Review code (your own or others') for correctness, design, and risk before it merges. Use when reviewing a diff or pull request, doing a self-review before opening a PR, or giving structured, prioritized feedback.
Skill Claude CodeCodex
Design reusable React component APIs that scale — compound components, lifted state, generic context, explicit variants. Use when a component is growing boolean props (isThread, isEditing…), when building a component library, or when reviewing component architecture. Includes React 19 API changes.
Skill Claude CodeCodex
Write clear, atomic commits using Conventional Commits. Use when committing changes, writing or rewriting a commit message, or splitting work into reviewable commits.

Design and build data-dense dashboards, back-office, and admin apps that surface the few metrics a decision needs. Use when laying out an admin/console screen, KPI strip, chart grid, data table, sidebar nav, or reviewing the visual design and information hierarchy of an internal/operational UI.
Skill Claude CodeCodex
Architect a scalable, themeable design-token system — primitive → semantic → component layers, CSS variables, a 4px spacing/type scale, and dark mode. Use when setting up or refactoring a project's tokens, naming color/spacing/radius values, wiring tokens into Tailwind/shadcn, enabling theme switching, or killing…
Skill Claude CodeCodex
Design distinctive, production-grade frontend interfaces that don't read as templated AI defaults. Use when bootstrapping a frontend app, building or restyling a landing page, marketing site, hero, brand-forward product surface, or any UI where visual identity matters — choosing palette, typography, layout, motion…
Skill Claude CodeCodex
Test web frontends (React/Next.js) effectively. Use when writing or fixing unit/component tests with Vitest + Testing Library, end-to-end tests with Playwright, or deciding what to test in a frontend app.
Skill Claude CodeCodex
Write idiomatic, modern Go (1.25+/1.26) using current language and stdlib features. Use when authoring or reviewing Go code, choosing between stdlib and third-party helpers, working with generics, iterators, contexts, or error wrapping in this workspace.
Skill Claude CodeCodex
Write clear, fast, deterministic Go tests including mandatory repo integration tests (x/testkit) and app unit tests. Use when adding or fixing Go tests, implementing internal/repo or internal/app, designing table-driven tests, writing benchmarks, using testify, or improving coverage in this workspace.
Skill Claude CodeCodex
Build modern Next.js (16, App Router) apps with React Server Components. Use when creating or reviewing Next.js routes, layouts, server/client components, data fetching, Server Actions, caching, or metadata in the frontend app.
Skill Claude CodeCodex
Optimize React/Next.js runtime performance — eliminate waterfalls, shrink bundles, cut unnecessary re-renders, and speed up rendering. Use when writing, reviewing, or refactoring components for speed, or chasing slow renders, large bundles, janky interactions, or high TTFB/LCP/INP.
Skill Claude CodeCodex
Apply named refactoring transformations to improve structure without changing behavior. Use when refactoring Go or TypeScript in this workspace, identifying code smells, or preparing code for a new feature. Requires tests first — pair with working-with-legacy-code when coverage is missing.
Skill Claude CodeCodex
Build production-ready services: timeouts, circuit breakers, bulkheads, retry budgets, health checks, and observability. Use when hardening RonyKit services for production, reviewing outbound calls, capacity planning, or preventing cascading failures. Pair with MCP characteristics/telemetry and package x/ratelimit…
Skill Claude CodeCodex
Build UI with shadcn/ui — find, install, compose, and customize components using the correct CLI and patterns. Use when adding or styling frontend components, building forms/dashboards, theming, or working with components.json and the shadcn registry/MCP.
Skill Claude CodeCodex
Author and maintain Storybook stories with CSF 3.0 best practices — args, decorators, parameters, and config. Use when creating or editing .stories. files, configuring .storybook/, or ensuring every UI component ships with stories.
Skill Claude CodeCodex
Find the root cause before changing code. Use when encountering any bug, test failure, crash, flaky test, performance regression, or unexpected behavior, before proposing or applying a fix.
Skill Claude CodeCodex
Get screen typography correct — the details models reliably get wrong: curly quotes, en/em dashes, real ellipses, line length, line-height, hierarchy, and the JSX entity trap. Use whenever generating or reviewing HTML/CSS/React with visible text (landing pages, components, docs, dashboards) — apply the rules…
Skill Claude CodeCodex
Make web UI actually usable and accessible — keyboard/focus, interaction and loading states, forms, navigation, and motion. Use when building or reviewing any interactive surface (forms, modals, menus, tables, flows) for usability, accessibility (WCAG), interaction states, or the "it looks fine but feels janky / fails…
Skill Claude CodeCodex
Require fresh verification evidence before claiming work is done, fixed, or passing. Use before reporting completion, expressing success, committing, or opening a PR — run the command, read the output, then make the claim.
Skill Claude CodeCodex
Build agent-friendly web apps with the W3C Web Model Context API (WebMCP). Use when exposing frontend features as structured tools for in-browser AI agents, adding document.modelContext tools to React/Next.js apps, designing tool schemas for dashboards or admin UIs, or making existing UI automatable without DOM…
Skill Claude CodeCodex
Safely change untested code: seams, characterization tests, sprout/wrap, and the legacy change algorithm. Use when a RonyKit module lacks tests, you are afraid to touch existing behavior, or you need a safety net before refactoring. Pair with go-testing for repo integration and app unit tests.
