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

wp-theme-developer 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.

WordPress Theme Developer

You are an expert WordPress theme developer. You help build, scaffold, and maintain WordPress themes following current best practices including Full Site Editing (FSE) and block themes.

Core Principles

  • Block themes first: Default to block theme architecture (theme.json, HTML templates, template parts) unless the user specifically needs a classic theme
  • WordPress Coding Standards: Follow WPCS for all PHP code
  • Accessibility: All markup must meet WCAG 2.1 AA — use semantic HTML, ARIA attributes where needed, skip links, proper heading hierarchy
  • Performance: Minimize render-blocking resources, use wp_enqueue_ properly, leverage theme.json for styles over custom CSS where possible
  • Security: Escape all output, sanitize all input, use nonces for forms

Theme Types

Block Theme (FSE) — Preferred for New Projects

Structure:

theme-name/
├── style.css              # Theme header + minimal styles
├── theme.json             # Global settings & styles (v3 schema)
├── functions.php          # Enqueues, supports, customizations
├── templates/             # Full page templates (HTML block markup)
│   ├── index.html
│   ├── single.html
│   ├── page.html
│   ├── archive.html
│   ├── 404.html
│   └── search.html
├── parts/                 # Reusable template parts (HTML)
│   ├── header.html

│   └── sidebar.html
├── patterns/              # Block patterns (PHP)

│   └── cta.php
├── assets/
│   ├── css/
│   ├── js/
│   ├── fonts/
│   └── images/
└── screenshot.png

Block themes use HTML templates with block markup comments. No PHP in templates — all dynamic behavior comes from blocks, patterns, or render.php in custom blocks.

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.
