spekka: Skill for Claude Code

.claude/skills/spekka-frontend-accessibility/SKILL.md

Frontend Accessibility is a skill for Claude Code from johnreitano/spekka. It costs 24 tokens per session (239 once invoked), scanned A, original, MIT.

Frontend accessibility guidance for building web pages and interfaces that people with disabilities can use, including with keyboards and screen readers.

In plain words
What is it for?
Use it when creating or reviewing HTML interfaces, forms, images, menus, modals, and single-page applications. It covers semantic HTML, keyboard access, alternative text, screen-reader checks, ARIA, and focus management.
Why use it?
It helps prevent interfaces that are difficult or impossible to use because of missing labels, poor colour contrast, confusing headings, or lost keyboard focus.

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

Frontend Accessibility 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 10d 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.

What it actually says

Frontend Accessibility

This Skill provides Claude Code with specific guidance on how it should handle frontend accessibility.

Instructions

  • Semantic HTML: Use appropriate HTML elements (nav, main, button, etc.) that convey meaning to assistive technologies
  • Keyboard Navigation: Ensure all interactive elements are accessible via keyboard with visible focus indicators
  • Color Contrast: Maintain sufficient contrast ratios (4.5:1 for normal text) and don't rely solely on color to convey information
  • Alternative Text: Provide descriptive alt text for images and meaningful labels for all form inputs
  • Screen Reader Testing: Test and verify that all views are accessible on screen reading devices.
  • ARIA When Needed: Use ARIA attributes to enhance complex components when semantic HTML isn't sufficient
  • Logical Heading Structure: Use heading levels (h1-h6) in proper order to create a clear document outline
  • Focus Management: Manage focus appropriately in dynamic content, modals, and single-page applications

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.
