual hierarchy, information architecture, emotional resonance, cognitive load, and overall quality with quantitative scoring, persona-based testing, and actionable feedback. Use when the user asks to review, critique, evaluate, 评审, or give feedback on a design or component. Diagnosis only — critique judges whether the experience works; to produce or modify a design, use ui-ux-pro-max.

davie521 Bundle

Create dense, printable A4 landscape cheatsheets from Markdown using a custom syntax with multi-column layout. Use when the user asks to create a cheatsheet, revision sheet, crib sheet, or condensed reference document for exams, courses, or technical topics. Supports math formulas, tables, highlights, notes, and multi-page output. Converts Markdown to styled HTML and exports to PDF for printing.

creatorland Skill

Build a shareable, good-looking microsite / media kit from creator audience data. Use when the user wants to "make a media kit", "build a roster site", "create a shareable creator/roster page", "wrap deck for these creators", "turn this roster into a website", or "a site like the audience report page". Renders one creator or a full roster into a Cowork HTML artifact styled after the audience-report layout. Pulls audience reports for any creators that need them (paid — preflight the cost).
