components

Guidance for building reusable React interface components that can be combined and used with assistive technologies. React is a tool for building web interfaces, and accessibility means making them usable by people with disabilities.

In plain words
What is it for?
Creating or updating reusable buttons, navigation, lists, and other components with keyboard support, screen-reader support, and data attributes.
Why use it?
It helps prevent components that are difficult to use with keyboards or screen readers. It also encourages standard HTML elements and appropriate ARIA attributes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

components scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to components — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Accessibility

URL: /accessibility

title: Accessibility description: Building components that are usable by everyone, including users with disabilities who rely on assistive technologies.

Accessibility (a11y) is not an optional feature—it's a fundamental requirement for modern web components. Every component must be usable by everyone, including people with visual, motor, auditory, or cognitive disabilities.

This guide is a non-exhaustive list of accessibility principles and patterns that you should follow when building components. It's not a comprehensive guide, but it should give you a sense of the types of issues you should be aware of.

If you use a linter with strong accessibility rules like Ultracite, these types of issues will likely be caught automatically, but it's still important to understand the principles.

Core Principles

  1. Semantic HTML First - Use native elements (<button>, <nav>, <ul>) for built-in accessibility
  2. Keyboard Navigation - Support Tab, Arrow keys, Home/End, Escape, Enter/Space for all interactions
  3. Screen Reader Support - Use ARIA attributes (aria-label, aria-current, aria-live) for proper announcements
  4. Visual Accessibility - Ensure focus indicators, sufficient contrast (4.5:1), and responsive text sizing

ARIA Patterns

ARIA enhances semantic HTML for assistive technologies. Key rules:

  1. Use semantic HTML first, ARIA only when necessary
  2. Don't override native semantics
  3. All interactive elements need keyboard access and accessible names

Common Attributes:

  • Roles - Define element type (role="button", role="navigation", role="alert")
  • States - Describe current state (aria-checked, aria-expanded, aria-selected)
  • Properties - Provide context (aria-label, aria-describedby, aria-controls, aria-required, aria-invalid)

Component Patterns

Complex interactive components require specific accessibility patterns. For detailed implementations, consult WAI-ARIA Authoring Practices.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

components is a skill published in the GitHub repository udecode/plate-template (59 stars, last pushed 2mo ago), licensed MIT. It adds 33 tokens to every session and 10,704 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to components, differing in 0 lines, and is treated as a copy.
