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

code-quality 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 6d 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.

Domain 2: Code Quality & Standards

2.1 WordPress Coding Standards (WPCS)

  • PHP code adheres to WordPress PHP Coding Standards
  • JavaScript follows WordPress JS Coding Standards
  • CSS follows WordPress CSS Coding Standards
  • HTML follows WordPress HTML Coding Standards
  • Yoda conditions used for comparisons (if ( true === $var ))
  • Proper indentation (tabs, not spaces for PHP; as per standard for JS/CSS)
  • PHPDoc blocks present for all functions, classes, methods, hooks
  • Text domain consistency for internationalization

2.2 Static Analysis

  • PHPCS with WordPress-Extra and WordPress-VIP-Go rulesets
  • PHPStan at level 6+ (ideally max) with WordPress extensions
  • Psalm analysis for type safety
  • ESLint for JavaScript with WordPress preset
  • Stylelint for CSS/SCSS

2.3 Architecture & Design Patterns

  • Proper use of WordPress hooks system (actions and filters) — no function overriding via copy-paste
  • Single Responsibility Principle in custom classes
  • Proper namespacing to avoid function/class name collisions
  • Autoloading via PSR-4 or WordPress-compatible patterns
  • Data validation at boundaries (input validation, output escaping)
  • Proper separation of concerns (business logic vs presentation)
  • No business logic in template files
  • Proper use of WordPress transients API for caching expensive operations
  • Custom post types and taxonomies registered correctly with appropriate capabilities
  • Options API used correctly (autoloaded only when necessary)

2.4 Error Handling

  • Try/catch blocks around operations that can fail (API calls, file operations, database)
  • WordPress error pattern: return WP_Error objects rather than false or exceptions for API boundaries
  • Error conditions handled gracefully — no white screens
  • Admin notices for recoverable errors
  • Logging for non-recoverable errors without exposing details to users

2.5 Deprecated & Removed Functions

  • No use of functions deprecated in current WordPress version
  • No use of PHP functions deprecated in current PHP version
  • No use of MySQL functions replaced by MySQLi/PDO
  • mysql_* functions completely absent
  • create_function() replaced with closures
  • each() replaced with foreach

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.
