wordpress-standards

A guide to WordPress coding conventions, including names, file organization, documentation, and text domains. WPCS is the WordPress Coding Standards used to check these conventions.

In plain words
What is it for?
Use it when organizing plugin files, naming functions and hooks, writing DocBlocks, or configuring WPCS.
Why use it?
It helps keep WordPress code consistent and avoids common naming, structure, and documentation mistakes.

Getting it into your agent

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

wordpress-standards 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.

WordPress Coding Standards & Conventions

This skill covers WordPress naming conventions, file organization, coding style, and documentation standards as defined by the WordPress Coding Standards (WPCS).

File Naming

Type Pattern Example
Class file class-{name}.php class-my-plugin-admin.php
Interface interface-{name}.php interface-my-plugin-handler.php
Trait trait-{name}.php trait-my-plugin-singleton.php
Template template-{name}.php template-full-width.php
Template part {section}-{name}.php content-single.php
Admin page admin-{page}.php admin-settings.php
Include descriptive lowercase helpers.php, post-types.php

Function & Hook Naming

All functions, hooks, and global variables must be prefixed with the plugin/theme slug:

// Functions: prefix_action_description — always include return types
function myplugin_register_post_types(): void {}
function myplugin_enqueue_admin_scripts(): void {}
function myplugin_get_option( string $key ): string {}

// Hooks: prefix/action_description
do_action( 'myplugin_after_save', $post_id );
$value = apply_filters( 'myplugin_option_value', $value, $key );

// Classes: Prefix_Descriptive_Name (or namespaced)
class MyPlugin_Admin_Settings {}
// Or with namespaces:
namespace MyPlugin\Admin;
class Settings {}

Naming Conventions

Element Convention Example
Functions snake_case with prefix myplugin_get_user_data()
Classes Upper_Snake_Case or namespaced MyPlugin_Data_Handler
Methods snake_case $this->get_items()
Constants UPPER_SNAKE_CASE with prefix MYPLUGIN_VERSION
Variables $snake_case $user_name
Options prefix_option_name myplugin_settings
Post meta _prefix_meta_key (leading _ = hidden) _myplugin_custom_field
Transients prefix_cache_key myplugin_api_response
Nonce actions prefix_action myplugin_save_settings
Text domain match plugin/theme slug my-plugin

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

wordpress-standards is a skill published in the GitHub repository iwritec0de/wp-dev (1 stars, last pushed 4mo ago), licensed MIT. It adds 121 tokens to every session and 5,663 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
