About this skill

Opquast Digital Quality Best Practices

Canonical source: examples/OPQUAST_DIGITAL_QUALITY_BEST_PRACTICES.md in mgifford/ACCESSIBILITY.md This skill is derived from that file. When in doubt, the example is authoritative.

Apply the Opquast Digital Quality Checklist (Version 5, 2025-2030) when building or reviewing web projects. The framework contains 245 rules across 14 categories covering content, privacy, e-commerce, forms, accessibility, security, performance, and more.

Severity Scale (this skill)

LevelMeaning
CriticalCompletely blocks access, purchase, or task completion for a user group
SeriousSignificantly impairs access or usability; workaround unreasonable to expect
ModerateCreates friction; workaround available but burdensome
MinorBest-practice gap; marginal impact

Category-level severity guidance:

  • Security failures (HTTPS, headers, passwords): Critical to Serious
  • Forms failures (labels, error handling): Critical to Serious
  • Navigation failures (keyboard, focus): Critical to Serious
  • Images/Media missing alt/captions: Critical
  • Privacy policy missing: Serious
  • Presentation contrast: Serious; zoom blocked: Serious
  • Content, Links, Identification: Moderate to Minor in most cases
  • Server/Performance, Newsletter, Internationalisation: Minor in most cases

When to Use This Skill

  • Building a new website or web application
  • Reviewing or auditing an existing site for quality
  • Implementing accessibility, security, or privacy features
  • Creating e-commerce flows, forms, or navigation systems
  • Generating HTML/CSS code that must meet quality standards

Workflow

1. Identify Applicable Categories

Not all 14 categories apply to every project:

  • All web projects: Content, Forms, Identification, Images/Media, Links, Navigation, Presentation, Security, Server/Performance, Structure/Code
  • Add if applicable: E-Commerce (online sales), Newsletter (email marketing), Internationalisation (multi-language), Personal Data/Privacy (user accounts/data collection)

2. Consult the Full Rule Text

For the complete rule text, code examples, and rule numbers, consult the canonical Opquast guide or the official checklist directly — this skill summarizes the categories and highest-value patterns rather than reproducing all 245 rules verbatim.

3. Apply During Development

When generating or reviewing code, apply rules as implementation requirements:

  • HTML generation: Include metadata, semantic structure, accessible forms, proper alt text
  • CSS generation: Ensure contrast ratios, focus styles, responsive layout, print styles
  • Server configuration: Set security headers, enable compression, configure caching
  • Content review: Check date formats, link text, abbreviation expansion

4. Validate

After implementation, verify against applicable rules. Common automated checks:

  • HTML validation and heading hierarchy
  • Colour contrast ratios (4.5:1 normal text, 3:1 large text)
  • Missing alt attributes
  • Missing form labels
  • Security headers present
  • Broken internal links

Essential Code Patterns

Page Template Minimum

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8" />
  <meta name="viewport" content="width=device-width, initial-scale=1" />
  <meta name="description" content="Page description here." />
  <meta property="og:title" content="Page Title | Site Name" />
  <meta property="og:description" content="Page description for sharing." />
  <title>Page Title | Site Name</title>
  <link rel="icon" type="image/svg+xml" href="/favicon.svg" />
</head>
<body>
  <a href="#main" class="skip-link">Skip to main content</a>
  <nav aria-label="Main navigation"><!-- ... --></nav>
  <main id="main"><!-- ... --></main>
  <footer>
    <a href="/privacy">Privacy Policy</a>
    <a href="/terms">Terms of Use</a>
  </footer>
</body>
</html>

Accessible Form Field

Use native required on native inputs. aria-required is redundant when required is present and should be omitted to avoid accessibility tree noise (rule 98 principle: don't add ARIA states that duplicate native semantics). Use aria-required only on custom widgets (role="combobox" etc.). Also indicate required state in visible text — an asterisk alone is insufficient unless the convention is explained (rule 71).

<label for="email">
  Email address <span aria-hidden="true">*</span> <span class="hint">(required)</span>
  <span class="hint" id="email-hint">Example: [email protected]</span>
</label>
<input id="email" type="email" autocomplete="email"
  required aria-describedby="email-hint" />

Password Field (rules 75–76, 202–205)

<label for="password">Password</label>
<div class="password-wrapper">
  <input id="password" type="password" aria-describedby="password-hint" />
  <button type="button" aria-controls="password" aria-pressed="false">
    Show password
  </button>
</div>

Security Headers (Server Config)

Strict-Transport-Security: max-age=31536000; includeSubDomains; preload
X-Content-Type-Options: nosniff
X-Frame-Options: SAMEORIGIN
Content-Security-Policy: default-src 'self';
Referrer-Policy: strict-origin-when-cross-origin

Do not expose server software versions in response headers (rule 213) — remove or obfuscate Server and X-Powered-By. Apply Subresource Integrity to third-party scripts/stylesheets (rule 214):

<script src="https://cdn.example.com/library.min.js"
  integrity="sha384-<hash>" crossorigin="anonymous"></script>

Focus and Contrast Styles

:focus-visible {
  outline: 3px solid #005fcc;
  outline-offset: 2px;
}
body {
  color: #1a1a1a; /* ~16:1 contrast on white */
  background: #ffffff;
}

Print Styles

@media print {
  nav, header, footer, .sidebar, .no-print { display: none; }
  body { font-size: 12pt; color: #000; }
  a[href]::after { content: " (" attr(href) ")"; }
}

Accessible Data Table (rules 242–243)

<table>
  <caption>Quarterly revenue by region (USD thousands)</caption>
  <thead>
    <tr><th scope="col">Region</th><th scope="col">Q1</th></tr>
  </thead>
  <tbody>
    <tr><th scope="row">North America</th><td>1,200</td></tr>
  </tbody>
</table>

WCAG Relationship

Opquast complements WCAG 2.2 rather than replacing it. Key mappings:

When not to use it

  • When the project is not a website or web application
  • When the focus is solely on WCAG 3.0 without Opquast v5 considerations

Limitations

  • The skill is limited to the 245 rules defined in the Opquast Digital Quality Framework (Version 5, 2025-2030).
  • The skill does not cover WCAG 3.0, which is in development.

How it compares

This workflow systematically applies a predefined set of 245 rules with a severity scale, unlike a manual review that might miss specific checks or lack consistent issue grading.

graphql

davila7

GraphQL gives clients exactly the data they need - no more, no less. One endpoint, typed schema, introspection. But the flexibility that makes it powerful also makes it dangerous. Without proper controls, clients can craft queries that bring down your server. This skill covers schema design, resolvers, DataLoader for N+1 prevention, federation for microservices, and client integration with Apollo/urql. Key insight: GraphQL is a contract. The schema is the API documentation. Design it carefully.
