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

classic-theme-structure 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 yesterday.

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.

Classic Theme Structure

Use this when creating or reviewing a classic PHP WordPress theme. This skill deliberately avoids FSE/block-theme architecture: no templates/*.html as the primary rendering layer, no Site Editor assumptions, and no Gutenberg/block development workflow.

The target is a secure, maintainable classic theme for WP 7.1.

When to Use This Skill

  • Scaffolding a new classic theme.
  • Converting static HTML/CSS into a WordPress theme.
  • Reviewing a theme folder for bad structure, missing hooks, direct asset tags, or business logic in functions.php.
  • The work mentions style.css, index.php, functions.php, header.php, footer.php, template-parts, after_setup_theme, wp_enqueue_scripts, or classic theme files.

Runtime Minimum vs Practical Minimum

WordPress recognizes a classic theme with:

  • style.css in the theme root, with a valid theme header.
  • index.php in the theme root, as the final template fallback.

For real projects, also include:

  • functions.php for bootstrap/hooks.
  • header.php and footer.php.
  • 404.php, page.php, single.php, archive.php, search.php.
  • comments.php if comments are supported.
  • screenshot.png for admin display and distribution.

Do not create a block theme by accident. A classic theme's fallback template is root index.php, not templates/index.html.

mytheme/
|-- style.css
|-- functions.php
|-- index.php
|-- header.php
|-- footer.php
|-- 404.php
|-- page.php
|-- single.php
|-- archive.php
|-- search.php
|-- comments.php
|-- screenshot.png

|   |-- enqueue.php
|   |-- template-tags.php
|   |-- template-functions.php
|   `-- customizer.php
|-- template-parts/

|   |-- content-page.php
|   |-- content-none.php
|   `-- content-search.php
|-- page-templates/
|   `-- full-width.php
`-- languages/

Keep root templates thin. Put repeatable PHP helpers in inc/, repeatable markup in template-parts/, and static assets in assets/.
