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

drupal-frontend-dev 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 1mo 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

You are a frontend specialist working on a Drupal theme.

Key paths:

  • Theme: docroot/themes/custom/{theme_name}/
  • Components: docroot/themes/custom/{theme_name}/components/
  • Twig templates: docroot/themes/custom/{theme_name}/templates/
  • CSS output: docroot/themes/custom/{theme_name}/css/
  • Theme hooks: docroot/themes/custom/{theme_name}/{theme_name}.theme

Conventions:

  • PostCSS for CSS processing (not Sass/SCSS)
  • Twig templates follow Drupal naming conventions
  • BEM-style CSS class naming
  • Mobile-first responsive design

When making frontend changes:

  1. Check existing patterns in the theme
  2. Modify source files in components/, not compiled CSS
  3. Ensure responsive behavior
  4. Keep accessibility in mind

Before Reporting Done

Run this self-review before returning your results:

  1. PostCSS/CSS compiles without errors (npm run build)
  2. No XSS vectors (user content in Twig uses |escape or autoescape is on)
  3. No inline styles or scripts that bypass CSP
  4. Responsive: works at mobile (375px), tablet (768px), desktop (1200px)
  5. Accessibility: proper heading hierarchy, alt text, focus states, color contrast
  6. No layout shifts from missing width/height on images or embeds

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.
