Web & Frontend

pdovhomilja Skill

Build accessible user interfaces using semantic HTML, ARIA attributes, keyboard navigation, and proper color contrast. Use this skill when creating or modifying UI components, implementing forms and interactive elements, working with navigation menus, building modals and dialogs, adding images and media content, writing JSX/HTML markup, ensuring keyboard accessibility, testing with screen readers, managing focus states, implementing proper heading hierarchies, providing alternative text for images, maintaining color contrast ratios, using ARIA labels and roles, or ensuring all interactive elements are keyboard-navigable. Apply this skill when building frontend components, reviewing UI accessibility, refactoring markup for better semantics, or implementing WCAG compliance requirements.

primer Skill

Use when: building, modifying, or wrapping compound components that use child-component "slots" in Primer React. Covers when to add a `__SLOT__` marker, the `useSlots` hook, the `isSlot` helper, the `asSlot` wrapper helper, naming conventions for slot symbols, and common pitfalls.

primer Skill

Use when: starting, checking, or using the Storybook dev server; looking up Primer React component stories, props, or documentation; previewing component variants; writing or verifying Storybook stories; using the primer-storybook MCP to explore components. Covers starting Storybook, checking if it is running, and using MCP tools (list-all-documentation, get-documentation, get-storybook-story-instructions, preview-stories) to look up components.

primer Bundle

Use when: authoring, modifying, or reviewing Primer React components, hooks, utilities, or component APIs.

primer Skill

primer Skill

Use when: implementing, creating, testing, or debugging feature flags in Primer React. Covers useFeatureFlag hook, FeatureFlags provider, DefaultFeatureFlags, FeatureFlagScope, Storybook integration, and the feature flag lifecycle at GitHub.

primer Skill

Use when: extracting, reusing, or naming hooks, state management, or other component-agnostic behavior in Primer React, or when a component's behavior hook wraps a native element with built-in behavior such as `<dialog>`. Covers the compound behavior-hook pattern (prop-getters), the controlled component contract for wrapping native elements, the difference between a component's own hook and a generic reusable utility, naming conventions, and where utilities live in the package.

primer Skill

Use when: building or evaluating unstyled Primer React primitives, especially accessibility primitives or low-level behavior that other components should build on. Covers when to create a base component instead of baking behavior into a styled component, the unstyled CSS-reset convention, deciding which parts need a base equivalent, and consolidating ARIA Authoring Practices Guide patterns.

primer Skill

Use when: building or evaluating a props-based, "all-in-one" Primer React component for an established, stable pattern. Covers when config components are appropriate, opinionated defaults, the props-driven customization surface, escape hatches to presentational components, and composing rather than duplicating behavior.

primer Skill

Use when: determining which Primer React API type (config, presentational, base, or utility) should own a specific accessibility responsibility, or documenting that ownership for a new component. Covers a responsibility matrix mapping ARIA requirements to API types, worked examples for Dialog and Tabs, and how to build a matrix for a new ARIA pattern.

primer Skill

Use when: building or evaluating flexible, composable Primer React parts that consumers assemble directly, or deciding whether a pattern is ready to become a config component. Covers structure-first composition, pairing presentational components with behavior hooks, data-component attributes, sub-component export conventions, and when to promote a pattern up the spectrum.

tmchow Bundle

Explore radically different design approaches for any page, component, or feature. Use when the user wants to compare multiple distinct visual directions side by side — not build one specific thing, but see several fundamentally different takes on the same UI. Signals: "explore designs for", "show me different ways to design", "radically different approaches", "what could this look like", "design exploration", "let's see some options before we commit", "different layout approaches", "different visual identities for the same content", wanting to see multiple families or variations before choosing a direction. Also triggers when the user pastes design exploration feedback (starts with "## Design Exploration Feedback") to iterate on a previous round, or pastes a design direction ("## Design Direction") to finalize. Do NOT trigger for building one specific design, visual refreshes, design critiques, brainstorming without visual output, single widget prototypes, or comparing CSS frameworks.

tmchow Skill

The craft of building design exploration prototypes. Covers file structure, control wiring, styling conventions, and output validation. Preloaded into the html-prototyper agent. Not intended for direct invocation.

us Skill

Scrape a single known URL into clean markdown / HTML / links / structured JSON with fastCRW. Use when you already have the URL and want the page content — "scrape", "grab", "fetch", "pull", "read this page", "get the content of". Handles JavaScript-rendered SPAs automatically. Step 2 of the crw workflow ladder.

us Skill

Programmatic web search and scrape with context isolation. Use for any research task where you need to search the web, filter results, and extract specific information — without flooding your context window with raw HTML and boilerplate. This is the single biggest token-saver in the crw skill set. Triggered by "search for", "look up", "find", "research", "what's the latest on", or any query that requires current web information. Also use when asked to "search and filter", "find the important parts", or any task where you suspect the raw output will be large (multi-page scrapes, news aggregation, competitive research).

workshop-gbb Bundle

Inspect local or remote website design, identify layout, responsive, accessibility, and visual consistency defects, and make source-level fixes. Use when users ask to "review website design", "check the UI", "fix the layout", "find design problems", or validate a web page after changes.

workshop-gbb Bundle

Establish product evidence, design contracts, complete UI states, anti-generic interface gates, and routing for frontend work. Use this skill when a material web, PWA, mobile, or desktop design, implementation, or quality request begins, before loading a narrower frontend domain skill.

jamiebrynes7 Bundle

Conduct rigorous, adversarial code reviews. Use when users ask to "critically review" my code or a PR, "critique my code", "find issues in my code", or "what's wrong with this code". Identifies security holes, lazy patterns, edge case failures, and bad practices. Scrutinizes error handling, type safety, performance, accessibility, and code quality. Provides structured feedback with severity tiers (Blocking, Required, Suggestions) and specific, actionable recommendations.

jal-co Bundle

Build Remotion videos with remocn — a shadcn registry of copy-paste animation components and timeline-driven UI primitives. Use when composing video scenes, adding text animations, transitions, backgrounds, UI blocks, brand/social cards, or full compositions in a Remotion project. Triggers include "remocn", "video component", "add animation", "text reveal", "scene transition", "product demo video", "remotion component", "typewriter", "terminal simulator", "glass code block", and the UI-primitive tier: "video dialog", "video button", "command menu", "video select", "video tooltip". Even if the user doesn't mention remocn, activate when they need polished video primitives for Remotion.

bholmesdev Bundle

Builds reusable Convex components with isolated tables and app-facing APIs. Use for new components, reusable backend modules, integrations, or component boundary work.

ninthless Bundle

Create, generate, write, update, rewrite, reconcile, or review an API document or contract from routes, handlers, schemas, types, client calls, tests, runtime evidence, OpenAPI/Swagger, GraphQL, gRPC, webhooks, AsyncAPI, or messages. Use when the final artifact is an API reference, endpoint documentation, API specification, frontend-to-backend or backend-to-frontend handoff, integration guide, or API documentation review. Trigger Chinese requests such as 接口文档, API文档, 接口说明, 接口契约, 接口规范, 接口对接文档, 根据前端生成接口文档, 根据后端代码补齐接口文档, and documentation work phrased as 整理, 补齐, 重写, 对接, or review. Document only evidence-supported behavior; never invent fields, constraints, permissions, errors, side effects, or deployment status. Do not trigger for endpoint/client/SDK implementation, webpage changes, tests, ordinary source review, bug diagnosis, generic HTTP teaching, API research without a documentation deliverable, translation, or incidental API mentions.
